A shot identifying module 220 identifies a flight distance of the golf ball and an angle of a direction from the measurement terminal 10 toward the golf ball with respect to a direction toward which the user terminal 10 is directed at a time of the measurement. A terminal position and orientation identifying module 222 identifies a terminal position and a terminal orientation. A ball position identifying module 224 identifies a ball position based on the terminal position, the terminal orientation, the flight distance of the golf ball, and the angle.

A system for computer-implemented golf shot analysis includes a tracking device and a computing device. The computing device accesses ball flight data generated by the tracking device in view of a predetermined gradient map and associated functionality to derive a performance metric that penalizes shots deemed to be offline.

A system includes a processor configured for leveraging reference ball flight data associated with an individual and a reference club having a reference loft angle to compute predicted ball flight characteristics for other candidate golf clubs having loft angles different from the reference loft angle. The predicted ball flight characteristics include predicted distances of golf shots the individual is expected to make using the candidate golf clubs that can further accommodate a computed recommendation of optimal loft angles for a consistently gapped golf club set.

Systems and methods are disclosed for generating 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 3D avatars.

A system for data collection during a game includes a positioning system for determining various locations of a user during the game, a tag reader for reading a passive RFID tag held in close proximity to the tag reader, and a processor for correlating the location of the user with the time at which a tag is read to enable action locations for the game to be determined.

An indicator assembly for a golf club capable of checking a swing trajectory according to the present invention comprises an indicator which is attached to one side of the head of the golf club, has a sheet shape, has a plurality of marks spaced at intervals, and is made of a material that can be scratched by the blow of a golf ball. The indicator assembly for a golf club capable of checking a swing trajectory according to the present invention includes the marks on the indicator that can leave a scratch by colliding with the golf ball, thereby specifying the location of the scratch to determine the user's swing trajectory and the type of the formed pitch.

In a first aspect, a system for monitoring a swing is provided that includes (1) a swing measurement device adapted to couple to a swinging object and to output a signal indicative of a characteristic of the swinging object; (2) a wireless transmitter coupled to the swing measurement device and adapted to wirelessly transmit the signal output by the swing measurement device; and (3) a wireless device adapted to receive the wirelessly transmitted signal and to provide information regarding the swinging object based on the received signal. The wireless device is a cellular telephone or personal digital assistant (PDA). Numerous other aspects are provided.

A system and methods for custom-fitting golf clubs and golf club components is disclosed. Data is generated by a tracking device as a plurality of golf swings are performed by an individual. The data comprises motion and orientation information associated with a golf ball and with a golf club. The data is displayed using a graphical user interface. A plurality of shot characteristics is determined from the data. The shot characteristics are used to recommend golf clubs and golf club components that adjust a golfer's swing where the golfer exhibits the plurality of shot characteristics.

The present embodiments provide systems and methods for aggregating measurements captured by different technologies during a golf swing. By capturing measurements using different technologies, more accurate measurements may be provided to a user by selecting from the measurements, offsetting measurements based on the technologies used, and aligning measurements between devices. Further, by aggregating measurements received from different devices, additional features and functionality may be provided to the user that is absent from any one device used alone. Additionally, by storing the aggregated measurements, users, club fitters and instructors may access and leverage larger databases of measurements to better understand the user's golf swing and to provide better recommendations and instruction to the user.

The present invention is a Golf Super Tag Multifunction Golf Swing Capture and Analysis device comprised of a printed circuit board mounted in a case attached to the end of the club grip or mounted along the club shaft containing sensors and electronic components. The sensor data associated with the golf club swing is processed by the microcontroller firmware that analyzes the physics of the golf swing to determine the various characteristics of the golf swing such as swing plane, club face orientation, club head speed, point of ball impact, etc. This data can be stored in onboard memory and/or relayed via Bluetooth Low Energy or other communication protocols for storage, further application processing and/or relay to web-based systems. The firmware is comprised of code that runs on the microcontroller to handle the microcontroller startup, wake up, power management, sensor control and sensor data, as well as Bluetooth (or other communication protocols).
