Abstract: The present disclosure relates to methods and systems of determining swimming metrics of a user during a swimming session. The method can include receiving, by a processor circuit of a user device, motion information from one or more motion sensors of the user device; determining, by the processor circuit using the motion information, a first set of rotational data of the user device, wherein the first set of rotational data is expressed in a first frame of reference; converting, by the processor circuit, the first set of rotational data into a second set of rotational data, wherein the second set of rotational data is expressed in a second frame of reference; determining, by the processor circuit, one or more swimming metrics of the user; and outputting the one or more swimming metrics.

Abstract: Systems and methods of analyzing a user's motion during a swimming session are described. One or more motions sensors can collect motion data of the user. A processor circuit can make motion analysis based on the motion data. The processor circuit can determine if the user's arm swing is a genuine swim stroke. The processor circuit can also determine whether the user is swimming or turning. The processor circuit can also classify the user's swim stroke style. The processor circuit can also determine the user's swim stroke phase. The processor circuit can also determine the user's stroke orbit consistency.

Abstract: Systems, methods, and computer-readable media for enabling efficient control of a media application at a media electronic device by a user electronic device are provided. For example, a user control data request may be generated by a device application of the media electronic device based on a media control data request received from the media application, where the user control data request may be utilized by a controller application of the user electronic device to update the status of one or more components of the user electronic device and/or to communicate user control data back to the device application, whereby such user control data may be utilized by the device application to generate corresponding media control data for use by the media application (e.g., to control game play of a video game).

Abstract: An electronic device may include a motion sensor for detecting movement of the electronic device. Applications that run on the electronic device such as fitness applications or activity logging applications may use motion sensor data to track a user's physical activity. To avoid mischaracterizing a user's movement, motion sensor circuitry in the electronic device may supplement motion sensor data with additional information in instances where motion sensor data alone may be insufficient to distinguish between different types of physical activity. For example, information on a user's speed may be synthesized with motion sensor data to help characterize a user's movement. Information on a user's speed may be determined based on location information. The location information may, for example, be gathered using IEEE 802.11 transceiver circuitry or, in more rural areas, may be gathered using Global Positioning System receiver circuitry.
