Balance measurement systems and methods thereof include at least one measurement device or indicator and an unstable or dynamic device or surface or other balance device. In example forms, the at least one measurement device is generally removably mounted to a portion of the body of a user (and/or to a portion of the balance device) such that the movements and body behavior of a user (and/or the balance device) can be measured as the user attempts to balance on the balance device. According to one example form, the unstable device includes a suspended rope or slackline. According to other example forms, the balance device includes a generally unstable platform.

An exercise and communications system includes an interactive device, a remote device, and an external device, wherein the interactive device is configured to gather data relating to a user of the system and transmit the same to the remote device, and the remote device is configured to provide analyze the data and transmit a response to the interactive device, which in turn communicates the response to the user and additionally communication with an external device for retrieval of instructions, programs, and data, inter alia. An exercise and communications system facilitates communication between a plurality of users, each having an interactive device and a remote device.

A method and system for using a low resolution image of a golfer's swing for analysis is disclosed. Cameras obtain images of various portions of a golfer's swing. A computer calculates parameters associated with a golfer and a golf club from the images. Parameters include body angles, head position, shoulder positions, arm positions, hand positions, leg positions, foot positions, club shaft angles, and club head position. Different portions of the swing are captured using the cameras, including a static initial address, a backswing, a downswing, a forward swing, and a follow-through. A computer uses measured parameters from two or more portions of the swing to determine comparative parameters during different portions of the swing. The computer uses the parameters to generate swing analysis outputs, including swing characteristic information and/or swing profile information. A correlation table relates identified swing analysis outputs to particular recommendations to the golfer to improve the swing.

The present disclosure generally relates to navigating, viewing, and sharing activity and workout data and interacting with workout and/or activity applications. In some examples, scrolling of activity data is based on the content being displayed. In some examples, friends' activity data may be viewed. In some examples, a notification and workout data for a friend's completed workout is received and displayed. In some example, the activity data received from friends is viewed and managed. In some examples, workout data for a multi-segment workout is displayed in a three-dimensional stack on a map. In some examples, a workout application operates in a limited mode until a touch input is received with a characteristic intensity that is greater than a threshold intensity.

Virtual golf system for playing golf, comprising a plurality of trackable golf balls, wherein each golf ball comprises transmitting means for broadcasting electromagnetic beacon signals for detecting a position of the golf ball, a position determination unit comprising three receiving antenna's arranged for receiving beacon signals broadcasted by any of said plurality of trackable golf balls, and wherein said position determination unit is arranged to determine a position of said golf ball on a driving range based on time differences of a broadcasted beacon signal received by said receiving antenna's. A plurality of trackable golf balls and a plurality of players may be active at the same time. Trackable golf balls may be paired with specific players. A game controller advances a virtual game of golf each time a trackable golf ball is stroked by a player.

In one general aspect, an apparatus to monitor movement of an object may include an input device configured to trigger pre-selection of a type of performance of the object, at least one sensor used to measure a motion parameter of the object, a controller configured to receive the motion parameter of the object and compare the measured motion parameter with a motion reference, and an output device configured to display, in real-time, a feedback information based on the comparison.

System and techniques for tracking caloric expenditure using sensor driven fingerprints are described herein. A set of outputs may be obtained from a plurality of sensors. A fingerprint may be generated using the set of outputs. The fingerprint may correspond to an activity observed by the plurality of sensors. The generated fingerprint may be compared to a set of fingerprints stored in a database. Each fingerprint of the set of fingerprints may correspond to a respective caloric expenditure. A caloric expenditure may be calculated for the activity based on the comparison. An exercise profile of a user may be updated using the caloric expenditure

Methods and apparatus for authorizing use of a mat processing device are disclosed. The disclosed process requests and receives a public customer identifier. If the public identifier is not on a “required” list, the process authorizes a mat processing despite payment not yet being confirmed and no private information being. If the public customer identifier is recognized by the system, the process requests and receives a private customer identifier, even though the mat processing has already been authorized. If the private identifier is associated with the public identifier, the customer's account is debited for the mat processing. If the private identifier does not correspond to the public identifier, and optionally an additional user confirmation attempt fails, the public identifier is placed on the “required” list, so subsequent attempts will not receive a “free” mat processing.

An information processing apparatus disclosed has a controller. The controller obtains circumstances information defined as information relating to circumstances around the present location of a user. The controller determines a recommended exercise as a kind of exercise that is suitable for the circumstances around the present location of the user on the basis of the circumstances information obtained. Then, the controller sends suggestion information to a user's terminal used by the user. The suggestion information is information that suggests the user to do the recommended exercise at the present location of the user.

A watch or other type of portable electronic console that employs a number of different functions in order to improve its usability. The watch may, for example, allow a user to connect the watch to one or more remote electronic devices, such as an electronic performance sensor or MP3 player. The watch then displays information related to the connected electronic devices. Still further, the watch may allow a user to control the operation of one or more connected remote electronic devices. Thus, if the watch is connected to a remote speed/distance monitor employing a calibration variable, then the watch may allow the user to adjust the calibration variable.
