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…

Ad-Hoc Access to Musical Sound for Deaf Individuals
This poster paper presents MuSS-Bits (Music Sensory Substitution Bits), a wearable sensor-display system that enables deaf individuals to explore musical sound from various audio sources with real-time vibrotactile feedback. While existing sensory su…

Comparing Tactile, Auditory, and Visual Assembly Error-Feedback for Workers with Cognitive Impairments
This paper compares three modalities of error feedback — tactile, auditory, and visual — for cognitively impaired workers performing manual assembly tasks at sheltered work organizations. Industrial manufacturing companies increasingly outsource asse…

Using Dynamic Audio Feedback to Support Peripersonal Reaching in Young Visually Impaired People
This paper investigates whether dynamic audio feedback — sound that changes based on the proximity between a reaching hand and target objects — can improve the accuracy of peripersonal reaching (reaching within arm's length) for blind and visually im…

Tactile Accessibility: Does Anyone Need a Haptic Glove?
This paper presents FeelX, a low-cost haptic glove system designed to enable blind users to tactilely explore graphical user interfaces (GUIs) by moving their hands on any flat surface such as a desk or table. The fundamental problem addressed is tha…

FluxMarker: Enhancing Tactile Graphics with Dynamic Tactile Markers
This paper presents FluxMarker, an inexpensive and scalable system that adds dynamic, movable tactile markers on top of static raised-line tactile graphics. Traditional embossed tactile graphics are static and cannot represent changing data, while ex…

Speed-Dial: A Surrogate Mouse for Non-Visual Web Browsing
This paper presents Speed-Dial, a system that uses an off-the-shelf Microsoft Surface Dial as a surrogate mouse for non-visual web browsing. The core problem it addresses is the fundamental mismatch between how sighted and blind users interact with t…

DroneNavigator: Using Leashed and Free-Floating Quadcopters to Navigate Visually Impaired Travelers
This paper explores an unconventional approach to navigation assistance for visually impaired travelers: using small, lightweight quadcopters as mobile sound and haptic sources to guide users through indoor environments. While existing navigation sys…

Designing Interactions for 3D Printed Models with Blind People
This paper investigates how blind people explore 3D printed models and what interaction techniques they prefer for interactive 3D printed models (I3Ms) — physical models augmented with sensors that provide audio descriptions when touched. While 3D pr…

What My Eyes Can't See, A Robot Can Show Me: Exploring the Collaboration Between Blind People and Robots
This University of Lisbon and University of São Paulo study explores how assistive robots can go beyond information-giving technologies (like screen readers) by physically collaborating with blind people. The research consists of two studies. Study 1…
