Abstract
In a head-mounted device, position and motion sensors may be included to determine the orientation of the head-mounted device. A motion sensor may experience error that accumulates over time, sometimes referred to as drift. To mitigate the effect of drift in a motion sensor, a reference orientation for the motion sensor may be reset when a qualifying motion is detected. The qualifying motion may be detected using one or more criteria such as a total change in angular orientation or rate of change in angular orientation. The reference orientation for the motion sensor may also be reset when a duration of time elapses without a qualifying motion being detected.
