Abstract:
Networking and embedded technology made it possible to integrate physical objects with information infrastructure and augment the physical environment with information and computing functions. As a result the physical space becomes a Physical-Information Dual Space. The user can interact with cyberspace in the 3D physical space in stead of just in front of computers. In the Dual space the interaction can be carried out in three layers: interface, service, and system in more intuitive and natural way for users. To establish Dual relations in the interface layer makes the object surface, paper document even the contents becoming the interface; Dual relations in the service layer allow the content based information index and retrieval. In the smart space the Dual relations in the system layer will be able to carry out implicit interaction with users.
Key words: HCI, information space, dual space, interface, implicit interaction
