| Abstract | We report an experiment that presented visually impaired and sighted users with virtually rendered haptic two-line graphs of various orientations. Participants made a forced-choice decision on whether a stimulus was convergent, parallel, or divergent. The use of complex linear haptic graphs was investigated. Possible variations in performance patterns for overall two-line orientations of 0 (vertical), 30, 60, and 90 (horizontal) were explored in view of any haptic oblique effect. No difference between visually impaired and sighted participants was found. Overall orientation and degree of convergence showed an effect. The results are discussed in view of using forcefeedback devices in data visualisation for the blind. |
