Evaluating a Pen-based Computer Interface for Novice Older Users
This short paper from the University of Oaxaca in Mexico proposes and evaluates a simplified pen-based gesture interface designed for novice older computer users who struggle with the traditional WIMP (Windows, Icons, Menus, and Pointers) paradigm. T…

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…

Human Factors Issues in the Neural Signals Direct Brain-Computer Interface
This paper presents the software and human factors aspects of the Neural Signals direct brain-computer interface project — one of the first implanted BCI systems tested in humans. Unlike non-invasive BCIs that read EEG signals through the scalp, this…

Programming by Voice, VocalProgramming
This paper presents VocalProgrammer, a system designed to enable programming entirely by voice, motivated primarily by the high incidence of repetitive stress injuries (RSI) among programmers. The authors note that the total cost of RSI of all types …
