ABSTRACT
We present various adaptations of the EdgeWrite unistroke text entry method that work on multiple computer input devices: styluses, touchpads, displacement and isometric joysticks, four keys or buttons, and trackballs. We argue that consistent, flexible, multi-device input is important to both accessibility and to ubiquitous computing. For accessibility, multi-device input means users can switch among devices, distributing strain and fatigue among different muscle groups. For ubiquity, it means users can "learn once, write anywhere," even as new devices emerge. By considering the accessibility and ubiquity of input techniques, we can design for both motor-impaired users and "situationally impaired" able-bodied users who are on-the-go. We discuss the requirements for such input and the challenges of multi-device text entry, such as solving the segmentation problem. This paper accompanies a demonstration of EdgeWrite on multiple devices.

Integrating isometric joysticks into mobile phones for text entry
CHI EA '06: CHI '06 Extended Abstracts on Human Factors in Computing SystemsWe are investigating a new gestural text entry method for mobile phones that uses an isometric joystick and therefore consumes very little physical space. We have created a high-fidelity mobile phone prototype with two embedded isometric joysticks, one ...
In-stroke word completion
UIST '06: Proceedings of the 19th annual ACM symposium on User interface software and technologyWe present the design and implementation of a word-level stroking system called Fisch, which is intended to improve the speed of character-level unistrokes. Importantly, Fisch does not alter the way in which character-level unistrokes are made, but ...
Trackball text entry for people with motor impairments
CHI '06: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsWe present a new gestural text entry method for trackballs. The method uses the mouse cursor and relies on crossing instead of pointing. A user writes in fluid Roman-like unistrokes by ""pulsing"" the trackball in desired letter patterns. We examine ...
