the Zone. Views through a context-aware mobile portal

Context-awareness can make mobile services more easily available and spontaneous to use. By identifying the user’s context, the service can offer information related to that context. It can also make the user more aware of the social surroundings. The paper describes the system and conceptual approach that are used to study context-awareness in the project Kontti (Context-aware service for mobile users.) The developed prototype can act as a very personal guide that provides context-aware services and up-to-date information about the contexts of friends. The system and the concept were evaluated in everyday use in spring 2003. The evaluation yielded a group of service concepts, which will be studied further
