Abstract
An NUI system to provide user input to a computer system. The NUI system includes a logic machine and an instruction-storage machine. The instruction-storage machine holds instructions that, when executed by the logic machine, cause the logic machine to detect an engagement gesture from a human subject or to compute an engagement metric reflecting the degree of the subject's engagement. The instructions also cause the logic machine to direct gesture-based user input from the subject to the computer system as soon as the engagement gesture is detected or the engagement metric exceeds a threshold.
