고령자 중심의 직관적 인터랙티브 기반 앱 인터페이스 디자인 연구

Abstract

In the context of the mobile communication era, mobile internet has become an essential part of daily life. In the China's application market, the usage rate of apps by the elderly has also increased significantly. However, due to the special characteristics of the elderly group, they also appear to encounter various difficulties when interacting with smartphones. Therefore, this study investigates the concepts and principles of the intuitive interaction theory by taking the top three shopping apps (Pinduoduo, Taobao, and Jingdong) with the highest usage rate of elderly users as the research objects, and deduces the three intuitive interaction principles (familiarity, similarity, and consistency) that are suitable for the app interface of elderly users, based on the current situation and problematic points of using apps by elderly users and the key factors to be considered when using them. Based on the results of the case study, we propose the improvement direction of the app interface for the elderly. From the three aspects of familiarity, similarity, and consistency, the specific improvement plan of the app interface is discussed. First, familiar symbols or text are placed in places where elderly can easily see them, applications without previous experience are designed based on elderly' existing habits, and common features are found among the same type of applications to identify problems of elderly and derive improvement points. Secondly, we examine whether similar functions among multiple applications are implemented in the same way in other applications, and provide service functions that are familiar to elderly and have experience with similar services. Third, the consistency of interface and functionality was increased by aligning various facet functions, locations, and visual elements within the same application with the rest of the design. It is hoped that this improvement can increase the mobile phone usage rate of elderly users and help the elderly better integrate into the current digital life.
