Systems for detecting a successful field goal are described herein. More specifically, the systems are directed at automated detection for a field goal attempt. The systems evaluate whether the football was kicked within the designated area (e.g., above the cross bar and between the two upright poles). The detection is performed through the use of cameras, lasers and detectors associated with the field goal post. In this way, the systems assist referees in determining the success of the field goal attempt.

The present disclosure discloses a method and system for 3D online sports athletics. The system comprises a cloud server and several head-mounted devices having a virtual reality function, wherein each of the head-mounted devices is paired with an intelligent terminal having a step counting function; a 3D scene virtualizing unit of the head-mounted device virtualizing a 3D online sports athletics scene to display the virtualized objects of all the head-mounted device users that participate in the sports athletics; a wirelessly connecting unit, during the process of the sports athletics, wirelessly connecting the intelligent terminal that it is paired with and the cloud server; and a processing unit acquiring, in real time, step counting data of the intelligent terminal that it is paired with and uploading the step counting data to the cloud server, and acquiring the step counting data of other head-mounted devices from the cloud server, driving the 3D scene virtualizing unit to display online the step counting data of each of the head-mounted device users in its 3D online running athletics scene, to realize sports athletics where a plurality of persons are simultaneously online. The present disclosure, by combining the head-mounted device and the intelligent terminals having a step counting function, can realize remote running appointment.

Systems and methods relating to evaluating the performance of a person playing basketball are described. The systems and methods can be used to provide an evaluation sequence that can determine and evaluate the performance level of a person at one or more basketball skills. The evaluation sequence for the person can include a first sequence of actions that are the same each person being evaluated for a particular skill and a second sequence of actions that is based on the results of the first sequence and may be different for each person. Once the first and second sequences have been completed by the person, the system can determine a performance level for the person for the skills being evaluated.

The present inventive concept relates to a virtual golf device comprising a display part showing a virtual golf course and a virtual golf ball, and a calculation part calculating a movement of the virtual golf ball corresponding to a real golf ball on the virtual golf course when a user hits the real golf ball. The display part provides an information section showing information related to a green region with a target point. If a location of the virtual golf ball on the virtual golf course before the user hits the real golf ball is named a first location, a location of the target point is named a second location and a direction from the first location to the second location is named a first direction, the information section shows a distance between the second location and an intersection point where an imaginary line passing the target point and having a second direction perpendicular to the first direction meets a border of the green region.

A method and system for using a low resolution image of a golfer's swing for analysis is disclosed. Cameras obtain images of various portions of a golfer's swing. A computer calculates parameters associated with a golfer and a golf club from the images. Parameters include body angles, head position, shoulder positions, arm positions, hand positions, leg positions, foot positions, club shaft angles, and club head position. Different portions of the swing are captured using the cameras, including a static initial address, a backswing, a downswing, a forward swing, and a follow-through. A computer uses measured parameters from two or more portions of the swing to determine comparative parameters during different portions of the swing. The computer uses the parameters to generate swing analysis outputs, including swing characteristic information and/or swing profile information. A correlation table relates identified swing analysis outputs to particular recommendations to the golfer to improve the swing.

A method for determining a relative performance measure between at least two players in a sport, comprising: receiving position information relating to each of the players and a sporting projectile as each player hits or receives the sporting projectile, and determining, based on an analysis of the position information, the relative performance measure between the players.

Methods for determining performance information for an object located within an area include obtaining magnetic field information for the area, measuring first magnetic field data when the object is located at a first position within the area, and determining performance information for the object within the area based on the magnetic field information for the area and the first magnetic field data.

A green simulation apparatus having a configurable upper surface with a changeable contour may comprise a covering forming the upper surface and a covering support assembly configured to support the covering. The support assembly may comprise a plurality of movable positioning elements having the covering resting thereon and positioned in an array extending in a reference plane and movable along axes extending substantially perpendicular to the reference plane. The support assembly may comprise a movement actuator configured to move at least one of the positioning elements independently of other positioning elements in the array.

An American style football including an inflatable bladder, a cover surrounding the bladder, a battery carried by the football, and a light emitter. The light emitter is carried by the football and is electrically connected to the battery. At least a portion of the cover transmits light from the light emitter.

A golf ball with embedded electronics to allow proximity to be tracked and to monitor golfer performance is disclosed. The golf ball comprises a processor connected to an accelerometer, communications circuitry, a spin detector, and memory, wherein the processor stores accelerometer data from the accelerometer and rotation data regarding rotation of the spin detector in the memory. The processor converts the data regarding the rotation of the spin detector into a rotation speed and a rotation direction, said rotation speed determined by a frequency of the data, and said rotation direction determined by a magnitude of the data. The communications circuitry is configured to communicate the accelerometer data, the rotation direction, and the rotation speed to a central interrogator for analysis of a golfer's performance.
