Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- This paper describes a system where Internet-enabled sensor technology was integrated into a context information platform to give viewers of sport events an enriched media experience. The system was developed as a proof of concept and was evaluated during real-life use at the Vasaloppet cross-country ski event. Using Bluetooth wireless ad-hoc networking and GPRS technology, sensor data was transmitted from contestants to a context information platform, which in turn presented the sport event viewer with a personalized, context-aware view.

- This paper describes a system where Internet-enabled sensor technology was integrated into a context-aware platform to give viewers of sport events an enriched media experience. The system was developed as a proof of concept and was evaluated during real-life use at the Vasaloppet cross-country ski event. Using Bluetooth wireless ad-hoc networking and GPRS technology, sensor data was transmitted from contestants to the context-aware platform Alipes, which in turn presented the sport event viewer with a personalized, context-aware view. In this paper we discuss the system architecture and integration of components. The system was evaluated both from technical and user perspectives, where the evaluation results confirm our approach to be technically feasible and that the system provide an enriched media-experience for the majority of viewers.

- This paper presents an evaluation of Bluetooth positioning in a general positioning platform. Proceeding the evaluation a Bluetooth based positioning system was implemented in order to complement the theoretical evaluation with empirical tests. Three different ways of positioning with Bluetooth have been developed. With a registered positioning service a Bluetooth device has an active role in the positioning task as it sends a position on request. A Bluetooth device can also take a more passive role in a positioning task, where the unique address of the device is used by a connected device to look up respective position in a database. It is also possible to forward a position gained from the positioning platform using the peer to peer characteristics in Bluetooth. This paper does also contain a discussion on the theoretical time requirements for a positioning system based on Bluetooth. Empirical tests show that these requirements hold.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Research on positioning systems and context-aware applications are being performed in the Alipes project at CDT, Luleå University of Technology, Sweden. An evaluation of Bluetooth as a possible technology for positioning was performed during autumn of 2001 in this project. Proceeding the evaluation a Bluetooth based positioning system was implemented in order to complement the theoretical evaluation with empirical tests. Three different ways of positioning with Bluetooth have been developed for the Alipes project. With a registered positioning service a Bluetooth device has an active role in the positioning task as it sends a position on request. A Bluetooth device can also take a more passive role in a positioning task, which is when the unique address of the device is used by a connected device to look up a position in a database. It is also possible to forward a position gained from a positioning platform like Alipes over Bluetooth. This paper presents a Bluetooth positioning system where the three ways of positioning are implemented. The evaluation and conclusions of Bluetooth as a positioning source and how well Bluetooth performs in such a task are being discussed. To give support to the statements the implementation and tests are also presented.
