Abstract

A sportball giving feedback as to manner in which it is handled or struck includes a ball body, and a plurality of sensors, a first wireless communication unit, and a controller located in the ball body. The sensors are arranged at different locations in the ball body, and are configured to sense pressures at different locations of the ball body, and generate electrical signals accordingly. The controller is configured to obtain the generated electrical signals, determine some characteristics of the pressures applied, and transmit the determined characteristics to the electronic device via the first wireless communication unit.
