A system, device and method for generating date representative of a person and using that data as criteria in a selection made for that person. The system includes a device worn on or adjacent to a user's foot. The device includes sensing means with an accelerometer and/or gyroscope and/or pressure sensing means to measure parameters of a person's foot during physical activities. The parameter data is collected and transmitted to a data processing means to generate a representative data group for the person. Matching means compare the representative data group to data stored in memory. Group data includes data representative of a range of footwear. Indication means are controlled to indicate, from the result of the matching means, any of the range of footwear which are selected.

The present invention relates to a golf swing training aid rod for teaching a golfer the proper golf swing and arm control for execution a golf stroke. In particular, the golf swing training aid rod includes an elongated shaft having a reference tip located at a first end of the elongated shaft and an attachment member located at a second end of the elongated shaft, and an axilla support member having an axilla side, an inner bicep side, and an attachment receiving member, the attachment receiving member is coupled to the attachment member of the elongated shaft, the axilla support member is configured to be inserted and held in place between an inner bicep and an axilla member of the golfer, and the golf swing training aid rod provides the visual and tactile feedback to the golfer while executing the golf stroke.

The present invention discloses a running parameters detection system for treadmills and detection method thereof, wherein the system detects the running change data generated by a user running on a treadmill configured with a running belt, a motor and an electronic circuit device by means of a sensor, as well as the running belt operation speed data of the treadmill, in which the running change data is the current data or vertical acceleration data; subsequently, the running change data can be further applied to determine the touchdown moment recording point and the off-ground moment recording point, thereby then, based on such two time points, further calculating various kinematic parameters, e.g., touchdown time, in-the-air time, stride frequency, stride length and vertical amplitude or the like; for example, such five kinematic parameters can be utilized for scientifically monitoring and training runners.

Provided is a riding posture outputting device that is able to determine a riding posture with accuracy. The riding posture outputting device includes a communication unit which acquires a crank rotation angle of a bicycle, and a propulsion force and a loss force which are added to a crank in the crank rotation angle , and a determination unit which determines whether a user is dancing on the basis of the crank rotation angle when the load calculated from the propulsion force Ft and the loss force Fr is maximized. Then, the communication unit outputs a determination result obtained by the determination of the determination unit.

Implementations generally relate to determining golf swing characteristics. In some implementations, a method includes obtaining a video of a person performing an action. The method further includes determining from the video a plurality of points associated with the person, where the determining of the plurality of points is performed for each frame of the video. The method further includes determining a plurality of three-dimensional (3D) coordinates for each point of the plurality of points, where the determining of the 3D coordinates is performed for each frame of the video. The method further includes determining a movement of the plurality of points based at least in part on the 3D coordinates. The method further includes determining one or more movement errors based at least in part on the movement of the plurality of points.

Implementations generally relate to determining a kinematic sequence. In some implementations, a method includes obtaining a video of a person performing an action. The method further includes determining from the video a plurality of points associated with the person, where the determining of the plurality of points is performed for each frame of the video. The method further includes converting two-dimensional (2D) coordinates of the plurality of points to three-dimensional (3D) coordinates, where the converting is performed for each frame of the video. The method further includes determining a movement of the plurality of points based at least in part on the 3D coordinates.

An electronic device includes: a communication interface configured to receive medical data of a user from a server; at least one processor electrically connected to the communication module; and a memory electrically connected to the at least one processor. The at least one processor is configured to: determine whether the user is in a rehabilitation condition based on the received medical data; when the user is determined to be in the rehabilitation condition, provide an exercise program corresponding to a recovery target part of the user using the received medical data; and provide feedback on the exercise program based on at least one of exercise performance data, biometric information, or an exercise-related recovery level of the user.

A headset including a speaker, a motion sensor, a transceiver, and a processor is provided. The speaker plays audio data. The motion sensor senses a posture of a user to generate first sensing data. The transceiver performs data transmission with an external device. The processor is coupled to the motion sensor and the transceiver. The processor determines whether the posture is correct according to the first sensing data to generate an output result and transmits the output result through the transceiver.

A system and method for using a body joystick to interact with a virtual or mixed-reality machines or software applications that uses a support arm to hold a device for attaching the body joystick to a user's body, a sensor for detecting movement, and a tether and actuator for providing feedback to the user about interactions with the virtual or mixed-reality machines or software applications.
