Abstract
Tactile perception is a complex process that relies on personal experience, surface topography and the methods we scanning the surface. Friction plays an important role on tactile perception, which is mediated by skin vibrations induced by tangential force between skin and surface. To establish the relationship between tactile perception and frictions, the latency and peak of P300 evoked by Oddball mode was observed and analyzed using an event related potentials collecting system. Three paper samples with different coefficient of friction were used for experiments. The result shows that the latency was small and peak value was large of P300 for sample with large coefficient of friction. It was opposite for small coefficient of friction.
