Navigation-tools currently give us directions from location A to B. They help us with the physical process of moving from here to there. Tasks in general, are achieved by the subsequent determination and execution of sub-tasks until the goal is achieved. To help achieve the higher-ranking task, we commonly use so called "personal information management"-tools (PIM-tools). They offer possibilities to manage and organize information about errands that have personal or social implications. Such tasks are described in informal ways, todo-lists for example offer the storage of textual description of an errand, sometimes allowing geographic or temporal information to be added. The paper proposes a formalism that can produce instructions leading from A to the fulfilment of the "task". Thus connecting the high-level task, that represents intentions, with the physical level of navigation.

PIM - task planning - routing - LBS - shortest path
