14 humaine wp9: Users & Usability 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

16 humaine wp9: Users & Usability 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.
