터치스크린 키오스크의 유니버설 설계 지침 개발: 화면 크기 및 화면설계요소를 중심으로 = Development of Universal Design Guidelines for a Touchscreen Kiosk: Focused on Display Size and Graphical Design Components

다국어 초록 (Multilingual Abstract)

Objective: This study aims to develop universal design guidelines for touchscreen kiosks that can be comfortably used by various users such as wheelchair patients and elderly people.
Background: The use of touchscreen kiosks in customer service has been increased; however, various usability problems with the kiosk have been reported.
Method: A literature survey and expert review were conducted to draft the universal design guidelines for touchscreen kiosks; then, a prototype of the kiosk for a fast-food restaurant was built by applying the design guidelines, and its usability was evaluated by comparing it with an original interface for the kiosk of that restaurant.
Results: The revised kiosk design showed better usability than the original design regarding performance time, number of screen touching, number of mistakes and errors, task success rate, and subjective satisfaction.
Conclusion: The universal design guidelines for touchscreen kiosks are proposed based on the results of the usability evaluation conducted in this study.
Application: The proposed design guideline can be applied to the development of various touchscreen kiosks providing good usability to a wide range of users including wheelchair patients, elderly people, and children.
