Despite the technological advances in the areas of mobile computing and cloud storage, these planning processes are still tedious. In this paper, we propose a user-centred planning process for scheduling appointments between users. We describe the algorithm derived from the process, and present a first prototype for a mobile calendar application that implements the proposed process.enText/Conference Paper1617-5468
