Systems and techniques for the collection and display of athletic information. Athletic data relating to a single person or group of people is collected at a central location, and subsequently displayed at a desired remote location so that the person or people can review and critique their performance. In addition, athletic data for multiple persons can be collected at a central location, and subsequently displayed to a user at a desired remote location, so that the user can compare his or her athletic activities to others.

Exemplary embodiments of the present disclosure are directed to various components of a system for monitoring and/or tracking a user's performance during an activity involving an instrument that is swung. Exemplary embodiments can include a sensor module configured to be secured to the instrument. The sensor module can detect a swing event and/or an impact between the instrument and an object and can implement power management features to limit or manage a power consumption of the sensor module. The sensor module can transmit swing information to an electronic device associated with the user, which can display the swing information, process the swing information, and/or transmit the swing information to a remote system.

A system for providing a user-selectable virtual exercise place. The user exercises while sharing the display of a selected virtual exercise place with another user. The system has an image information database which stores location-based image data related to a virtual exercise place; and an image data controller which selects from the image information database the location-based image data related to the virtual exercise place (hereinafter referred to as “exercise place image data”) received from a first terminal, transmits the selected exercise place image data to the first terminal, displays on the first terminal the exercise place image data corresponding to an exercise start location received from the first terminal, receives movement distance information calculated by a first fitness equipment and displays on the first terminal the exercise place image data corresponding to the location moved by the exercise distance from the exercise start location.

A golf aid system for assisting a user with a golf shot on a golf course includes a user tracking system configured to determine the location of the user on the golf course, a portable electronic device with a display screen, and a processor. The processor, which is operable to communicate with the user tracking system and the portable electronic device, is configured to determine one or more target locations on the golf course, with each of the target locations representing a recommended target for a respective one of the golf clubs. The processor directs the portable electronic device to display an indicator of the respective golf club proximate the corresponding target location via the display screen, such that the user perceives at least a portion of the indicator to be coincident with the corresponding one of the target locations.

A three-dimensional golf ball marker for marking a position of a golf ball on a putting green includes a housing with a bottom surface and a spherical cap including a texture selected from the group consisting of golf ball like dimples, smooth, grooved, ridged, rubbery, and polished. The spherical outer surface of the housing may rotate and includes an alignment mark formed around at least part of a diameter of the housing. The three-dimensional golf ball marker may include a removable marking disc, with an alignment mark formed on at least one side, which is retained adjacent the bottom surface of the housing by a magnet or retained within a slot. The three-dimensional golf ball marker may include a wireless location device that transmits a wireless signal to allow a tracking device to determine a location of the three-dimensional golf ball marker and to generate information of the golfer.

A system configured to be coupled with a participant of an activity. The system comprises: a participant activity monitoring unit configured for monitoring a performance of the activity by the participant; an activity information module configured for storing performance information corresponding to the activity; and a participant performance correlator configured for delivering comparative performance data based on the monitored performance of the activity by the participant and the stored performance information.

A virtual exercise place selected by a user is displayed and the user can exercise while sharing the display of the selected virtual exercise place with another user in real time or at a different time. The system has an image information database in which location-based image data related to a virtual exercise place is stored; and an image data controller selecting from the image information database location-based image data related to a virtual exercise place received from the terminal and providing the selected location-based image data to the terminal, displaying on the terminal an exercise place image data corresponding to an exercise start location received from the terminal, receiving exercise distance information calculated by the fitness equipment, and displaying on the terminal an exercise place image data corresponding to a location moved by the exercise distance from the exercise start location.

In one aspect, a swim system may include a reverse thrust system worn by a swimmer proximate the frontal upper torso. The system provides a variable amount of reverse thrust such that the user can swim-in-place or make gradual forward progress. Importantly, this may enable a user to effectively “extend” a small residential pool to serve the same function as a twenty-five meter pool typically found at commercial or government facilities. The system also provides laminar current under the user while swimming, which solves the problems of “leg drop,” the need to “out-kick” the arm stroke, and turbulence and wave action around the head associated with conventional swim-in-place devices. Still further, in certain embodiments the system provides a relatively strong current in the region of the arm stroke moving away from the swimmer which provides enhanced “resistance” for proficient swimmers.
