An Overview on Collaborative Augmented Reality Environment Potentials in Urban Planning

This paper describes an augmented reality (AR) environment that allows multiple participants or multi-user to interact with 2D and 3D data. AR simply can provide a collaborative interactive AR environment for urban planning, where users can interact naturally and intuitively. In addition, the collaborative AR makes participants in urban planning to share simultaneously a real world and virtual world. The fusion between real and virtual world, existed in AR environment, achieves higher interactivity as a key features of collaborative AR. In real-time, precise registration between both worlds and multi-user are crucial for the collaborations. Common problems in AR environment will be discussed and major issues in collaborative AR will be explained details in this survey. The features of collaboration in AR environment are will be identified and the requirements of collaborative AR will be defined. This paper will give an overview on collaborative AR approach potentials in urban studies and planning. The work will also cover numerous systems of collaborative AR environments for
