“…Vibrations stimuli that increasing in the order of the frontal head to the temporal head in chain reaction were effective for wall localization [7]. In contrast, vibration stimuli provided in isolation to a single position in the frontal direction of the head via a single vibro-motor were effective for aperture localization [8]. These results suggest that the effective vibration stimuli differ with respect to the localization of walls and apertures.…”

We have been developing a helmet-type spatial perception support system that provides the user with vibration stimuli in response to the distance variation to an obstacle. The purpose of this research is set to propose a method for generating vibration stimuli that appropriately represent two environmental elements, walls and apertures, and verify its effectiveness for the aperture passage perception. The five vibro-motors are positioned at directional angles of 0 degree in front, 30 and 60 degrees to left and right, and generate vibration stimuli of an intensity calculated by assigning appropriate damping weights. We set the distance-dependent damping weights separately for each directional angle in the calculation of the vibration intensity to be generated for each motor. Experimental results demonstrate that the subjects were able to pass through the aperture in approximately 91 % of trials. This suggests that the developed system and the proposed vibration stimuli generation method are effective in perceiving space from the vibration stimuli provided to the head.
