It's no secret that multi-touch support is one of the stand-out features of Windows 7, and it's also no surprise that plenty of companies seem eager to get in on the action, one of the latest which is uber-manufacturer Quanta Computer. 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.
