Preface

Through one of the greatest inventions during the twentieth century-computer, it is believed that computers have become the mainstream tool in the engineering industry.

However, computers could only be applied to deal with data and information management at the beginning; then followed by copying knowledge management and human-computer interface, and all of them are related to the intellectual field development. Nevertheless, with the arriving of the twenty-first century, the current trend of computer research not only focuses on intellectual field, but also heads for the kansei aspects. Therefore, establishing the basic kansei theory has become the implication for future research.
