Summoning the Ghosts of Globalization: Using Invention & Immersion to Teach About Media, Image, and Culture
Thursday, 3:30 - 4:30 pm
Room 502B

At California Polytechnic State University, a team of two professors and their students have designed a device called the CompuObscura, a device that updates the idea of the camera obscura. The CompuObscura peers directly into the real but invisible world of moving images that surrounds us on the internet, on movie theater screens, and television and computer networking signals. The CompuObscura provides a pinprick view of that world, squeezed down through the focusing lens of the system's software and hardware, then projected on a wall inside the device, where viewers can interact with the ghost-like images that appear.

The presenters solicit suggestions for additions to this technology-development project and discuss how to make technology design and construction a vital part of teaching about the influence of media on culture and communication.
