Collaboration environments provide the necessary tools to conduct a meeting and perform tasks together through devices and interaction techniques. Currently, investigations about Proxemics and F-Formation patterns show how these concepts can be used to improve the interaction between people and devices, considering the distance between them. However, there is not a broad perspective respect to use them with Cross Device. In this paper, a taxonomy of interaction techniques based on F-Formation patterns is proposed in order to be used as a guide of good practices for the development of future Cross Device Applications.
