Alternative Concepts for Accessible Virtual Classrooms for Blind Users

Abstract

The use of virtual classrooms by blind users is hindered e.g. By inaccessible user interfaces, graphical and dynamical content, as well as synchronous communication. Based on a requirements catalogue for accessible virtual classrooms and existing concepts to eliminate barriers for blind learners, alternative concepts are presented for a two-dimensional Braille display. An evaluation using tactile paper prototyping indicates an improvement towards accessibility and equal usage for all participants.
