Active Surroundings - A Middleware for People-Centric Pervasive Computing
Information and Communications University, Taejon, Korea

Active Surroundings is a middleware that helps build various applications for pervasive computing environments. Like other systems, it enables applications to be dynamically adapted to the current context of a user without asking the user's involvement as he or she moves from one place to another. However, most of the existing approaches are focused on individuals rather than a group of people.

In the real world, people interact with each other and live in various types of groups such as family, company, and interest groups. Active Surroundings aims to support a group-centered pervasive computing environment. Within a group, context conflicts commonly occur because every person not only has different preferences but also makes different decisions or interprets differently with same context. The system should harmonize the preferences of members and currently available resources in an environment.

To support a group-centered pervasive environment, Active Surroundings consists of four components such as environment sensing, context management, dynamic reconfiguration support, and adaptive service discovery. We have built its prototype and are currently working on detailed design of each component.
