• 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,…

• Participatory Design Using Sensory Substitution Devices with Tactile and Audio Feedback

  Ella Tuson, Samantha Hughson, Christina Zymaris, Ryan King · 2017 · Proceedings of the 19th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This student research paper describes a participatory design study with a single blind participant (TC, blind from birth) to develop a sensory substitution device that provides a physical experience of spatial awareness through tactile or auditory feedback. The study was…

• The Tangible Desktop: A Multimodal Approach to Nonvisual Computing

  Mark S. Baldwin, Gillian R. Hayes, Oliver L. Haimson, Jennifer Mankoff, Scott E. Hudson · 2017 · ACM Transactions on Accessible Computing

  This paper identifies fundamental limitations of audio-only computer interfaces for blind and low-vision users and proposes a multimodal tangible alternative. The researchers conducted a 4-month field study at EmpowerTech, a computer training school for adults who are blind or…

• Principles for Designing Large-Format Refreshable Haptic Graphics Using Touchscreen Devices: An Evaluation of Nonvisual Panning Methods

  Hari Prasath Palani, Nicholas A. Giudice · 2017 · ACM Transactions on Accessible Computing

  This paper addresses a fundamental challenge in touchscreen-based accessibility: how to provide non-visual access to large-format graphical materials like maps that exceed the device's screen size. While touchscreens represent the fastest-growing computing platform among people…

• Multimodal Perception of Histological Images for Persons Who Are Blind or Visually Impaired

  Ting Zhang, Bradley S. Duerstock, Juan P. Wachs · 2017 · ACM Transactions on Accessible Computing

  This research addresses a critical barrier preventing blind or visually impaired (BVI) students and scientists from participating in STEM laboratory work: the inability to perceive real-time visual scientific data from instruments like light microscopes. While tactile graphics…
