제품의 심미적·형태적 반영을 고려한 디자인 사용성 평가 제안 : 플라스틱 사출 자전거 디자인 사용성 평가를 중심으로

Background Recently, companies are using Usability Testing to reflect various needs of users in product design. However, it is hard to say that product designers can fully reflect the needs of users in their products only as a result of a general Usability Testing. Thus, it is necessary to conduct an testing that can reflect visual requirements along with Usability Testing. Therefore, the researcher would like to propose the provisional name Visual Pointing, an testing method that includes a visual assessment of the product in the Usability Testing, and confirm its potential. Methods First, we propose Visual Pointing that complements the defect of general Usability Testing from the perspective of product designers. Second, to verify the possibility of Visual Pointing, feasibility is verified through Usability Testing experiments considering aesthetic and morphological reflection of the product. Third, we check the experimental results applied with Visual Pointing to find complementary points and propose an improvement plan. Results With only the results of the general Usability Testing, we confirm that there are some difficulties in suggesting aesthetic and morphological improvement directions for the product to designers. Furthermore, the application of Visual Pointing confirmed that complementary visual evaluations along with general Usability Testing are possible and that aesthetic and morphological results can be more clearly communicated to product designers. Conclusion This study will be meaningful in proposing a provisional ‘Visual Pointing’, a visual evaluation method that complements general Usability Testing, and suggesting the possibility of a complementary Usability Testing through experiments with newly reconstructed evaluation items.
