title: Lower Extremity Lateral Skin Stretch Perception for Haptic Feedback.
abstract: Tactile feedback in recent decades has allowed humans to receive information 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 use of a single actuator. Experiments were conducted to explore sensitivity to skin stretch on nine locations on the human lower leg. Thirty-two stimuli were presented to subjects, exploring effects of displacement (from 0.2-2.0 mm) and speed (from 0.5-4.0 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 (upper), and fibularis longus (lower) all had a mean accuracy of at least 85 percent and are suitable locations for a skin stretch tactile feedback device.
