Indentation of skin.

Local skin indentation in the 5–20 Hz range generates cues that allowed participants to make discrimination based on the overall spatial pattern of stimulation, i.e. shape. In contrast, in the 40–80 Hz range, shape cannot be discerned, but skin stretch and the rate of its variation continue to inform the percept of roughness. ...Jun 17, 2022 ...
