Technological advances increase the possibilities for the aesthetics of interaction and the user experience. This is a growing field in the Human-Computer Interaction community (HCI). However, Lenz et al.  show that little is known about the relation between experiences and interaction. The current study explores this relation through the design of an interactive lamp. We compare a direct and a delayed coupling between the user’s action and the reaction of the light. The results provide empirical evidence that deliberately violating one of the unification principles (i.e., delayed response) triggers a more positively engaged experience. We discuss the result and further implications for design research.
