사용성 향상을 위한 스마트폰 인터페이스 디자인 연구 -제이콥 닐슨 사용성 원칙을 중심으로-

초록

With the development of information and communication and science and technology, smartphones are daily necessities that perform various activities such as communication and entertainment, but on the other hand, the development of science and technology does not provide everyone with a pleasant experience of use. Based on this background, this study conducted an empirical study to first understand the basic concepts of smartphone interface and usability, secondly, to derive items to evaluate factors that affect smartphone interface usability, and to present improvement directions. The scope of the study was set for Samsung and Apple brands with high sales in the first quarter of 2022, and Think Aloud experiments, user satisfaction surveys, and interviews were conducted on the basic functions of smartphones and differences in operation of the two products. The results show that usability, in addition to optimizing some details that can be quickly and easily manipulated, also affects the layout and feedback area of the interface depending on the function. Through these studies, it is intended to prove the importance of smartphone interface design, present design improvement measures, and help establish strategies by revealing factors to consider when producing smartphone interfaces.
