# Design Strategies for Mobile Click-and-Load Waiting Scenarios
###### Abstract  
The optimization of design strategies in loading and waiting scenarios is of great significance for enhancing user experience. This study focuses on the click-to-load waiting scenario in mobile device interfaces and systematically analyzes the user experience performance of three design strategies--the interface type, loading indicator, and layout--across different page transition types (including the tab page, content page, and half-screen overlay). Based on questionnaire responses and experimental data (N = 90) collected from participants aged 20-29, we assessed subjective user perceptions across five validated metrics: time perception, loading speed, satisfaction, emotional valence, and arousal level. The results revealed significant differences among strategies in terms of loading speed perception, time awareness, and emotional responses. Notably, progressive loading strategies proved particularly effective in enhancing user satisfaction and alleviating temporal cognitive load. This study summarizes the characteristics of strategy applicability and proposes general optimization recommendations, offering both theoretical insights and practical guidance for designing loading feedback in mobile device interfaces. user interface design; loading screen feedback; user experience; wait behavior; hierarchical loading Article

multi-level page transitions, with the aim of providing theoretical support and design guidance for optimizing the loading experience. Page-level click-to-load scenarios refer to the content transition and loading processes triggered by navigation actions (e.g., clicking menus, tabs, or list items) in applications or web pages, typically occurring during the high-frequency, short-duration interactions that follow a user's entry into the system. Users are highly sensitive to the response speed following a click; delayed feedback can easily trigger anxiety and disrupt operations [12]. Against this backdrop, the design of feedback during the click-to-load phase is crucial for maintaining interaction continuity, enhancing the perception of fluidity, and improving overall satisfaction. Visual feedback is commonly employed on loading screens to enhance the quality of user experience [3; 5]. Based on an empirical survey of over 40 mainstream mobile applications (as shown in Figure 1), we identified that users primarily experience four common page-level waiting and loading scenarios: app launch loading, click-to-load, pull-to-refresh, and upload/download processes. As a high-frequency interactive scenario within the page hierarchy, click-to-load--owing to its complex interaction process and sensitivity to time--emerges as a key factor influencing user perception and satisfaction [13]. Furthermore, the page transition structure within the click-to-load scenario is further subdivided into three typical sub-scenarios: tab page transitions, content page transitions, and half-screen overlay pop-ups. Therefore, this study adopts a mixed factorial design of three transition scenarios (tab page, content page, and half-screen overlay) \(\times\) multiple (strategy types) to investigate the effects of the interface strategy, loading indicator strategy, and layout strategy on user waiting experience across different page transition types, and to derive corresponding design strategies. The main contributions of this article are as follows:  
1. Systematically categorizing mobile click-to-load scenarios and clearly defining three typical scenarios: tab page, content page, and half-screen page;
2. Constructing a comprehensive design framework that encompasses interface strategy, symbol strategy, and layout strategy;
3. Employing a multidimensional evaluation system to systematically investigate users' subjective experiences during the click-to-load process, thereby providing a theoretical basis for design practice and assisting designers in optimizing feedback strategies
