A non-transitory recording medium storing an information processing program executable by a computer to perform processing, the processing comprising: acquiring a sound signal collected by a microphone provided in a venue including a skating rink, and a first video obtained by photographing a competitor on the skating rink; estimating a takeoff-from-ice time and a landing-on-ice time of a jump performed by the competitor according to a silencing and a return of an ice sound based on the sound signal; and synchronizing time information of the sound signal with time information of the first video, and specifying each of a location corresponding to the takeoff-from-ice time and a location corresponding to the landing-on-ice time in a trajectory of a location of the competitor on the skating rink based on the first video.

A ball tracking and scoring system and also enables a game implementation system using this system.

An interactive exercise apparatus for guiding a user to perform exercises includes a frame, a mirror, a display device, a driving mechanism, a determination unit, and a control unit. The mirror is movably mounted on the frame and configured to reflect an image of the user. The display device is disposed on a backside of the mirror and visible through the mirror. The driving mechanism is mounted between the frame and the mirror for electrically driving the mirror to move with respect to the frame. The determination unit is configured to determine location or posture of the user who performing the exercise. The control unit is operable to control the driving mechanism according to the location or posture of the user identified by the determination unit so as to control the mirror to move to a suitable position where the user can see their reflected image.

A treadmill with a safety warning function includes a miming unit, a driving unit, a detection unit and a control unit. The running unit includes a driving roller and a running belt provided for a runner to stand thereon. The detection unit includes a camera arranged at a predefined height range on top of the running belt for photographing images. The control unit determines a height of the runner based on the images photographed. The safety monitoring method for the treadmill includes obtaining an image above the running belt and determining whether the height of the runner is greater than the predefined height. By determining whether the height of the runner is greater than the predefined height, it is able to determine whether the driving roller can be driven by the driving unit to rotate, thereby preventing the hazard of accidental activation by a child of insufficient height.

Systems and methods are disclosed for generating a 3D avatar using a biomechanical analysis of observed actions with a focus on representing actions through computer-generated 3D avatars. Physical quantities of biomechanical actions can be measured from the observations, and the system can analyze these values, compare them to target or optimal values, and use the observations and known biomechanical capabilities to generate 3D avatars.

Some embodiments include an outer tube, a pivot structure, an inner tube, a rotational element, and a central rod. The pivot structure perpendicularly intersects the outer tube at a midpoint of the outer tube. The inner tube is coaxially within the outer tube. A first portion of the inner tube is within the outer tube on one side of the pivot structure. A second portion of the inner tube is within the outer tube on another side of the pivot structure. The rotational element couples to the pivot structure, rotates about an axis of the pivot structure, and interfaces with the first and second portions of the inner tube to cause rotation of one portion of the inner tube in a first rotational direction to counter-rotate the other portion of the inner tube in a second rotational direction. The central rod is within the inner tube and translates axially.

A treadmill may include two separate left and right belts rotating around two sets of rollers, four legs having an adjustable height via air suspension to customize an inclination of the treadmill, a thermoelectric assembly, a fragrance assembly having a rotating fragrance cartridge to emit various smells toward a user of the treadmill, a display on which exercise programs are played, and an attachment module having a dispensing tray on which treats are dispensed. A handle of the treadmill may have a sensor to sense a height and front-rear position, and a belt divider provided between the left and right belts may have position or proximity sensors to sense a left-right position. An inclination of the treadmill may be automatically adjusted according to positions detected by the sensors, and the fragrance assembly, attachment module, and inclination may be automatically operated in accordance with an exercise program played on the display.

A method controls a piece of exercise equipment when a user of the exercise equipment is using a virtual reality headset. The method begins by receiving sensor inputs detecting a position of the user with respect to the exercise equipment. An operational zone of the exercise equipment is then determined. It is then identified when the user is moving toward a warning area within the operational zone of the exercise equipment. The method then sends signals to the virtual reality headset. Based on the signals, the virtual reality headset creates audible and visual outputs to instruct the user to move back fully into the operational zone of the exercise equipment.

This disclosure relates to a relatively compact smart ball launching system and associated methods for using the same. In various embodiments, the disclosed ball launching system may comprise a collapsible ball hopper that can store a larger number of balls while maintaining a relatively compact size. In certain embodiments, brushless motors may be used to improve power efficiency while allowing for accurate launch speeds and/or spins. In some embodiments, a pre-launch chamber may be included in a ball dispensing mechanism that may facilitate on-demand shots and/or power savings by shutting the ball launching system down when the ball hopper is empty. In further embodiments, the ball launching system may be controlled, at least in part, via a mobile device. In some implementations, the ball launching system may include and/or otherwise interface with a camera system to facilitate improved calibration and/or record user actions.

The rehabilitation training system includes: an evaluation unit configured to evaluate rehabilitation training performed by a trainee; a storage unit configured to store a plurality of evaluation comments regarding the evaluation; a reception unit configured to receive, from an authorized training assistant, designation of an evaluation comment that is restricted from being presented to a specific trainee among the plurality of evaluation comments; a selection unit configured to select an evaluation comment to be presented to the specific trainee from the plurality of evaluation comments based on the evaluation for the rehabilitation training of the specific trainee that is performed by the evaluation unit and the designation; and a presentation unit configured to present the evaluation comment selected by the selection unit.
