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.

Systems and methods for determining swimming metrics

A system may have electronic devices with wireless communications circuitry. Devices may transmit short-range wireless signals such as advertising packets. Each advertising packet may contain information on the motion context of the transmitting device. By comparing motion context information for received packets with local motion context information, an electronic device may analyze received signal strength indicator measurements with enhanced accuracy. Presence-in-vehicle state information and/or other device context may also be obtained from nearby devices by comparing local and received motion context.

Electronic devices with motion-based proximity sensing

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.

Systems and methods of swimming analysis

The present disclosure relates to systems and methods of estimating energy expenditure of a user while swimming. A processor circuit of a user device can estimate a speed of the user based on a stroke rate and a stroke length. The processor circuit can estimate an efficiency of the user. The processor circuit can classify a swimming style of the user. The processor circuit can determine energy expenditure of the user based on the speed, the efficiency, and the style. The processor circuit can also detect glides of the user and adjust the energy expenditure.

Systems and methods of swimming calorimetry

Systems, methods, and computer-readable media for managing or classifying movement states of an electronic device are provided that may utilize communications circuitry data from one or more communications circuitries when determining a current or future movement state of an electronic device.

Management of movement states of an electronic device using communications circuitry data

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).
