A display apparatus may include: a camera; a display; a memory storing one or more instructions; and at least one processor configured to execute the one or more instructions stored in the memory to: analyze an image captured by the camera and detect a free space included in the image; determine an exercise motion performable in the free space, based on the detected free space; and control the display to output exercise content based on the determined exercise motion.

Systems and methods are disclosed for generating a 3D avatar and object fitting recommendations 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 the 3D avatars and object fitting recommendations.

A punch-and-cycle exercise device is described. The device includes a cycling mechanism, a frame to which a punch-pad is attached, a plurality of delineated target zones arranged on the punch pad, a sensor unit that may include an impact sensor, an accelerometer, and a single or plurality of hall effect sensors, each communicatively connected to the target zones. A control unit communicatively connects with the sensors, a punch-pad mounted camera, and a display. Gloves with built in magnets and/or unique markings/visual identifiers interact with the sensors and/or camera and provide data to the controller to track user success at responding with correct puncing form to illuminated and sequenced punching programs while cycling. Output can be displayed locally or on any paired device.

A basketball system comprising a court system having shot locations defined by shot location lines on the play surface and the shot areas defined by shot area lines on the play surface, and a goal system comprising a respective backboard suspended above the play surface at each opposing farthest end of the play surface, an instrumentation system comprises sensors to detect activities within the boundary line of the court system, and a respective penalty box for each team in which players, coaches, and referees can serve a penalty assessed for an infraction.

A method of creating a scalable dynamic jointed skeleton (DJS) model for enhancing psychomotor leaning using augmented cognition methods realized by an artificial intelligence (AI) engine or image processor. The method involves extracting a DJS model from either live motion images of video files of an athlete, teacher, or expert to create a scalable reference model for using in training, whereby the AI engine extracts physical attributes of the subject including arm length, length, torso length as well as capturing successive movements of a motor skill such as swinging a gold club including position, stance, club position, swing velocity and acceleration, twisting, and more.

A trajectory and a flight distance of a target moving body such as a ball hit by a golf club in an athletic competition such as a golf game may be calculated from the images having been taken. The calculation may be conducted from the pictures having been taken with a monocular camera of low resolution such as a smartphone. An initial velocity and a hitting angle of a target moving body such as a ball having been hit high by the golf club may be calculated.

A system for detecting a ball or strike in baseball.

A method for portable drill instruction for a sport can include: capturing a live video of a player of the sport in a venue for the sport playing a ball launched from a ball machine during a training drill for the player conducted in the venue; determining in response to the live video whether or not the player satisfies a training goal of the training drill when playing the ball; and providing a real-time feedback to the player during the training drill that indicates to the player whether or not the training goal is satisfied.

A speed control system and method for controlling the speed of an endless belt loop of a treadmill. The speed control system comprises a plurality of image sensors, each image sensor configured to take an image of a user of the treadmill; and a controller configured to control the speed of the endless belt loop by (a) receiving the images of the user taken by the image sensors, (b) rectifying the images based on a calibration of the image sensors, (c) comparing the images to form a disparity map, (d) determining a distance of a user of the treadmill relative to the treadmill using the disparity map, and (e) calculating velocity or acceleration of the treadmill based on the determined distance of the user.

A performance scanning system that operates to detect and measure surface parameters of a portion of an athlete and uses the surface parameters to determine the likelihood that the athlete's physical performance has been or will be impaired.
