A Model of User Experience Design Research and Evaluation-Taking the Holiday KTV App as an Example

Abstract

This study will take Holiday, a famous singing venue, as the research object to investigate the service mode of Holiday's mobile app and the usability problems generated by it, and to improve the app interface to improve the logic and aesthetics of the app. The experiment will be conducted in two stages. The pre-test experiment will mainly focus on the original APP, integrate the improvement problems, add fixed operation details and draw up work items, and ask the testers to perform the same work items. After the improvement, we will conduct the post-test with the same work items and recording method. The data from the two phases of testing will be analyzed by performance evaluation method, weighted index and SUS system usability scale. The results of this study showed that the improved Holiday KTV APP not only improved the user's willingness to use and user experience, but also improved the user behavior of Holiday KTV APP, which proved that the optimization of the Holiday KTV interface design and the typical work items of this study had solved the problems of the original Holiday KTV APP.
