An anonymous reader writes "In most homebrew Kinect projects only a single Kinect sensor has been used. 3Gear Systems decided to use two, and in doing so has created one of the most accurate gesture-based control systems I have ever seen.
3Gear Systems is just three people working out of San Francisco with a desire to use our hands as an interaction system. That means putting your fingers, thumbs, and wrists to good use. But in order to do that you need very accurate tracking and hand posing recognition.
Using Kinect as a starting point made sense due to how cheap the sensors are, but the standard Kinect SDK only really caters to large movements performed with your body. It isn’t well suited to tracking the position of individual fingers or the rotation of a hand. So 3Gear created its own SDK using computer graphic algorithms and combined it with a database of 3D images that define common hand positions. The end result is an incredibly fast two-hand pose detection system that counts lag in the low milliseconds."
