Editor’s note: Hey look, a new author. Here’s the first post from Raymond Xie, who joined us nearly a year ago. You may remember him from such concept demos as geo-fencing or Pebble watchface. Raymond has been busy at work and wants to share the work he did with telekinesis. Or something, you decide. Enjoy.
You put on a headband, stare at a ball, tilt your head back-forth and left-right . . . the ball navigates through a simple maze, rushing, wavering, changing colors, and finally hitting the target.
That is the latest creation out of AppsLab: Muse Sphero Driver. When it was first showed at OAUX Exchange during OOW, it amused many people, as they would call it “mind control” game.
Technically, it is your brainwave data (Electroencephalography – EEG) driving the Sphero (adjusting speed and changing color with spectrum from RED to BLUE, where RED: fast, active; BLUE: slow, calm); and head gesture (3d Accelerarometer- ACC) controlling the direction of Sphero movement. Whether or not you call that as “mind control” is up to your own interpretation.
You kind of drive the ball with your mind, but mostly brainwave noises instead of conscious thought. It is still too early to derive accurate “mind control” from EEG data out of any regular person, for the reasons:
1. For EEG at Scalp level, the noise-to-signal ratio is very poor;
2. Need to establish the correlation between EEG and mind activity.
But it does open up a dialog in HCI, such as voice-control vs mind-control (silence); or in Robotics, instead of asking machine to “see”/”understand”, we can “see”/”understand” and impersonate it with our mind and soul.
While it is difficult to read out “mind” (any mind activity) transparently, we think it is quite doable to map your mind into certain states, and use the “state” as command indirectly.
We may do something around this area. So stay tuned.
Meanwhile, you can start to practice Yoga or Zen, to get better noise-to-signal ratio, and to set your mind into certain state with ease.
