Developing an Accessible, Multisensory Interface to Increase Graphical Information Access for Blind and Visually Impaired Students in STEM Disciplines
Publication Name: Developing an Accessible, Multisensory Interface to Increase Graphical Information Access for Blind and Visually Impaired Students in STEM Disciplines
Graphical representations of information are often inaccessible to blind and visually impaired (BVI) learners due to most information access technologies relying on visual interfaces. This is particularly problematic in STEM disciplines, where graphical content commonly conveys critical information. While visual information has traditionally been conveyed to BVI students through the use of embossed tactile graphics, these are far less available than materials provided to sighted students. To address this problem, the Cyber Learning application described here will provide information on the feasibility of using a vibro-tactile interface to present complex STEM-related images (e.g., mathematical diagrams or data visualizations) using multisensory cues via the touchscreen of a mobile device. This white paper explores our development process and discusses future work on this project.
