A system for analysis of user gait and to provide correction in form of haptic and visual feedback. This system comprises a motion and force sensors and a haptic actuator embedded in the user shoe insoles in communication with a smart-phone based analysis application, configured to calculate motion and orientation of the user feet in relation to the value, location and distribution of ground reaction forces measured by sensors located in the shoe insoles and after analysis of said forces and motion, to provide haptic feedback to the user foot instructing about the location (and timing) of pressure the user must apply to achieve an optimal gait.

Systems and methods are disclosed for generating and providing guided practices and coaching feedback (e.g., illustrated in 3D images, video, or audio) that allow golfers to follow along to improve their physical swing in a digital environment. The feedback may be provided with 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 the guided practices and coaching feedback.

A display method executed by a processor includes: acquiring an identification result relating to any one of a plurality of elements included in a series of exercise and a position of an athlete that performs the elements based on 3D sensing data that is acquired by sensing the series of exercise by the athlete of a sport scored by a judge and an element dictionary data in which characteristics of an element and a position of the sport scored by a judge are defined; identifying any one of an element and a position that is being displayed in a 3D model video based on the 3D sensing data corresponding to the series of exercise, based on the identification result; and identifying, for the any one of the element and the position being displayed, time information corresponding to a boundary with any one of a next element and a next position.

The walking training system includes: a treadmill; a determination unit configured to determine whether a walking of the trainee on the treadmill is an abnormal walking based on predetermined abnormal walking symptoms; a display unit configured to display a result of a determination of each of the abnormal walking symptoms; a reception unit configured receive a selection of at least one result of the determination from the results of the determinations, each of which displayed on the display unit, in which regarding pieces of advice about adjustment items for improving the abnormal walking symptoms in the result of the determination which the reception unit has received the selection, the display unit preferentially displays the pieces of advice that are common to pieces of advice about adjustment items for improving the abnormal walking symptoms in a result of another determination in which the determination unit determines the abnormal walking.

Proposed is a golf analysis device with a calibration function, which includes a sensor unit configured to generate tracking data for at least one of a golf club moving by a user's swing motion and a golf ball hit by the user's swing motion; an analysis unit configured to generate a swing analysis value of the user by analyzing the tracking data; and a communication unit configured to transmit the swing analysis value to a user terminal, and receive calibration information on the swing analysis value from the user terminal. As a swing analysis value can be generated based on the calibration information received from the user terminal, the golf analysis device allows the user to receive very accurate swing analysis results.

A method and system for measuring exercise data using a plurality of wireless sensors is disclosed. The plurality of wireless sensors are attached onto or into a plurality of pieces of strength training equipment, wherein each individual wireless sensor from the plurality of wireless sensors is attached to and associated with an individual piece of strength training equipment of the plurality of pieces of strength training equipment. An individual piece of strength training equipment of the plurality of pieces of strength training equipment is selected and the wireless sensor is registered with selected piece of strength training equipment with a computing device. Strength training equipment details may be identified through the computing device.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

Systems and methods for providing a distortion-free pool-surface display beneath a swimmer. In one embodiment, projectors are positioned below a water level at opposite walls of a pool, and are configured to project images to a display surface at the bottom of the pool beneath a swimmer. A camera is used to view images projected by the projectors and to provide corresponding image data to an image correction platform on a graphics processing unit (GPU). The image correction platform identifies distortions in the images, generates image corrections that counter the identified distortions, and applies the corrections to subsequently projected images. The image correction platform also generates image adjustment that cause overlapping portions of the projected images to match seamlessly. The projected images may provide immersive experiences, coaching/training interfaces or other interactive displays.

A method of predicting the likelihood of a post T-off golf swing or consecutive swings resulting in a ball being sunk in a hole; the method utilizing communication equipped cameras or communication equipped laser rangefinders at known locations to determine accurate ball lie information. Transmission of this location information in real time to a processing facility linked to a database of historical play information incorporating at least ball position information and golf course in order to calculate odds of success of the upcoming swing and/or subsequent swings.

Disclosed is an exercise posture correction assistance method using working muscle information depending on motion performed by at least one server, including acquiring first image information containing movement of a user corresponding to a specific practice motion from a user terminal, deriving skeleton information corresponding to the movement of the user based on the first image information, generating second image information by indicating the movement of the user using a skeleton shape based on the first image information and the skeleton information, deriving muscle information corresponding to the specific practice motion from a database, generating muscle movement image information corresponding to the movement of the user based on the skeleton information and the muscle information, and providing the second image information and the muscle movement image information to the user terminal.
