US 2025/0093642 A1 · Electronic Device with a Motion Sensor

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.

Dependent claims

An electronic device comprising:

one or more motion sensors;
one or more processors;
and
memory storing instructions configured to be executed by the one or more processors, the instructions for:
setting a reference orientation to a first baseline;
obtaining, from the one or more motion sensors, motion data representative of a motion of the electronic device;
and
in accordance with a determination that the motion defined relative to the reference orientation satisfies a criterion, resetting the reference orientation to a second baseline.
