In the current IoT era, the number of smart things to interact with is raising everyday. However, each one of them precises a manual and specific configuration. In a more people-friendly scenario, smart things should adapt automatically to the preferences of their users. In this field, we have participated in the design of People as a Service, a mobile computing reference architecture which endows the smartphone with the capability of inferring and sharing a virtual profile of its owner. Currently, we are developing Digital Avatars, a framework for programming interac-tions between smartphones and other devices. This way, the smartphone becomes a personalized and seamless interface between people and their IoT environment, configuring the smart things with information from the virtual profile. In this work, we present a formalization of Digital Avatars by means of a Linda-based system with multiple shared tuple spaces.
