Abstract:
Because of its promise of natural interaction, recognition is coming into
its own as a mainstream technology for use with computers. Both
commercial and research applications are beginning to use it
extensively. However the errors made by recognizers can be quite costly,
and this is increasingly becoming a focus for researchers. We present a
survey of existing error correction techniques in the user interface.
These mediation techniques most commonly fall into one of two
strategies, repetition and choice. Based on the needs uncovered by this
survey, we have developed OOPS, a toolkit that supports resolution of
input ambiguity through mediation. This paper describes four new
interaction techniques built using OOPS, and the toolkit mechanisms
required to build them. These interaction techniques each address
problems not directly handled by standard approaches to mediation, and
can all be re-used in a variety of settings.
