In this paper we pursue an investigation on the role of perceptual flow in the tactile domain, which appears to be a primary source for information such as shape, motion and softness. In this paper, we report on a set of psychophysical experiments involving how humans integrate incoherent tactile flow stimuli. Two experiments are reported, whereby discordant stimuli are conveyed to the subject by two different fingertips, or by two different families of mechanoreceptors in the same finger. Results from the first experiment show that, in these conditions, the tactile and the optic perceptive systems act in a very similar way. In the second experiment the interaction between tactile flow and friction generate an illusory phenomenon peculiar of the tactile system.
