Computerised Pool Trainer

I was talking to someone on the weekend about how he had come up with an idea for a computerised pool trainer which would use a laser to project the pool balls' path on the pool table. This sounds like a great idea but has it been done before?

Unfortunately for him it already exists and there's even video of the "Automatic Pool Trainer" in action at a demonstration in Denmark:

As you can see from the video; the trainer uses standard pool equipment including the table, the cue, and the balls. The trainer simply projects data onto the felt of the pool table from a video projector above the table.

Please leave a comment if you know of any other pool trainers and if you have any other questions which you'd like me to answer please send an email to Ben Dash at ben.dash@gmail.com
