"Towards Personalized Privacy Defaults"
Alfred Kobsa, Professor, Dept. of Informatics, UC Irvine

Apps and websites increasingly ask users to make privacy decisions, but people are increasingly unable to make these decisions due to limits in their available time, motivation, and their cognitive decision-making abilities. In privacy research and regu­latory practice, long-standing principles like “informed consent” and “transparency and control” are under attack. We report on work aimed at clustering users by their privacy behaviors, and to predict privacy reactions based on their cluster membership. The result could be imputed personalized privacy defaults, that call for explicit privacy decision making only in important or uncertain cases, or only by those who have a higher demand for privacy control.


Dr. Alfred Kobsa is a Professor in the Donald Bren School of Information and Computer Sciences of the University of California, Irvine. His research lies in the areas of user modeling and personalized systems, privacy, and in information visualization. He is the editor of User Modeling and User-Adapted Interaction: The Journal of Personalization Research, Associate Editor of the ACM Transaction on Intelligent Interactive Systems, editorial board member of Lecture Notes in Computer Science, World Wide Web and Universal Access in the Information Society, and was the founding president of User Modeling Inc. Dr. Kobsa edited several books and authored numerous publications in the areas of user-adaptive systems, human-computer interaction and knowledge representation. He also co-founded a national workshop series and an international conference series in these areas. He received research awards from the Humboldt Foundation, Google, and several other organizations.

"The Rhythm of Attention Focus and Mood with Online Activity in the Workplace"
Gloria Mark, Professor, Dept. of Informatics, UC Irvine

We are living in a digital age where information workers are online for much, if not most, of the day. How does this constant online activity affect people in terms of their attention focus, mood, and stress? How much do people multitask with digital media and how do interruptions affect their mood? Are people happier when doing online or offline social interactions? When are people focused and bored throughout their workday? We investigated detailed computer usage and its interrelationship with stress, mood, and focus. Using precision tracking methods of sensors, biosensors, Sensecams, and experience sampling, we studied the activity of information workers in their in situ environments. Our results show that online and offline social interactions are associated with different moods, suggesting that they serve different purposes at work. Email use is associated with negative affect and with feeling engaged and challenged throughout the day. We find that people exhibit rhythms of being focused and bored throughout the day and week, in conjunction with their particular digital media usage. I will discuss the consequences of constant online activity and how these results can inform the design of computer technologies and practices that could be used to improve people's mood, focus and stress management.


Gloria Mark is a professor in UCI's Department of Informatics. She received her Ph.D. in psychology from Columbia University. Prior to joining UCI, she was a research scientist at the GMD (German National Research Center for Information Technology), in Bonn, Germany; a visiting research scientist at the Boeing Company; and a research scientist at the Electronic Data Systems Center for Advanced Research. Mark's research focuses on the design and evaluation of collaborative systems. Her current projects include studying multi-tasking of information workers, technology use in disrupted environments and the use of virtual worlds for work collaboration. In 2006, she received a Fulbright scholarship to conduct research at the Humboldt University in Berlin. Mark has published in numerous conferences and journals, including the ACM CSCW, CHI, ECSCW, DIS, Group, and RE conferences and CSCW, CACM, and ISR journals. She was program chair for the ACM CSCW'06, ACM Group'05, and CSCW'12 conferences, and is on the editorial board of the CSCW journal.

"Game-based Learning in the Classroom"
Alf Inge Wang, Professor, Department of Information and Computer Science, Norwegian University of Science and Technology

In recent years, game-based learning has been introduced to many students across the world to increase motivation and engagement in order to increase learning. The use of video games in education and game-based learning are now most commonly used in K-12 and the results are encouraging. In this talk, I will present how game-based learning can be introduced to university or college students, as well as results from doing so. The focus on the talk will be on how classroom dynamics, motivation and engagement can be improved in lectures through game-based tool such as Kahoot!.


Alf Inge Wang is a Professor in Game Technology at the Department of Computer and Information Science at the Norwegian University of Science and Technology where he teaches courses on programming, software architecture, and game development. He received his Ph.D. in software engineering in 2001. His research interests are game-based learning, software architecture, software engineering education, and software engineering in general. He has over 85 international publications including journal papers, book chapters, and conference and workshop papers. Wang has since 2007 been the chairmain of NTNU's research program on computer games and the chairman of Norway's largest professional network of game developers and game researchers - JoinGame. Since 2012, he has also worked for his startup company Mobitroll that develops a new game-based learning platform for the classroom called Kahoot!
