I dont even think you need a sensor in the cue ball you just need high speed camera, measle ball with different color/shape dots, and the right software.My statement that pool needs more statistics wasn't meant to mean that it would solve the issues that pool faces.
I think that pool would be more interesting if they're were other stats available such as spin rate on cue ball, object ball speed, cue ball speed, rate of slide vs. rolling, cue ball distance from rail, avg of cue ball distance from rail, total cue ball travel in a match, etc. etc. Maybe you can add more.
Maybe one of the ball makers can add RFID technology to the balls to make this happen. Then we could have measurable stats that lets players compare themselves and have bench marks for possible handicapping that is fair and not subjective which in turn could help grow the game.
