Optical Touch System for Use with Windows 7 Demo'ed by Quanta

Quanta Computer is demonstrating a slightly different use of the Multi-touch system of Windows 7 than others in the field. Instead of using the the normal touch screen technology, however they're developing a touch display that utilizes twin cameras mounted on the corners at the top of the screen.

Somewhat uniquely, however, Quanta is ditching the usual capacitive and resistive touch panels in favor of its new Optical Touch system, which simply uses two cameras placed at the top corners of the screen. That, Quanta says, still lets you perform all the usual multi-touch gestures in the same manner and, depending on the size of the display, could be significantly cheaper than a traditional touchscreen. Details on any actual products using the technology are expectedly a bit light at the moment, but Quanta says it plans to start mass production "soon," with some releases presumably planned to coincide with Windows 7's debut.

so you just make the motion with your fingers somewhere in front of the screen and it acts like a touchscreen? Cool!

This is neat. I just wish I could use it on my antiquated laptop.



On a side note however, Windows 7 (Pre Beta Build 6801) is really cool.

That's what you say until you see the exaggerated gestures you would have to do. You'd look like a composer or something. If the gestures aren't exaggerated, it would be annoying to have them trigger every time you shift about at the desk. Then again, maybe theres a small threshold for being close to the screen. But with laptop keyboards, you're so close to the screen already.

My guess is that in the final version you'll have to do a good deal of set up for it to function properly and since the input from both cameras to be coordinated for function it should rule out triggering from just typing on your laptop. However, as to how grandiose the gestures would need to be or how close or far from the screen I obviously can't claim to know anything about it. My guess however would be that like the other touchscreens you'll have to actually touch the screen or at least be very close to it for the cameras to properly register.
