• "I can't name it, but I can perceive it" Conceptual and Operational Design of "Tactile Accuracy" Assisting Tactile Image Cognition

  Jiangtao Gong, Wenyuan Yu, Long Ni, Yang Jiao, Ye Liu, Xiaolan Fu, Yingqing Xu · 2020 · Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2020)

  This paper introduces "tactile accuracy," a new evaluation criterion for measuring how well blind people recognize objects in raised-line tactile images, replacing the conventional "naming accuracy" borrowed from visual image recognition research. The fundamental problem is that…

• Enabling Collaboration in Learning Computer Programing Inclusive of Children with Vision Impairments

  Anja Thieme, Cecily Morrison, Nicolas Villar, Martin Grayson, Siân Lindley · 2017 · Proceedings of the 2017 Conference on Designing Interactive Systems (DIS)

  This paper from Microsoft Research explores how Torino, a physical programming language, enables collaborative learning of computer programming by children aged 7-12 with mixed visual abilities — from full blindness to full sight. Torino uses tangible "instruction beads" (play,…

• 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 learning shapes and gestures,…
