The invention discloses an upper limb joint movement degree measuring method based on a Kinect sensor, comprising measuring projects of measuring shoulder joint buckling / stretching and adduction / abduction, elbow buckling / stretching, upper limb palmarflexion / dosal flexion and radial deviation / ulnar deviation and the like. In a measuring process, a sensing man-machine interaction manner is adopted and a position of each joint of an upper limb is captured through the Kinect sensor according to the movement of the upper limb of a detected person, so as to record, calculate and feed back joint movement degree information in real time, automatically finish measurement and directly obtain a measured result in real time; and therefore, the operation is simple and convenient. A user can select measurement projects by oneself; and in each project, the user can execute the movement of the upper limb according to an initial body position for promoting accurate measurement. When the executing movement does not accord with measurement requirements, a system has an error, and prompts and corrects unreasonable movement and postures by the user in time.

The present device relates to an apparatus and a method for allowing a golfer to properly grip a golf club. A proper grip is one that allows for the most efficient radial deviation (abduction) and ulnar deviation (adduction) as well as flexion and extension of the wrist of the golfer's upper hand, while also minimizing club head and shaft axis rotation during a golf swing. This grip can be achieved through the use of a marking system comprising the golfer's glove and the grip of the golf club. By matching one or more markings on the glove, placed in specific locations on its anterior, with one or more markings located on specific positions on a golf club grip, the proper location of the golfer's upper hand can be found and the proper grip can then be made.
