Sophisticated software algorithms interpret those reflections in such a way that the system can judge the distance of-and distinguish between-various objects and, say, discern someone's hands.īecause it relies strictly on the reflection of the light from the camera, it doesn't need ambient light to work, allowing ZCam to function in a dark room, or with any kind of background, bright, dark or otherwise.
The ZCam works by emitting short infrared pulses and then measuring the reflections off objects. In light of the tremendous success of Nintendo's motion-sensitive Wiimote controller for its Wii video game console, 3DV is banking on making a lot of money with technology it thinks can move the genre forward even further. That's because its new ZCam, a 3D camera that plugs directly into a PC, is designed to let gamers' hands be the only controllers they need. If an Israeli company called 3DV Systems has its way, you won't have to just imagine it, or many other examples of games that users could control entirely with their hands, for much longer. Or think about sparring with a virtual boxing opponent by doing nothing but standing up and throwing punches in the air. Imagine playing a flight simulation video game that lets you guide the aircraft with your hands alone.
