Rear-projection may be deader than dead as far as the biggies are concerned, but the folks at nLighten are intent to squeeze a bit more life out of these 72-inch 1080p DLP sets by sticking an infrared camera inside next to the light source that detects cursor points from an IR-tipped pen, allowing for a simple (no multitouch) touchscreen interface. It can act as a standard Windows mouse allowing for 1080p touchscreen Google Earth, or any other app.The 72-inch IR-pen screen is priced at $3,000, and a similar version that uses camera triangulation from cameras mounted on the top of the bezel for actual finger touch control will set you back $4,000. As you can see in the video, the finger-touch seems to be a bit finicky, but the IR pen control is smooth as silk. [CEDIA 2008]
