Accessible Online Indoor Maps for Blind and Visually Impaired Users

Abstract

This paper proposes alternatives for the development and improvement of maps to aid accessibility. Based on our analysis, we present an accessible online indoor map prototype that complies with WCAG 2.0. For the case study, the prototype displays an indoor map that is designed using Scalable Vector Graphics (SVG) format. This format can include information that helps the screen reader to interpret the visual graph information. In addition, the prototype can simulate the route that the users select so they can get an idea of the environment where they will mobilize. We tested the prototype in different browsers with the help of blind people.
