• Improving Mealtime Experiences of People with Visual Impairments

  SeungA Chung, Soobin Park, Sohyeon Park, Kyungyeon Lee, Uran Oh · 2021 · Proceedings of the 18th International Web for All Conference (W4A)

  This paper investigates the mealtime challenges faced by people with visual impairments (PVI) and explores how assistive technology can support more independent dining experiences. While most accessibility research for PVI has focused on navigation and object recognition, this…

• Slidecho: Flexible Non-Visual Exploration of Presentation Videos

  Yi-Hao Peng, Jeffrey P Bigham, Amy Pavel · 2021 · Proceedings of the 23rd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '21)

  This paper presents Slidecho, a system that makes recorded presentation videos accessible to blind and visually impaired learners by automatically extracting slide content and synchronizing it with the presenter's speech. The core problem is that most presentation videos —…

• Designing Tools for High-Quality Alt Text Authoring

  Kelly Mack, Edward Cutrell, Bongshin Lee, Meredith Ringel Morris · 2021 · Proceedings of the 23rd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '21)

  This paper investigates how to improve the quality of alternative text through better authoring interfaces and feedback mechanisms for automatic alt text, focusing on Microsoft PowerPoint as the application context. The researchers built and tested four prototype interfaces: two…

• Accessing Passersby Proxemic Signals through a Head-Worn Camera: Opportunities and Limitations for the Blind

  Kyungjun Lee, Daisuke Sato, Saki Asakawa, Chieko Asakawa, Hernisa Kacorri · 2021 · Proceedings of the 23rd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '21)

  This paper explores the potential and limitations of using head-worn cameras with computer vision to help blind people access proxemic signals — the spatial behaviour of nearby people that sighted individuals perceive visually, such as someone's presence, distance, relative…

• Going Beyond One-Size-Fits-All Image Descriptions to Satisfy the Information Wants of People Who are Blind or Have Low Vision

  Abigale Stangl, Nitin Verma, Kenneth R. Fleischmann, Meredith Ringel Morris, Danna Gurari · 2021 · ASSETS '21: The 23rd International ACM SIGACCESS Conference on Computers and Accessibility

  Current image description practices typically produce a single, one-size-fits-all description for each image, yet the same image can appear across vastly different contexts — news websites, e-commerce platforms, social media feeds, travel sites, and personal photo libraries —…

• Deep Learning Methods for Sign Language Translation

  Tejaswini Ananthanarayana, Priyanshu Srivastava, Akash Chintha, Akhil Santha, Brian Landy, Joseph Panaro, Andre Webster, Nikunj Kotecha, Shagan Sah, Thomastine Sarchet, Raymond Ptucha, Ifeoma Nwogu · 2021 · ACM Transactions on Accessible Computing

  This comprehensive study evaluates deep learning methods for translating sign language video directly to spoken/written text—critically, without requiring the intermediate step of gloss-based recognition (manual sign-for-sign transcription). The researchers systematically…

• Iterative Design of Sonification Techniques to Support People with Visual Impairments in Obstacle Avoidance

  Giorgio Presti, Dragan Ahmetovic, Mattia Ducci, Cristian Bernareggi, Luca A. Ludovico, Adriano Baratè, Federico Avanzini, Sergio Mascetti · 2021 · ACM Transactions on Accessible Computing

  This paper presents WatchOut, a sonification system that conveys real-time obstacle information to blind or visually impaired (BVI) people through non-verbal audio cues. While white canes detect obstacles only within about 1 meter and miss elevated hazards, computer vision on…

• Effect of Sign-recognition Performance on the Usability of Sign-language Dictionary Search

  Saad Hassan, Oliver Alonzo, Abraham Glasser, Matt Huenerfauth · 2021 · ACM Transactions on Accessible Computing

  This paper investigates how the performance of sign-language recognition technology affects user satisfaction with ASL dictionary search systems. Unlike written languages where users can type unfamiliar words to look them up, ASL learners who encounter an unfamiliar sign cannot…

• Screen Parsing: Towards Reverse Engineering of UI Models from Screenshots

  Jason Wu, Xiaoyi Zhang, Jeff Nichols, Jeffrey P. Bigham · 2021 · The 34th Annual ACM Symposium on User Interface Software and Technology (UIST)

  This paper introduces screen parsing, the task of predicting UI elements and their hierarchical relationships from a screenshot alone. While prior work could detect individual UI elements on a screen (element detection), those approaches produced flat lists of elements with no…

• Screen Recognition: Creating Accessibility Metadata for Mobile Applications from Pixels

  Xiaoyi Zhang, Lilian de Greef, Amanda Swearngin, Samuel White, Kyle Murray, Lisa Yu, Qi Shan, Jeffrey Nichols, Jason Wu, Chris Fleizach, Aaron Everitt, Jeffrey P. Bigham · 2021 · CHI Conference on Human Factors in Computing Systems

  This paper from Apple introduces Screen Recognition, a system that automatically generates accessibility metadata for mobile apps by analyzing their visual pixels, enabling screen readers to work with apps that lack proper developer-provided accessibility information. The…
