Abstract
A wearable audio device is provided. The wearable audio device includes a sensor, such as an IMU and a controller. The sensor is configured to capture rotational motion data. At least a portion of the captured rotational motion data corresponds to head motion of a user. The sensor is further configured to generate a sensor orientation of the sensor based on the rotational motion data. The controller is configured to (1) receive the rotational motion data and the sensor orientation from the sensor; (2) generate, based on the rotational motion data, an orientation calibration parameter; and (3) map the sensor orientation to a head orientation of the user based on the orientation calibration parameter.

A wearable audio device, comprising:
- a sensor configured to capture rotational motion data corresponding to head motion of a user;
- and
- a controller comprising a processor and memory storing instructions that, when executed, cause the controller to:
- receive the rotational motion data from the sensor;
- process the rotational motion data using at least one trained neural network model;
- generate, based on output of the at least one trained neural network model, an orientation calibration parameter;
- and
- map a sensor orientation of the sensor to a head orientation of the user based on the orientation calibration parameter.
A method for automatically calibrating a sensor orientation of a sensor of a wearable audio device, comprising:
- capturing, via the sensor, rotational motion data, wherein at least a portion of the rotational motion data corresponds to head motion of a user;
- processing the rotational motion data using at least one trained neural network model;
- generating, based on output of the trained neural network model, an orientation calibration parameter;
- and
- mapping the sensor orientation of the sensor to a head orientation of the user based on the orientation calibration parameter.
