Abstract: Ear buds may have sensors to gather orientation information such as accelerometer measurements during user movements. A host electronic device may communicate wirelessly with the ear buds and may form part of an ear bud system that supplies the user with coaching and feedback while evaluating user performance of a head movement routine or other exercise routine. During operation, the ear buds may gather accelerometer data in a first reference frame such as a reference frame associated with the ear buds and may use a rotation matrix to rotate the data in the first reference frame into a second reference frame such as a neutral reference frame with a fixed orientation to the earth. The data in the neutral reference frame may be analyzed using a user head pose look-up table to categorize measured user head positions as corresponding to respective user head poses.

Abstract: Methods and systems for improving signal reception and call quality by detecting a user's handedness of holding a mobile device during a call are described. Motion data of the mobile device can be collected by one or more motion sensor. A screen tilt angle can be determined and compared with a threshold tilt angle. A screen swivel angle can be determined and compared with a threshold swivel angle. A call handedness can be determined based on the screen swivel angle. One or more parameters of an antenna can be adjusted based on the call handedness.
