PROJECT TITLE :

Lower Extremity Lateral Skin Stretch Perception for Haptic Feedback

ABSTRACT:

Tactile feedback in recent decades has allowed humans to receive info through technology beyond traditional visual and auditory senses. Lateral skin stretch has the potential to be a mode of tactile feedback, reliably enabling the perception of directional cues through the employment of a single actuator. Experiments were conducted to explore sensitivity to skin stretch on 9 locations on the human lower leg. Thirty-2 stimuli were presented to subjects, exploring effects of displacement (from 0.2-2.zero mm) and speed (from 0.five-four.0 mm/s) on the perception of left and right directions. Higher accuracy came from stimuli having higher displacements and speeds. Three of the locations: soleus, calcaneal tendon (higher), and fibularis longus (lower) all had a mean accuracy of a minimum of 85 p.c and are appropriate locations for a skin stretch tactile feedback device.
