Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
Nice, although there's a slight delay in reaction to the hand gesture.
"Slight" delay?
That is an ok proof of concept, but to be usable the response time - and I would guess the accuracy - has to be greatly improved. Now it is but a flashy showpiece.
I reckon it's a form of sonar or something.
However, even though items like the Wii incorporate the third axis very well, I would think it would be a little inconvenient when operating a computer; not to just have windows all over the place, but windows in the distance as well.
coochi coochi coo ... haha
think about it.
They could use this technology in the next gen wii!
I also reckon it is either some form of Radar, or an array of some form using IR and it detects whether the beam is broken.
The idea is good in principal, but I can't see it ever really replacing the mouse on a PC, or a touch screen for larger scale uses.
*Waits for ThriXXX to implement this in their software*
Could be done using two cameras and motion tracking.
*Awaits the inevitable new wave of interactive porn*
I think it's done with sound/echo or something like that...
cool! now i can finally touch those boobs!
Radar and echolocation couldn't resolve something that pointed and small without also looking at the entire hand, and it's clear that the "dot" is only his fingertip.
I'd guess that it's a simple Infra-Red camera again, hidden behind some semi-reflective material that it can easily see through. Setup your software to see only the closest point and you're set. There's probably an IR emitter as well in there.
Simple.
yeah, i saw this in the mitsubishi(?) booth at the DC autoshow
i made my own craptastic car with it
I'm guessing it's an ultrasound panel that measures the delay in echo to determine where his finger is.

Isn't this just an extension of Johnnny's projects found at http://www.cs.cmu.edu/~johnny/projects/wii/ ? Maybe it's more sphisticated (though I like Johnny's vid's better ;) )
