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 …

Autonomous Navigation through the City for the Blind
This paper presents a study on the use of an audio-based GPS navigation application designed to help blind people navigate independently through urban environments. The software, developed for PocketPC devices with Bluetooth GPS receivers, uses a clo…

Smartphone Application for Indoor Scene Localization
This demonstration paper presents a smartphone-based assistive technology that uses computer vision to determine a blind user's location inside a building where GPS is ineffective. The system operates on a client-server model running on an Android HT…

Non-Visual-Cueing-Based Sensing and Understanding of Nearby Entities in Aided Navigation
This demonstration paper presents a context-aware navigation aid system for blind individuals that combines three levels of assistance to enhance understanding of the surrounding environment. The system addresses a fundamental challenge: blind people…

Headlock: A Wearable Navigation Aid that Helps Blind Cane Users Traverse Large Open Spaces
This demo paper presents HEADLOCK, a navigation aid built for an optical head-mounted display (HMD) that helps blind cane users traverse large open spaces — environments like building foyers, plazas, and parking lots that lack the tactile boundaries …

Where's My Bus Stop? Supporting Independence of Blind Transit Riders with StopInfo
This paper presents StopInfo, a system integrated into the OneBusAway transit app that provides detailed information about bus stops to help blind and low vision riders locate and verify stops, particularly in unfamiliar areas. Locating a bus stop is…

"Just Let the Cane Hit It": How the Blind and Sighted See Navigation Differently
This paper reveals fundamental mismatches between how blind and sighted people understand pedestrian navigation, drawing on over a year of immersive qualitative research including focus groups, diary studies, and partner observations. The researchers…

Route Descriptions, Spatial Knowledge and Spatial Representations of Blind and Partially Sighted People: Improved Design of Electronic Travel Aids
This paper presents a qualitative study investigating how blind and partially sighted people acquire spatial knowledge, form mental maps, and describe routes—with the goal of informing better design of electronic travel aids (ETAs). The researchers w…
