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…

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 …

ChitChatGuide: Conversational Interaction Using Large Language Models for Assisting People with Visual Impairments to Explore a Shopping Mall
ChitChatGuide is a smartphone-based indoor navigation system that wraps a GPT-4-powered conversational interface around an existing BLE-beacon localisation stack (HULOP) to support something most blind-navigation research overlooks: casual, purpose-l…

Snap&Nav: Smartphone-based Indoor Navigation System For Blind People via Floor Map Analysis and Intersection Detection
Snap&Nav is a smartphone-based indoor navigation system for blind travellers that works in any building with a visible floor map, without requiring the building owner to pre-build a digital map, install BLE beacons, or deploy any other localisation i…

BentoMuseum: 3D and Layered Interactive Museum Map for Blind Visitors
BentoMuseum proposes a novel museum map format designed to help blind visitors access the multidimensional information of a complex, multi-floor museum before and during a visit. Unlike conventional tactile maps that depict a single floor layout and …

WanderGuide: Indoor Map-less Robotic Guide for Exploration by Blind People
Kuribayashi and colleagues design WanderGuide, a suitcase-shaped robotic guide that supports blind people in recreational, open-ended exploration of indoor environments — wandering, browsing, window-shopping — rather than getting from A to B. The tea…
