Speech-Based Cursor Control
This paper from UMBC investigates the effectiveness of speech-based cursor control for navigating graphical user interfaces, comparing a standard cursor with a predictive cursor designed to compensate for speech recognition delays. While speech recog…

An Invisible Keyguard
This paper from IBM T.J. Watson Research Center presents OverlapKeys, a software-based alternative to physical keyguards that filters overlap typing errors — instances where two keys are pressed simultaneously when only one was intended. Overlap erro…

Zooming Interfaces! Enhancing the Performance of Eye Controlled Pointing Devices
This paper from De Montfort University quantifies the performance problems of eye-based pointing on standard graphical user interfaces and demonstrates that adding a zoom facility dramatically improves usability. The researchers identified three fund…

Neck Range of Motion and Use of Computer Head Controls
This study from the University of Pittsburgh investigates the relationship between neck range of motion and performance when using computer head controls — devices that translate head movements into cursor movements on screen. The research involved 1…

Evaluation of Scanning User Interfaces Using Real-Time-Data Usage Logs
This paper from Sheffield Hallam University and Barnsley District General Hospital presents a novel approach to evaluating electronic assistive technology (EAT) for people with severe disabilities through automated analysis of real-time usage logs. T…

Towards an EOG-Based Eye Tracker for Computer Control
This paper describes the development of an eye tracking system for computer control based on bio-electrical signals, intended as a pointing device for people with physical disabilities. The system combines two complementary biosignal approaches: the …

Head Pointing and Speech Control as a Hands-Free Interface to Desktop Computing
This paper presents a hands-free computer interface that combines head pointing with speech control to enable users who cannot use a mouse and keyboard to operate standard WIMP-style graphical user interfaces. Developed at the Fraunhofer Institute in…

A Study of Input Device Manipulation Difficulties
This paper from the University of Edinburgh describes a pilot study designed to gather detailed, quantified data about physical input errors made by people with motor disabilities when using standard keyboards and mice. The author identifies a signif…

Enhancing Scanning Input with Non-Speech Sounds
This paper proposes adding structured non-speech sounds (earcons) to scanning input systems used by people with severe motor disabilities who can only operate a single switch. Scanning input works by sequentially highlighting items in a grid; the use…
