Internet of Things (IoT) is a new paradigm that includes a network of smart objects, which are embedded sensors, communicating using the Internet. One of the areas that are leading up to IoT is Ubiq- uitous Computing (UbiComp). There are thus solutions such as frame- works, middlewares, and other development artifacts that come from the UbiComp community and can be used for IoT applications. On the other hand, the interaction evaluation of the applications can be more complex in IoT than in UbiComp systems, once we have two different perspec- tives: Human-Thing and Thing-Thing interactions. In this paper, based on the literature, our experience in these two domains, and case studies with Ubicomp and IoT applications, we discuss how we can benefit from the UbiComp move towards IoT, focusing on the main differences and similarities related to interaction evaluation. These differences open a set of questions that are also presented and discussed in this paper.

The evolution happened due to the association with other areas, such as Cloud Computing, and the hardware advance, which allowed the improvement of the sensors, actuators and the creation of smaller devices with a network connection [1]. In this paradigm, we have several things communicating between themselves. R.M.C.
