Project Description
Tactile overlays with audio annotations can increase the accessibility of touchscreens for blind users; however, preparing these overlays is complex and labor intensive. We introduce TacTILE, a novel toolchain to more easily create tactile overlays with audio annotations for arbitrary touchscreen graphics (e.g., graphs, pictures, maps). The workflow includes: (i) an annotation tool to add audio to graphical elements, (ii) a fabrication process that generates 3D-printed tactile overlays, and (iii) a custom app for the user to explore graphics with these overlays. We close with a pilot study with one blind participant who explores three examples (floor plan, photo, and chart), and a discussion of future work
