VIDEO PROCESSING AND UNDERSTANDING TOOLS FOR AUGMENTED MULTISENSOR PERCEPTION AND MOBILE USER INTERACTION IN SMART SPACES.

In this paper, a complete Smart Space architecture and related system prototype are presented. The system is able to analyze situations of interest in a given environment and to produce related contextual information. Experimental results show that video information plays a major role for what concerns both situation perception and personalized contex-aware communications. For this reason, the poropsed multisensor system automatically extracts information from multiple cameras as well as diverse sensors describing environment status. This information is then used to trigger personalized and context-aware video messages adaptively sent to users. A rule-based module is encharged to customize video messages in relation to the user profile, contextual situation and users's terminal. The systems outputs graphically generated video messages consisting of an animated avatar (i.e. Virtual Character) closing the loop on users. Proposed results validate the conceptual schema behind the architecture and the successful adaption to the analysis of different situations. [ABSTRACT FROM AUTHOR]
