Is the Mi Band the Harbinger of Affordable #fashtech?

March 1st, 2016 2 Comments

So, here’s a new thing I’ve noticed lately, customizable wearables, specifically the Xiaomi Mi Band (#MiBand), which is cheap and completely extensible.

This happens to be Ultan’s (@ultan) new fitness band of choice, and coincidentally, Christina’s (@ChrisKolOrcl) as well. Although both are members of Oracle Applications User Experience (@usableapps), neither knew the other was wearing the Mi Band until they read Ultan’s post.

Since, they’ve shared pictures of their custom bands.

Christina’s charcoal+red Mi Band.

The Mi Band already comes in a wider array of color options that most fitness bands, and a quick search of Amazon yields many pages of wristband and other non-Xiaomi produced accessories. So, there’s already a market for customizing the $20 device.

And why not, given it’s the price of a nice pedometer with more bells and whistles and a third the cost of the cheapest Fitbit, the Zip, leaving plenty of budget left over for making it yours.

Both Christina and Ultan have been tracking fitness for a long time and as early adopters so I’m ready to declare this a trend, i.e. super-cheap, completely-customizable fitness bands.

Of course, as with anything related to fashion (#fashtech), I’m the last to know. Much like a broken clock, my wardrobe is fashionable every 20 years or so. However, Ultan has been beating the #fashtech drum for a while now, and it seems the time has come to throw off the chains of the dull, black band and embrace color again.

Or something like that. Anyway, find the comments and share your Mi Bands or opinions. Either, both, all good.

IoT Hackathon: Team Waterlytics’ Entry – Part 2/2

February 24th, 2016 Leave a Comment

Editor’s note: Our team participated in many of the Summer of Innovation events held by Laurie (@lsptahoe) and her team. Here’s Part 2 of Mark’s (@mvilrokx) project from the IoT Hackathon held at Oracle HQ, July 30-31. Enjoy.

After all the prep work for the IoT hackaton where we agreed on our use case and settled on the hardware we would be using, it was time to start the actual fun part: designing and coding!

Diane provided all the designs for the application, Joe built all the hardware and provided the “smarts” of the application and I was responsible for bringing it all together.

The hardware

Let’s start with the sketch of the whole hardware setup:

IoT Hackathon Piezo Sketch_bb

Basically the piezo is connected to the 1 analog input on the ESP8266 (A0) and to ground.  In parallel with the piezo we put a 1MΩ pull-down resistor to reduce possible signal noise, a 1µF capacitor to smooth out the piezo’s signal over time to improve readings and a 5.1V Zener diode to prevent the piezo from frying the ESP8266 (piezo’s can spike at 20~40V).  The piezo can then simply be attached to a pipe with some plumbers putty, ready to start sensing vibrations.

For our test setup, we created a closed circuit water flow with some copper pipes, a simple garden pump and a bucket of water, simulating an actual water system.

IMG_0834

This turned out to work great for research and the actual demonstration during the hackathon.

The software

ESP8266 WiFi Client

The whole reason for using the ESP8266 was to be able to connect the piezo to the cloud.  The ESP8266 can be flashed with a Lua based firmware called NodeMCU, which makes this whole process remarkably simple.  Just set the ESP8266 in Wifi STATION mode and then connect to a available WiFi, that’s it, 2 lines of (Lua) code:

wifi.setmode(wifi.STATION)
wifi.sta.config(<ssid>, <pwd>)

The board is now connected to the internet and you can perform e.g. REST API calls from it.  In practice, we implemented this slightly different because this isn’t very user friendly, but that’s outside the scope of this post.

All we had to do now was read the data from the piezo and send it via the internet to be processed and stored somewhere, e.g. on the Oracle Cloud IoT platform.  Unfortunately we didn’t have access to that platform so we had to build something ourselves, see next.

Initially the plan was to use REST API calls to send the data to our backend, but this turned out to be too heavy for the little ESP8266 board and we could only perform a few calls/second before it would freeze and reboot.

Instead, we opted to use the MQTT protocol (quote from http://mqtt.org/):

“MQTT is a machine-to-machine (M2M)/”Internet of Things” connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium…”

Sounds like a perfect match and the Lua firmware has build in support for MQTT!

We turned our ESP8266 into a MQTT Client and used CloudMQTT as our broker.  Once we switched to MQTT we were able to send data at a much higher frequency, but still not fast enough compared to the number of samples we wanted to collect from the piezo (100s/sec).

So instead of sending all the data we collect from the piezo to a backend, we decided to do some of the processing on the ESP8266 chip itself.  We would collect 100 samples and then calculate the mean, median and standard deviation of those and send that to the backend instead as fast as we could.  In the end it turned out that calculating the standard deviation was to much for the board and it started effecting our sampling frequency, so we just dropped that al together.

Piezo data is now being pushed from our little board to the broker, next we need to store that data into a database.  For this we need another MQTT client that listens to the messages from the ESP8266 and stores them as they arrive.  We used node.js and the MQTT.js package to create our client and hooked it up to a MongoDB.

This gave us the flexibility to change the data that gets sent from the board (which was just some JSON) without having to deal with DDL.  For example, we managed to cram extra attributes into the data sent from the ESP8266 that contained information about the pipe’s material (“copper” or “PVC”) and the location of the piezo on the pipe (“close to bend”) all without changing anything other than the code on the ESP8266 that captures this information.

This information would be useful in our model as different pipe materials or other characteristics could have an effect on it, although we didn’t get to use it for the Hackathon.

The final piece of the puzzle was to display all this information into a useful manner to the end user.

For this we had a web application that would connect to the MongoDB and process the information available there.  Users could monitor usage, per device or aggregated in any number of ways: devices could be group by restroom, floor, building, campus or company wide.

You could also aggregate by device type: shower, toilet, urinal etc.  A budget could be allocated, again for any of these levels and time line, e.g. 100 gallon/day/toilet or 100,000 gallon/quarter/building.  Notifications would get sent out when you go over a budgets or when “unusual” activity gets noticed, e.g. a device is nowhere neat it’s budget BUT it has used much more today than it normally does, which could indicate a leak.

Those were all the software parts that made up our final solution, here’s an overview:

Slide1Notice how this architecture allows us to easily scale the individual parts without effecting one another: we can scale up the number of sensors, scale the MQTT broker, scale the node.js server and scale the MongoDB.

One final component that we did not really get to highlight in the presentation during the hackathon is that the MQTT Client on the ESP8266 is configured to both send messages (the piezo data as we shown before) but also to receive messages.

This allowed us to control the sensors remotely, by sending it commands from the broker (through another MQTT Client).  As soon as you switched on an ESP8266 module, say “sensor1”, it would announce itself.  The node.js server would be listening to these messages and indicate in the database that “sensor1” is online and ready to accept commands.

From another MQTT client, controlled from a admin web application, we could then send a command to this specific ESP8266 and tell it to either start sensing and send data or stop.  This was done for practical purpose because we were producing so much data that we were in danger of running out of free capacity on CloudMQTT 🙂 but it turned out to be a very useful feature that we are planning to investigate further and implement in any future versions.

In the end, we didn’t win any prizes at the Hackathon but I did learn a lot about IoT and plan to use that in future projects here at the AppsLab, stay tuned for more blogposts on those projects.

Cheers,

Mark

A Wonderful Week in Australia

February 23rd, 2016 5 Comments

2016 has been a whirlwind so far, and February kept up the pace. Here’s a quick rundown of what we’ve been doing.

As we did last year, OAUX made a trip to APAC again this year to meet partners, customers and Oracle people, show our Expo of goodies and talk simplicity-mobility-extensibility, Glance, Scan, Commit and our overall goal of increasing user participation.

This year, Noel (@noelportugal) and I made the trip to Australia and spent an awesome, warm week in beautiful Sydney. Noel showed the portable Smart Office demo, including the Smart Badge, that we debuted at OpenWorld in October, and I showed a couple visualizations and Glance on a handful of devices.

image3

Don’t let the picture fool you. It was taken between the end of Jeremy’s (@jrwashley) talk, before the official start of the Expo, during lunch. Once people finished eating, the room filled up quickly with 80 or so partner attendees.

Want more? Read Ultan’s (@ultan) account of the partner extensibility day.

On the second day in the Sydney office, we got the chance to chat with local Oracle sales reps, consultants and architects, and I was lucky enough to meet Stuart Coggins (@ozcoggs) and Scott Newman (@lamdadsn) who read this blog.

It’s always invigorating to meet readers IRL. I’ve poured nine years into this blog, writing more than 2,000 posts, and sometimes the silence is deafening. I wonder who’s out there reading, so it’s always a treat.

Oh, and Stuart had a board with blicky lights, an IoT demo he’d shown a customer that day. So, I was immediately intrigued.

Turns out Stuart and Scott create demos similar to our own and share the same nerdy passions we do. To wit, check out the Anki car hack Stuart and some colleagues did for Pausefest 2016 in Melbourne earlier this month.

You’ll recall the Anki cars are one of latest favorite shiny toys to hack.

Overall, it was a great week. Special thanks to John P for hosting us and making the trip all the more fun.

While we were away, Thao (@thaobnguyen) and the HQ team hosted a group of analysts in the Cloud and Gadget Labs, including Vinnie Mirchandani (@dealarchitect), who posted a nice writeup, including the money quote:

A walkthrough of their UX lab was like that of Q’s workshop in Bond movies. An Amazon Echo, smart watches, several gestural devices point to further changes in interfaces. Our expectations are being shaped by rapidly evolving UX in our cars and homes.

Somewhere Noel feels warm and fuzzy because the Q-meets-Tony Stark aesthetic is exactly what he was hoping to capture in his initial designs for our Gadget Lab.

Fun fact, back in 2007 when Justin (@kestelyn) and I collaborated on the original blogger program for OpenWorld, Vinnie was active in the discussion. Small world.

Anyway, given all the excitement lately, I’m only now getting a chance to encourage you to read a post by Sarah Smart over on VoX about stuff, “Wearables, IoT push Oracle’s emerging tech development.”

So yeah, a lot going on, and conference season is just beginning. Stay tuned for more.

Put Glance on It

February 5th, 2016 Leave a Comment

Because I live in Portland, I’m often asked if “Portlandia” is accurate.

It is, mostly, and so it seems appropriate to channel an early episode to talk about Glance, our wearables framework.

Actually, Glance has grown beyond wearables to support cars and other devices, the latest of which is Noel’s (@noelportugal) gadget du jour, the LaMetric Time (@smartatoms).

Insert mildly amusing video here.

And of course Noel had to push Glance notifications to LaMetric, because Noel. Pics, it happened.

IMG_20160129_101740

The text is truncated, and I tried to take a video of the scrolling notification, but it goes a bit fast for the camera. Beyond just the concept, we’ll have to break up the notification to fit LaMetric’s model better, but this was only a few minutes of effort from Noel. I know, because he was sitting next to me while he coded it.

In case you need a refresher, here’s Glance of a bunch of other things.

IMG_20160202_141310-4

I didn’t have a separate camera so I couldn’t show the Android notification.

We haven’t updated the framework for them, but if you recall, Glance also worked on Google Glass and Pebble in its 1.0 version.

Come Visit the OAUX Gadget Lab

February 4th, 2016 Leave a Comment

In September 2014, Oracle Applications User Experience (@usableapps) opened a brand new lab that showcases Oracle’s Cloud Applications, specifically the many innovations that our organization has made to and around Cloud Applications in the past handful of year.

We call it the Cloud User Experience Lab, or affectionately, the Cloud Lab.

Our team has several projects featured in the Cloud Lab, and many of our team members have presented our work to customers, prospects, partners, analysts, internal groups, press, media and even schools and Girl and Boy Scout troops.

In 2015, the Cloud Lab hosted more than 200 such tours, actually quite a bit more, but I don’t have the exact number in front of me.

Beyond the numbers, Jeremy (@jrwashely), our group vice president, has been asked to replicate the Cloud Lab in other places, on the HQ campus and abroad at other Oracle campuses.

People really like it.

In October 2015, we opened an adjoining space to the Cloud Lab that extends the experience to include more hands-on projects. We call this new lab, the Gadget Lab, and it features many more of our projects, including several you’ve seen here.

In the Gadget Lab, we’re hoping to get people excited about the possible and give them a glimpse of what our team does because saying “we focus on emerging technologies” isn’t nearly as descriptive as showing our work.

So, the next time you’re at Oracle HQ, sign up for a tour of the Cloud and Gadget Labs and let us know what you think.

The MagicBand

February 3rd, 2016 Leave a Comment

Editor’s note: Here’s the first post from our new-ish researcher, Tawny. She joined us back in September, just in time for OpenWorld. After her trip to Disney World, she talked eagerly about the MagicBand experience, and if you read here, you know I’m a fan of Disney’s innovative spirit.

Enjoy.

Planning a Disney World trip is no small feat. There are websites that display crowd calendars to help you find the best week to visit and the optimal parks to visit on each of those days so you can take advantage of those magic hours. Traveling with kids? Visiting during the high season? Not sure which FastPass+ to make reservations for?

There are annually updated guidebooks dedicated to providing you the most optimal attraction routes and FastPass+ reservations, based off of thousands of data points for each park. Beginning 2013, Disney introduced the MagicBand, a waterproof bracelet that acts as your entry ticket, FastPass+ holder, hotel key and credit card holder. The bands are part of The MyMagic+ platform, consisting of four main components: MagicBands, FastPass+, My Disney Experience, and PhotoPass Memory Maker. Passborterboard lists everything you can do with a MagicBand.

I got my chance to experience the MagicBand early this January.

 

These are both open edition bands. This means that they do not have customized lights or sounds at FP+ touchpoints. We bought them at the kiosk at Epcot after enviously looking on at other guests who were conveniently accessing park attractions without having to take out their tickets! It was raining, and the idea of having to take out anything from our bags under our ponchos was not appealing.

The transaction was quick and the cashier kindly linked our shiny new bands to our tickets. Freedom!!!

The band made it easy for us to download photos and souvenirs across all park attractions without having to crowd around the photo kiosk at the end of the day. It was great being able to go straight home to our hotel room while looking through our Disney photo book through their mobile app!

Test Track at Epcot made the most use of the personalization aspect of these bands. Before the rise, guests could build their own cars with the goal of outperforming other cars in 4 key areas: power, turn handling, environmental efficiency and responsiveness.

image003

After test driving our car on the ride, there were still many things we could do with our car such as join a multiplayer team race…we lost 🙁

What was really interesting were guests were fortunate to show off personalized entry colors and sounds, a coveted status symbol amongst MagicBand collectors. The noise and colors was a mini attraction on its own! I wish our badge scanners said hi to us like this every morning…

 

 

When used in conjunction with My Disney Experience app, there can be a lot of potential:

So what about MagicBands for the enterprise context?

Hospitals may benefit, but some argue that the MagicBand model works exclusively for Disney because of its unique ecosystem and the heavy cost it would take to implement it. The concept of the wearable is no different from the badges workers have now.

Depending on the permissions given to the badgeholder, she can badge into any building around the world.

What if we extend our badge capabilities to allow new/current employees to easily find team members to collaborate and ask questions?

What if the badge carried all of your desktop and environmental preferences from one flex office to the desk so you never have to set up or complain about the temperature ever again?

What if we could get a push notification that it’s our cafeteria cashier’s birthday as we’re paying and make their day with a “Happy Birthday?”

That’s something to think about.

M2M, the Other IoT

January 28th, 2016 1 Comment

Before IoT became ‘The’ buzzword, there was M2M (machine to machine). Some industries still refer to IoT as M2M, but overall the term Internet of Things has become the norm. I like the term M2M because it describes better what IoT is meant to do: Machines talking to other machines.

This year our team once again participated int he AT&T Developer Summit 2016 hackathon. With M2M in our minds, we created a platform to allow machines and humans report extraordinary events in their neighborhood.  Whenever a new event was reported (by machine or human),  devices and people (notified by an app) connected to the platform could react accordingly.  We came with two possible use cases to showcase our idea.

CX1FlaUUoAAuT6f

Virtual Gated Community

Gated communities are a great commodity for those wanting to have privacy and security. The problem is that usually these communities come with a high price tag. So we came up with a turnkey solution for a virtual gate using M2M. We created a device using the Qualcomm DragonBoard 410c board with wifi and bluetooth capabilities. We used a common motion sensor and a camera to detect cars and people not belonging to the neighborhood. Then, we used Bluetooth beacons that could be placed in at the resident keychains. When a resident drove (or walked) by the virtual gate, it would not trigger the automated picture and report to the system, but if someone without the Bluetooth beacon drove by, the system will log and report it.

We also created an app, so residents could get notifications as well as report different events, which brings me to our second use case.

Devices reacting to events

We used AT&T Flow Designer and M2X platform to create event workflows with notifications. A user or a device could subscribe to receive only events that they care about such as lost dog/cat, water leaks etc. The real innovative idea here is that devices can also react to certain events. For example, a user could configure its porch lights to automatically turn on when someone nearby reported suspicious activity. If everyone in their street do the same, it could be a pretty good crime deterrent to effectively being able to turn all the porch lights in the street at once by reporting such event.

We called our project “Neighborhood”, and we are still amazed on how much we were able to accomplish in merely 20+ hours.

SafeDrop – Part 2: Function and Benefits

January 25th, 2016 Leave a Comment

SafeDrop is a secure box for receiving a physical package delivery, without the need of recipient to be present. If you recall, it was my team’s project at the AT&T Developer Summit Hackathon earlier this month.

SafeDrop is implemented with Intel Edison board at its core, coordinating various peripheral devices to produce a secure receiving product, and it won second place in the “Best Use of Intel Edison” at the hackathon.

While many companies have focused on the online security of eCommerce, the current package delivery at the last mile is still very much insecure. ECommerce is ubiquitous, and somehow people need to receive the physical goods.

The delivery company would tell you the order will be delivered on a particular day. You can wait at home all day to receive the package, or let the package sit in front of your house and risk someone stealing it.

Every year there are reports of package theft during holiday season, but more importantly, the inconvenience of staying home to accept goods and the lack of peace of mind, really annoys many people.

With SafeDrop, your package is delivered, securely!

How SafeDrop works:

1. When a recipient is notified a package delivery with a tracking number, he puts that tracking number in a mobile app, which essentially registers it to SafeDrop box that it is expecting a package with that tracking number.

2. When delivery person arrives, he just scans the tracking number barcode on the SafeDrop box, and that barcode is the unique key to open the SafeDrop. Once the tracking number is verified, the SafeDrop will open.

3. When the SafeDrop is opened, a video is recorded for the entire duration when the door is open, as a security measure. If the SafeDrop is not closed, a loud buzz sound continues until it is closed properly.

Inside of SafeDrop: Intel Edison board, sensor, buzzer, LED, servo, and webcam

4. Once the package is within SafeDrop, a notification is sent to recipient’s mobile app, indicating the expected package has been delivered. Also shows a link to the video recorded.

In the future, SafeDrop could be integrated with USPS, UPS and FedEx, to verify the package tracking number for the SafeDrop automatically. When delivery person scans tracking number on SafeDrop, it automatically update status to “delivered” into that tracking record in delivery company’s database too. That way, the entire delivery process is automated in a secure fashion.

This SafeDrop design highlights three advantages:

1. Tracking number barcode as the key to the SafeDrop.
That barcode is tracked during the entire delivery, and it is with the package always, and it is fitting to use that as “key” to open its destination. We do not introduce any “new” or “additional” thing for the process.

2. Accurate delivery, which eliminates human mistakes.
Human error sometimes causes deliveries to the wrong address. With SafeDrop integrated into the shipping system, the focus is on a package (with tracking number as package ID) going to a target (SafeDrop ID associated with an address).

In a sense, the package (package ID) has its intended target (SafeDrop ID). The package can only be deposited into one and only one SafeDrop, which eliminates the wrong delivery issue.

3. Non-disputable delivery.
This dispute could happen: delivery company says a package has been delivered, but the recipient says that it has not arrived. The possible reasons: a) delivery person didn’t really deliver it; b) delivery person dropped it to a wrong address; c) a thief came by and took it; d) the recipient got it but was making a false claim.

SafeDrop makes things clear! If it is really delivered to SafeDrop, it is being recorded, and delivery company has done its job. If it is in the SafeDrop, the recipient has it. Really there is no dispute.

I will be showing SafeDrop at Modern Supply Chain Experience in San Jose, January 26 and 27 in the Maker Zone in the Solutions Showcase. If you’re attending the show, come by and check out SafeDrop.

My Joyful Consumption of Data

January 21st, 2016 4 Comments

I love data, always have.

To feed this love and to compile data sets for my quantified self research, I recently added the Netatmo Weather Station to the other nifty devices that monitor and quantify my everyday life, including Fitbit AriaAutomatic and Nest.

I’ve been meaning to restart my fitness data collection too, after spending most of last year with the Nike+ Fuelband, the Basis Peak, the Jawbone UP24, the Fitbit Surge and the Garmin Vivosmart.

FWIW I agree with Ultan (@ultan) about the Basis Peak, now simply called Basis, as my favorite among those.

Having so many data sets and visualizations, I’ve observed my interest peak and wane over time. On Day 1, I’ll check the app several times, just to see how it’s working. Between Day 2 and Week 2, I’ll look once a day, and by Week 3, I’ve all but forgotten the device is collecting data.

This probably isn’t ideal, and I’ve noticed that even something that I expected would work, like notifications, I tend to ignore, e.g. the Netatmo app can send notifications on carbon dioxide levels indoor, temperature outside and rain accumulation outside, if you have the rain gauge.

These seem useful, but I tend to ignore them, a very typical smartphone behavior.

Unexpectedly, I’ve come to love the monthly email many devices send me and find them much more valuable than shorter interval updates.

Initially, I thought I’d grow tired of these and unsubscribe, but turns out, they’re a happy reminder about those hard-working devices that are tirelessly quantifying my life for me and adding a dash of data visualization, another of my favorite things for many years.

Here are some examples.

Basis Weekly Sleep Report

A few years ago, Jetpack, the WordPress analytics plugin, began compiling a year in review report for this blog, which I also enjoy annually.

If I had to guess about my reasons, I’d suspect that I’m not interested enough to maintain a daily velocity, and a month (or a week for fitness trackers) is just about the right amount of data to form good and useful data visualizations.

Of course, my next step is dumping all these data into a thinking pot, stirring and seeing if any useful patterns emerge. I also need to reinvigorate myself about wearing fitness trackers again.

In addition to Ultan’s new fave, the Xiaomi Mi Band, which seems very interesting, I have the Moov and Vector Watch waiting for me. Ultan talked about the Vector in his post on #fashtech.

Stay tuned.

Any Port in a Storm: Novel Ways of Interacting with Our Devices

January 20th, 2016 1 Comment

With smartwatches, sometimes your fingers just aren’t good enough for the task at hand. Fortunately, some ingenious users have found a suitable alternative for when those digits just won’t do: their nose.

That thing sticking out from your face is enough like a fingertip to act as one in situations where your hands might be wet, dirty, or separated from your device by a layer of gloves.

A nose tap reenactment on the Apple Watch.

A nose tap reenactment on the Apple Watch.

Our own research, as well as that of Apple Watch research firm Wristly.co, has found users have occasionally resorted to their nose, and at reasonable numbers, too. Wristly found in one of their surveys that 46% of respondents had used their nose on their watch, and another 28% hadn’t, but were willing to try.

While users are probably not opting to use their nose when their fingers will do, this usage pattern fits into a larger question of how we interact with our devices: What’s the best way to interact with a device at any given time? When do we or should we use touch versus voice, gesture versus mouse, nose versus finger?

What I love about the nose tap is that it’s something that happened with users out in the real world, with real world situations. It’s doubtful this sort of usage would have been found in the lab, and may not have been considered when the Apple Watch was being designed. After all, with California’s beautiful weather, one might not consider what a glove-wearing population has to go through.

But now with this knowledge, designers should be asking themselves, “will my users ever need to nose tap? If so, how do I make sure it will work for them?” It sounds a little silly, but it could make an app or feature more useful to some users. And researchers should also be asking the same questions.

This goes for any novel, unexpected way users interact with any product, software or hardware: why are they doing it that way, and what is it telling us about their needs or underlying problems?

And the best way to find those novel, unexpected interactions? By seeing (or at least asking) how people use these products in the real world.

Seven Days with the Xiaomi Mi Band: A Model of Simple Wearable Tech UX for Business

January 18th, 2016 4 Comments

Worn Out With Wearables

That well-worn maxim about keeping it simple, stupid (KISS) now applies as much to wearable tech (see what I did there?) user experience as it does to mobile or web apps.

The challenge is to keep on keeping “it” simple as product managers and nervous C-types push for more bells and whistles in a wearable tech market going ballistic. Simplicity is a relative term in the fast changing world of technology. Thankfully, the Xiaomi Mi Band has been kept simple and the UX relates to me.

mi_with_apple_color

I first heard about the Mi Band with a heads-up from OAUX AppsLab chief Jake Kuramoto (@jkuramot) last summer. It took me nearly six months to figure out a way to order this Chinese device in Europe: When it turned in up Amazon UK.

topper

We both heard about the Mi from longtime Friend of the ‘Lab, Matt Topper (@topperge).

I’ve become jaded with the current deluge of wearable tech and the BS washing over it. Trying to make sense of wearable tech now makes my head hurt. The world and its mother are doing smartwatches and fitness trackers. Smartglasses are coming back. Add the wellness belts, selfie translators that can get you a date or get you arrested, and ingestibles into the mix; well it’s all too much to digest. There are signals the market is becoming tired too, as the launch of the Fitbit Blaze may indicate.

But after 7 days of wearing the Mi Band, I have to say: I like it.

Mi User Experience Es Tu User Experience

My Mi Band came in a neat little box, complete with Chinese language instructions.

Inside the little box: A big UX emerges.

Inside the little box: A big UX emerges.

Setup was straightforward. I figured out that the QR code in the little booklet was my gateway to installing the parent App (iOS and Android are supported) on my iPhone and creating an account. Account verification requires an SMS text code to be sent and entered. This made me wonder where my data was stored and its security. Whatever.

I entered the typical body data to get the Mi Band setup for recording my activity (by way of steps) and sleep automatically, reporting progress on the mobile app or by glance at the LEDs on the sensor (itself somewhat underwhelming in appearance. This ain’t no Swarovski Misfit Shine).

bmi

Enter your personal data. Be honest.

Metric, Imperial, and Jin locale units are supported.

Metric, Imperial, and Jin locale units are supported.

I charged up the sensor using yet another unique USB cable to add to my ever-growing pile of Kabelsalat, slipped the sensor into the little bracelet (black only, boo!), and began the tracking of step, sleep and weight progress (the latter requires the user to enter data manually).

I was impressed by simplicity of operation that was balanced by attention to detail and a friendly style of UX. The range of locale settings, the quality of the visualizations, and the very tone of the communications (telling me I was on a “streak”) was something I did not expect from a Chinese device. But then Xiaomi is one of the world’s biggest wearable tech players, so shame on me, I guess.

The data recorded seemed to be fairly accurate. The step count seemed to be a little high for my kind of exertion and my sleep stats seemed reasonable. The Mi Band is not for the 100 miles-a-week runners like me or serious quantified self types who will stick with Garmin, Suunto, Basis, and good old Microsoft Excel.

For a more in-depth view of my activity stats, I connected the Mi Band to Apple Health and liked what I saw on my iPhone (Google Fit is also supported). And of course, the Mi Band app is now enabled for social. You can share those bragging rights like the rest of them.

But, you guessed it. I hated the color of the wristband. Only black was available, despite Xiaomi illustrations showing other colors. WTF? I retaliated by ordering a Hello Kitty version from a third party.

The Mi Band seems ideal for the casual to committed fitness type and budding gym bunnies embarking on New Year resolutions to improve their fitness and need the encouragement to keep going. At a cost of about 15 US dollars, the Mi Band takes some beating. Its most easily compared with the Fitbit Flex, and that costs a lot more.

Beyond Getting Up To Your Own Devices

I continue to enjoy the simple, glanceable UX and reporting of my Mi Band. It seems to me that its low price is hinting at an emergent business model that is tailor-made for the cloud: Make the devices cheap or even free, and use the data in the cloud for whatever personal or enterprise objectives are needed. That leaves the fanatics and fanbois to their more expensive and complex choices and to, well, get up to their own devices.

So, for most, keeping things simple wins out again. But the question remains: how can tech players keep on keeping it simple?

2016 AT&T Developer Summit Hackathon: SafeDrop

January 15th, 2016 1 Comment

It has become tradition now for us, AppsLab, the OAUX emerging technologies team, that the first thing in a New Year is to fly to Las Vegas, not solely testing our luck on the casino floor (though some guys did get lucky), but also attending to the real business–participating in the AT&T Developer Summit Hackathon to build something meaningful, useful, and future-oriented, and hopefully get lucky and win some prizes.

Noel (@noelportugal), who participated in 2013, 2014 and last year, and his team were playing a grand VR trick–casting a virtual gate on a Real neighborhood–not exactly the VR as you know it, but rather, several steps deep into the future. Okay, I will just stop here and not spoil that story.

On the other side of desk, literately, David, Osvaldo (@vaini11a), Juan Pablo and I (@yuhuaxie) set our sights on countering Mr. Grinch with the Christmas package theft reports still fresh in people’s minds. We were team SafeDrop, and we forged carefully a safe box for receiving Christmas gift package. Unsurprisingly, we called it SafeDrop! And of course, you can use it to receive package deliveries other time of the year too, not just at Christmas time.

Team SafeDrop

Team SafeDrop (l-r), Os, David, me, Juan Pablo

In terms of the details of how the SafeDrop was built, and how you would use it, I will explain each in future posts, so stay tuned. Or shall I really explain the inner mechanism of SafeDrop and let Mr. Grinch have an upper hand?

By the way, team SafeDrop won the 2nd place of “Best Use of Intel Edison.” Considering the large scale of the AT&T Hackathon with over 1,400 participants forming 200+ teams, we felt that we were pretty lucky to win prizes. Each team member received a Basis Peak, a fitness watch you’ve read about here, and a Bluetooth headset, the SMS In-Ear Wireless Sport.

SafeDrop won 2nd place of Best Use of Intel Edison, with prizes

We know there are other approaches to prevent Mr. Grinch from stealing gifts, such as this video story shows: Dog poop decoy to trick holiday package thief. Maybe after many tries, Mr. Grinch would just get fed up with the smell and quit.

But we think SafeDrop would do the job by just the first try.

Stay tuned for more details of what we built.

VR Skeptic: 1994

January 9th, 2016 1 Comment

Here is a blast from the past: a letter I wrote to some friends back in 1994 about my very first VR experience.

VR enjoyed a brief spin as the next big thing that year. Jaron Lanier had been featured in the second issue of Wired magazine and virtual reality arcades began to appear in the hipper shopping malls. In short, it was as hyped and inevitable then as it is again today.

So with any further ado, here is my unedited account of what virtual reality was like in 1994:

A view of the Dactyl Nightmare playing field

A view of the Dactyl Nightmare playing field

 

For my birthday last weekend, Janine, Betsy, Tom and I tried an interesting experiment: a virtual reality arcade in San Francisco called Cyber Mind.

It was a pleasant enough little boutique, not overrun by pimply-faced hoards as I had expected. They had a total of ten machines, two sit-down, one-person flight simulator contraptions, and two sets of four networked platforms. We chose to play one of the four-person games called Dactyl Nightmare.

I stepped up on a sleek-looking platform and an attendant lowered a railing over my head so that I would not wander off while my mind was in other worlds. I then strapped on a belt with more equipment and cables and donned a six pound Darth-Vader-on-steroids helmet. The attendant placed a gun in my hand.

When they pulled the switch I found myself standing on a little chessboard floating in space. There were a total of four such platforms with stairs leading down to a larger chessboard, all decorated by arches and columns. I could look in any direction and if I held out my arm I could see a computer-generated rendition of my arm flailing around, holding a gun. If I pushed the thumb switch on top of the gun I began to walk in whatever direction I was looking in.

I began bumping into columns and stumbling down stairs. It wasn’t long before I saw Janine, Betsy, and Tom also stumbling around, walking with an odd gait, and pointing guns at me. The game, as old as childhood itself, was to get them before they could get me. Usually, by the time I could get my bearings and take careful aim, someone else (usually Betsy) had sneaked up behind me and blasted me into computer-generated smithereens. After a few seconds, I reformed and rejoined the hunt.

This happy situation was somewhat complicated by a large green Pterodactyl with the bad habit of swooping down and carrying off anyone who kept firing their guns into the ground (which was usually where I tended to fire). If you were true of heart and steady of aim you could blast the creature just before it’s claws sunk in. I managed this once, but the other three or four times I was carried HIGH above the little chessboard world and unceremoniously dropped.

After a quick six minutes it was all over. The total cost was $20 for the four of us, about a dollar per person per minute. I found the graphics interesting but not compelling and resolved to come back in a few years when the technology had improved.

I was not dizzy or disoriented during the game itself, but I emerged from my helmet slightly seasick, especially after the second round. This feeling persisted for the rest of the day. But it was a worthy experiment. Twenty dollars and a dizzy day: a small price to pay for my first glimpse at virtual reality.

VR Skeptic: Immersion and Serendipity

January 9th, 2016 1 Comment

 

John staring boldly into the future of VR

Look, I’m as fond of holodecks and the matrix as the next nerd. I was having queazy VR experiences back in 1994. That’s me just last month strapped into to a cheap plastic viewer, staring boldly into the future. I’ve been thinking and writing about virtual reality for over twenty years now.

But are we there yet? Is VR ready for mainstream adoption? And, aside from a few obvious niche cases, does it have any significant relevance for the enterprise?

This is the first of a series of “VR Skeptic” blog posts that will explore these questions. The AppsLab has already started to acquire some VR gear and is hunting for enterprise use cases. I’ll share what I find along the way.

So why am I a skeptic? Despite all the breathless reviews of the Oculus Rift over the last few years and the current hype storm at CES, the VR industry still faces many serious hurdles :

To this I would add what I’ve noticed about the user experience while sampling Google Cardboard VR content:

But every time I’m ready to give up on VR, something like this pulls me back: Google Cardboard Saves Baby’s Life  (hat tip to my colleague Cindy Fong for finding this).

Immersion and Serendipity

I think VR does have two unique qualities that might help us figure out where it could make an impact: immersion and serendipity.

Immersion refers to the distinct feeling of being “inside” an experience. When done well, this can be a powerful effect, the difference between watching a tiger through the bars of its cage and being in the cage with the tiger. Your level of engagement rises dramatically. You are impelled to give the experience your full attention – no multi-tasking! And you may feel a greater sense of empathy with people portrayed in whatever situation you find yourself in.

Serendipity refers to the potential for creative discovery amidst the jumbled overflow of information that tends to come with VR. A VR typically shows you more content than you can easily absorb, including many things you won’t even see unless you happen to be looking in the right direction at the right moment. This makes it harder to guide users through a fixed presentation of information. But it might be an advantage in situations where users need to explore vast spaces, each one using his or her instincts to find unique, unpredictable insights.

It might be fruitful, then, to look for enterprise use cases that require either immersion or serendipity. For immersion this might include sales presentations or job training. Serendipity could play a role in ideation (e.g. creating marketing campaigns) or investigation (e.g. audits or budget reconciliations where you don’t know what you’re looking for until you find it).

Collaboration

Because VR content and viewers are not yet ubiquitous, VR today tends to be a solitary experience. There are certainly a number of solitary enterprise use cases, but the essence of “enterprise” is collaboration: multiple people working together to achieve things no single person could. So if there is a killer enterprise VR app, my guess is that it will involve rich collaboration.

The most obvious example is virtual meetings. Business people still fill airports because phone and even video conferences cannot fully replace the subtleties and bonding opportunities that happen when people share a physical space. If VR meetings could achieve enough verisimilitude to close a tricky business deal or facilitate a delicate negotiation that would be a game changer. But this is a very hard problem. The AppsLab will keep thinking about this, but I don’t see a breakthrough anytime soon.

Are there any easier collaborations that could benefit from VR? Instead of meetings with an unlimited number of participants, perhaps we could start with use cases involving just two people. And since capturing subtle facial expressions and gestures is hard, maybe we could look for situations which are less about personal interactions and more about a mutual exploration of some kind of visualized information space.

One example I heard about at last year’s EyeO conference was the Mars Rover team’s use of Microsofts’s HoloLens. Two team members in remote locations could seem to be standing together in a Martian crater as they decide on where to send the rover to next. One could find an interesting rock and call the other over to look at it. One could stand next to a distant feature to give the other a better sense of scale.

Can we find a similar (but more mundane) situation? Maybe an on-site construction worker with an AR headset sharing a live 360 view with a remote supervisor with a VR headset. In addition to seeing what the worker sees, the supervisor could point to elements that the worker would then see highlighted in his AR display. Or maybe two office managers taking a stroll together through a virtual floor plan allocating cubicle assignments.

These are some of the ideas I hope to explore in future installments. Stay tuned and please join the conversation.

The Time I Ran Out of Gas

January 6th, 2016 Leave a Comment

Before Christmas, I ran out of gas for the first time.

All things considered, I was very lucky. It was just me in the car, and the engine died in a covered parking structure, in a remote corner with few cars. Plus, it was the middle of the day, during the week before Christmas, so not a lot of people were out and about anyway.

Could have been a lot worse.

The reason why I ran out of gas is more germane, and as a result of my mishap, I found another interesting experience.

I’ll start with the why. If you read here, you’ll know I’ve been researching the quantified self, which I understand roughly as the collection of data related to me and the comparison of these data sets to identify efficiencies.

As an example, I tracked fitness data with a variety of wearables for most of last year.

About a year ago, Ben posted his impressions of Automatic, a device you plug into your car’s OBD-II diagnostics port that will quantify and analyze your driving data and track your car’s overall health, including its fuel consumption and range.

I have since added Automatic my car as another data set for my #QS research. I’ve found the data very useful, especially with respect to real cost of driving.

Since Automatic knows when you fill the tank and can determine the price you paid, it can provide a very exact cost for each trip you make. This adds a new dimension to mundane tasks.

Suddenly, running out for a single item has a real cost, driving farther for a sale can be accurately evaluated, splitting the cost of a trip can be exact, etc.

One feature I appreciate is the range. From the wayback archives, in 2010, I discussed the experience and design challenges of a gas gauge. My Jeep warns of low fuel very early and won’t report the range once the low fuel indicator has been tripped.

However, Automatic always reports an estimated range, which I really like.

Screenshot_2016-01-04-14-24-12

Maybe too much, given this is how I ran out of gas. The low fuel indicator had been on for a day, but I felt confident I could get to a gas station with plenty of time, based on the estimated range reported by Automatic.

Armed with my false confidence, I stopped to eat on the way to the gas station, and then promptly ran out of gas.

To be clear, this was my fault, not Automatic’s.

In my 2010 musings on the gas gauge, I said:

It does seem to be nigh impossible to drive a car completely out of gas, which seems to be a good thing, until you realize that people account for their experiences with the gauges when driving on E, stretching them to the dry point.

Yeah, I’m an idiot, but I did discover an unforeseen negative, over reliance on data. I knew it was there, like in every other data vs. experience point-counter point. I know better than to rely on data, but I still failed.

Something I’ll need to consider more deeply as my #QS investigation continues.

Now for the interesting experience I found.

After calling roadside assistance for some gas, my insurance company texted me a link to monitor “the progress of my roadside event.” Interesting copy-writing.

That link took me an experience you might recognize.

Screenshot_2015-12-18-10-05-21

Looks like Uber, doesn’t it? Because it’s a web page, the tow trunk icon wasn’t animated like the Uber cars are, but overall, it’s the same, real-time experience.

I like the use here because it gives a tangible sense that help is on the way, nicely done.

So, that’s my story. I hope to avoid repeating this in the future, both the running-out-of-gas and the over-reliance on data.

Selfies. Social. And Style: Smartwatch UX Trends

January 5th, 2016 Leave a Comment

From Antiques to Apple

“I don’t own a watch myself,” a great parting shot by Kevin of Timepiece Antique Clocks in the Liberties, Dublin.

I had popped in one rainy day in November to discover more about clock making and to get an old school perspective on smartwatches. Kevin’s comment made sense. “Why would he need to own a watch?” I asked myself, surrounded by so many wonderful clocks from across the ages, all keeping perfect time.

This made me consider what might influence people to use smartwatches? Such devices offer more than just telling the time.

From antiques to Apple: UX research in the Liberties, Dublin

From antiques to Apple: UX research in the Liberties, Dublin

2015 was very much the year of the smartwatch. The arrival of the Apple Watch earlier in 2015 sparked much press excitement and Usable Apps covered the enterprise user experience (UX) angle with two much-read blog pieces featuring our Group Vice President, Jeremy Ashley (@jrwashley).

Although the Apple Watch retains that initial consumer excitement (at the last count about 7 million units have shipped), we need to bear in mind that the Oracle Applications User Experience cloud strategy is not about one device. The Glance UX framework runs just as well on Pebble and Android Wear devices, for example.

vectorpeak_plane-1

It’s not all about the face. Two exciting devices came my way in 2015 for evaluation against the cloud user experience: The Basis (left) and Vector Watch.

Overall, the interest in wearable tech and what it can do for the enterprise is stronger than ever. Here’s my (non-Oracle endorsed) take on what’s going to be hot and why in 2016 for smartwatch UX.

Trending Beyond Trendy

There were two devices that came my way in 2015 for evaluation that for me captured happening trends in smartwatch user experience.

First there was the Basis Peak (now just Basis). I covered elsewhere my travails in setting up the Basis and how my perseverance eventually paid off.

basis

Basis: The ultimate fitness and sleep tracker. Quantified self heaven for those non-fans of Microsoft Excel and notebooks. Looks great too!

Not only does the Basis look good, but its fitness functionality, range of activity and sleep monitoring “habits,” data gathering, and visualizations matched and thrilled my busy work/life balance. Over the year, the Basis added new features that reflected a more personal quantified self angle (urging users to take a “selfie”) and then acknowledged that fitness fans might be social creatures (or at least in need of friends) by prompting them to share their achievements, or “bragging rights,” to put it the modern way.

peaknotifications_25

Your bragging rights are about to peak: Notifications on Basis (middle).

Second there was the Vector Watch, which came to me by way of a visit to Oracle EPC in Bucharest. I was given a device to evaluate.

A British design, with development and product operations in Bucharest and Palo Alto too, the Vector looks awesome. The sophisticated, stylish appearance of the watch screams class and quality. It is easily worn by the most fashionable people around and yet packs a mighty user experience.

Vector Watch: Fit executive meets fashion.

Vector Watch: Fit executive meets fashion.

I simply love the sleek, subtle, How To Spend It positioning, the range of customized watch faces, notifications integration, activity monitoring capability, and the analytics of the mobile app that it connects with via Bluetooth. Having to charge the watch battery only 12 times (or fewer) each year means one less strand to deal with in my traveling Kabelsalat.

The Vector Watch affordance for notifications is a little quirky, and sure it’s not the Garmin or Suunto that official race pacers or the hardcore fitness types will rely on, and maybe the watch itself could be a little slimmer. But it’s an emerging story, and overall this is the kind of device for me, attracting positive comments from admirers (of the watch, not me) worldwide, from San Francisco to Florence, mostly on its classy looks alone.

I’m so there with the whole #fitexecutive thing.

Perhaps the Vector Watch exposes that qualitative self to match the quantified self needs of our well-being that the Basis delivers on. Regardless, the Vector Watch tells us that wearable tech is coming of age in the fashion sense. Wearable tech has to. These are deeply personal devices, and as such, continue the evolution of wristwatches looking good and functioning well while matching the user’s world and responding to what’s hot in fashion.

Heck, we are now even seeing the re-emergence of pocket watches as tailoring adapts and facilitates their use. Tech innovation keeps time and keeps up, too, and so we have Kickstarter wearabletech solutions for pocket watches appearing, designed for the Apple Watch.

The Three “Fs”

Form and function is a mix that doesn’t always quite gel. Sometimes compromises must be made trying to make great-looking, yet useful, personal technology. Such decisions can shape product adoption. The history of watch making tells us that.

Whereas the “F” of the smartwatch era of 2014–2015 was “Fitness,” it’s now apparent that the “F” that UX pros need to empathize with in 2016 will be “Fashion.” Fashionable technology (#fashtech) in the cloud, the device’s overall style and emotional pull, will be as powerful a driver of adoption as the mere outer form and the inner functionality of the watch.

The Beauty of Our UX Strategy

The Oracle Applications Cloud UX strategy—device neutral that it is—is aware of such trends, ahead of them even.

The design and delivery of beautiful things has always been at the heart of Jeremy Ashley’s group. Watching people use those beautiful things in a satisfied way and hearing them talk passionately about them is a story that every enterprise UX designer and developer wants the bragging rights to.

So, what will we see on the runway from Usable Apps in 2016 in this regard?

Stay tuned, fashtechistas!

AppsLab Research in 2015

January 4th, 2016 Leave a Comment

As we exit 2015 and enter 2016, I’m reflecting on all that happened in AppsLab and looking forward to the future. Our 2015 research spanned the spectrum – from attitudinal to behavioral, domestic to international, controlled to ad hoc, low to high tech, and many more research tactics. I won’t bore you with stats and an exhaustive list of studies. Rather, here is a brief recap of some of our research and interests.

We studied smartwatches a bit this year. We ran focus groups to gauge interest and identify use cases. We ran user journal studies to learn about user adoption and behavior patterns. We ran guerrilla usability studies with prototypes to evaluate features and interactions. We used stars and stickies to gather feedback. We used Oracle Social Research Management (SRM) to glean insight from social media.

ukougprize

Are you attending UKOUG Apps15 (#ukoug_apps15) or Tech15 (#ukoug_tech15)? If so, you are in luck! Once again we will run our ever popular scavenger hunt with a twist. From December 7-9 we will be at the ICC in Birmingham, UK working with the UKOUG team to give you a fun way to explore the conference and win prizes along the way.

man-gets-expo-stamp-on-his-arm

If you’re not familiar with this game, it is as if we are stamping a card (or your arm!) every time you do a task. But instead, we are using IoT technologies; Raspberry Pi, NFC stickers, and social media to give you points. This time we will hold a daily drawing. You only need to enter once, but the more tasks you complete the more chances you have to win. Each day has different tasks.

This is a great way to discover new things, make friends, and enjoy the conference from a different perspective.

You can pre-register here http://bit.ly/UKOUG15Explorer or come over during registration so we can set you up. See you there!

OpenWorld 2015 Highlights

November 19th, 2015 1 Comment

It’s been nearly three weeks, and I’m finally getting around to sharing the highlights of our OpenWorld 2015. Enjoy.

Keynotes

Last year, Steve Miranda showed some of our project work in his keynote. This year, our Glance framework on the Apple Watch, made an appearance in Larry Ellison’s first keynote in a video showcasing the evolution of Oracle’s User Experience over the last 30 years.

OTN Community Quest

Noel (@noelportugal) and I oversaw the OTN Community Quest during OOW and JavaOne this year.

Pic, it happened.

We registered more than 300 players. Of those, more than half completed more than one task, and we had 18 players finish all nine tasks.

One major change we made to the game after the Kscope15 Scavenger Hunt was to change from a points system to a drawing, allowing anyone to play, at any time during the game and have a good shot to win.

An unintentional proof point, the Grand Prize winner completed only one task.

Here’s a short video explaining what it was, how to play and why we did it.

I know Noel would like me to mention a cool feature for this iteration of the game.  He wrote some code to have the Amazon Echo draw the winning entries, which was a pretty sweet demo.

echoPis

Big thanks to our longtime and very good friends at OTN for letting us do this.

OAUX Exchange

Speaking of Alexa, the Amazon Echo’s persona and our favorite toy lately,  it featured prominently in the IoT Smart Office our team built to show at the OAUX Exchange.

Alexa and the smart badge were only parts of the whole experience, which included proximity using BLE beacons, voice-controlled environment settings and voice-controlled Cloud Applications navigation, just to hit the highlights.

The Smart Office wow feature was this Leap Motion interaction, grabbing a record from one screen and throwing it to another.

But wait, there was more. We showed the Glance Framework running on Android Auto, on an actual car head unit.

A Smart Badge for a Smart Office

November 9th, 2015 Leave a Comment

Editor’s note: Maybe you got a chance to check out our IoT Smart Office demo at the OAUX Exchange during OpenWorld. If not, don’t fret, we’ll describe its many cool bits here, beginning with this post from Raymond (@yuhuaxie) on his smart badge build. A Smart Office needs an equally smart badge.

We showcased the Smart Office at OAUX Exchange.

You put on a badge and walked into an office in the future, and everything came alive. You may be dazzled by the lights, screens, voice commands and gesture, and may not have paid any attention to the badge. Well, the badge is the key to start all the magical things when you approach the office. And it is worth some mention of its build.

The classical version:

If you tried it at the Exchange event, you can feel it is just like a normal badge, except it is a little heavier and has a vivid display.

Inside that home-made leather pouch, there is a 3.5” TFT display, a large recycled LiPo battery (taken out of a thin power bank we got at Kscope15), and one controller called LightBlue Bean (@punchthrough), which happened to be the same controller inside “Smart Bracelet” we showcased a year earlier to light up different colors to guide you an expo path.

The Smart Badge needs to be programmable and to tell its presence, so that we can program it to be a particular persona, and it can indicate to other listener (a Raspberry Pi server acting as IoT brain) about its presence or approaching to Smart Office.

The LightBlue Bean does the job perfectly, as it has two personalities: BLE and Arduino compatible controller. We created an iOS app to talk to the Bean over Bluetooth to set up persona, and the Arduino side of Bean would control the TFT display to show proper badge image.

bean_front

The Smart Badge

When the person wearing the Smart Badge approaches the office, the Raspberry Pi server would detect its coming, and can send out a remote notification to iPhone and Apple Watch, so that you can “check in” to the office from an Apple Watch, and then start the whole sequence of Smart Office coming alive.

At the OAUX Exchange event, due to limited space issue, we did not use BLE presence detection we built, but instead, we used a time-delay mechanism to send out notification to Apple Watch.

bean_back

Inside the Smart Badge

For those curious minds, we prepared another version, to show the components inside the Smart Badge. I would call it . . .

The techno version:

Instead of stacking up the components, we spread the components so people can see the parts and wiring. We designed and laser-cut acrylic sheets to make a transparent case, and it resembles the typical laminated badge you see at conferences.

As you can see, the wiring between the Bean and TFT is pretty much for the display control over SPI protocol, plus one wire to access SD card inside TFT display board, and another wire to control the backlight. The BLE part is all over wireless.

bean_demo

esp8266_demo

By the way, we made another version using ESP8266 (NodeMCU) instead of the Bean, because we just love the little ESP8266.

We connected the TFT display with NodeMCU over hardware SPI, and similar approach for access SD card and backlight control. Since NodeMCU has so many more pins available (some PWM pins too), we can actually control the backlight to dim at many brightness level, instead of just turning on and off, as in the Bean case.

The NodeMCU is flushed as an Arduino variant, and set up as a web server with its built-in wifi capability. The iOS app mentioned earlier can program this Smart Badge using HTTP request over wifi. In fact, it can be programmed using any browser or CLI, without the need of tethering to iPhone.

NodeMCU is such a recent toy on the block, that it takes some time to get it work with TFT display. For example, the image just does not look right when controlled by NodeMCU. After some perseverance, it was straightened out.

esp8266_experiment

The card version:

We were considering making the Smart Badge as small as possible. This design was to make it just a bit larger than the TFT display, by stacking NodeMCU behind TFT, and use a tiny proto-board to neatly wire everything. It is about the size of a deck of card, hosted in a transparent acrylic case.

Figured that it does not look like a badge, but it is a nice little display hooked on the Internet, that can sit on a desktop. So I decided to fit in a 3 x AAA everyday battery, instead of the LiPo battery which usually use JST connector and is a hassle to recharge.

esp8266_front

esp8266_back

Currently, this version can show a badge, also do some slide shows. But it can do much more – with NodeMCU (ESP8266), it is a web server that can listen for instructions, it is web client to pull information from outside, it runs MQTT to react to outside events, and it has many pins to hook up sensors and controllers. Plus that the TFT is a touch display, we can make touch input to switch to different modes, etc.

It could be a real functional Smart Office monitor/notification center.

I guess this is just the starting point of a little toy.
