MyPlace Locator: Flexible Sharing of Location Information

摘要

As location information plays such an important role in pervasive and context-aware computing, location modelling can be cast as a particularly important user modelling problem. Moreover, given the potential sensitivity of personal information about location, it is critical to ensure adequate user control over the use of the location user modelling information. This paper describes MyPlace Locator, a system for modelling people's location, based upon a range of pervasive sensors. A critical feature, the focus of this paper, is the user model control: users can determine the granularity in space and time of the location information released from their model. Users can do this on the level of a single user or a group of users. We describe the interface and report its qualitative evaluation.
