Conference: College Art Association (CAA) Location: Los Angeles Convention Center, CA Dates: February LITHICS VISUALIZATION PROJECT Session Title: Lithics Visualization for Analysis of Patterns and Aesthetic Presentation Co-author/speaker: Georgia Gene Berryhill, Ph.D. - University of Maryland - UMUC Co-authors: Thomas E. Levy, Ph.D. - University of California, San Diego Lev Manovich, Ph.D. - University of California, San Diego

Session: Information Visualization as a Research Method in Art History Session Chairs: Christian Huemer, Getty Research Institute Lev Manovich, University of California, San Diego Main Points: Scholars are interested in Information Visualization for their research. Large-scale digital collections provide online access to materials. Information Visualization enables exploration of complex relationships and patterns of visual artifacts. FIG. 1

FIG. 2 Type of Lithic: Pressure flaked Neolithic Arrowheads (ventral and dorsal views)

LIGHTROOM - To date, close to 1000 arrowheads in the catalogs. FIG. 3

Initial Objectives: Photograph a visual collection/database of the lithics which will provide a large sampling suitable for visual analytics. Explore aesthetic presentation potentials. Utilize new software and computer interfaces. FIG. 4

ImagePlot FIG. 27 Once the measurement of each arrow in every photo is complete, we use ImagePlot software developed by Software Studies to create high resolution visualizations where the arrows are positioned according to various combinations of these measurements, as well as the categories normally used by archeologists to describe these artifacts.
