Still really cool though.]]>Jan 5th 2010 9:39AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/
maaan, touchscreens were soo 90's]]>Jan 5th 2010 9:50AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/
it don't mean that a touch screen can't be implemented along with this. Touch screen and this technology aren't mutually exclusive.

It looks like a Natal for your phone.

Judging by the video of what the screen sees it looks like its using a infrared TOF(time-of-flight) camera (like Microsoft's Natal), which is why we see a silhouette of a finger. The silhouette is extruded and intersected to form the visual hull approximating of the subject (your finger in this case).]]>Jan 5th 2010 11:50AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/Jan 5th 2010 9:48AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/next step multi-touchless... add that with 3D images (less the eyeglasses)
and I might not be able to tell whats real and not anymore]]>Jan 5th 2010 9:48AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/Jan 5th 2010 9:54AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/
I agree i could see the use for this in CAD designing...

They should have emphasized the used of 3d drawing more. like grab and turn pivot screen.. or something. ]]>Jan 5th 2010 10:03AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/Jan 5th 2010 9:57AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/Jan 5th 2010 10:07AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/Jan 5th 2010 10:14AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/
At the moment, my favourite application of this would be a District 9-esque spacecraft control system.]]>Jan 5th 2010 10:15AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/Jan 5th 2010 10:45AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/ . ]]>Jan 5th 2010 11:09AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/Jan 5th 2010 11:18AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/Jan 5th 2010 11:23AMhttp://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/http://www.engadget.com/2010/01/05/tokyo-universitys-touchless-pointing-system-could-wipe-out-smud/Why does engadget lately do a 'via: site x' and 'source: site y' and then it turns out it's not the source at all but yet another site, who themselves says they got it from a 3rd (or 4th) site.

The source as you mention yourself is the university of tokyo in japan, and the link for that is http://www.k2.t.u-tokyo.ac.jp/vision/index-e.html
