Including perspective in tactile diagrams for the visually impaired: A short communication

Andrea M Nguyen, Dianne TV Pawluk

We comment on our recent research findings on the effectiveness of adding local cues to graphical projection perspective to improve the understanding of perspective in tactile diagrams by individuals who are blind or visually impaired (BVIs). Local cues were added by indicating the depth of a point on an object with respect to the reader by the thickness of the line of a raised line graphic at that point. The findings suggest that adding the proposed local cues improves performance, which may further improve through training.
