Abstract

At the core of Human-Computer Interaction are theories and methods for optimizing user experience and interactions with computing systems. In this talk, I will illustrate how HCI research could utilize machine learning and data science approaches to optimize for user experience. The motivation for this new direction is two-fold.

- First, HCI theories have largely been driving by both applied psychology approaches, including both cognitive and behavioral as well as social psychology. Existing actual practice have largely been driving by a set of practical methods including both qualitative as well as quantitative approaches, such as ethnographic methods, surveys, as well as human performance metrics of attention and cognition. As a new direction, Data Science offer much-needed new methods for understanding user engagement and behavioral traces both at the macro as well as micro personalized levels.

- Second, machine learning offer many new opportunities and techniques for optimizing toward particular user and system goals. For example, once we understand and define what are happy and engaged users (including using Data Science methods), we can use ML to optimize for creating more happy and engaged users.

In short, ML+Data+HCI is a winning formula for building user-facing systems, and in this talk, I will illustrate these ideas with a set of short stories and case studies from Google and my past research experiences.

Ed H. Chi (紀懷新) is a Senior Staff Research Scientist at Google, leading a team focused on recommender and machine learning, as well as social interaction research. Recognized as ACM Distinguished Scientist, he has led research and launched significant product features for Google Play Store and Google+. Prior to Google, he served as Area Manager and Principal Scientist at Xerox Palo Alto Research Center, where he led research on how social computing systems help groups of people to remember, think and reason. With over 35 patents and over 100 research articles, he is known for studying and modeling users' social behaviors and interactions, such as the underlying mechanisms for conflicts and contributions in Wikipedia. He is a recognized expert in intelligent user interfaces, recommenders, crowdsourcing, Web analytics, data science, and information visualization, and serves on the editorial board of ACM TOCHI and TIIS. He has been featured and quoted in the press, including the Economist, Time Magazine, LA Times, and the Associated Press. In his spare time, Ed is an avid photographer and snowboarder. Ed completed his three degrees (B.S., M.S., and Ph.D.) in 6.5 years from University of Minnesota.
