제품디자인의 심미성요소가 디자인유사성판단의 정확성에 미치는 영향에 관한 실증연구

Background This study is on the effect of the consideration of aesthetic factors on the accuracy of design similarity judgment in the judging similarity of product design. The design similarity judgment considering these aesthetic factors complements the problem of qualitative and subjective similarity judgment based on the existing form, so it is possible to derive an objective and quantitative similarity judgment result, and to improve the accuracy of similarity judgment. Methods In this study, it was proven that the aesthetic factor has a significant influence on the design similarity judgment regardless of the product group, and the consideration of the aesthetic factor in the design similarity judgment has a positive effect on the judgment quality and the improvement of the judging quality. Results Both the form factor and the aesthetic factor increase the accuracy of judgments (average 2.25%) and significantly increases judgment confidence (average 7.87% increase) in comparison with the case of considering design factor only in design similarity judgment. In other words, it was shown that the consideration of aesthetic factors in all product groups improved the accuracy and certainty of judgments to a certain level, and the average of the four groups increased by 7.87% in the assurance of similarity judgment. This is because the consideration of aesthetic factors is a very important factor in judging the similarity of design, and it should be considered as a factor that increases the accuracy of judgment and the assurance of judgment. Especially, since the accuracy of judgment is higher than that of other products in a simple and general-design product group, it is a meaningful research result that aesthetic factors must be considered when judging the design similarity of simple and general-design products. Conclusions The aesthetic factor affects the judgment of design similarity. The aesthetic factors affecting the similarity of product design are proportional, balance, emphasis, harmony, rhythm, unification, and simplicity/complexity. Therefore, when judging the similarity in product design, it is necessary to judge the similarity of both designs by these aesthetic factors as well as morphological judgments. Especially, since the importance of the aesthetic factor (accuracy of judgment) is higher than other product groups in a simple and general-design product group, it is necessary to consider aesthetic factors when judging the design similarity of a simple or general product.
