A multichannel tactile feedback system was developed to test human subjects' sensitivity and discrimination ability using different vibration patterns. Small vibrating motors were attached to the body, and subjects reported on their sensation comparing the left and right side of the body (arms, ankles, and wrists) in a 2-channel signal presentation. Results showed that the most sensitive spot is the wrist position, followed by the ankles. Furthermore, changes in the vibration frequency are challenging to detect; thus, using different temporal patterns of the signals is more straightforward in an actual application.
