Line graphs stand as an established information visualisation and analysis technique taught at various levels of difficulty according to standard Mathematics curricula. Blind individuals cannot use line graphs as a visualisation and analytic tool because they currently primarily exist in the visual medium. The research described in this paper aims at making line graphs accessible to blind students through auditory and haptic media. We describe (1) our design space for representing line graphs, (2) the technology we use to develop our prototypes and (3) the insights from our preliminary work.

This study examined the relationship between the employment status of visually impaired college graduates in Great Britain and their social networks, both formal and informal. The unemployed graduates had less extensive support networks to help them find jobs; used contacts in less directive ways; and socialized in more structured, group-centered ways than did the employed graduates.
