I was intrigued when I saw the following video that looked more like a sneak peak into the future . They say that “It sounds too good to be true, we know. But, that’s what we specialize in around here.” One reason for me being so skeptical to believe what they claim is the fact that the present state of the art gesture recognition technologies are not capable of churning out something commercial like this . Also there is no word on their website to help us understand what kind of motion sensing technology they are using. If they really live up to their claim with out any hacks and if it is complete free motion 3D gesture recognition then it would truly be revolutionary.
Here are couple of interesting links to the discussion on what kind of technology they might be using. Most of them work on 3D processing and gesture recognition technologies so I believe their insights are valuable.
Quoting from the the discussions in those threads—
#”I’ve heard rumors they might be using something called electric field imaging. All I can find out about this technology is from these guys’ work: http://web.media.mit.edu/~jrs/efs.html. And that stuff was done in the 90’s. If they were able to track a hand back then, I guess over a decade someone could figure out how to track fingers as well. With the precision they’re boasting, I kind of doubt they are using time-of-flight camera’s or structured light…I could be wrong though”.
#”I think with a good structured light technique you might be able to get that accuracy. However, with 1/100th mm resolution, I cannot believe this thing can be powered off batteries over wireless, as hinted at in the video.”
#”I’ll take a wild guess that the operating principles have something to do with the theramin http://www.youtube.com/watch?v=w5qf9O6c20o but while the theramin only measures two capacitances, the Leap somehow is able to acquire and analyze multiple measurement channels to localize several objects”.
#”This definitely looks impressive. I am eager to see the hardware specifications – is it a camera? structured light? normal rgb? is it a sonar-like sensor, a laser”?
#”Very impressive! Possibly equipped with stereo or quadro IR cameras”.
# “It could be a more advanced version of this”. http://www.technologyreview.com/web/40368/?p1=A2
