US Patent 10481700 Frame rate setting for power efficient gesture detection

Methods, systems, and devices for gesture detection are described. A device may identify a set of configured gestures and determine a set of minimum frame rates, where each minimum frame rate may correspond to at least one configured gesture in the set of configured gestures. The device may set an initial frame rate for a sensor based at least in part on the set of minimum frame rates. For example, the device may identify a maximum frame rate of the set of minimum frame rates and set the initial frame rate to be equal to or greater than the maximum frame rate. The device may capture a set of images using an initial frame rate and detect a configured gesture of the set of configured gestures based on the set of images.
