  abstract     = {{Location-aware services for private use such as GPS-
based navigation systems and GSM-based offerings
have become quite a success for outdoor applications,
while indoor positioning systems are still mainly
employed for professional use only. The main reasons
are cost issues and the complexity of setup and
maintenance of those systems. In this paper we
present CaMPTrack (Camera-based Multiple Person
Tracker), a prototype of a webcam-based positioning
system and discuss its application and development
challenges.}},
