Wayfinding board design for the visually impaired based on service design theory

Abstract

The visually impaired people have difficulty in finding positions in public places. Current wayfinding systems usually neglect the demand of the visually impaired people. Many studies have focused on designing the wayfinding system for the visually impaired people. But current researches have some disadvantages when applying. In this paper, a color related and QR code enhanced wayfinding system is proposed to provide wayfinding service for the visually impaired people. The design of the proposed system is based on the service design theory. The proposed system has the advantage of low cost, smooth update and high level of effect.
