Tactile and Sensory Interactions

The past three decades saw considerable progress in access to information for the group of blind and visually impaired people: Thanks to modern information technology in the mainstream and to very specialized adaptive and assistive technologies, blind and visually impaired people are now able to deal independently and efficiently with almost every piece of information that is composed of pure text. Despite current strong trends towards graphical presentation, text still covers the majority of relevant contents for private and professional life, such that information access for the target group is currently accomplished to a very large extent. Despite intensive research efforts carried out over the last years, blind and visually impaired people are still excluded from an efficient usage and handling of graphical contents. Since Mathematics is presented in a highly graphical way most of the time, this exclusion implies considerable restrictions in access to Mathematics, too. Although “accessibility” is put in place, “usability” and especially support functionalities in “doing” mathematics are very low. This paper analyses the major issues, outlines the existing approaches to a possible solution and describes the current activities at the Johannes Kepler University in Linz, institute “integriert studieren” (Austria) towards a comprehensive software answer to this problem.
