The three next space was chosen to order that the subjects could sharp domination the positioning of the ball. The position of the ball at starting and end positions was monitored by LED-photocell detectors. The signals from these detectors were monitored by a PC and allowed for automation of the training, including liberation of pre-recorded viva voce instructions.
