A system and method for analyzing and improving the performance of a body motion of an animal or human subject requires instrumenting a subject with inertial sensors, monitoring a body motion of interest, converting sensor data into motion data and animation, comparing the motion data with existing data for motion related performance parameters, providing a real-time, information rich, animation and data display of the results in color coded displays; and based on the results prescribing a training regime with exercises selected from a library of standardized exercises using standardized tools and training aids.

An embodiment is an avatar or avatar environment to visualize data within an athletic performance system or service and/or a social network system or service, for example as part of the Internet. The avatar may further evolve or alter its appearance, animation, or other visual or audio characteristics in response to the data or other input. In particular, the avatar of an embodiment may respond to and provide visualization of athletic or sport performance data. According to one or more aspects, an avatar may be placed on other network sites and updated based on athletic performance data. The avatar may be awarded for goals achieved by a user. The awards or gifts may further include non-avatar related items such as apparel, gift cards and the like.

Dynamic tracking of user-based activity is provided as a function of information received from a plurality of data sources. Tracking of user activity information via a first application occurs correlated to steps taken by a user over a period of time. A health score associated with the user is presented in a GUI. Further, communication with a second application occurs during gameplay. Moreover, the at least one computing device is configured to combine, using the first application, the tracked user activity information with at least a portion of the user interaction information into an activity value. The computing device updates the health score using the activity value. Still further, the computing device is configured to store the updated health score in association with a record concerning the user, and to cause a notification on the mobile computing device of the updated health score when the first application is not executing.

Apparatus for use in a game of tag (or variations of this, e.g. a variation of manhunt) that determines the length of period a player is Tag (or a value dependent upon this length) for each of a plurality of such periods, preferably aggregating these periods (or values) for players and/or for teams and displaying results centrally and using touch-sensitive means to detect touching, and a corresponding computer game. The touch-sensitive means may comprise sensing and indicating means carried by one player to sense and indicate a first touching of that player and to sense a next touching by that player of another player (which two touchings define a period of Tag of said one player) by cooperation with similar means carried by that other player, which means may comprise a signal generator, generating a different signal while a player is Tag.

In some aspects, a system is provided that includes (1) a plurality of mobile devices; and (2) an application on each mobile device, the application adapted to (a) allow exercisers to form an exercise group; (b) track position or change in position of each exerciser in the exerciser group; and (c) display an avatar having a position that is controlled by a position or change in position of one or more member of the exercise group. Numerous other aspects are provided.

In some aspects, a system is provided that includes a plurality of mobile devices and an application on at least a first mobile device. The application is adapted to track position information regarding the first mobile device, communicate the position information to a web server, receive position information from the web server regarding other mobile devices within a predetermined distance of the first mobile device, and use the position information regarding the other mobile devices to affect one or more characteristics of a video game executed on the first mobile device. Numerous other aspects are provided.

Sports simulations may include sports nodes providing a user interface for players to participate in a sports simulation. A user interface for a player to interact with a sports service may be hosted on a computing device. The sports service providing the sports simulation game may be hosted on a server. The user at the user interface of the computing device may interact with the sports service via a network and/or the Internet. Multiple players may interact on their computing devices with the sports service. The multiple players may interact in one simulation, or may interact in multiple simulations, or may each interact with the sports service in solo simulations. Players may be matched in pairs where each pair plays a simulation to determine a winner.
