Some of you have probably already seen Google’s April 1st announcement of their technology to use “Motion Sensing” to control Gmail.
I betcha Google probably didn’t think of Kinect when making that spoof or perhaps they did which is why it sound plausible in a remote way.
Anyways the FAST crew have brought responded to the spoof with demoing their Software doing just that. i.e. having motion control for Gmail using a Kinect and custom software of theirs.
Actually this seems very feasible if you could get an intermediary software layer to function as a keyboard by recognizing Kinect Gestures, controlling Gmail is a matter of mapping keyboard shortcuts to gestures. At least that is how I think this works.
