WP9: The area
Usability traditionally focuses on goals such as effectiveness, efficiency, safety, utility, learnability, and memorability
Affective interaction focus on user experience goals – subjective qualities such as being fun, rewarding, motivating, satisfying, enjoyable, and helpful
How do we design for user experiences – and make sure that it works?

In Situ Informants: results
Support the fragile communication rhythm that friendships require – memories of the past, sharing the present and planning for the futureEmotions are not singular state that exist within one person alone, but permeates the total situation, changing and drifting as a process between the two friends communicating Gained insights into the physical, sensual aspects of emotional communication and caused reflectionsIn situ informants method required involving study participants in the interpretation of the data and establishing a close connection with spectators

Results
Users moved across a conceptual space anchored in real life on one end and in fantasy on the otherFantasy was used most of the time to reflect real life occurrences

Think aloud as evaluation methods
Do users who “think aloud” give off expressive data that can be recognised by others?
First impressions: positive! But sometimes users show positive expressions while experiencing negative events (e.g. irony)
Aim: to produce a checklist of methodological issues that practitioners can consult to make better experience assessments

Mihaly Csikszentmihalyi: Flow
To remember the past is not only meaningful in order to create and maintain your personal identity, but it can also in itself be a very pleasurable activity. [..] To keep the past registered can contribute to quality of life. It frees us from being enslaved by the present and makes it possible for our minds to visit the past. It makes it possible to choose and in our memory keep events that have been particularly pleasant and meaningful and thereby “create” a past that helps us to deal with the future.

Example: Affective DiaryMeaning-making, reflection and change
”[pointing at the first slightly red character] And then I become like this, here I am kind of, I am kind of both happy and sad in some way and something like that. I like him and then it is so sad that we see each other so little. And then I cannot really show it.”

Issues
Clash between different views:User-centred, design-oriented perspective Scientific, evaluation-oriented, theoretically-driven perspective
Also different views on emotion in interaction:Interact, integrate with overall system purpose, emotion as a co-constructed, co-interpreted phenomenon – interactional viewInfer, diagnose, communicate, react – informational view
