Hybrid interactions in pervasive computing settings

There are so many interactions in pervasive computing environments that should be done automatically. Sometimes even users don't know about some interactions that are done in his/her devices. It refers to a concept based on a vision described by Mark Weiser. “The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it”. In this paper, interactions in pervasive computing environment and some classifications of interactions are discussed. Hybrid interaction initiated by users and hybrid interaction initiated by smart object are two sub set of interactions in the classifications that are explained in this paper by two concrete examples: an event interaction system, and a Location information sending system. These interaction patterns are analyzed in such a pervasive computing setting where information about user's context is derived by combination of active and passive tags present in user's environment. In this route, pervasive RFID technology and Bluetooth-enabled active tags that are augmented to everyday objects are used.
