A mark for club head measurement in use for measuring information about a state of a club head of a golf club and provided on the golf club includes a central portion formed with a pattern having a lightness lower than the periphery thereof and a peripheral portion formed with a pattern surrounding the periphery of the central portion and having a lightness higher than the central portion.

Proposed is a posture comparison and correction method using an application configured to check two golf images and result data in an overlapping state, the posture comparison and correction method being capable of analyzing an image of a user captured through a portable device, displaying the swing speed of a golf club, the swing angle of the golf club, the swing form of the golf club, the angle of a head of the golf club, the hitting angle of a golf ball, the speed of the golf ball, the flying distance of the golf ball, and the trajectory of the golf ball on a screen, and comparing the image of the user with an image of a pro golfer transmitted from a server on a single screen, whereby it is possible to correct the posture of the user.

An apparatus for natural torso and limbs tracking and feedback for electronic interaction with fall safety support. The apparatus comprises a body harness worn on the body of a user, a support structure designed to bear the weight of the user in the event of a stumble, trip, or fall, and a plurality of tethers attached at one end to the harness and at the other end to the support structure. One or more sensors are integrated into the system to measure aspects of the user's movement and used as input to control a computer system. In the event of stumble, trip, or fall, all of, or a portion of, the user's body weight is borne by the tethers as a safety mechanism to prevent injury. The system is designed to be used with virtual reality systems wherein the user's vision is blocked or obscured by a virtual reality visor.

A method of and apparatus (10) for providing a personalized audio-visual instructional aid for assisting a person (11) to emulate preferred positions and/or movements in undertaking an activity by capturing position and/or movement data of the person (11) or an object associated with and controlled by the person undertaking the activity using position and/or movement sensing devices such as MEMS sensors (13) on the person (11) or object and using a computer (16) to analyze and compare the captured data with pre-stored data relating to preferred positions and/or movement in undertaking the activity and generating a visual presentation (19) based on the differences between the captured position and/or movement of the person or object and the preferred positions and/or movement and adding to the generated visual presentation, audio instructional comments relating to the differences.

A motion analyzer for attachment to sports equipment. The motion analyzer may be constructed as one unitary piece and may include a base portion and an upper portion. The motion analyzer may collect and record motion data associated with movement of the sports equipment. The motion data may then be communicated to a mobile application which provides a user with a visual representation of the motion of the sports equipment. Further, a method of manufacturing a motion analyzer for attachment to sports equipment.

Methods and systems for detecting configuration states of a golf club and adjustment systems of a golf club, such as a shaft connection system. A golf club configuration detection system captures configuration data from the adjustment system of the golf club by a configuration detection device, such as a camera, a barcode scanner, or an RFID scanner. The captured configuration data is compared to reference configuration data to determine a configuration state of the adjustment system. Swing data and ball-flight data are tracked for golf-ball strikes with the golf club in the detected configuration state. Recommendations for configuration states may be generated based on the tracked data.

A sports training device includes a glove with a main body. The main body has a palm portion and a back portion. The main body is configured to receive a hand of a user. A plurality of finger receptacles is disposed on the main body. Each finger receptacle of the plurality of finger receptacles has a proximal end disposed adjacent to the main body and a distal end disposed opposite the proximal end. The plurality of finger receptacles includes a thumb receptacle, a first finger receptacle, and a second finger receptacle. Each of the distal end of the thumb receptacle, the distal end of the first finger receptacle, and the distal end of the second finger receptacle are open. A sensor is disposed on the glove and is configured to monitor a release of an object to be thrown.

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.

A sport apparatus comprising a shaft, wherein the shaft comprises a notch fitting and a sensor housing. The sensor housing comprises an alignment rib fitting, printed circuit board, rechargeable battery, one or more motion sensors, a transceiver, an inductive charging coil, among other necessary elements for the sport apparatus as described herein. A portion of the sensor housing resides within the shaft, wherein the alignment rib of the sensor housing mates with a notch or other locking mechanism of the shaft.

An activity state analyzer 10 configured to analyze an activity state of a cyclist during cycling includes: a sensor unit (21 to 26, 18) configured to acquire sensor data from a plurality of types of sensors including an acceleration sensor 21 and a gyroscope sensor 22 that are attached to a lower back of the cyclist, and a CPU 11 configured to analyze an activity state of the cyclist during cycling based on a detection output from the plurality of types of sensors of the sensor unit (21 to 26, 18).
