• "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…

• Travelling more independently: A Requirements Analysis for Accessible Journeys to Unknown Buildings for People with Visual Impairments

  Christin Engel, Karin Müller, Angela Constantinescu, Claudia Loitsch, Vanessa Petrausch, Gerhard Weber, Rainer Stiefelhagen · 2020 · Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2020)

  This paper presents a comprehensive survey with 106 people with visual impairments (63 blind, 43 low vision; ages 8-77, mean 46; predominantly German) examining how they plan and carry out journeys to unknown buildings. Unlike previous studies that focused on isolated aspects of…

• Visual Content Considered Private by People Who are Blind

  Abigale Stangl, Kristina Shiroma, Bo Xie, Kenneth R. Fleischmann, Danna Gurari · 2020 · Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2020)

  This paper presents the first empirical study investigating what types of visual content people who are blind consider private, in the context of their use of Visual Interpreters or Description Services (VIDS) — services like Seeing AI, Aira, Be My Eyes, and TapTapSee that…

• Deconstructing a "puzzle" of visual experiences of blind and low-vision visual artists

  Yulia Zhiglova · 2020 · Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2020)

  This short paper explores how blind and low-vision visual artists perceive and interpret visual information, with the goal of informing the design of a haptic device that could communicate rich visual details. While existing assistive technologies focus on task-oriented visual…
