SceneScout: Towards AI-Driven Access to Street Level Imagery for Blind Users
Jain, Findlater and Gleason present SceneScout, a prototype web interface that uses a multimodal large language model (GPT-4o) to make street level imagery — the panoramic pedestrian-height photography behind Apple Maps Look Around and Google Street …

Resilience to Disruption: Accessible Navigation for People with Visual Impairment
This paper investigates how people with visual impairments (PwVI) actually navigate urban environments, especially during severe weather events such as snowstorms, high winds, and icy conditions, and how digital navigation technologies do or do not s…

Analysis of Navigability of Web Applications for Improving Blind Usability
This TOCHI article is a two-study investigation into why modern web applications — especially visually dense online shopping sites — remain slow and frustrating for blind users even when they pass automated accessibility checks. The authors argue tha…

On the Audio Representation of Radial Direction
This paper proposes a new primitive for auditory displays — radial direction — and evaluates a concrete mapping of vowel-like sounds to eight cardinal and ordinal directions. The authors observe that almost all prior sonification work has mapped data…

Field Trials of Autonomous Navigation Robot for Visually Impaired People
This paper reports field trials of AI Suitcase, an autonomous navigation robot shaped like a conventional carry-on suitcase and designed to guide blind and visually impaired (BVI) travellers safely through unfamiliar public spaces. The system traces …

Robot-Assisted Group Tours for Blind People
Hu and colleagues investigate how an assistive mobile robot can support blind people's participation in mixed-visual group tours, where blind and sighted visitors share the same guided experience. The motivation is that group activities are central t…

How Does Delegation in Social Interaction Evolve Over Time? Navigation with a Robot for Blind People
Hata and colleagues run a three-week longitudinal study of how six blind participants delegate social navigation tasks to a guide robot in the Miraikan science museum. The paper pushes back against the default assumption that accessible navigation ro…

Accessible spaces: navigating through a marked environment with a camera phone
This short Assets '07 demonstration paper from UC Santa Cruz and the Smith-Kettlewell Eye Research Institute describes a camera-phone-based wayfinding system for blind travellers. The core idea is to deploy small, cheap, pie-shaped colour markers in …

A Novel Wayfinding System Based on Geo-coded QR Codes for Individuals with Cognitive Impairments
This paper presents a wayfinding prototype system that uses geo-coded QR codes placed at decision points along routes to provide just-in-time navigation directions to people with cognitive impairments. Developed by researchers at Chung Yuan Christian…

A Software Model to Support Collaborative Mathematical Work between Braille and Sighted Users
This paper presents the software model behind the MaWEn (Mathematical Working Environment) project, a long-term collaboration between Johannes Kepler Universität Linz and Université Pierre et Marie Curie in Paris. The project addresses a fundamental …
