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.

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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
