RENCI at UNC-Charlotte has a Multi-Touch Table in the Visualization Center!

I wish this multi-touch table was around when I last took a class at UNC-C! With help from the RENCI Europa team, this table that was only a dream was finally built.

The following information was posted on the RENCI Vis Group Multi-Touch Blog
:

"Jason Coposky and Warren Ginn from RENCI Europa delivered UNC-Charlotte’s Multi-touch Table to the
Charlotte Visualization Center last week. Dubbed the Urbanization Explorer Touch Table, the device’s first role will be to display the Urban Growth Model, developed by the Center for Applied Geographic Information Science (CAGIS) and UNC-Charlotte’s Urban Institute. By accessing historical patterns of growth in the region, this application will provide forecasts on how much growth is expected to take place based on these historical patterns. Using satellite imagery for the 24-county region around Mecklenburg, for four time periods: 1976, 1985, 1996 and 2006, the Urban Growth Model tracks the advance of impervious surfaces, a key indicator of development, in expansion across the area since 1976, and estimates the extent of urbanization through 2030. With interfaces developed by collaborators at the Charlotte Visualization Center, multiple users will be able to select areas of interest, zoom, pan, and navigate the colorful, large-format maps using only their fingertips and on-screen digital tools."

"First introduced at North Carolina State University’s Institute for Emerging Issues annual forum this past Februrary, this multi-touch table represents the next leap in performance in touch tracking. As opposed to the previous Direct Illumination (DI) technique employed in the original table, this table employs Diffused Surface Illumination (DSI). By employing a sheet of Cyro Acrylite EndLighten with polished edges and LED Edge-View Ribbon Flex from Environmental Lights, we’ve been able to distribute the IR illumination more evenly."

"Infrared LEDs on a trip from Environmental Lights is applied to the inside perimeter of the frame where the polished Endlighten acrylic sheet will be installed."

I want one to try out my touch-screen experiments!
