Capt. Disappointment writes "This story on Slashdot talks about a new input system called Dasher. Here's a link to the Dasher homepage. Here's a three-page explanation. Here's a list of demonstrations" Dasher is a data entry interface that uses language modelling to recognize text from continuous two-dimensional gestures, e.g. a mouse, a stylus, or eye-tracker. Tests have shown that, after an hour of practice, novice users reach a writing speed of about 20 words per minute while taking dictation. Experienced users achieve writing speeds of about 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 simple to use, and could be used on personal data assistants and by motion-impaired computer users. Dasher can readily be used to enter text from any alphabet. Here are some screenshots, and it can be downloaded for use on Windows, Pocket PC, and Linux.
