Microvision Inc., a small Redmond, Washington, company, was at the CTIA Wireless industry show this week to demonstrate a prototype of its projector. It's about the size of two full-size iPods, but by the time it goes on sale later this year, it should be about 30 percent smaller, said Russell Hannigan, the company's director of projector product management.
In a darkened room, the prototype beamed out surprisingly bright, crisp and large video from a connected iPod Nano: With the projector held 6 feet (1.83 meters) away from the wall, the image measured 6 feet (1.83 meters) diagonally and was as sharp as a DVD.
On the brightly lit showroom floor, the image was less impressive, but projected on a piece of paper held a foot away, it still made for a nice alternative to the iPod Nano's screen, which is slightly larger than a stamp.
The technology differs substantially from standard projectors: Microvision's unit shines red, green and blue lasers on a rapidly moving, 1-millimeter square mirror, which ''paints'' the picture line by line, so fast that it blends into one image.
