U-Interactive: A Middleware for Ubiquitous Fashionable Computer to Interact with the Ubiquitous Environment by Gestures

In this paper we present a system, called U-interactive, that provides spontaneous interactions between human and surrounding objects in heterogenous ubiquitous computing environments. Our U-interactive system introduces a virtual map, which contains interactive objects around a user in each ubiquitous environment. In the virtual map, each interactive object is tagged with geographic information and attributes to interact with. Each user can create interactive objects in the virtual map corresponding to physical objects. Also the scope of the map is automatically adjusted according to user’s location (inside building or outdoors) by location services. U-interactive system runs on both mobile devices and infrastructures. U-interactive system provides interoperability with communication methods, such as UbiSpace, UPnP, and Web services. We developed our U-interactive system upon a prototype of ubiquitous environment. U-interactive system contains interactive kiosk, printer, sensor networks, and users.
