Abstract
A wearable device for detecting a user state is disclosed. The wearable device includes one or more of an accelerometer for measuring an acceleration of a user, a magnetometer for measuring a magnetic field associated with the user's change of orientation, and a gyroscope. The wearable device also includes one or more microphones for receiving audio. The wearable device may determine whether the orientation of the wearable device has changed and may designate or re-designate microphones as primary or secondary microphones.
Claims21
-20. (canceled)
A wearable device comprising:
- a sensor comprising at least one of a magnetometer or an accelerometer, the sensor configured to produce first orientation data;
- a low-power processor configured to:
- obtain first orientation data from the sensor associated with the wearable device;
- and
- identify a suspected user state of a user of the wearable device based on the first orientation data;
- a high-power processor, computational capacity and power consumption of the high-power processor being greater than computational capacity and power consumption of the low-power processor, the high-power processor configured to receive the suspected user state from the low-power processor;
- and
- a long-range communication module connected to the high-power processor and configured to receive the suspected user state from the high-power processor and communicate with a cloud computing system, the cloud computing system configured to:
- receive the first orientation and the suspected user state from the long-range communication module;
- and
- determine whether the suspected user state is an actual user state based on the suspected user state, the first orientation data, and historical user state feature data.
