A holistic model of user experience for living lab experiential design

This paper introduces a holistic approach for describing a User eXperience (UX) model that is composed of different experience types, concepts and elements. Looking at the current UX body of knowledge, several theoretical and experimental models already exist and address various aspects of the resulting user experience when interacting with a product, such as perceived usefulness, ease of use, hedonic quality and visual attractiveness to cite just of few (Forlizzi & Ford, 2000; Morville, 2004; Mahlke, 2002; Hassenzahl et al., 2000). The resulting holistic model of UX is currently undergoing empirical experiments ly in three different use case domains appertaining to the Internet of Things (IoT) based services namely, wellbeing, environment and logistics. Previous results suggest that different aspects of experience are mostly independently perceived by the users while all significantly contribute to the intention to use a product/service. The iterative nature of the Living Lab experiential design and relevance of existing elements of UX as well as value co-creation are discussed. Finally, a view of the resulting holistic model is presented with a first set of preliminary conclusions.
