Dasher - a Data Entry Interface
Using Continuous Gestures and Language
Models
- by 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 25 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
handicapped computer users.
