A multifunctional self-contained system that wirelessly integrates actual sports equipment with a computer providing critical feedback to improve all aspects of a player's game, and also allows players to play an actual competitive real or visually simulated game or sports with one or more players. Therefore, an individual player may opt to play solo or practice to improve basic golfing skills and techniques. The system includes sport implements that include, but are not limited to, smart golf clubs, a golf ball receptacle and a golf club motion sensing device, all containing circuits with contact sensors and or motion sensors coupled with signal processing and radio frequency transmitter circuitry to wirelessly communicate game status and performance parameters to a remote receiver and computer. The computer then optionally displays important parameters such as proximity of a sports implement contact face to an object, the impact of a sports implement with a sports equipment item, wherein the contact force, contact time, impact location, face angle, spatial orientation of a sports implement in motion, and the subsequent energy, velocity, and trajectory of game projectile such as a golf ball. The sports implements can be further equipped with motion sensing devices, and its motion and swing trajectory is visually simulated on the computer display. Standard sport implements which include, but are not limited to, golf clubs may be retrofitted with the device sensors and associated electronic circuitry to convert such clubs into “smart clubs” for use with the system. The system employs specially developed computer software to process player performance data, control game play, communicate game information to players, generate and control visual simulations, and display player performance information.

A golf club fitting apparatus and a method for fitting using the apparatus are provided. The golf club fitting apparatus may be attached to a golf club and provide fitting information including effective lie angle and effective loft angle. The golf club fitting apparatus includes a lower surface that contacts a butt end of a grip, an upper surface opposite the lower surface, and a side surface connecting the upper and lower surfaces. An angle indicator is disposed at a predetermined angle relative to a shaft axis of the golf club so as to rest in a neutral position when the golf club is in a normal address position.

Real-time sports competition is hosted by a server between remote opponents. The interactive sports game play involves sport specific tools simulating equipment used for in-person sports competition with projectiles. Opponents are paired for sports competition using the sport specific tools, including identifying opponents from the plurality of players to compete. A competitive sports game is hosted between the paired opponents by receiving input from each player sourced from a sport specific tool with sensors to determine motion of the specific sport tool caused by players, and wireless circuitry to transmit motion data to the user computers, wherein motion data includes at least velocity and impact force against a projectile. A winner of the competitive sports game can be determined.

A system that wirelessly integrates actual golf equipment with a computer and the internet to allow players remotely located from one another to play a competitive simulated game of golf. An individual player may opt to play solo or practice to improve basic golfing techniques. The system includes smart golf clubs, a golf ball receptacle and a golf club motion sensing device, all containing circuits and contact or motion sensors coupled with signal processing and radio frequency transmitter circuitry, thereby wirelessly communicate game performance information to a remote receiver-computer. The computer displays player information and visually simulates and controls a golf game between two players, via the internet, having similar equipment and remotely located from each other. Standard golf clubs may be retrofitted with the sensors and associated circuitry to convert such clubs into “smart clubs” for use with the system. The system employs specially developed computer software to process player performance data, control game play, communicate game information between players, generate and control visual simulations and display player performance information.

The golf club fitting apparatus may be attached to a golf club and provide fitting information including effective lie angle, effective loft angle, stroke plane, and aiming verification information. That golf club fitting apparatus includes a first opening for receiving a shaft, second openings for receiving a collimated light source, third openings for receiving angle indicators, and a recess for securing the collimated light source in an alternate configuration.

Novel tools and techniques for teaching a player the proper alignment when addressing a golf ball. In one aspect, such tools and techniques provide an alignment aid that allows the player to visualize both the intended target line of the shot as well as the position of the ball relative to the player's stance, allowing the player to easily modify his stance to obtain the proper alignment.
