Overview:Visualizing and Searching Three Dimensional Archaeological Data
Site and Trench Modeling Methods:
• In situ architecture , trenches and loci modeled.
• Data can be plotted such as stratigraphy, bulk finds and special finds.
• As the user investigates the site in the Cave, trenches and loci can be turned on and off for better access or to focus on a specific area.
• The database of objects contains relative locations of bulk finds in each loci and exact locations for special finds.

• It’s difficult to see loci under or behind trenches in the Immediate field of view.
• The user may have a hard time associating objects with architecture.
• Several object types cannot be shown at once.

Interface Possibilities: Movement and Scale
Long/Coarse Movements user will access a smaller version of the world (WIM) Once the user initiates the WIM mode he/she walk around the model and interact with it freely.
Detail Exploration – Full Scale ModelThe user will navigate in this scale through a special gestural interface where small head and body movements will allow the user to have access to a specific region.
These methods are less tiring for the user and more natural. Allowing the user to change scales easily provides an appropriate vantage point to answer specific questions.

Interface Possibilities: Orientation
Visual Clutter:When interacting with a full scale model, there is a lot of abstract visual information surrounding the user and there’s a tendency to get confused.
Landmarks:Providing the user with a series of consistent – recognizable landmarks allows users a reference when they get confused.

Searches in the System:
• Current searches include 6 artifacts types and special finds.
• Users are limited 3 buttons and 1 glove command to initiate queries with.
• We would like to be able to access all the artifacts and do a large variety of queries with combinations of different finds.

Conclusion:
We have tried to solve a very general yet complicated problem, in terms of the geometry of our model, the data types involved, the amount of data and the types of analysis required.
We are trying to accommodate the needs of Archaeologistswithin the research aims and with the advice of Computer Science/Virtual Reality Interface and Cognitive Science.
Using this method we can develop novel user interfaces, advanced visual search methods in three dimensions and new methods for analyzing the 3D aspects of Archaeological data.
