An interior bike system includes: an interior bike including a rotational angle detection sensor sensing a pedal rotation angular speed; a motion recognition sensor recognizing a head or upper body motion of a player; a heart rate measurement sensor measuring a heart rate of the player; a controller receiving and transferring sensing signals of the rotational angle detection sensor, the motion recognition sensor, and the heart rate measurement sensor to a web server; the web server determining whether performing the task motion given to the player is successful based on the signal of the motion recognition sensor of the controller, and generating a content image to which whether the player succeeds in performing the task motion is reflected and transmitting the generated content image to the content controller; and a display unit displaying an image transmitted from the web server through the controller.

Embodiments described herein relate generally to wearable electronic biosensing garments. In some embodiments, an apparatus comprises a biosensing garment and a plurality of electrical connectors that are mechanically fastened to the biosensing garment. A plurality of printed electrodes is disposed on the biosensing garment, each being electrically coupled, via a corresponding conductive pathway, to a corresponding one of the plurality of electrical connectors. The apparatus can further include an elongate member including a conductive member that is coupled to a plurality of elastic members in a curved pattern and that is configured to change from a first configuration to a second configuration as the elongate member stretches. The change from the first configuration to the second configuration can result in a change of inductance of the conductive member.

Systems and methods for sensing and monitoring various athletic performance metrics, e.g., during the course of a game, a practice, a training session, training drills, and the like, are described. These systems and methods can provide useful metrics for players and coaches relating to athletic performances in various sports, including various team sports.

Systems, methods, apparatuses, and computer program products for contact-free heart rate monitoring and/or measurement are provided. One method may include receiving video(s) that include visual frame(s) of individual s) performing exercises, detecting some exposed skin from the video(s), and performing motion compensation to generate color signals for the exposed skin to precisely align frames of the exposed skin. The method may also include generating the color signals by estimating a skin color for each frame by taking a spatial average over pixels of a cheek of the face(s) for R, G, and B channels, respectively, applying an operation to remove remaining motion traces from the frames such that the heart rate traces dominate, and extracting and/or outputting the heart rate of the individuals using a frequency estimator of the skin color signals.

An exercise machine using motion sensor to track exercise, comprising: an exercise equipment, including a mainframe, the mainframe is fixed and won't be moved by user's movement, an operating mechanism, the operating mechanism is arranged on the mainframe and it will follow the movement of the user; wherein the operating mechanism having a motion sensor, inside the motion sensor having a multiple-axis tracking sensor module and a first microprocessor for detecting the height displacement of the operating mechanism and transmitting the height displacement signal to an electronic control device, then processing by a second microprocessor arranged inside the electronic control device to know whether the motion track of the user reach the preset position during exercise to ensure the effect of exercising.

A balance training system including a mobile plate configured to support a sole of a trainee in a standing state, a first member fixed on the mobile plate, a load distribution sensor including a plurality of sensors arranged in a matrix under the mobile plate and configured to detect a load received from the trainee riding on the mobile plate and a position of the first member, and a control unit configured to calculate a net moving amount of a center of gravity position of the trainee based on a difference between a moving amount of a center of gravity position of the load received from the trainee detected by the load distribution sensor and a moving amount of the position of the first member detected by the load distribution sensor and to control a movement of the mobile plate based on a result of the calculation.

Sports equipment and/or areas of play are provided, comprising a sports equipment or area of play and a sensor.

There is included a method and apparatus comprising computer code configured to cause a processor or processors to perform obtaining video data including at least one body part of a person, selecting keypoints of the at least one body part based on a predetermined rehabilitation category, extracting a motion feature of the at least one body part from the video data, scoring the motion feature based on the predetermined rehabilitation category, and generating a display illustrating the motion feature and said scoring of the motion feature.

Systems, devices and methods for managing personal activities and health regimens are provided. In some aspects, a control system comprising specialized computer hardware and software provides instruction(s), warning(s), penalty(ies), encouragement(s) and incentive(s) to a user, based on such a health regimen. In additional aspects, such instruction(s), warning(s), penalty(ies), encouragement(s) and incentive(s) are also based on data from specialized sensors tracking a user's personal activities within a personal activity space. In some aspects, instruction(s), warning(s), penalty(ies), encouragement(s) and incentive(s) are adjusted in real time, based on input from multiple users. In one example, a partial giveback reward is provided to a user, in which part of a regimen goal that is exceeded is provided back to the user as one such incentive.
