A system simultaneously tracks multiple objects. All or a subset of the objects includes a wireless receiver and a transmitter for providing an output. The system includes one or more wireless transmitters that send commands to the wireless receivers of the multiple objects instructing different subsets of the multiple objects to output (via their respective transmitter) at different times. The system also includes object sensors that receive output from the transmitters of the multiple objects and a computer system in communication with the object sensors. The computer system calculates locations of the multiple objects based on the sensed output from the multiple objects.

A method and system playing a game with a fully scoreable outfield at a golf entertainment venue are disclosed herein. The system includes golf ball tracking sensors, hitting bays and a server. The golf ball tracking sensors are positioned at a golf driving range. The hitting bays are also at the golf driving range, and each hitting bay has a video display.

In one instance, disclosed herein is a touch sensing sport ball system, including a casing that forms an exterior layer of a sport ball; a bladder disposed within the casing; a touch sensing layer disposed between the exterior layer and the bladder and operative to generate touch data when the sport ball is impacted; and at least one processor operative to: access the touch data generated by the touch sensing layer; determine, based at least in part on the touch data, that the sport ball has been impacted; and output an indication that the sport ball has been impacted.

A badminton intelligent training evaluation system, method and storage medium. The badminton intelligent training evaluation system includes a badminton racket, a serving device, two first image capturing devices and a computing device. When one or more instructions are executed by one or more processing units of the computing device, the one or more processing units perform the following procedures: obtaining and analyzing images of a player on the first half court to obtain a vacancy region with respect to the player instantly; controlling the serving device to serve a shuttlecock to fall in the vacancy region according to the obtained vacancy region; and obtaining an image of the shuttlecock returned by the player until falling on a landing point on a second half court, and determining whether the landing point is out of bounds.
