The influence of user interface design on task performance and situation awareness in a 3-player diner's dilemma game.

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.

Project description:System design is recognized as one of the most critical components of a software system that bridges system requirements and coding. System design also has a significant impact on testing and maintenance activities, and on further improvements during the lifespan of the software system. Software design should reflect all necessary components of the requirements in a clear and understandable manner by all stakeholders of the software system. To distinguish system elements, separation of concerns in software design is suggested. In this respect, identification of the user tasks, i.e., the tasks that need to be performed by the user, is not currently reflected explicitly in system design documents. Our main assumption in this study is that software quality can be improved significantly by clearly identifying the user tasks from those that need to be performed by the computer system itself. Additionally, what we propose has the potential to better reflect the user requirements and main objectives of the system on the software design and thereby to improve software quality. The main aim of this study is to introduce a novel notation for software developers in the frame of UML Activity Diagram (UML-AD) that enables designers to identify the user tasks and define them separately from the system tasks. For this purpose, an extension of UML-AD, named UML-ADE (UML-Activity Diagram Extended) was proposed. Afterwards, it was implemented in a serious game case for which the specification of user tasks is extremely important. Finally, its effectiveness was analyzed and compared to UML-AD experimentally with 72 participants. The defect detection performance of the participants on both diagrams with two real-life serious game scenarios was evaluated. Results show a higher level of understandability for those using UML-ADE, which in turn may indicate a better design and higher software quality. The results encourage researchers to develop specific design representations dedicated to task design to improve system quality and to conduct further evaluations of the impact of these design on each of the above mentioned potential benefits for the software systems.
