Abstract: We present a study of the effect of prolonged use on the way users interact with a multimodal form-filling system. The system accepts spoken input as well as pointing input and provides output both in speech and in graphics. We measured the usability of the system in a pre-test / post-test design and analysed in detail the changes in interaction patterns due to exposure. The study shows that with practice users learn to develop interaction patterns that ensure reliable and efficient interaction, resulting in decreased dialogue duration and more user satisfaction.
