• Application for the configuration and adaptation of the Android operating system for the visually impaired

  Bruna de Oliveira, Juliana Cristina Braga, Rafael J. Pezzuto Damaceno · 2018 · Proceedings of the 15th International Web for All Conference (W4A 2018)

  This short paper presents the design and preliminary evaluation of an Android application that allows people with visual impairments (PVI) to configure their device’s accessibility settings using voice commands, bypassing the paradoxical problem that activating accessibility…

• A TensorFlow-based Assistive Technology System for Users with Visual Impairments

  Davide Mulfari · 2018 · Proceedings of the 15th International Web for All Conference (W4A 2018)

  This extended abstract presents a wearable computer vision system that uses deep learning to classify objects in a blind user’s surroundings and provide audio descriptions via text-to-speech. The system addresses a limitation of smartphone-based object recognition apps: people…

• Home Automation for an Independent Living: Investigating the Needs of Visually Impaired People

  Barbara Leporini, Marina Buzzi · 2018 · Proceedings of the 15th International Web for All Conference (W4A 2018)

  This paper investigates the habits, expectations, and unmet needs of visually impaired people regarding home automation and remote control systems through an online survey of 42 participants (32 totally blind, 10 low vision; ages 18-70+; 64.3% male) and face-to-face interviews…

• Exploring Aural Navigation by Screenless Access

  Mikaylah Gross, Joe Dara, Christopher Meyer, Davide Bolchini · 2018 · Proceedings of the 15th International Web for All Conference (W4A 2018)

  This paper introduces screenless access, a paradigm for browsing aural information architectures using one-handed, in-air gestures recognised by an off-the-shelf Myo armband, freeing blind and visually impaired users from the constraint of holding and touching a smartphone…

• How Context and User Behavior Affect Indoor Navigation Assistance for Blind People

  João Guerreiro, Eshed Ohn-Bar, Dragan Ahmetovic, Kris Kitani, Chieko Asakawa · 2018 · Proceedings of the 15th International Web for All Conference (W4A 2018)

  This short paper presents a fine-grained thematic analysis of user behaviour during indoor assisted navigation to understand when and why navigation errors occur even when the underlying localisation system is accurate. The research uses NavCog, a smartphone-based indoor…

• 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…
