• 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…

• Transcribing Across the Senses: Community Efforts to Create 3D Printable Accessible Tactile Pictures for Young Children with Visual Impairments

  Abigale Stangl, Chia-Lo Hsu, Tom Yeh · 2015 · ASSETS '15: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This formative study investigates how different stakeholder communities approach designing 3D printable accessible tactile pictures (3DP-ATPs) for young children with visual impairments. While 3D printing offers potential to democratize tactile material production—traditionally…

• 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…
