Various thoughts about the concept of space have brought a variety of paradigms to the trend. Just as existing information innovation applied activity and function of physical space for computers to overcome time and space limits, future space transplants intelligence to all the objects as organic whole in electronic and physical space by using IT technology to create emotional space. The most universal housing space in our living has had considerable changes in application of life style and technology. However, advanced technology space which corresponds to acceptance and desires of residents does not meet the needs and emotion of residents because of its limited network system. Therefore, it should be transformed into smart space which stimulates human emotion in the trend of advanced technology culture. As future residential space needs technological elements and design process which can stimulate human emotion, this study is to analyse it as a base of emotional design. This study aims to present characteristics of space image for space realization which meets the age of smart technology in terms of unifying smart space with emotional design, focusing on four future housing galleries shown by construction companies. First, the study speculated smart space in theory and classified characteristics and types of smart space into connectivity, sensitivity, reiteration and variability according to changes in space paradigm. Second, the study identified the background and main points emotional design appeared, analysed types of smart space based on characteristics of experimentation, connectivity and symbolism and speculated characteristics of emotional design in each type. In respect to characteristics of emotional design in smart space, organic connection and sensitivity are remarkably presented through experimentation and reiteration is presented through organic connection and experimentation, and variability through symbolism and experimentation.
