Kinect sensors used for superaccurate twohanded gesture control

first_imgEven before Microsoft embraced homebrew development for its Kinect motion controller, the device was being put to good use outside of controlling Xbox 360 games. But in most cases only a single Kinect sensor has been used in projects. 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.3Gear believes its gesture control system has many potential uses including for gaming, 3D medical imaging, 3D computer aided design, and as a way of creating in 3D ready for 3D printing. And they aren’t afraid to share, either. The SDK has been released into public beta for free to allow it to be incorporated into applications.In order for the system to work you need two Kinect sensors, an aluminum frame, and 2 wall mounts. To run the free SDK will require quite a powerful rig with the recommended spec being a Core i7 2.3GHz, 8GB RAM, and a 64-bit copy of Windows 7. OS X and Linux ports are under consideration, but only if 3Gear see enough interest for them to spend time doing the work.Getting setup to play with the system is going to be relatively cheap to do, and therefore it’s likely game development teams and CAD software companies may experiment with it. I also think there’s potential for the 3Gear system to enhance a head-mounted system such as Project Glass or Oculus Rift, but that would require reducing the size of the Kinect motion sensors considerably to allow them to also be head mounted.Read more at 3Gear Systems Blog, via GamesBeatlast_img
