Dissertation/Thesis Abstract

Describing and analyzing interactive experience over time
by Huang, Chung-Ching, Ph.D., Indiana University, 2015, 230; 3716196
Abstract (Summary)

User experience changes over time as a consequence of prolonged engagement with many products or services. Interaction evolves as we learn, adopt, and shift from old use patterns to new ones. Scholarly work in HCI has been successful in its investigation of interactive experiences situated in current places and times. This dissertation aims to provide a complementary perspective by paying attention to user experiences that happen in the past. In particular, it explores visual thinking as a method of describing and analyzing interactive experiences over time.

In addition, this dissertation has a pragmatic purpose: to develop applicable research approaches for professional practice. My professional experience as a designer yielded the insight that many practitioners collect user stories as references for envisioning possible futures. However, the collection and application of user stories can be improved. In many cases, the analysis of user stories is fragmented and lacking a systematic approach. Scholars are in a unique position to support practitioners by developing cohesive, systematic methods. I believe that academically developed methods should aim to support professional practice.

The overall aim of this dissertation is to produce methods for studying users and artifacts, the two essential components of a user experience.

The research commenced with a preliminary study of the use of visual diagrams as interview aids for recalling daily email usage. The research continued with a review study comparing different existing approaches to using visual support in user research as well as an analytic study of how to examine the history of interaction artifacts using "visual annotations." Finally, the research concluded with an exploratory study wherein timeline annotations of "retrospective interaction histories," were applied in workshops. Following these four studies, I examined how visual methods in a retrospective study might help capture and represent heterogeneous individual user experiences. This examination led to my proposal of a theory of temporal anchors. Temporal anchors capture the idea that the measurement of user experience over time and the history of interactive artifacts might serve as anchor points in users' retrospection. I conclude the dissertation with a discussion of potential future research directions.
