A pervasive watch-over system based on device, user and social awareness

In this paper we propose a gentle system for watching over for pervasive care-support services that fulfill users' actual requirements and without interfering the users' privacy. In this system, we cope with not only the user's physical location but also all the situations of pervasive devices and requirements of associated users, in "both" sides of watching and watched sites. Moreover, social relationships between observers and a watched person are used to give an adequate privacy level to the services. To do this, we propose a pervasive watching over system "uEyes". In uEyes we introduce three distinguished features for the watching, they are (S1) Device awareness, (S2) User awareness and (S3) Social awareness. To realize these features, an autonomous decision making ability and cooperative behavior are employed to each element in the system. Based on these advanced features, a live video streaming system is autonomously constructed according to the device status and the user's situation, on both sides in runtime. As a result, the gentle watching-over service can be effectively provided.
