Introduction - If you have any usage issues, please Google them yourself
One factor that has limited the use of Bluetooth as a networking technology for publicly
accessible mobile services is the way in which it handles Device Discovery. Establishing
a Bluetooth connection between two devices that have not seen each other before is slow
and, from a usability perspective, often awkward. In this paper we present the
implementation
of an end-to-end Bluetooth-based mobile service framework designed specifically to
address this issue. Rather than using the standard Bluetooth Device Discovery model to
detect nearby mobile services, our system relies on machine-readable visual tags for outof-
band device and service selection. Our work is motivated by the recent proliferation of
cameraphones and PDAs with built-in cameras. We have implemented the described framework
completely for Nokia Series 60 cameraphones and demonstrated that our tag-based
connection-establishment technique (i) offers order of magnitude time improvements over
the standard Bluet
