• Pushing the Raman principle

  Clayton Lewis · 2013 · Proceedings of the 10th International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper explores the implications of what the author calls the "Raman Principle," attributed to T.V. Raman: "The way to think about the visual system is as a way to answer queries against a spatial database. If you have an alternate way to ask the queries and get the answers,…

• Using simultaneous audio sources to speed-up blind people's web scanning

  João Guerreiro · 2013 · Proceedings of the 10th International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This doctoral consortium paper proposes using multiple simultaneous audio sources to help blind users scan web content faster. The core problem is that screen readers present information sequentially — one item at a time — while sighted users can visually scan an entire page at…

• Adapting data table to improve web accessibility

  Pauli P. Y. Lai · 2013 · Proceedings of the 10th International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper addresses the challenge of making web data tables accessible to screen reader users, particularly when tables are not properly marked up with semantic HTML tags like <th>, <thead>, and <tfoot>. Screen readers present content linearly, so large tables become…

• A Mobile Interactive Maps Application for a Visually Impaired Audience

  Nikolaos Kaklanis, Konstantinos Votis, Dimitrios Tzovaras · 2013 · Proceedings of the 10th International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This demo paper presents "Open Touch/Sound Maps," an Android mobile application that makes interactive maps accessible to visually impaired and blind users through multimodal feedback. Web-based spatial information resources like OpenStreetMap are inherently visual, leaving…

• Towards the Usage of Pauses in Audio-Described Videos

  Benoît Encelle, Magali Ollagnier Beldame, Yannick Prié · 2013 · Proceedings of the 10th International Cross-Disciplinary Conference on Web Accessibility (W4A)

  This paper explores the use of "artificial pauses" — brief interruptions inserted into video playback — as a technique for delivering audio descriptions that cannot fit within the natural gaps in a video's soundtrack. Classical audio description is constrained by the duration of…

• Eyes-Free Yoga: An Exergame Using Depth Cameras for Blind & Low Vision Exercise

  Kyle Rector, Cynthia L. Bennett, Julie A. Kientz · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper presents Eyes-Free Yoga, an exergame built on the Microsoft Kinect that teaches six yoga poses to people who are blind or low vision using entirely auditory feedback. Research shows that people with visual impairments are more likely to be obese and less physically…

• Improving Public Transit Accessibility for Blind Riders by Crowdsourcing Bus Stop Landmark Locations with Google Street View

  Kotaro Hara, Shiri Azenkot, Megan Campbell, Cynthia L. Bennett, Vicki Le, Sean Pannella, Robert Moore, Kelly Minckler, Rochelle H. Ng, Jon E. Froehlich · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper introduces Bus Stop CSI (Crowdsourcing Streetview Inspections), a scalable method for collecting bus stop location and landmark descriptions by combining online crowdsourcing with Google Street View (GSV). Blind and low-vision bus riders rely heavily on physical…

• Uncovering Information Needs for Independent Spatial Learning for Users Who Are Visually Impaired

  Nikola Banovic, Rachel L. Franz, Khai N. Truong, Jennifer Mankoff, Anind K. Dey · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper presents two studies examining how visually impaired individuals learn about their environments and build cognitive maps — the mental representations of spatial relationships that sighted people largely construct through casual visual observation. Study 1 involved…

• Exploring the Use of Speech Input by Blind People on Mobile Devices

  Shiri Azenkot, Nicole B. Lee · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper investigates how blind people use speech input on mobile devices through two studies: a survey of 169 participants (64 blind/low-vision, 105 sighted) and a laboratory study with 8 blind participants composing paragraphs on an iPod Touch using speech dictation versus…

• "Pray Before You Step Out": Describing Personal and Situational Blind Navigation Behaviors

  Michele A. Williams, Amy Hurst, Shaun K. Kane · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper presents a formative study exploring how 30 adults with vision impairments use technology and personal strategies to navigate both indoor and outdoor environments. Rather than introducing new navigation technology, the research aims to build a richer understanding of…

• Interviewing Blind Photographers: Design Insights for a Smartphone Application

  Dustin Adams, Tory Gallagher, Alexander Ambard, Sri Kurniawan · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This short paper reports on interviews with 11 people with limited to no vision who take digital photographs independently, investigating how they take, store, organize, and share their photos. While prior research had addressed camera aiming assistance for blind photographers…

• Bypassing Lists: Accelerating Screen-Reader Fact-Finding with Guided Tours

  Tao Yang, Prathik Gadde, Robert Morse, Davide Bolchini · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper investigates whether guided tours — a navigation pattern that linearly links content pages with next/previous controls — can help screen-reader users perform fact-finding tasks more efficiently than traditional index-based navigation, particularly when the index lacks…
