7/30/11 Creative Science Augmented Reality (AR) � � Inclusion of virtual objects in the real world � � Our interest is to reconstruct 3D models of ancient buildings in situ. � � This makes visits to cultural heritage sites more interesting and preserves the original structures. 2

7/30/11 Research Issues (1/2) � � To generate the right view of a 3D model, we have to know where the person is standing and which direction they are looking. � � Conventionally, these have been done using GPS and orientation sensors - but GPS in particular is too inaccurate for a mobile user. � � To overcome this, we are exploring SLAM, a technique from robotics for working out where you are relative to your surroundings as you explore them. Research Issues (2/2) � � An environment with only static 3D models quickly becomes boring. � � To introduce dynamic content, we can use “AI agents” (chatterbots, etc.) to interact with the user. � � We are particularly interested in agents that adapt to the user and teach him or her something about the environment in which they are immersed. 3

7/30/11 Science Fiction Prototype Stories and Reflections (1/4) � � Medieval Ages: � � Marker-based tracking (Figure courtesy ARTag) 4

7/30/11 Stories and Reflections (2/4) � � Real image from The Tower of London (below, left) � � Reflection in the game M&B (below, right) Stories and Reflections (3/4) � � Ancient Ephesus: 5

7/30/11 Stories and Reflections (4/4) Conclusion � � We want to move from static augmentation to a more interactive, immersive experience. � � There are many applications beyond cultural heritage: civil engineering, surgery training… 6
