Keyboard의 사용만족도에 영향을 주는 감성 및 설계요소에 관한 연구

Since the introduction of PCs, a keyboard, one of the most common input devices, has been studied primarily in terms of usability. Nowadays, the elements that can stimulate human emotions are getting more attention. Therefore, this study explored the emotions and design factors affecting user satisfaction of the keyboard. We selected 12 pairs of emotional vocabularies related to the tactile feedback among the various emotional factors. Also, six common design elements of the keyboard were extracted. We then quantified the relationship between emotion and user satisfaction using regression analysis and explored the relationship between design and emotional factors through correlation coefficients. Finally, we derived major design factors that affect user satisfaction through Quality Function Development (QFD) method. As a result, we were able to bring coolness, refreshing, familiarity, comfort, and firmness as the main emotions. In addition, the pressure point force, reset point, actuation force, and key trigger travel were derived as the main design factors.
