laser. august 2008.
Here a second real laser draws the stroke you draw with the laserpointer. The laserpointer is tracked by turning off the second laser ~30 times a second for as long as the tracking camera needs to take a picture. This happens in sync with the tracking camera and therefore so precisely and quick that it is not noticeable for the human eye.
Below, my noticably proud self shows off the system to Theo, member of the team who built the original laser-tag system.
