Exploring Interface Design for Independent Navigation by People with Visual Impairments
This short poster paper from ASSETS 2015 explores how people with visual impairments respond to different navigation interface designs during in situ walking tasks. The authors observe that prior research has been limited in two ways: user studies of…

NavCog: A Navigational Cognitive Assistant for the Blind
This paper introduces NavCog, an iPhone-based turn-by-turn navigation assistant designed to guide blind users through unfamiliar indoor and outdoor environments without requiring expensive infrastructure or structural modifications. The authors argue…

BBeep: A Sonic Collision Avoidance System for Blind Travellers and Nearby Pedestrians
This paper presents BBeep, an assistive suitcase-shaped system designed to help blind travellers navigate crowded public spaces such as international airports, train stations, and shopping malls. The authors argue that existing blind-navigation resea…

Modeling Expertise in Assistive Navigation Interfaces for Blind People
This short IUI paper asks a question most assistive-navigation research leaves unasked: what happens as a blind user becomes an expert on a route? Existing smartphone guidance apps deliver the same instruction set on a user's tenth trip down a corrid…

Airport Accessibility and Navigation Assistance for People with Visual Impairments
This paper investigates whether a BLE-beacon-based smartphone navigation system can enable visually impaired travelers to move through an airport independently — a setting where they are currently required to rely on airline-provided sighted escorts …

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…
