Microsoft Research recently showed off a Kinect project that allows fine-tuned gesture control. This motion sensing device is now able to read whether your hand is open or closed, bringing mid-air multitouch like what you see in 'Minority Report,' all thanks to a new development of the software.
This level of User Interface was demonstrated by Microsoft Research using Windows 8. Their 'Handgrip' detector moves beyond Kinect's previous recognition of the hand as a single point of the body, overlaying the processing of the hand state on top of this.
Using varied hand states, we see Cem Keskin air-painting and Bing maps being manipulated and zoomed. Could this be a precursor to the interface design we see in the next generation Xbox?
