Taxonomy of ubiquitous computing service for city development

Due to advanced information and communication technologies, the paradigm of cities has been changing. This new paradigm is pursued in different concepts and methods depending upon countries; however, common characteristics are shown in terms of making high-tech cities through information and communication technologies. Under these circumstances, Korea's ubiquitous city (u-city) construction project is receiving attention. An u-city began with the purpose of improving the life quality of city people by providing diverse ubiquitous computing service. However, diverse problems currently arise from operating costs, specialization of cities, and connection with industries in pursuing the project. To develop a u-city successfully, the problems of operating costs and their utilization should be connected with the functions inherent to cities. To solve these problems, this research has studied the u-city service classification system to develop it successfully by means of providing balanced city service through information communication technologies. The usefulness of this research is expected to be very high in terms of analyzing the development stages of a u-city and positioning the future u-city into perspective.
