Method and system for waking up a device due to motion

摘要

A method comprises determining an idle sample value for a dominant axis of a device in an idle state. The method further comprises registering a motion of the device, and evaluating the motion. The method further comprises waking up the device when the analysis of the motion indicates a change in the dominant axis of the device and/or a level of acceleration beyond a threshold.

1. A method comprising:
receiving motion data from a motion sensor in a device, the motion sensor sensing motion along three axes; verifying whether the motion data includes one or more glitches and removing the one or more glitches from the motion data; determining an idle sample value for a dominant axis of the device, the dominant axis defined as the axis with a largest effect from gravity among the three axes, the idle sample value comprising an average of accelerations over a sample period along the dominant axis recorded when the device goes to idle mode after a period of inactivity; registering a motion of the device based on the motion data from the motion sensor; determining whether the motion caused a change in the dominant axis; and waking up the device when the motion of the device indicates the change in the dominant axis of the device, the dominant axis being the axis with the largest effect from gravity among the three axes.
