CAPNET Challenger & Experiments


1/2005 - 2/2007


The purpose of CAPNET (Context-aware Pervasive Networking) research program is to create a foundation for new information and communications technologies and for business in the field. The focus is on context-aware mobile technologies for ubiquitous computing. This kind of information and communications technology and mobile services together form one of the most promising business fields in the near future.

The first three-year period of the CAPNET program included two projects, Spearhead and CAPNET Technology Enablers (CTE). The first one was one of the four spearhead projects of the NETS Technology Program of the National Technology Agency of Finland. During the Spearhead and CTE projects several prototype demonstrations were created, the distributed component architecture was developed, and several scientific publications and theses were made.

The researchers will keep on doing the work done in the first CAPNET program, and in addition to that work they will concentrate also on new research themes. The Challenger project emphasizing basic research focuses on the familiar themes like utilization of context, service discovery mechanisms and user experience. Context (e.g. time and place) information determines and steers the functionality of applications used, and expressly that information and utilizing it have been the most essential ideas of the CAPNET program. The attention will be drawn also to methodological issues and the development of the basic technology.

The Experiments project is an applied research project in the strict sense of the word: researchers will focus especially on the prototypes utilizing interesting and challenging technologies and platforms. This kind of technologies include besides existing, widely used techniques also RFID technology with sensors, for example.

Also dynamic application development, new applications, application scenarios, and routine learning are important issues, and the usability of so-called physical user interfaces will be regarded. General ontology will be designed for the component architecture.

The researchers taking part in the projects work in the different research groups of the University of Oulu: MediaTeam, Intelligent Systems group (Computer Engineering Laboratory) and INTERACT (Department of Information Processing Science). Also three foreign research institutes participate in the research: Waseda University (Japan), Institute for Advanced Computer Studies, University of Maryland (USA), and University of Linköping (Sweden). Industry partners are Capricode, IBM, Nokia, Serv-It and TeliaSonera.
