Haptic Color Patterns for Visually Impaired People-Pilot Study for a Learning Color Wheel

This study proposes a tactile diagram pattern for visually impaired people to recognize color information. The pattern uses the principle of three primary colors, with different patterns representing red, blue, and yellow. The size of tactile elements on these patterns indicates the proportion of the color mixing. A preliminary experiment showed that even a sighted participant could understand and reconstruct the tactile diagram. Future experiments will target visually impaired people to confirm the effectiveness of this method.
