Kansei physiological measurements and contructivist psychological explorations for approaching user subjective experience during and after product usage

⌈Résumé⌋ The aim of this article is to explore the suitability of psycho-physiological measures (e.g. levels of pleasure, excitement and comfortableness during the usage obtained from physiological measures) and psychological explorations (e.g. users’ reflections about their needs for interaction obtained from an interview) for approaching user subjective experience during and after the interaction with a product takes place (explorative usage and reflection processes).
For this purpose the 2-point Electroencephalogram (EEG) comfort measurement is used to gather realtime information about how a person feels during the interaction with a product and the Repertory Grid Technique (RGT) interview is used to gather information about what people’s primary goals and concerns are and about the meaning placed on the purpose outside the immediate experience (after interacting with a product).
