>>> Jack can you either post the results or give me a web site or paper that give the experiment parameters along with the results. Was this a computer simulation of real data or a estimation of the movement from the video camera? <<<

Hi Dave

No, this was not a computer simulation. As I described above, the computer produced hard data of sensor trajectories from an array of motion detectors.

During the early 1900s, I spent a good number of hours with Professor Torres, Chair of the Physics Department at the U of CA (San Bernardino). Along with other physics labs, Professor Torres helped me to understand the physics principles that could produce the bat trajectories I had charted from overhead video.

A couple years later he called to see if I would be interested in using their newly acquired Motion studies computer to further my study. I was able to use the equipment a couple times a week for about six weeks. We placed the sensors as I described and received data on a number of local college player's swings. I would say the data was more valuable in validating my findings from video analysis than producing new findings.
