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.

A method for adjusting a working state of an electronic device includes setting a reasonable value range of feature data of a user, and acquiring current feature data of the user from the camera device. The current feature data is compared to the reasonable value range of feature data. A working state of the electronic device is changed when the current feature data is out of the reasonable value range of feature data.

A treadmill and a control method for controlling the treadmill belt thereof are provided. The treadmill includes a treadmill belt, a first sensor, an image sensor, and a controller. The first sensor retrieves a light pattern or the image sensor measures the characteristic properties of the image of the user so as to control the treadmill belt. The light pattern can be generated by a signal member, which can be disposed on a side or both sides of the treadmill belt.

Systems and methods for creating personalized exercise programs are disclosed. An image capture device and a computer device are used to capture images of a user while the user performs athletic movements. The images may then be evaluated to create a human movement screen score. The human movement screen score, goal and time commitment information may then be used to create a personalized exercise program tailored to the specific user.

Technologies are provided for generation of exertion-aware paths. Some embodiments include a computing system that can generate a path based at least on first data defining a terrain, second data defining a target level of total work, and third data defining a target level of perceived difficulty. The computing system also can generate a road surface along the path. Generating the road includes embedding metadata defining position-dependent resistance forces based on a physics model, the metadata controlling force feedback at virtual-reality equipment. The computing system also can supply the road surface to the virtual-reality equipment.

A method of varying a dynamic resistive force during a strength training exercise includes receiving a selection of the strength training exercise from a set of available strength training exercises and obtaining exercise logic for the strength training exercise from computer memory. The exercise logic provides instructions for generating a vector that defines the dynamic resistive force provided at an end effector of a strength training apparatus during the strength training exercise. The method includes determining a real-time geometric arrangement of a plurality of cables coupled to the end effector, generating, based on the real-time geometric arrangement of the plurality of cables and the exercise logic, time-varying operating setpoints for a plurality of actuator assemblies coupled to the plurality of cables, and exerting the dynamic resistive force at the end effector by controlling the plurality of actuator assemblies in accordance with the time-varying operating setpoints.

An objective of the present invention is to provide exercise equipment which can provide a user with an immersive experience that allows the user to feel like they are there, while reducing unease or discomfort on the part of the user. The exercise equipment comprises: an exercise device for allowing a user to carry out a prescribed exercise; a measurement device which measures a viewpoint position of the user in a prescribed reference coordinate system when the user carries out the exercise using the exercise device; and a video device which generates and displays a display image of an object in a virtual space of the reference coordinate system on a fixed screen according to the viewpoint position, the display image simulating how the object would appear when viewed from the viewpoint position through the screen.

A captured video image obtaining unit 70 obtains a captured video image in which a player making a golf swing is captured. A swing path type specifying unit 86 specifies at least one reference angle based on at least one of a position of a predetermined body part of the player at address or a position of a shaft at address, where the positions are specified based on the captured video image. A swing path type specifying unit 86 specifies a downswing angle of a club head captured in a captured video image based on the captured video image. The swing path type specifying unit 86 compares the reference angle with the downswing angle.

A system and method for implementing a virtual fitness application are disclosed. Embodiments may be built for various platforms, including web browsers and mobile phones. One embodiment uses pose estimation to count the repetitive motions of a fitness activity (e.g., running). In one embodiment, to count the repetitive motions, a repetitive motion counting process is used that is based on computing differences of Y-coordinates of key points of the user. The repetitive motion counting process includes selecting a proper pose of the user; computing one or more delta values (corresponding to Y-coordinate changes of the key points); and counting a given user movement as a repetitive motion based on a function (e.g., average) of the delta values. One embodiment uses the pose estimation and repetitive motion count results to provide a gamified experience, for example, a leaderboard, a stats report, instant visual feedback, badges, coins, and a social experience.

Described herein are systems and methods for favorably coordinating a timing relationship between a musculoskeletal activity cycle and a cardiac cycle of a user. A method may include repetitively detecting a signal that correlates to a blood volume in the user; determining an actual value of the signal that varies with the timing relationship; computing a trend of the actual value of the signal; and adjusting the movement guidance based on the trend of the actual value. A system may include a prompt device configured to provide recurrently a movement guidance to the user for guiding performance of the rhythmic musculoskeletal activity; a sensor configured to provide a signal that correlates to a blood volume in the user; and a processor configured to determine an actual value of the signal that varies with the timing relationship and to adjust the movement guidance based on the trend of the actual value.
