Project Overview A system designed to attach to a pool cue with embedded sensors that measure the motion of the cue as a stroke is being made. Connects to a receiver system via Bluetooth to transmit the data to a computer for interpretation. This is designed as a teaching aid to allow a player to become a better pool player by being able to visualize the errors in his or her stroke thus allowing them to be corrected.

Project Overview A pool cue containing a 3-axis accelerometer, a 1- axis gyroscope, a 2-axis gyroscope, a Bluetooth transceiver, processor and a battery. A receiver that records video and processes data from the pool cue and sends measurements to a computer. A computer will display video of the player stroking, and give 3-D visual feedback on the strengths and weaknesses of the player's stroke. Team ACRONYM10/08/2009Mike
