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…

Environmental Factors in Indoor Navigation Based on Real-World Trajectories of Blind Users
This paper addresses a methodological blind spot in blind-navigation research: studies typically report localization accuracy and completion time, but say almost nothing about how the physical environment itself shapes where users go wrong. The autho…

Variability in Reactions to Instructional Guidance during Smartphone-Based Assisted Navigation of Blind Users
This paper takes a close, sensor-level look at something most indoor-navigation research glosses over: how differently individual blind users actually react to the same spoken instruction. The authors instrumented a smartphone-and-BLE-beacon turn-by-…

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 …

ReCog: Supporting Blind People in Recognizing Personal Objects
ReCog is a smartphone application designed to help blind users recognize their own personal objects — items like specific clothing, handmade goods, medicines, or family photos that cannot be identified by general-purpose recognizers such as Seeing AI…

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…

Eyes on the Palm: Investigating a Ring-Shaped Camera for Seamless Accessible Tactile Exploration
Tsutsui and colleagues ask how the form factor of a camera-based assistive device shapes the way blind and low-vision (BLV) users coordinate their hands during tactile exploration of real museum exhibits. Smartphone apps such as Seeing AI and Be My A…

Barrier pointing: using physical edges to assist target acquisition on mobile device touch screens
Froehlich, Wobbrock and Kane propose barrier pointing: a set of stylus-based target acquisition techniques that exploit the raised physical edge of a mobile touch screen to stabilise input for users with motor impairments. Standard touch-screen tappi…
