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

TL;DR

This paper introduces a tactile diagram pattern based on primary colors to help visually impaired individuals recognize and understand color information, with preliminary tests indicating potential effectiveness.

Contribution

It presents a novel tactile color pattern design using primary colors and size variations to convey color mixing information for visually impaired users.

Findings

Sighted participants understood the tactile diagram.

Participants could reconstruct the tactile pattern.

The method shows promise for visually impaired users.

Abstract

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.
