Amixed-initiative plannerin our context is one in which either the human or the computer can spontaneously provide the content of the same input fields. A multi-source planneris one that accesses multiple external information sources in parallel, using separate threads. This type of highly dynamic user interface is desirable but presents a challenge in "keeping the user in control" because it can be confusing to understand which fields of the form currently "belong" to the user, which ones "belong" to the system, how these two interact, and when and how their ownership changes.
