Interacting with the User in Calendar Management

The management of personal and shared schedules is limited by the lack of flexibility of time management services. Online calendar managers fail to support reasoning about time and multi-user activities. Task schedulers fully control the temporal allocation of events without involving their users in decision making. As an attempt to address such issues, this paper presents a mixed-initiative scheduling model supporting interactive calendar management. Our model is applied in MARA (Mixed-initiAtive calendaR mAnager), which enables users to solve scheduling problems by incrementally exploring the solution space.
