1. What can CS do for Archaeology? (and vice versa) John Hughes Brown University Providence (visiting EVASION/INRIA 2003-2004) All images courtesy of Eileen Vote, Brown University and the ARCHAVE project

2. Field collection support Post-collection analysis Post-collection dissemination of site-experience Fragment assembly Some General Problems Objects from the Petra Great Temple Excavations

3. 3D shape representation for recording and documentation (images and video) Reconstruction of 3D objects for artifact reconstruction (pottery) Analysis of the 3D aspects of the record (databases and visualization) General Problems

4. ARCHAVE Features Context Visualization Tools

5. Potential applications: CS  Archaeology Biased towards graphics GIS applications may suggest new ideas

6. Shape/appearance matching: “Find me all the other artifacts that look a bit like this one” …or “like a piece of this one” 3D database search is rapidly getting close to supporting this

7. Presentation Tools “Help me display my data in a compelling way to others” –“Let me highlight the important features” –Give rough sketches where only rough information is known –“Make it easy to put on a web page, a video, or slides” “Expressive Rendering” literature Adaptive layouts McCloud “Understanding Comics” Help me share the experience of being an archaeologist.

8. Interface design “I need a way to do my scientific work in this CAVE, but I can’t bring my laptop with me!” Convenient tools for day-to-day research in context of VE …wide open research area…

9. “Graphical Models” Is it possible to estimate the distribution of shapes in some site to make reasonable guesses of missing shapes from the ones we see? Treat collected data as samples from unknown distributions with (partly) known relations.

10. Potential applications: Archaeology  CS Testbed for expressive rendering in virtual environments “What are the tensions between ‘expressive rendering’ and a sense of reality?” What happens when you put “marks” – brushstrokes, pen-lines, etc. – in 3D?

11. “The Agora is a space first, and not just a building”: data representations CS builds “general” models… –… but when we encounter real data, our models are inadequate We don’t handle… –qualitative data –missing data –higher-level characteristics (“what is the space?” instead of “what are the shapes?”)
