Abstract
It has recently been demonstrated how techniques of
non-deterministic structural modelling can be applied to reduce the number
of keystrokes typed by a user in typical interactive computer sessions. The
sequence of keystrokes is observed by the machine, modelled, and where
possible used to form predictions of the characters about to be typed.
This paper discusses the application of such an interface to the
physically handicapped. Particular attention is paid to reducing the
number of keystrokes needed to enter different kinds of text, such as
source programs, interactive commands, and plain English. In some
cases up to 50% of a users keystrokes are correctly predicted, resulting
in significant keystroke count reductions.
