Refreshable tactile displays that move with the hand, such as those that resemble computer mice, can be utilized to display tactile graphics faster and more cost effectively to individuals who are blind and visually impaired than traditional paper methods of creating tactile diagrams. However, in tactile diagrams, the word labels can be as important as the diagram itself and so it is important that these displays can present Braille. In this work, we present and discuss findings from a study which used three methods of displaying Braille and tactile graphics simultaneously with a tactile mouse: Braille and graphics at the same amplitude level, Braille and graphics at different amplitude levels, and Braille with a box around it, The simplest method, Braille and graphics at the same amplitude, surprisingly proved to be the most effective.
