For task-centric humanââ?¬â??computer interactions, information display is a crucial element based on which users make their\ndecisions. Since providing more information may not always promote the userââ?¬â?¢s awareness of the situation, we investigate\nthe relationship between information availability and user decision-making characteristics by conducting an experiment\nin the form of a war-simulation game. The results show that different types of operators rely on different types of\ninformation in decision-making. A workflow of adaptive provision of information is also introduced using our conceptual\narchitecture for an adaptive user interface for task-centric in-vehicle applications. A pilot study presented in the article is\nan attempt to add user-oriented design to task-centric in-vehicle operations to meet different requirements of operator\ndecision-making.
