Existing devices for communicating information to computers are bulky, slow, or unreliable. Dasher is an interface incorporating language modeling and driven by continuous two-dimensional gestures (e.g., a mouse, a stylus, or eye-tracker). Tests have shown that, after 1 hr of practice, novice users reach a writing speed of about 20 words per minute (wpm) while taking dictation. Experienced users achieve writing speeds of about 34 wpm, compared with typical 10-finger keyboard typing of 40 to 60 wpm. 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.
