Apparatus, systems, and methods for monitoring the performance of an individual during a fitness activity are disclosed. A method of monitoring the performance of a participant engaged in a fitness activity includes receiving a GPS signal during the fitness activity at a portable fitness device used by the participant; determining participant performance data based on the received GPS signal; at a stationary position beacon, transmitting location data associated with the location of the stationary position beacon; at a mobile participant receiver supported by the participant, receiving the location data from the stationary position beacon; and modifying the participant performance data based on the data received from the stationary position beacon.

A method for calculating distance information according to the present invention includes: acquiring a current location; reading out map information of a golf course corresponding to the current location; calculating a horizontal distance to a target of the golf course from the current location by using the map information; calculating two first direction intersection where a straight line in a first direction, connecting the current location and the target, and a green boundary line of the golf course meet; calculating two second direction intersection where a straight line, which is perpendicular to the first direction and passes through the target, and the green boundary line meet; and calculating edge distances between the target and the two first direction intersection and between the target and the two second direction intersection.

A sports and performance media positional detection system, comprising: at least two elements, with at least one element involved in the sporting activity; a power source; and machine-to-machine communication, which are collectively arranged such that if any two or more elements interact, their electromagnetic properties can be detected thus allowing the position of the interacting elements to be communicated to a decision maker. The system can be applied to at least one stationary element, which can be the playing surface, lines defining the boundaries, or a set of goalposts; and at least one moving element, which could be a ball, footwear, or the participants themselves. The system can also be applied to performance media capture.

A system for providing golf information, the system which includes a green photographing unit for photographing an image of an area including a green on a golf course and communicatively connected to a communication network to transmit green image data to an outside, a golfer terminal that is carried by a golfer on the golf course and communicatively connected to a communication network to transmit golfer position data to the outside, and an information providing server that is communicatively connected to the communication network to generate golf information using the green image data and the golfer position data and transmit the generated golf information to the golfer terminal.

A system includes a minimally intrusive display system (MIDS) configured to be disposed on an eyewear. The MIDS includes a display system and a sensor system configured to provide for a sensor data. The MIDS further includes a processor configured to process the sensor data to derive an activity metric. The processor is further configured to display, via the display system, the activity metric, wherein the display system is disposed in the eyewear so that the activity metric is only viewed when a user of the eyewear turns the user's pupil towards the display system at angle α from a forward direction.

Provided is a highly reliable, cost-effective scattered object collection system that can determine the correct position of each scattered object on the ground, such as a ball, and efficiently collect scattered objects by reducing unnecessary traveling of an autonomous collector. The scattered object collection system includes an autonomous collector that performs a collecting operation by picking up balls B while traveling in a work area W and a collector management unit that manages the autonomous collector. The collector management unit acquires positional information on the autonomous collector, identifies an actual position where each ball B was picked up in the work area W using the acquired positional information, and allows the autonomous collector to perform a collecting operation in a place having a high density of balls B with higher priority than a place having a low density of balls B using the identified actual positional information on each ball B.

A system for data collection during a game includes a positioning system for determining various locations of a user during the game, a tag reader for reading a passive RFID tag held in close proximity to the tag reader, and a processor for correlating the location of the user with the time at which a tag is read to enable action locations for the game to be determined.

Systems and methods track a first object when continuous tracking information for the first object is not available. The systems and methods detect when the tracking information for the first object is not available. A last time of a last determined location of the first object is determined and a second object closest to the last determined location at the last time is determined. The location of the first object is associated with a location of the second object if tracking information for the first object is not available.

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.

Generating user preference activity maps is disclosed, including: collecting a plurality of user activities recorded by a plurality of GPS recording devices; and aggregating the plurality of user activities to a base map to generate a user preference map.
