Basketball shot-tracking system
A basketball shot-tracking system comprising a wrist tracker, a net tracker, and a shot-tracking mobile application. The wrist tracker is worn on the wrist or arm of a basketball player and the net tracker is attached to the net of the basketball hoop. The wrist tracker and net tracker automatically detect shot-attempt and made-shot events, respectively, and asynchronously transmit messages to the shot-tracking mobile application reporting these events. The shot-tracking mobile application, which runs on a mobile device, such as a smart phone or tablet computer, includes program instructions that, when executed by the CPU of the wireless mobile device, causes the wireless mobile device to automatically receive and process the asynchronous event data sent by the wrist tracker and net tracker, and to automatically tabulate, store and/or display the basketball player's shooting statistics (such as total shots taken, total shots made, shooting percentage, shot locations, and the like).
1. A wireless net tracker device comprising;
a microprocessor;
a computer memory storing one or more made shot profiles, each made shot profile representing typical perturbations of the net when a shot is made;
one or more sensors that detect actual perturbations of the net when a basketball passes through the net; and
a radio transmitter;
wherein the computer memory further stores a made shot detection program, the made shot detection program having program instructions that, when executed by the microprocessor, cause the microprocessor to analyze data generated by the one or more sensors and to determine whether a qualified match exists between the actual perturbations of the net and the typical perturbations of the net when a shot is made as represented by at least one of said made shot profiles; and
when the microprocessor determines that the qualified match exists, the program instructions are further configured to cause the microprocessor to transmit a message to a personal computer system via the radio transmitter, the message indicating that a made shot event has occurred.
2. The wireless net tracker of claim 1 , wherein the computer memory further stores one or more rim bounce profiles which represent typical perturbations of the net when a shot hits the basketball hoop's rim or backboard and does not pass through the net.
3. The wireless net tracker of claim 2 , wherein the computer memory further stores program instructions that, when executed by the microprocessor, cause the microprocessor to detect missed shots that hit and bounce off of the basketball hoop's rim or backboard by comparing the actual perturbations of the net with the typical perturbations of the net represented by the one or more rim bounce profiles.
