3D gestures

In search of inexpensive and reliable ways of tracking gestures, the staff of the laboratory of computer science and artificial intelligence of the Massachusetts Technological University Robert Van and Jovan Popovich asked themselves a question - why paint the hands of a computer in different colors (or even better, gloves)? And do it in such a way that the computer can distinguish between different parts of the hand, and distinguish the hand from other objects. The glove is divided into twenty sections, which are painted in ten different colors. An ordinary webcam “watches” the movement of color spots in space.

The computer hand repeats the gestures of the operator with a relatively short time delay. The official launch of the technology has not yet been reported, but the prototype works quite vigorously, as can be clearly seen on the video .
