Physicists build laser tweezers controlled with Kinect
November 5, 2012
Now anybody can pick up and move micron-scale particles using their hands and arms thanks to a Kinect-controlled infrared holographic laser device called HoloHands. The interface allows user to “pick up” and “push” particles they see on a computer screen using hand, arm and body movements alone, Technology Review Physics arXiv Blog reports.
The system shows users the field of view in which the tweezers operate. A wave of the hand creates a trapping region, which holds particles. This can then be picked up and moved with further arms movements.
It may also be possible to build stuff by hand using a Lego-like set up where students make microscale devices and machines using HoloHands.
