The ZCam

Zcam (Gizmodo Article)

The ZCam from 3DV Systems is the first consumer low-cost camera that can capture depth information or in other words, 3d space. It's like the Wiimote except no extra peripherals are needed, just your hands and body. In a demonstration at GDC this past week, a guy went through a piece of software almost identical to the one from Minority Report using hand motions to go through different folders and move his way around. "It gets 3D information by emitting pulses of infra-red light to all objects in the scene and sensing the reflected light from the surface of each object." It can detect 3d motion and volume down to 0.4 inches with full color 1.3 megapixel video at 60 frames per second. There won't be any lag if it is used in applications like video games or training programs. Not sure on when it's going to be released, but I can't wait to see what companies will do with this.
