Tactile feedback is an important component in the learning of motor skills such as dancing, sports, and physical rehabilitation. A suit with white dots recognized by a vision system to determine arm joint positions with millimetric precision was developed. This suit is worn by both teacher and student to provide position information. (Lieberman, 2007). If there is a difference between the teacher’s positions and that of the student, vibrational feedback is provided to the student through eight strategically placed vibrotactile actuators in the wrist and arm. This placement takes advantage of a sensory effect known as cutaneous rabbit that tricks the subject to feel uniformly spaced stimuli in places where the actuators are not present. These stimuli help the student adjust to correct the motion. In summary, the system consists of an instructor and a student having their movements followed by the vision system. Their movements are fed into a computer that finds the differences between their joint positions and provides proportional vibrational strength feedback to the student. Draw a block diagram describing the system design.
