“Using spatial gratings, the spatial acuity of the skin has been found to be about 1 mm.” “The temporal resolving capacity of the skin… can resolve temporal intervals as small as about 1.4 ms, increased to 5.5 ms when determining the minimum separation time between two 1-ms pulse stimuli that is required for an observer to perceive them as successive.” “Overall, the experimental data suggest that the hand is poorer than the eye and better than the ear in resolving find spatial details. On the other hand, [the hand] has proven to be better than the eye and poorer than the ear in resolving find temporal details.”
