A sports electronic training system with sport ball, and applications thereof, are disclosed. In an embodiment, the system comprises at least one monitor and an electronic processing device for receiving data from the at least one monitor and providing feedback to an individual based on the received data. The monitor can be a motion monitor that measures an individual's performance such as, for example, speed, pace and distance for a runner. Other monitors might include a heart rate monitor, a temperature monitor, an altimeter, et cetera. In an embodiment, a sport ball that includes a motion monitor for monitoring motion of the sport ball stores an identification value received when a shoe that includes a motion monitor contacts the sport ball. The stored identification value serves as a record of the contact.

An easy-to-use and user-friendly apparatus disclosed herein displays motivation for exercise to a user to allow the user to continue comfortably exercise. An audio signal output processor 31 reproduces audio data and a music sound is thus emitted from a loudspeaker 32. The user practices exercise, such as walking or jogging, in synchronization with the tempo of the music sound. At the start of exercise, an exercise information analyzer 23 calculates an amount of exercise of the user based on personal profile information relating to the body of the user, including the body weight, the body height, age and sex of the user received via a keyboard 41, and characteristic information, such as play time and tempo of reproduced music data acquired via a communication I/F 61 and a controller 10. The controller 10 outputs the amount of exercise to a display 34 to notify the user of the amount of exercise.

An exercise assistant system and method for managing an exercise pattern in conjunction with music is provided. The exercise assistant system builds a reference exercise schedule on the basis of user information; designates at least one music file for the reference exercise schedule; stores the reference exercise schedule and the music file; outputs guidance information and the music file in sound on the basis of the reference exercise schedule; displays a reference exercise pattern and an actual exercise pattern in a form of graph; and resets the reference exercise schedule and the music file on the basis of a biological change of the user during exercise. The exercise assistant system and method enables adjustment of the exercise amount and level according to the user's exercise achievement and physical variation during the exercise, such that it is possible to effectively assist the user's exercise. Also, in the exercise assistant system, the music files are selected automatically on the basis of the predetermined designated conditions making possible user enjoyment of the music in various sequences.

In a replay mode control device, the replay mode in reproducing music or video contents is controlled so as to be suitable for a user. A headphone 15 of a mobile music reproducing device 10 is provided with a vibration sensor 12 for detecting movements of the user in the up-and-down direction. A walking movement detection unit 13 detects the walking interval of the user based on an output of the vibration sensor 12. A replay mode controller 14 manages control to adjust the replay rate of music contents to the walking interval of the user.

A CRT display (17) displays a bicycle image (171), a travel path image (172) and obstacle images (173, 175) so that an exerciser works a pedal assembly (4) of an exercise bicycle (1) to take exercise while viewing the display. The travel path image is backwardly moved in a travel direction following rotation of the pedal assembly, while the bicycle image is moved to the left or right to avoid the obstacle image in response to a command from the left or right switches (12,14). A physiological condition detector (80) detects physiological condition of the exerciser to increase resistance against the rotation of the pedal assembly through a load (70) if the exerciser has enough physical strength against the load, while reducing the resistance force if the exerciser cannot stand the load. Thus, the exerciser can take exercise while playing a video game through the CRT display, with an appropriate load being applied in response to his physiological condition.

Structural systems and method are employed including a multiplicity of computers to control the acquisition and enhancement of skilled performance or behavior. Pre-processing computers (8 and 24) each accept signals from any corresponding one of a variety of physiological or other signal transducers either in close proximity to the computer or transmitted to the computer via a telemetering system. The pre-processing computer calculates a number of different measures of this signal and makes the results known to one or more other computers. These other or auxiliary computers control presentation of a display of the data for a human observer, and perform additional calculations which determine if the processed data is within a predetermined range. This range may be a function of time and/or other variables. A measure of the error between the allowed range and the processed data is computed within these auxiliary computers. These results may be used to alter the display. They are also returned to the pre-processing computer where they may alter the pre-processing calculations. Alteration of the display and the pre-processing calculations are adapted to improve skilled performance and behavior without the intervention of a human operator other than the user.
