본 연구의 목적은 주차정보 서비스 앱을 중심으로 UX 디자인 방법론을 활용한 앱 디자인 방법을 제시하는 것이다. 자동차는 가장 대중화된 모빌리티 제품으로, 주차공간의 부족으로 인하여 많은운전자들이 주차정보 서비스 앱을 활용하여 필요한 주차정보를 얻고 있다. 사용자를 총족하는 스마트폰 앱을 디자인하기 위해서는 다양한 사용자의 경험을 체계적으로 고려하는 것이 중요하다. 이를 위해 앱 디자인 과정에서 UX 방법론을 체계적으로 적용하였다. 사용자의 요구사항들을 발견하기 위하여 사용자분석, 태스크분석, 컨텍스트분석, 기술분석이 진행되었다. 그리고 분석된 결과를 반영하여 컨셉디자인, 스트럭쳐 디자인, 인터랙션 디자인, 인터페이스 디자인 작업이 수행되었다. 마지막으로 디자인된 앱의 사용자경험을 평가하기 위하여 프로토타입을 개발하였고, SUS 방법, magnitude estimation 방법, 그리고 다기준 사용자경험 평가 방법을 활용하여 기존의 주차정보 서비스앱과의 사용성과 만족도, 그리고 사용자경험을 비교평가하였다. 평가 결과, 본 연구에서 디자인된 주차정보서비스 앱이 기존 앱과 비교하여 더 높은 사용성과 만족도, 그리고 사용자경험을 제공하고 있는 것이 확인되었다. 향후 본 연구의 결과는 다양한 앱의 디자인을 위한 방법론으로 활용될 수 있다.
Abstract
This study was carried out to propose app design methods and examples using UX design methodology, focusing on parking information service apps. Car is the most popular mobility product, but due to a lack of parking spaces, many drivers are using parking information service apps to obtain necessary parking information. It is important to satisfy the user experience of various users. To this end, UX methodology was systematically applied in the app design process. User analysis, task analysis, context analysis, and technology analysis were conducted to discover user requirements. And concept design, structure design, interaction design, and interface design were performed by reflecting the analyzed results. Finally, a prototype was developed to evaluate the user experience of the designed app, and the usability and satisfaction with the existing parking information service app were compared and evaluated using the SUS method, magnitude estimation method, and multi-criteria UX evaluation method. The result revealed that the parking information service app designed in this study provides higher usability, satisfaction, and UX compared to existing apps. This study can be used as a methodology for designing various apps in the future.
