An electronic device may comprise audio processing circuitry, pace tracking circuitry, and positioning circuitry. The pace tracking circuitry may be operable to selects songs to be processed for playback, and/or control time stretching applied to such songs, by the audio processing circuitry based on position data generated by the positioning circuitry, a desired tempo, and whether the songs are stored locally or network-accessible. The position data may indicate the pace of a runner during a preceding, determined time interval. The pace tracking circuitry may control the song selection and/or time stretching based on a runner profile data stored in memory of the music device. The profile data may include runner's distance-per-stride data. The electronic device may include sensors operable to function as a pedometer. The pace tracking circuitry may update the distance-per-stride data based on the position data and based on data output by the one or more sensors.

Systems and methods for golf analysis including a tag coupled to a golf club providing statistical analytics for coaching including text, tabular, graphic, and image-based outputs that include trends information for the golfer, all based upon actual golf play on course situations, wherein the golfer inputs shot data during play, without interrupting the flow of the game, and uploads the shot data for analytics and review online, and wherein all information related to a given user are reviewable by an authorized coach user through a web-based coach access account. The system is further operable to provide the coach user rights for providing corrective or instructive feedback to the user, including visual recommendations such as modified target areas.

A system that wirelessly integrates actual sports equipment with a computer and the internet to allow players remotely located from one another to play a competitive simulated sports game. An individual player may opt to play solo or practice to improve basic techniques. The system includes motion sensors connected to the player and a motion sensing device, all containing circuits and contact or motion sensors coupled with signal processing and radio frequency transmitter circuitry, thereby wirelessly communicate game performance information to a remote receiver-computer. The computer displays player information and visually simulates and controls a game between two players via the internet, having similar equipment and remotely located from each other. Standard sports equipment may be retrofitted with the sensors and associated circuitry to convert such equipment into “smart equipment” for use with the system. The system employs specially developed computer software to process player performance data, control game play, communicate game information between players, generate and control visual simulations and display player performance information.

Providing real-time segment performance information is disclosed. In some embodiments, a segment associated with a user's current activity is determined based at least in part on at least a portion of location information recorded so far. In some embodiments, real-time segment performance information associated with the user's current activity on the segment is communicated.

A system and method for identifying a person in a geographic area of interest, who shares the identity of friendly participants with a user if certain criteria are met. In one form, the identity of a participant in the area and meeting certain criteria is displayed to a user or other friendly participants. The identity is displayed to friendly participants on, for example, a GPS-equipped cell phone or head-mounted glasses. Other information can be shared among friendly participants, including social information, photographs, gender, status, and location.

A media-playback device includes: a media-output device that plays media content items; a physiological measurement device programmed to measure at least one physiological measurement of a user of the media-output device; and a physiological control engine configured to: identify a current physiological measurement for the user; and cause the media-output device to modify playback of the media content items based upon the current physiological measurement.
