• Feel-It: Personalized Audio-Tactile Web Browsing

  Anatoliy Borodin, Yevgen Borodin, Andrii Soviak, Vikas Ashok, Shirin Disfani, I. V. Ramakrishnan · 2019 · Proceedings of the 16th International Web for All Conference (W4A)

  This demonstration paper presents Feel-It, a hardware-software system for audio-tactile web browsing that enables blind users to explore the two-dimensional spatial layout of web pages through touch. The core problem addressed is that screen readers reduce web pages to a…

• Addressing the Situational Impairments Encountered by Firefighters through the Design of Alerts

  Flynn Wolf, Priyanka Soni, Ravi Kuber, Dianne Pawluk, Brian Turnage · 2019 · Proceedings of the 16th International Web for All Conference (W4A)

  This paper describes a structured multi-step approach to designing multimodal alerts for firefighters who experience severe situationally-induced impairments and disabilities (SIIDs) at fire scenes — thick smoke restricting vision, loud noise from combustion, sirens, and power…

• Revisiting Blind Photography in the Context of Teachable Object Recognizers

  Kyungjun Lee, Jonggi Hong, Simone Pimento, Ebrima Jarjue, Hernisa Kacorri · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper introduces a real-time audio-haptic feedback system to help people with visual impairments frame objects in their smartphone camera when training teachable object recognizers. The challenge is that teachable recognizers — which let users train personalized models to…

• A Tangible Math Game for Visually Impaired Children

  Ana Cristina Pires, Sebastian Marichal, Fernando Gonzalez-Perilli, Ewelina Bakala, Bruno Fleischer, Gustavo Sansone, Tiago Guerreiro · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This demonstration paper presents iCETA, an inclusive interactive system for math learning that enables visually impaired children to autonomously engage with and solve additive composition tasks (addition and subtraction) through tangible interaction. The system was designed…

• Exploring Haptic Colour Identification Aids

  Richard Nguyen, Connor Geddes · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This poster paper presents two novel haptic devices — ColourWrist and ColourVest — designed to help people with Colour Vision Deficiency (CVD) identify colors through tactile feedback. Approximately 8% of males and 0.5% of females have some form of CVD, which creates barriers in…

• A Wearable Input Mechanism for Blind Users of Computers Based on Mental Mapping of Thumb-To-Phalanx Distances

  Yash Naik · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2019)

  This student research abstract presents Mentalitype, a glove-based wearable keyboard designed to provide blind users with an affordable and portable text input mechanism for computer-based tasks. The system maps 32 push-buttons to the phalanges (finger bones) of both hands, with…

• Go That Way: Exploring Supplementary Physical Movements by a Stationary Robot When Providing Navigation Instructions

  Xiang Zhi Tan, Elizabeth J. Carter, Samantha Reig, Aaron Steinfeld · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2019)

  This paper explores how stationary kiosk-type robots might provide navigation instructions to blind people by supplementing verbal directions with physical movements. The work is inspired by a technique used by Orientation and Mobility (O&M) experts called Palm Drawing, in which…

• GraVVITAS 2.0: A Framework For Digital Accessible Content Provision

  Cagatay Goncu, Kim Marriott · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2019)

  This demonstration paper presents GraVVITAS 2.0 (Graphics Viewer using Vibration Interactive Touch and Speech), a framework for making graphical information accessible to people with vision impairments on off-the-shelf mobile devices. The paper argues that while screen readers…

• Leveraging Augmented Reality to Create Apps for People with Visual Disabilities: A Case Study in Indoor Navigation

  Chris Yoon, Ryan Louie, Jeremy Ryan, MinhKhang Vu, Hyegi Bang, William Derksen, Paul Ruvolo · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2019)

  This paper presents Clew, an iOS app that leverages Apple’s ARKit augmented reality framework to help people who are blind or visually impaired (B/VI) navigate indoor environments — a setting where GPS is unreliable (accuracy drops to ~5m+ indoors). Clew uses visual-inertial…

• CaBot: Designing and Evaluating an Autonomous Navigation Robot for Blind People

  João Guerreiro, Daisuke Sato, Saki Asakawa, Huixu Dong, Kris M. Kitani, Chieko Asakawa · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2019)

  This paper presents CaBot (Carry-on roBot), an autonomous suitcase-shaped navigation robot designed to guide blind people to destinations in unfamiliar indoor environments while avoiding obstacles. Unlike smartphone navigation apps that provide turn-by-turn instructions but…
