• Real Time Object Scanning Using a Mobile Phone and Cloud-based Visual Search Engine

  Yu Zhong, Pierre J. Garrigues, Jeffrey P. Bigham · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2013)

  This paper presents Scan Search, an iPhone application that enables blind users to identify everyday objects in real time by continuously scanning with their phone camera rather than taking individual photos. The core challenge addressed is that blind people struggle with the…

• Investigating the Appropriateness of Social Network Question Asking as a Resource for Blind Users

  Erin L. Brady, Yu Zhong, Meredith Ringel Morris, Jeffrey P. Bigham · 2013 · Proceedings of the 2013 Conference on Computer Supported Cooperative Work (CSCW 2013)

  This paper explores whether social networking sites (SNSs) are a viable alternative to paid crowdsourcing for answering blind users' visual questions. The research combines three methods: a survey of 191 blind adults about their social networking habits and attitudes toward…

• Visual Challenges in the Everyday Lives of Blind People

  Erin Brady, Meredith Ringel Morris, Yu Zhong, Samuel White, Jeffrey P. Bigham · 2013 · CHI '13: Proceedings of the SIGCHI Conference on Human Factors in Computing Systems

  This paper presents the findings of a year-long large-scale study of VizWiz Social, an iPhone application that allows blind users to take a photograph, record a spoken question about it, and receive answers from crowd workers or social contacts within about a minute. Between May…

• Designing an Accessible Clothing Tag System for People with Vision Impairments

  Michele A. Williams, Kathryn Ringland, Amy Hurst · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '13)

  This short paper explores the design of accessible clothing identification systems for people with vision impairments. The authors note that many clothing characteristics — color, pattern, fabric type, care instructions — are inherently visual and therefore inaccessible. People…

• Comparison of Reading Accuracy between Tactile Pie Charts and Tactile Band Charts

  Kosuke Araki, Tetsuya Watanabe · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '13)

  This short paper compares the accuracy and efficiency of reading tactile pie charts versus tactile band charts for determining proportional data through touch. The authors are developing software that automatically generates tactile charts from CSV data and needed to determine…

• Uncovering the Role of Expectations on Perceived Web Accessibility

  Amaia Aizpurua, Myriam Arrue, Markel Vigo · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '13)

  This short paper investigates how user expectations shape the perception of web accessibility for blind users, arguing that guideline compliance alone does not guarantee a satisfying user experience. The authors note a key gap: prior research found that only 50.4% of problems…

• Auditory Displays for Accessible Fantasy Sports

  Jared M. Batterman, Jonathan H. Schuett, Bruce N. Walker · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '13)

  This short paper addresses the inaccessibility of online fantasy sports platforms for visually impaired users and presents an accessible fantasy football system built around auditory display techniques. Fantasy sports are a major social and recreational activity with over 32…

• Follow That Sound: Using Sonification and Corrective Verbal Feedback to Teach Touchscreen Gestures

  Uran Oh, Shaun K. Kane, Leah Findlater · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '13)

  This paper proposes and evaluates two techniques for teaching touchscreen gestures to users with visual impairments: gesture sonification (mapping finger position to audio using pitch for the y-axis and stereo panning for the x-axis) and corrective verbal feedback…

• Touchplates: Low-Cost Tactile Overlays for Visually Impaired Touch Screen Users

  Shaun K. Kane, Meredith Ringel Morris, Jacob O. Wobbrock · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '13)

  This paper introduces touchplates — inexpensive, unpowered, customizable tactile overlays that can be placed on touch screens to provide physical guides and tactile feedback for blind and visually impaired users. Unlike prior approaches that either offered limited functionality…

• UbiBraille: Designing and Evaluating a Vibrotactile Braille-Reading Device

  Hugo Nicolau, João Guerreiro, Tiago Guerreiro, Luís Carriço · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '13)

  This paper presents UbiBraille, a wearable vibrotactile device that enables blind users to read textual information privately and inconspicuously by leveraging their existing knowledge of Braille. The device consists of six small vibration motors attached to adjustable aluminum…

• Do You See What I See? Designing a Sensory Substitution Device to Access Non-Verbal Modes of Communication

  M. Iftekhar Tanveer, A. S. M. Iftekhar Anam, Mohammed Yeasin, Majid Khan · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '13)

  This paper presents iFEPS (improved Facial Expression Perception through Sound), a visual-to-auditory sensory substitution device that enables blind users to perceive their conversation partner's facial expressions through audio feedback. Research suggests that 80% of…
