Profile

Dr. Christou received his Ph.D. in Computer Science from Tufts University in 2007. He has been employed at European University Cyprus since 2007, and prior to that he was employed at Cyprus College since 2003. His research interests revolve around Game Design, Development, and Evaluation. He has published several articles in journals and conferences, and has taken part in various funded research projects, both national and international. He examines video games so that he can create useful game design guidelines that encapsulate game designer experiences in a concise way, so that they can be reused for the development of successful games. To this end, he is looking at other research avenues, such as the societal effects of interactive technology, and online society examination, with a focus on online gaming societies, such as World of Warcraft, Age of Conan, etc. Dr. Christou also examines player perceptions and how these change over time. Through in-game ethnographic studies, and studies of player behavior, he examines how players view the games they play while they play them, and as they develop a relationship with them.


Previously his research has revolved around the evaluation of Usability and User eXperience. Towards this end, he worked extensively on the evaluation of Reality-Based Interaction (RBI). He believes that we need to have evaluation mechanisms in place, both quantitative and qualitative, that provide various measures of usability and user experience, as they now exist (at least for usability) for WIMP interfaces. These evaluation mechanisms must allow comparisons between the different constituent interaction styles that belong to the RBI umbrella, so that different solutions may be compared. Thus, his research aimed to provide such evaluation mechanisms that are interaction style-blind, so that evaluation results from different interfaces designed in different interaction styles may be compared. This chapter of his research has summarized in his Ph.D. dissertation and various journal and conference papers he has authored. In early 2011 he co-edited a special section of the International Journal of Human-Computer Studies on the challenges of the design and evaluation of RBIs.
