tactiledatavisualization.jpgan original data visualization technique for sports purposes that is based on the principle that vibrations can convey information. a haptic sports vest uses tactile signals to prompt the wearer to optimise their technique or to use specific muscle groups. practically, sensors in the garments measure the speed at which a rower moves & how they coordinate their leg and body movements. if the rower deviates from the optimum speed or rhythm, pads worn at the ankle & waist start vibrating at the correct stroke intervals to help the rower recapture the winning action. an earpiece is an alternative, ‘but like the visual information system, the auditive information system is often overloaded. when a person needs his or her ears and eyes for other purposes, a third information stream becomes necessary.’ see also haptic shoes.
