Information providing in a task-centric military in-vehicle adaptive human-computer interface based on operator decision-making characteristic

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