A golf system includes a striking area; a target area including a plurality of physical targets positioned at different locations relative to the striking area; and at least one sensing device for sensing one or more parameters regarding the travel of a physical golf ball. A processor is configured to: access a database including golf hole data, the golf hole data defining relative positions of a tee-off location and a pin location for a virtual golf hole; based on the one or more parameters regarding the travel of the physical golf ball struck from the striking area, update a virtual location of a virtual golf ball on the virtual golf hole; and generate signals to provide an indication of which of the plurality of physical targets represents a direction of the pin location based on the virtual location of the virtual golf ball and the locations of the physical targets.

An apparatus and method for repetitively training a golf swing is disclosed. In some embodiments of the present apparatus, foot placement guides are provided to align a golfer's stance relative to a golf ball on a tee. Motion and other data capture create a swing profile for the golfer's swing, which is compared to the swing of a golf Pro, thus giving swing feedback to the golfer. The apparatus automatically resets the ball position after the swing, allowing the golfer to repeat the swing based on the received feedback while isolating other variables (such as inaccurate resetting of foot position).

A launch monitor for golf training includes both a continuous wave radar transmitter and a frequency modulated continuous wave radar transmitter. A first set of golf ball trajectory parameters are estimated with the continuous wave radar transmitter and a second, different set of golf ball trajectory parameters are estimated with the frequency modulated continuous wave radar transmitter. The array of transmitters and receivers may be non-uniform.

The present invention is related to a device and method for sensing motion of sphere moving on plane using single-camera, and device and method for sensing motion of golf ball moving on putting mat that a low-cost single-camera is used for sensing a sports sphere moving on a plane as a target object, and the sports sphere can be detected without a separate dedicated lighting and a space in which the sphere moves can be recognized, so it can be used regardless of location with a simple configuration, away from the limitation that the installation position of the camera must be fixed.

A system that wirelessly integrates actual game equipment with a computer and the internet to allow players remotely located from one another to play a competitive real or 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 devices, all containing circuits, contact and or noncontact motion sensors coupled with signal processing and radio frequency transmitter circuitry to wirelessly communicate game performance information to a remote receiver-computer. The computer displays player information and visually simulates and controls a game between one or more local players or 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 and dynamic motion parameters.

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.

Electronic tracking systems are disclosed for assisting users with locating objects in a sporting environment. One such system includes a ball tracking component that tracks a game ball while moving in the sporting environment, and a heads up display that is worn by the user. This heads up display has an electronic display screen with a transparent display area that dynamically displays images within the user's field of view. A processor, which communicates with the ball tracking component and heads up display, is programmed to detect movement of the game ball, and responsively determine launch characteristics and/or flight characteristics of the moving game ball. The heads up display displays the launch/flight characteristics contemporaneous with an object indication adjacent to or superimposed over the moving game ball as the game ball is visible through the transparent display area of the display screen within the user's field of view.

A system determining a spin axis of a ball includes a radar transmitting a signal into a target area. The radar includes a minimum of three receivers arranged so that two pairs of receivers are not co-linear. The system also includes a Processing Unit (PU) receiving data from the radar and determining a radar range of frequencies received at a point in time corresponding to differing velocities relative to the radar of different portions of the ball as the ball is spinning. PU divides the radar frequency range into a plurality of frequency components and calculating, for each of the frequency components, an angular position associated therewith. PU identifies as a projection of the spin axis in a plane perpendicular to a line of sight from the radar to the ball, a line perpendicular to a line represented by the determined angular positions.
