Abstract:
1. A method comprising: determining, by a processor of a wearable computing device and based on motion data generated by a motion sensor of the wearable computing device, a plurality of motion vectors, wherein one or more components of the wearable computing device are operating in a first power mode during a first time period, and wherein the motion data indicates movement of the wearable computing device during the first time period; determining, by the processor, that a first angle between a first motion vector of the plurality of motion vectors and a second motion vector of the plurality of motion vectors satisfies a first angular threshold, wherein the first motion vector is associated with a first time, wherein the second motion vector is associated with a second time, and wherein the second time is later than the first time; determining, by the processor, that a time difference between the first time and the second time satisfies a threshold amount of time; determining, by the processor, that a second angle between a plane parallel to a display of the wearable computing device and a plane perpendicular to a gravity vector satisfies a second angular threshold; and responsive to determining that the first angle satisfies the first angular threshold, that the time difference satisfies the threshold amount of time, and that the second angle satisfies the second angular threshold, transitioning, by at least one component of the one or more components, from operating in the first power mode to operating in a second power mode, wherein the at least one component consumes more power while operating in the second power mode than while operating in the first power mode.
