ABSTRACT
Interfaces which support natural inputs such as hand-
writing and speech are becoming more prevalent and
this is a desirable trend. However, these recognition-
based interface techniques are error prone. Despite re-
search e orts to improve recognition rates, a certain
amount of error will never be removed. Suitable re-
search e orts should attend to the problem of correc-
tion techniques for these error prone techniques. Hu-
mans have developed countless ways to correct errors
in understanding or clarify ambiguous statements. It is
timefor interface designers to focus on ways for comput-
ers to do the same. We present a survey of the design,
