A human centric approach to the Internet of things

This research focuses on human interaction with the IoT, not only from the perspective of the user, but also considering the requirements that smart objects should meet to support human activities. It analyses how the IoT was originally conceived from a technology and data driven approach, and why there is a need to provide an IoT framework that considers humans’ tasks and goals. As such, the nature of the actions and interactions found in a human-based IoT are discussed in the context of social-like collaborations, where actors are in pursue of a common goal. This thesis reframes Human-IoT interaction as a social, collaborative system, described in terms of its capacity to support the activities of the involved social actors in pursuit of a common goal. A structure is proposed to describe the nature of these interactions, and a methodology to model user behaviour based on the tasks and goals supporting a theme is proposed. The methodology is used to analyse the requirements of a domestic IoT system, leading to the implementation of a demonstrator system, and a study to validate the method. This research posits that user experience should inform IoT system design to prevent misunderstanding of its purpose
