실버세대의 모바일뱅킹 어플리케이션 사용성 향상을 위한 UI 디자인 연구

Abstract

Recently, Korea is rapidly entering an aging society, and it is necessary to study mobile banking applications that improve the convenience and accessibility for them. This study analyzed the UI design components for the mobile banking applications of the four major commercial banks in Korea, and conducted usability evaluations through questionnaires and in-depth interviews with 10 people in their 60s living in the Seoul, Gyeonggi area. The results are as follows. The information structure is different in the amount and depth of information, and the layout is vertically long or composed of one page. The icon/button can be divided into two types, which are universal or mainly used in mobile, and can be used alone or in combination with letters. It can be seen that typography is mainly used in Sans serif style and emphasizes important parts or hierarchies in color. The usability evaluation results for this are as follows. It is shown that it feels familiar when it is similar to Internet banking, and that the use of popular icons/buttons helps cognitive ease. It is recommended to increase the level of attention by expressing important buttons in color, and it was found that a layout with lots of margins and too concise would rather cause confusion. When the icon/button and the text description are used together, the function can be intuitively understood, and the size of all elements on the screen must be large enough to recognize the large text setting sufficiently. As a result of this study, it is expected that UI design and usability improvement of mobile banking applications for the silver generation in the future.
