Figure 1: Informed by formative workshops that explored how haptic cues for fngerpad position and inclination support shape perception of data graphs (a-b), we introduce two refreshable, 1-DOF audio-haptic interfaces for data exploration. Slidetone (c) relies on fnger position with sonifcation, and Tilt-tone (d) relies on fngerpad contact inclination with sonifcation to provide shape feedback to users.
