Dasher

Dasher

Dasher is an open source information-efficient text-entry interface, driven by natural continuous pointing gestures.

Dasher is a zooming predictive text entry system designed for situations where keyboard input is not practical (for accessibility reasons, on a palmtop or wearable computer, when operating a computer one-handed, by joystick, touchscreen, trackball, mouse or when operating a computer with no hands (i.e. by head-mouse or by eyetracker).

The eyetracking version of Dasher allows an experienced user to write text as fast as normal handwriting - 25 words per minute; using a mouse, experienced users can write at 39 words per minute.

Dasher uses a more advanced prediction algorithm than the T9 system often used in mobile phones, making it sensitive to surrounding context.

Dasher is designed to help people with physical difficulties and therefore this is where it is most accessible.
