Abstract

Based on a springboard with a force platform a complex measuring unit was developed to be used in springboard diving. The platform is composed of three plates, and based on the principle of strain measurement for vertical and horizontal forces. Using a computer based video system as a new component the board's angle of inclination can be measured automatically. After locating two markers of the springboard in the first picture, the video system tracks the markers during the board movement itself. Feedback pictures for the diver will be selected for defined events because of the synchronized data from force measuring and the board inclination. With this image of the diver and an added reference picture (model stick-figure) the difference between the model and the actual performance were shown to the athletes.
