This describes an experiment on touch, modeled after the visual illusion where our eye interprets motion backwards and forwards (somewhat like the wheel caps on a car appear to move forward at low speed, but backward at high speed).
"When volunteer subjects were given the diagonally alternating [tactile] stimuli, they perceived them as moving smoothly back and forth--and just as with the visual illusion, the direction of apparent motion flipped back and forth from vertical to horizontal, on average about twice per minute, even though there was no change in the stimulus itself."That covers vision and touch. I will have to dig up an analysis of "phantom sounds" (common for cell phone uses). Then there will just be smell and taste!
