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.


  • [Dec 2017] IEEE CG'17 Best Paper: John O’Donovan and collaborators at ARL and RPI receieved best paper award for their work on misinformation propogation with uncertainty in social media. Announcement available here).
  • [Feb 2017] CHI17: Research by former lab member Saiph Savage (& team at WVU), in collaboration with Tobias Hollerer, John O’Donovan and Angel Ortega (undergraduate researcher) on combatting bias in news media was accepted to ACM CHI’17 (late breaking track).
  • [Feb 2017] Keynote talk: John O’Donovan will give a keynote talk at the “AWARE” workshop on awareness interfaces and interactions, to be held at IUI 2017 in March.
  • [Jan 2017] ACM IUI Award: John O’Donovan to receive inaugural award for most-influential-paper of ACM IUI conference series, for his 2005 paper on “Trust in Recommender Systems” (link to article) (link to ACM award notice). John will present an invited talk about the work at IUI’17 in Cyprus.
  • [Dec 2016] Ph.D. Defense: James Schaffer successfully defended his Ph.D. dissertation entitled “A Quantitative Investigation into the Design Tradeoffs in Decision Support Systems”. Congratulations, James!
