Dasher - a Data Entry Interface
Using Continuous Gestures and Language
David J Ward, Alan F Blackwell and David J C MacKay
Existing devices for communicating information to computers are bulky, slow to use, or unreliable. Dasher is a new interface
incorporating language modelling and driven by continuous two-dimensional gestures, e.g. a mouse, touchscreen, or eye-tracker. Tests
have shown that this device can be used to enter text at around 34 words per minute, compared with typical ten-finger keyboard typing
of 40 - 60 words per minute.
Although the interface is slower than a conventional keyboard, it is small and simple, and could be used on personal data assistants
and by motionally-impaired computer users.
