... but meant that you had to sit infuriatingly still if you wanted to keep listening to the same program.
Skip the sensors, skip the cameras: if you watch the signals closely enough, you can build gesture recognition using only WiFi signals. That's what's just emerged from the University of Washington, where computer scientists say their WiSee technology can accurately recognise 94 percent of gestures from a sample of 900. They …
1)
"You always perform a startup sequence of gestures to get into the control system before sending the real gesture commands. The startup squence (sic) could be relatively long so false positives become rare cases. Such a startup sequence can also serve as your personal password."
There is no way to see you entered the RIGHT startup sequence before you send the commands, in particular if you are not in the same room as the WiSee enabled Wi-Fi router.
2)
"WiSee technology uses multiple antennas to focus on one user to detect the person's gesture."
There is no way to track a person.
Depends what you mean by doesn't work. In both IE and Chrome I can see the video window, I can click on the play button and then all I see is the swirly animated gif that looks as though the video is being downloaded but it never arrives.
Or don't you see anything at all ?
Try "CS doctoral candidate builds phased array doppler radar capable of tracking and identifying small movements of multiple targets from consumer-grade electronics already widely available in homes, for consumer use". That's rather a different story, and merits attention, even if (like me) you have no personal interest in gesture control of home appliances. (If I wanted to control my entertainment system by waving my hands about, I'd be an orchestra conductor.)
It reminds me of passive radar, in that it uses the interractions of an object with radio waves of other systems.
Personally, I feel a bit of a knob interacting with tech by waving my arms and speaking loudly and clearly to it..... It's all a bit like ordering food at a restaurant when away on holiday. What is wrong with keyboard shortcuts?
Is this an effort to replace inertial sensors? They already do this and do it well. Plus, they do not rely on outside signals to work. There might be a problem in microgravity environments, but if you happen to be in one of those, perhaps you should fork over the cash to have a Microsoft Connect brought up.
