In this paper, face recognition systems that have been developed for smart interactions at the interACT Research Center is presented. The face recognition efforts at the interACT Research Center consist of development of a fast and robust face recognition algorithm and fully automatic face recognition systems that can be deployed for real-life smart interaction applications. The face recognition algorithm is based on appearances of local facial regions that are represented with discrete cosine transform coefficients. Many fully automatic face recognition systems have been developed based on this algorithm. Among these systems two of the portable ones will be shown as interactive demos. Moreover, demo videos will be shown for the other systems.
