The Present and Future of Museum Accessibility for People with Visual Impairments
This short ASSETS '18 poster paper is the formative survey that motivated much of the later Miraikan and CaBot museum-accessibility work from the same research group. The authors conducted in-person semi-structured interviews with 19 people with visu…

BlindPilot: A Robotic Local Navigation System that Leads Blind People to a Landmark Object
Most indoor-navigation research for blind travellers has focused on what the authors call 'global' navigation — getting from a building entrance to a room, gate, or exhibit. The 'last few metres' of the journey, a body-scale interaction with a specif…

Smartphone-Based Assistance for Blind People to Stand in Lines
This CHI 2020 Late-Breaking Work is the preliminary study that seeded the CHI 2021 LineChaser paper by the same research group. Where the fuller LineChaser system would later combine line-end finding with AR-marker-based localisation and a dual audio…

PathFinder: Designing a Map-less Navigation System for Blind People in Unfamiliar Buildings
Map-based indoor navigation systems for blind travellers (CaBot, NavCog, BLE-beacon apps) work well when a prebuilt map exists, but building and maintaining those maps is labour-intensive and has only been done for a tiny fraction of the world's buil…

Guiding Blind Pedestrians in Public Spaces by Understanding Walking Behavior of Nearby Pedestrians
Collisions with other pedestrians are one of the most common hazards for blind travellers in public space — 87.8% of blind people report colliding or nearly colliding with pedestrians, bicycles, or obstacles. White canes detect contact rather than ap…

LineChaser: A Smartphone-Based Navigation System for Blind People to Stand in Lines
Standing in line is a mundane-looking task — at a cashier, bus stop, or airport check-in — but for a blind person it is a brittle, anxiety-ridden sequence: find where the line currently ends (a position that moves), join it without bumping into anyon…

Corridor-Walker: Mobile Indoor Walking Assistance for Blind People to Avoid Obstacles and Recognize Intersections
Walking an indoor corridor independently is deceptively hard for a blind traveller. Two problems compound: avoiding obstacles stacked against the wall (the same wall the traveller uses as a tactile guide) and recognising when an intersection has arri…

Pedestrian Detection with Wearable Cameras for the Blind: A Two-way Perspective
Wearable cameras — embedded in commercial products like OrCam, Aira, and eSight — promise blind users equitable access to visual information about the people around them: who is approaching, where they are looking, whether eye contact is possible. Bu…

Enhancing Blind Visitor's Autonomy in a Science Museum Using an Autonomous Navigation Robot
Museums have historically struggled to offer blind visitors the same self-directed, exploratory experience that sighted visitors take for granted. Prior solutions — tactile tours, audio guides, or pre-fixed navigation routes — either require a human …

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…
