It has been news for awhile, but Microvision is releasing a micro projector based first person shooter video game controller.
The guys at CrunchGear had a first hand test of the Microvision product and seem to be very excited about it for a few different factors.
The first factor they mention is that the projector is based off of Microvision’s SHOWWX pico projector. The projector is modified to create an 848×480 image that always stays in focus. They reiterate that it is always in focus. Further, the pico projector is mounted on to a plastic gun to create the controller. The gun itself is equipped with motion detectors that let you go as far left, right, up or down as you want to go.
The most impressing thing, they mention, is that there is no lag between movement of the gun and video recognition of movement. Impressive new technology!
