CAMAR 2.0: User-driven Context-aware Mobile Augmented Reality..,.... In this paper, we propose Context-Aware Mobile Augmented Reality (CAMAR) 2.0 platform which allows users to participate in creation and consumption of contents for a sustainable content ecosystem of community. For this purpose, the proposed CAMAR 2.0 platform augments the contents over the real world by recognizing and tracking and objects with contextual information such as location time, profile, history and social relation ship. It also allows users to author contents and mashup various types of services over the real objects with the contents in mobile augmented reality environment. Therefore, users not only can freely consume and create the contents but also selectively share them with community members. In order to validate the effectiveness of the proposed CAMAR 2.0 platform, we applied it to various mobile platforms and possible scenarios. Consequently, we expect that the proposed CAMAR 2.0 platform will play a vital role in creating and maintaining autonomous content ecosystem of community users for future computing environments.
