Abstract
To understand the influence of user interface on task performance and situation awareness, three levels of user interface were designed based on the three-level situation awareness model for the 3-player diner’s dilemma game. The 3-player diner's dilemma is a multiplayer version of the prisoner's dilemma, in which participants play games with two computer players and try to achieve high scores. A total of 117 participants were divided into 3 groups to participate in the experiment. Their task performance (the dining points) was recorded and their situation awareness scores were measured with the Situation Awareness Global Assessment Technique. The results showed that (1) the level-3 interface effectively improved the task performance and situation awareness scores, while the level-2 interface failed to improve them; (2) the practice effect did exist in all three conditions; and (3) the levels of user interface had no effect on the task learning process, implying that the learning rules remained consistent across different conditions.
Highlights
With the development and popularization of network and smart devices, people have become familiar with user interfaces (UIs)

Xuan et al used a train simulation driving game to explore the relationship between UI information and task performance, and the results showed that more information did not mean better performance [7]
Summary
With the development and popularization of network and smart devices, people have become familiar with user interfaces (UIs). In the process of human-computer interaction, the interface plays a vital role [1]. A productive and stimulating interface helps ensure high-quality interactions. It is necessary to explain the influence of UI design on human behavior and to set standards to measure the characteristics of interfaces. The 3-player diner’s dilemma game was employed to explore the impact of UI design on task performance and situation awareness (SA). The 3-player diner’s dilemma is a multi-player version of the prisoner’s dilemma, which has been widely applied in research in the economics, psychology, and political science fields [2]. Based on the SA theory and the diner’s dilemma game, we hoped to explore the role of UI design in task performance and SA
