The Rowing Motion Counter (RM counter) aids in teaching the concept of quantity for those learning to count. Our client has Leukodystrophy and has both physical and cognitive disabilities, which makes traditional methods of learning less effective. The RM counter translates a rowing type motion into an audio-based feedback device which counts the number of subsequent strokes. The device has two modes: one for “practice mode” in which the client can simply exercise the device with no particular goal, to become acquainted with the motion and the counting, and the second mode, called “game mode” which assigns a target value that must be acknowledged and reached. Designed for those with visual impairments and a varying degree of spasticity, the RM counter minimizes reliance on vision through the use of broad physical movements and corresponding audio feedback. The device itself utilizes a BASIC stamp microcontroller to manage inputs received from a potentiometer, perform necessary calculations, and to output saved audio files from a uMP3 mp3 player. The user-interface consists of a adjustable spring loaded, dampened set of scooter handlebars connected to a potentiometer which is read for voltage levels. This resistive element in the pulling motion is from the use of an residential door closer, where the adjustable spring and dampener are sealed for maximum safety. The entire device is mounted on a 0.12 inch thick plate of steel which slides easily into a slot in the client’s
