• 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…

• Linked Data-Driven Decision Support for Accessible Travelling

  Chaohai Ding, Mike Wald, Gary Wills · 2015 · Proceedings of the 12th International Web for All Conference (W4A)

  This doctoral consortium paper proposes using Linked Data principles to build a decision support system (DSS) for accessible travel planning, primarily targeting people with mobility difficulties. The core problem is that accessibility information about physical places — ramps,…

• TactileMaps.net: A Web Interface for Generating Customized 3D-Printable Tactile Maps

  Brandon T. Taylor, Anind K. Dey, Dan P. Siewiorek, Asim Smailagic · 2015 · ASSETS '15: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This demonstration paper presents TactileMaps.net, a web-based tool that enables visually impaired users to independently generate customized 3D-printable tactile maps. Tactile maps are valuable tools for helping blind individuals understand their environment, but traditionally…

• 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…

• Exploring Interface Design for Independent Navigation by People with Visual Impairments

  Erin L. Brady, Daisuke Sato, Chengxiong Ruan, Hironobu Takagi, Chieko Asakawa · 2015 · ASSETS 2015: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This short poster paper from ASSETS 2015 explores how people with visual impairments respond to different navigation interface designs during in situ walking tasks. The authors observe that prior research has been limited in two ways: user studies of navigation applications are…
