A special supplement to this week's Time Magazine called Time Global Business profiled an athletic performance visualization company called Dartfish. Dartfish uses digital video technology to show athletes and coaches the mechanics of different activities performed in sporting events.

The key technologies that Dartfish offers are Simulcam which overlays two separate performances on each other, and StroMotion which merges multiple video frames together to highlight an athlete's position or trajectory. These can be used for entertainment or instructional purposes.

Dartfish has come up with applications in about 20 different sports. Their website has some really interesting information on it, including a number of illustrative still images and video. [ photo courtesy of Dartfish ]
