허벅지 부위를 중심으로 피부 기반 입력의 온바디 인터랙션 디자인

Background There is a usability issue for a mobile and wearable device input method and input surface area change. To solve these problems, we propose the use of skin as an input surface onbody interaction method. In comparison with the technical problems, this paper focuses on nontechnical users. The purpose of this study is to extract skin–based gestures from the thigh through a survey and to verify a usability evaluation and a music functions gestures design. Methods We examined the theory of on-body interaction through advanced research and we found that it is worth to study on-body interaction of the thigh. During the experiment, we obtained the on-body interaction gesture of the skin-based input when the 20 participants remained sitting in the laboratory. We defined each gesture separately. We also commented and detected the usability and music functions gestures design through the users’ research and we analyzed the results through the statistic analysis and the interview content. Results Through the experiment, we extracted a total of 11 skin–based input gestures on the thigh. The 11 gestures were found to becorrelated for comfort and social acceptance. The more changes in the surface of the skin made by gesture, the less comfort we feel. If gesture made negative effect on yourself or others around you, the gesture became less receptive. We verified a total of two mapping factors when designing the gestures to music functions. Conclusions We hope that this study will provide users with new experiences and will be studied further in other posture situations. This paper is expected to contribute to the development of on–body interaction research.
