Center node: "Smart spaces: a metacognitive approach"
  Abstract: Smart spaces provide services that support users in their daily lives. This requires the smart spaces to recognize the situations and adapt to them. Identifying the situation and adjustment to it in the physical environment has attracted lots of research, but recognition and adaptation at the meta-level has not been studied much. We refer with meta-level recognition and adaptation, that is, with metacognitive functionality, to evaluating the decisions made by the smart space and to adapting the decision making to maximize user experience. The main objective of this PhD work is to equip smart spaces with metacognitive functionality and the expected main contribution is a general framework for Metacognitive Smart Spaces (MSS).
