Automating accessibility: The Dynamic Keyboard

Abstract

People with motor disabilities may need to adjust the configuration of their input devices, but often find this an obscure and difficult process. The Dynamic Keyboard exemplifies a potential solution. It continuously adjusts fundamental keyboard accessibility features to suit the requirements of the current user, based on a keyboard use model. Early field results indicate that users have not chosen to take control of these accessibility features from the Dynamic Keyboard, and that a variety of settings are being used. A more detailed ongoing study suggests that automatic adjustment of the key repeat delay feature is acceptable to users, while the debounce feature may not be appropriate for dynamic adjustment.
