Power Management
To save power when the system is idle, the SDK supports two modes of operation: performance-mode and battery-mode. In the performance mode, the maximal frame-rate of the camera is utilized and the best tracking algorithms is applied, to ensure the best quality of the tracking data. In the battery mode, the camera frame rate drops significantly and only minimal computational resources is used, to save power. The hand module allows to switch to the battery mode only if no hand-like object is detected for a period of time (inactivity interval). As soon as a hand is seen in the field of view, the performance mode is applied and tracking resumes. Switching from the battery to the performance mode is fast, so even quick hand motions can be detected successfully.
See PowerState interface for more details on controlling the power states and setting inactivity interval
