Augmented Reality (AR) is the integration and co-existence of virtual images, objects and subjects within the real world.

A user of our AR system typically wears a see-through head-mounted display (HMD). A virtual character, called an avatar, is displayed on the HMD (SONY Glasstron). The user's head movements are tracked in space using an optical tracking system (NDI Polaris) to ensure that the avatar remains correctly integrated in the world when the user moves his/her head. The avatar can walk around in the real world and collision detection algorithms ensure its awareness of the furniture and other objects in it. Currently our system's real world model is restricted to a small office space.

We are capable of integrating an avatar in this space, do virtual sketching on a table, and blow virtual bubbles using a miniature microphone. Future improvements include extension to arbitrary environments, widening the currently limited field of view of the HMD, and to reduce latency.
