Device Collaboration System Based on Context-Aware Architecture in Smart Environment

In recent times, research is being actively carried out to enable the seamless use of a single content using many different varieties of devices in smart environments, anytime, anywhere. However, present researches are limited to receiving provider-centered services from various cell phones with the same operating system and therefore this thesis suggests, within this model, a device collaboration system based on context-aware architecture to provide a user-centered service. To allow content sharing between different devices, this system collects not only internal/external contextual information but the locations of all devices within the smart environment, resources and service information. Then, through suggested context interpretation structure it predicts the user's intention and service, and selects the best device right for using the content to be run and therefore provides a personalized user-centered service. To verify the suggested system structure, smart environment and scenario were built and whether or not the content sharing service functioned through the best device depending on context-awareness was tested.
