Massively Multiplayer Online Worlds (MMO) are persistent virtual environments where people play, experiment and socially interact.

In this research project, we demonstrate that MMOs also provide a powerful platform for Augmented Reality (AR) applications. We introduce the notion of  AR Stages, persistent, evolving spaces which encapsulate AR experiences in online three dimensional virtual worlds.

Based on the 3D virtual world Second Life, our custom client software blends together locations in physical space with corresponding places in the Second Life virtual space and leverages the power of the MMO to create an powerful AR authoring environment targeted at a wide audience and fields of application.

We examine the technology and workflows necessary to integrate AR in MMOs and create novel Augmented Reality Experiences.
