Using a miniature camera and a specialized deep neural network, researchers at Cornell
The device, which the scientists called BodyTrak,it only takes one camera directed at the human body to build a complex model that describes movements. The developers note that the camera is not dangerous to others, since the system records and transmits to AI only images of a small part of the body of the person himself.
The secret device is not only in a cell the size ofa coin on the wrist, but also in a customizable deep neural network, the developers explain. It reads elementary camera images or "silhouettes" of the user's body in motion and virtually recreates 14 body poses in 3D and in real time.
The model accurately fills and completes the partial images captured by the camera.

The researchers believe that the development will come in handyfor applications of virtual and augmented reality, as well as monitoring of physical activity in medical and sports applications, where measurement accuracy is critical.
