Vibrotactile adaptation impairs discrimination of fine, but not coarse, textures.


The effect of vibrotactile adaptation on the ability to discriminate textured surfaces was examined in three experiments. The surfaces were rectilinear arrays of pyramids produced by etching of silicon wafers. Adaptation to 100-Hz vibration severely hampered discrimination of surfaces with spatial periods below 100 microm (Experiment 1), but had little… (More)
