From Human-to-Human Touch to Peripheral Nerve Responses
IEEE World Haptics Conference
Human-to-human touch conveys rich, meaningful social and emotional sentiment. At present, however, we understand neither the physical attributes that underlie such touch, nor how the attributes evoke responses in unique types of peripheral afferents. Indeed, nearly all electrophysiological studies use well-controlled but non-ecological stimuli. Here, we develop motion tracking and algorithms to quantify physical attributes – indentation depth, shear velocity, contact area, and distance to the cutaneous sensory space (receptive field) of the afferent – underlying human-to-human touch.
