Designing for Human Emotion
Emotional reactions are a key part of the user experience with technology, and a growing concern as emotion is recognized as central to human decision-making and behaviour. My dissertation aims to deepen our understanding of how emotions change as an interaction experience unfolds, how to assess such emotions, and what patterns exist.
I feel that this work is important because it brings attention to emotion in the human factors field, and attendees include practitioners who may be able to incorporate emotion aspects in their technology evaluation practice.

In summary, this thesis contributes a collection of validated, usable self-report tools, empirical findings relating emotion to videos, two novel psychometric properties to characterize complex and rich rating data, individual and cultures differences, learning rates and finally, relationships and tradeoffs of emotional self-report concerning evaluation of practical real-world systems.
This article initiates a dialogue between disciplines in the emerging field of interaction design and emotion measurement, a dialogue which is critical to advance the state of the field. We aimed to raise the current discussion from critiques of methods (e.g., quantitative versus qualitative, physiological versus self-report) to lay out a framework to appreciate epistemological differences in design approaches. We value appreciation for epistemic differences between researchers, and propose a path to facilitate collaboration: disciplined interdisciplinarity.
