DiscoBand Depth-Sensing Smartwatch for Hand, Body Tracking

This is the DiscoBand: a smart wearable device with sensors that operate close to the skin for hand, body and environment tracking. This thin sensing strap is about 1cm in thickness. Carnegie Mellon University researchers Nathan Devrio and Chris Harrison used 8 distributed depth sensors to image the hand from different viewpoints and create a 3D point cloud.

8 other depth sensors were used to track the user’s body and surroundings. Each depth sensor captures a 8×8 depth image. This smartwatch can capture hand poses. It can be used for pose prediction for bimanual activities with only one tracked arm or ad hoc touch tracking.
