Vibrotactile spatial acuity on the torso: Effects of location and timingparameters

The processing of spatio-temporal vibrotactile patterns by the torso was examined in two experiments. The first investigated the spatial acuity as function of location on the torso. A uniform acuity between 2 and 3 cm was found, except on the body midline where acuity was about 1 cm. This favorable effect was hypothesized to be caused by...
