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.

Methods for improving simulation of a sporting event by using real-world data are provided. In one aspect, a method includes receiving player positional data and ball positional data. The player positional data includes an identification of a player, orientation of the player on a field, position of the player on the field, and a time the player positional data was captured. The ball positional data includes a location of the ball on the field, and a time the ball positional data was captured. A simulated player and a simulated ball are positioned on a simulated field corresponding to the field, based on the received data. The simulation is run and accordingly modified based on user input. Systems and machine-readable media are also provided.

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.

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.

A mobile terminal and an operation method are provided. The operation method of a mobile terminal includes executing a sport application, obtaining at least one of exercise information and location information on a user from a wearable device, and providing a game result or setting a team strategy of a game that the user performs on the basis of the obtained at least one of exercise information and location information.

A wearable device has a core contraction sensor and a movement sensor which transmits signals to a processor which analyzes the signals and uses the data to control aspects of a video game. The core contraction signal may determine if the user's core is contracted or relaxed. A video game may be used with the wearable device to encourage usage of the core muscles with the player getting points or rewards for engaging their core muscles and properly timing the engagement of the core muscles with body movements. The wearable device may be used in place of, or together with conventional video game control devices. Developing the habit of using the core muscles during may be beneficial in back pain rehab and prevention, fitness training and wellness, athletic performance improvement, and reducing workplace injuries in occupations involving heavy lifting.

Systems and methods for providing a Digital Health Platform (DHP) game for execution on a computing device. The methods comprise: running code on the computing device to facilitate lower extremity tracking in a low light condition and the provision of the DHP game having a virtual environment in which a person is to interact with at least one virtual object; using the code to obtain tracked data defining tracked movements of at least the person's lower extremities as the person plays the DHP game in the low light condition; increasing an accuracy of at least position data contained in the tracked data by performing coarse filtering operations and fine filtering operations using the position data; and recreating the person's lower extremity movement in the virtual environment using the position data which has been coarse and fine filtered.

A game delivery device and so on are implemented which enable an operable object to be operated with increased ease, in the case where game images designed to be executed in a dedicated game device are delivered to a terminal. The game delivery device includes execution means for executing a plurality of game programs designed to be executed in a dedicated game device in accordance with operation information; game program selection means for selecting one of the game programs on the basis of a selection instruction from a terminal; delivery means for delivering, to the terminal, image information based on execution of the selected game program; play mode acquisition means for acquiring a play mode selection instruction indicating whether the selected game program is to be played in a normal mode or an auxiliary mode; and auxiliary means for, when the auxiliary mode is selected, providing an auxiliary function that makes an operation of an operable object of the selected game program easier than the operation of the operable object designed to be performed in the dedicated game device.

A load sensing device for use with an exercise band is disclosed. The load sensing device comprises a band of resilient material, a load sensor attached to the band and configured to measure an extension force applied to the band, and an electronic circuit configured to measure the applied extension force and to wirelessly transmit a signal representative of the applied extension force to a receiver. The band of resilient material protects the load sensor and the electronic circuit from damage by at least partially surrounding them.
