Lessons From Being There: Interface Design for Mobile Augmented Reality

Virtual 3D worlds used to be accessible primarily through display systems separating the users from the physical world and immersing them in a parallel computer-generated virtual reality. Today, virtual 3D worlds are being merged into physical space, creating not only virtual but also augmented realities (AR). In contrast with virtual reality, augmented reality facilitates mobility in the real world as well as a close relationship between physical space and virtual objects. This makes AR an interesting approach for human-computer interfaces in mobile use contexts.
