In order to identify strengths and weaknesses in the technical and tactical behaviour of table tennis players process oriented models of the match are constructed. Using these models, the temporal evolution of the match may be described. Parameters for describing the match include the positions of the ball when hitting the table. Feedback systems giving the player immediate acoustic or optical feedback in training on the position and/or quality of the ball just played may be applied in training. Methods for detecting the position, where the ball hits the table automatically (preferably in real time) would be advantageous in both cases. The applicability of techniques based on vibration diagnosis has been investigated.
