The ArcAid system, demonstrated at CES 2014, consists of three cameras mounted behind a basketball backboard — two on the upper sides of the basket and one behind it.
The two upper cameras analyze the arc, speed, and angle of a basketball in mid-air. The third one checks to see if the user sinks the basket. A large screen displays the data and the adjustments needed for the user to make the basket, like aim farther to the left or shoot harder.” via PSFK
