• Evaluating Wrist-Based Haptic Feedback for Non-Visual Target Finding and Path Tracing on a 2D Surface

  Jonggi Hong, Alisha Pradhan, Jon E. Froehlich, Leah Findlater (2017) — Proceedings of the 19th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper investigates wrist-worn haptic wristbands as a means to provide directional hand guidance for blind and visually impaired users on a 2D surface. Precisely guiding a blind person's hand has applications ranging from tracing printed text to …
