Plenary meeting, 4th of June, Paris

wp9 the area
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
In Situ Informants: results
  • Support the fragile communication rhythm that friendships require – memories of the past, sharing the present and planning for the future
  • Emotions 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 reflections
  • In situ informants method required involving study participants in the interpretation of the data and establishing a close connection with spectators

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

think aloud as evaluation methods
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.

”[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
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 view
    • Infer, diagnose, communicate, react – informational view
