A user experience framework and model within experiential living labs for Internet of Things

This paper is a follow-up of a previous paper, dedicated to the description of a holistic view of the user experience (UX) model, presenting the refined user experience framework and model within the Experiential Living Labs for Internet of Things (IoT) applications. The holistic model of UX was instantiated for six different use case domains appertaining to the Internet of Things (IoT) based services, namely: wellbeing, environment, logistics, energy efficiency, eBusiness and health. These six use cases demonstrate the difficulty to select the appropriate model elements and properties according to the IoT application context as well as to identify proper metrics for measuring UX. However, based on the six use cases experiments, a bottom-up (grounded) UX model applicable to any IoT use case appears to emerge from the empirical results. The experiments conducted within the use cases show the interest of the iterative nature of the Living Lab experiential design process for improving the design until it reaches the highest level of user satisfaction inducing an appropriate technology adoption rate by consumers. Finally, the refined Experiential Design process and UX model are presented with a set of conclusions.
