Automatic switching between different modes of tracking user motions to control computer applications

摘要

Automatically switching between different modes of using user motions to control applications running in a computing device. For example, the computing device communicates with devices attached to portions of a user (e.g., arm, hand) respectively to receive motion-based measurement data. One of the devices is attached to a portion of the user (e.g., hand) and capable of tracking six independent motions of the portion of the user. The computing device can generate input controls for one or more applications running therein using measurements based on the six independent motions in a first mode, and using measurements based on three of the six independent motions in a second mode. Based on an indication derived from inputs, or the lack of inputs, from some of the devices attached to the portions of the user, the computing device can automatically switch between the first and second modes.
