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

  Kotaro Hara, Shiri Azenkot, Megan Campbell, Cynthia L. Bennett, Vicki Le, Sean Pannella, Robert Moore, Kelly Minckler, Rochelle H. Ng, Jon E. Froehlich · 2015 · ACM Transactions on Accessible Computing

  This paper tackles a fundamental challenge in public transit accessibility: helping blind and low-vision riders locate bus stops, which often lack nonvisual markers or consistent landmark placement. The researchers developed Bus Stop CSI (Crowdsourcing Streetview Inspections), a…

• Measuring Text Simplification with the Crowd

  Walter S. Lasecki, Luz Rello, Jeffrey P. Bigham · 2015 · Proceedings of the 12th International Web for All Conference (W4A)

  This paper investigates whether non-expert crowd workers can reliably evaluate the simplicity of English text, addressing a key gap in text simplification research. Text simplification — reducing the lexical and syntactic complexity of sentences while preserving meaning — is…

• Zebra Crossing Spotter: Automatic Population of Spatial Databases for Increased Safety of Blind Travelers

  Dragan Ahmetovic, Roberto Manduchi, James M. Coughlan, Sergio Mascetti · 2015 · ASSETS '15: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This paper presents a computer vision system that automatically detects zebra crosswalks by mining satellite imagery and Google Street View, with the goal of augmenting geographic information systems (GIS) to help blind travelers plan safer routes. Knowing crosswalk locations is…

• The Effects of Automatic Speech Recognition Quality on Human Transcription Latency

  Yashesh Gaur · 2015 · ASSETS '15: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This paper investigates a practical question for accessibility: when does providing automatic speech recognition (ASR) output help human captionists work faster, and when does it slow them down? Converting speech to text is fundamental for making audio content accessible to deaf…

• EnTable: Rewriting Web Data Sets as Accessible Tables

  Steven Gardiner, Anthony Tomasic, John Zimmerman · 2015 · ASSETS '15: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This demonstration paper presents EnTable, a crowdsourcing system that transforms visually complex web data presentations into accessible HTML tables. The problem it addresses is fundamental: modern web designers communicate semantic information through sophisticated CSS and…

• Guiding Novice Web Workers in Making Image Descriptions Using Templates

  Valerie S. Morash, Yue-Ting Siu, Joshua A. Miele, Lucia Hasty, Steven Landau · 2015 · ACM Transactions on Accessible Computing (TACCESS)

  This study compares two approaches for using non-expert crowdworkers to create accessible descriptions of STEM images (charts, graphs, diagrams) for people who are blind or have print-reading disabilities. The researchers tested Free-Response Image Description (FRID), where…

• Gauging Receptiveness to Social Microvolunteering

  Erin Brady, Meredith Ringel Morris, Jeffrey P. Bigham · 2015 · CHI Conference on Human Factors in Computing Systems

  This paper introduces the concept of social microvolunteering — a hybrid of friendsourcing and microvolunteering where volunteers install an application that posts microtasks to their social media feeds, enabling their friends to contribute to causes they care about. The…
