• Analyzing Visual Questions from Visually Impaired Users

  Erin L. Brady · 2011 · The Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This doctoral consortium paper presents an analysis of the types of visual questions that visually impaired users ask through VizWiz, a mobile phone application that provides near-realtime answers to visual questions. VizWiz allows users to take a photo with their phone, speak a…

• Situation-based Indoor Wayfinding System for the Visually Impaired

  Eunjeong Ko, Jin Sun Ju, Eun Yi Kim · 2011 · The Proceedings of the 13th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper presents an indoor wayfinding system for visually impaired people that uses situation-aware color codes affixed to building walls to guide users to destinations in unfamiliar environments. The key innovation is a situation-based approach: rather than providing all…
