ABSTRACT
We present a new system, called Cirrin, for pen input of
ASCII characters using word-level unistrokes. Our system
addresses the tradeoff between speed and accuracy of pen-
based text entry by substituting precision on the part of the
user for ease of recognitionon the part of the computer. Cirrin

Pen input of ASCII text is becoming a mainstream technol-
