Text Entry from Power Wheelchairs: EdgeWrite for Joysticks and Touchpads
This paper presents two adaptations of EdgeWrite, a gestural text entry method originally designed as a stylus-based unistroke technique for people with tremor, reconfigured for use with power wheelchair joysticks and touchpads. The research addresse…

MEMOS: An Interactive Assistive System for Prospective Memory Deficit Compensation — Architecture and Functionality
This paper presents MEMOS (Mobile Extensible Memory Aid System), a distributed electronic memory aid designed to compensate for prospective memory deficits following brain injury. Prospective memory — the ability to remember future intentions and tas…

Design and Development of an Indoor Navigation and Object Identification System for the Blind
This paper presents a multi-sensor orientation assistant for blind users navigating unknown indoor environments. The system addresses three core problems identified by blind users: determining one's position, determining head direction and movement d…

visiBabble for Reinforcement of Early Vocalization
This paper presents visiBabble, a real-time system that detects syllable-like vocalizations in infant babbling and responds with brightly coloured animations as visual reinforcement. The system targets infants at risk for speech impairments due to co…

Image Pre-Compensation to Facilitate Computer Access for Users with Refractive Errors
This paper presents a novel approach to improving computer access for people with refractive visual errors by pre-compensating displayed images using knowledge of the user's specific optical aberration. The core insight is that the human eye can be m…

Evaluation of a Non-Visual Molecule Browser
This paper evaluates Kekulé, software designed to allow visually impaired users to explore chemical molecular structures — diagrams that are typically presented as two-dimensional graph schematics showing atoms (nodes) connected by bonds (edges). Mol…

Accessibility Designer: Visualizing Usability for the Blind
This paper from IBM's Tokyo Research Laboratory presents Accessibility Designer (aDesigner), a tool that goes beyond conventional accessibility checkers by visualising the usability of web pages for blind screen reader users rather than merely checki…

Mouse Movements of Motion-Impaired Users: A Submovement Analysis
This paper presents a detailed submovement analysis of mouse cursor trajectories from six motion-impaired users (four with cerebral palsy of varying types — athetoid, athetoid with spasm, and general — and one with Friedrich's ataxia and tremor) and …

The Audio Abacus: Representing Numerical Values with Nonspeech Sound for the Visually Impaired
This paper introduces the Audio Abacus, a novel sonification application that transforms exact numerical values into sequences of non-speech tones, following the analogy of a physical abacus where each digit is represented by a distinct sound. Unlike…

Cursor Measures for Motion-Impaired Computer Users
This paper systematically analyses cursor movement patterns of motion-impaired computer users to understand the specific difficulties they face with point-and-click interactions in graphical user interfaces. The authors argue that existing cursor mea…
