Types of Stimuli and Experimental Setup (IMAGE) Kumamoto University Caption Three types of experimental stimuli were used, tactile only (a), visuotactile (b), and visual only (c). Participants and partners (when needed) stood opposite each other and placed their heads against an apparatus to keep their viewing distance constant (d). A projector displayed an image of the fixation point and a moving circle on the surface of a table (d & e). Participants had a vibrotactile stimulator attached to their index finger and were instructed to press the response key when they detected any of the stimuli (e).
