The Effects of Experience and Interface
on Users' Behavior in EMMI
Abstract:We describe the motivation for and the design of a new interface for EMMI, including a
"talking head" and greater initiative on the part of the system. We report the results of
experiments in that new setting, comparing the behavior of experienced vs.
inexperienced users, and comparing this new interface with the previous interface. The
experience of the user had no effect on his/her behavior. Subjects in the new interface
exchanged more information, in a more efficient manner, and required less oral
prompting to use the typing options.
