Who we are

Welcome to the UCSB Four Eyes Lab, in the Department of Computer Science and the Media Arts and Technology Program at the University of California, Santa Barbara. Our research focus is on the "four I's" of Imaging , Interaction, and Innovative Interfaces. The lab is directed by Professors Matthew Turk and Tobias Höllerer, and Dr. John O'Donovan. It includes several graduate and undergraduate students, postdocs and visitors.
