Novel Interactive Mode Based on Face-Recognition and Facial Orientation-Estimation Applied to AmI

A novel ambient intelligence interactive technique are introduced here. First, the mechanism of our AmI system and several idiographic technique issue is expounded stepwise. For providing personalized service an algorithm of face recognition based on HMM is researched and the experimental results show efficient. In this way the user can be identified by the method of face recognition, and the system with a LCS can provide personalized services. Otherwise, we adopt the wavelet analysis and template matching technique to estimate the user´s basic face orientation, thus the video projector is driven to rotate toward the same direction. In sum, the study described here is likely to be used in intelligent meeting or medical treatment environment.
