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 …

Multimodal Trajectory Playback for Teaching Shape Information and Trajectories to Visually Impaired Computer Users
This research investigates how haptic (force-feedback) and audio trajectory playback can teach shapes and gestures to blind and visually impaired computer users. The fundamental challenge addressed is that spatial information—shapes, diagrams, graphs…

Spindex (Speech Index) Improves Auditory Menu Acceptance and Navigation Performance
This paper introduces the "spindex" (speech index), a novel auditory cue designed to improve navigation through spoken menus on mobile devices. The spindex works by pronouncing the first letter of each menu item before the full text-to-speech (TTS) r…

Universal Design of Auditory Graphs: A Comparison of Sonification Mappings for Visually Impaired and Sighted Listeners
This study investigates whether auditory graphs—using sound to represent data for people who cannot see visual graphs—can be designed universally for both sighted and visually impaired users, or whether different sonification mappings are needed for …
