Smart Spaces are an emerging technology which is gathering interest in several domains of application since they allow to supply services and to interact with users in a pervasive way. One of their basic tasks regards the localization of the users in order to provide services in a personalized and location- based way. However since the guarded area is usually complex (e.g. with occlusions) and extent several sensors must be used. In this work video data acquired by video-cameras and radio signals of the WLAN, by which user can access to services, are jointly employed to improve the association between video track and radio identifier, and, through a two step temporal filtering, it is possible to enhance the system reliability. Results are presented in a simulated environment showing the effectiveness of the proposed approach.
