No one sells these (yet). That particular implementation has a projector below frosted glass, so it's essentially a full table or desk in size. The touch sensing is done with infrared lights going sideways through the glass, and infrared cameras looking at the glass from underneath. When someone touches the glass the internal reflectivity of the glass changes at the touch location, and some infrared light spills out of the glass which the camera detects. In its current incarnation it cannot be used in a well lit room. Apple's method for the iPhone is capacitance based. Microsoft has two different approaches - I believe their table-type version is similar to the video above, and they've recently documented a laptop based version which is essentially an infrared proximity sensor grid placed behind the LCD such that it shines through the plastic and glass of the display, and if anything is near to or touching the display it can be sensed. I suspect that Apple has the correct approach here, though - it's not affected by ambient light, and can be made thinly and cheaply enough to make it practical for displays of all sizes. It's major limitation is that it can't sense gloved fingers nor anything that doesn't change the capacitance. Microsoft's table style version can sense objects placed on the surface - the demonstration they used was a bluetooth camera. When placed on the table, the pictures in the camera showed up on the display and could be manipulated. One could drag and drop photos to and from the camera, and all the details were taken care of by the software. But that's more of a 'neat' thing than something that's necessary - other mechanisms could be used in a similar easy fashion without having the detect the camera on the display device. So, if you want one you'll probably have to make one, or wait. -Adam On 6/25/07, Stef Mientki wrote: > > http://video.google.com/videoplay?docid=3178556272065560729&q=jeff+han+nyu&total=22&start=0&num=10&so=0&type=search&plindex=5 > > cheers, > Stef Mientki > > Kamer van Koophandel - handelsregister 41055629 / Netherlands Chamber of Commerce - trade register 41055629 > > > -- > http://www.piclist.com PIC/SX FAQ & list archive > View/change your membership options at > http://mailman.mit.edu/mailman/listinfo/piclist > -- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Moving in southeast Michigan?
