Simplicity

The goal to reach Simplicity has been the key point of Human- Computer Interface since 1980s. In this research, we would like to know what Simplicity is and how to reach it. We used case studies to get two factors of Simplicity, which are the information modeling and the experience of perception through senses. Based on the factors, we implemented a prototype to refine the concepts of simplicity. The prototype was a new attempt to consider only the simplicity of HCI. Further research efforts on emotion, creativity, and aesthetics related to simplicity are important.
