Abstract

Traditionally, location systems have been built bottom-up beginning with low-level sensors and adding layers up to high-level context. Consequently, they have focused on a single location-detection technology. With sharing of user location in mind, we created Personal Location Agent for Communicating Entities (PLACE), an infrastructure that incorporates multiple location technologies for the purpose of establishing user location with better coverage, at varying granularities, and with better accuracy. PLACE supports sensor fusion and access control using a common versatile language to describe user locations in a common universe. Its design provides an alternative approach towards location systems and insight into the general problem of sharing user location information.
