CHS: Small: Collaborative Research: A Theory of Human Microstrategy Selection and Integration in Human-Computer Interaction

需要更好的科学来预测人们在双重任务环境下如何与新的计算机系统互动，比如在驾驶时操作车载导航系统。现有的心理学理论可以解释这个问题，但没有充分解决许多问题，比如，在许多双重任务的情况下，两个子任务变得如此交织，以至于它们成为一个全新的第三个任务。这个项目将研究人们形成的认知策略，有时是潜意识的，以整合人类的信息过程（如眼球运动和手部运动）。该项目将提供科学理论，可用于分析和改进多任务设置中使用的广泛用户界面的可用性，包括常用的手持设备和车载界面，以及任务控制中心、核电站和急诊室的专用界面。该项目将(a)发展一种人类微策略选择与整合（HMSI）理论，该理论将预测两个任务如何交错，特别强调复杂认知策略的形成；(b)应用HMSI理论作为一种新方法的基础，分析师可以使用该方法将两个传统的分层任务分析（HTA）图（每个任务一个）转换为一组交错的微策略；(c)通过人体实验评估HMSI理论和方法，包括分析人们在驾驶模拟器中与车载导航系统交互时的眼球运动。该项目将推进认知心理学理论，并为解决人机交互问题提供科学方法。

Better science is needed to predict how people will interact with new computer systems in dual-task settings, such to operate on board navigation systems while driving. Existing psychological theory can inform the problem but does not adequately address many issues such as that, in many dual-task circumstances, two subtasks become so interleaved that they become an altogether new third task. This project will investigate the cognitive strategies that people form, sometimes subconsciously, to integrate human information processes (such eye movements and hand movements). The project will provide scientific theory that can be used to analyze and improve the usability of a broad range of user interfaces that are used multitasking settings, including commonly-used handheld devices and in-vehicle interfaces, as well as specialized interfaces in mission control centers, nuclear power plants, and emergency rooms.The project will (a) develop a theory of Human Microstrategy Selection and Integration (HMSI) that will predict how two tasks would be interleaved, with a special emphasis on the formation of complex cognitive strategies, (b) apply the HMSI theory as the foundation for a new methodology that analysts can use to transform two conventional hierarchical task analysis (HTA) diagrams, one for each of the two tasks, into an interleaved set of microstrategies, and (c) evaluate the HMSI theory and methodology with human experiments, including the analysis of the eye movements that people make when interacting with an on board navigation system in a driving simulator. The project will advance a theory of cognitive psychology and provide a scientific approach for solving human-computer interaction problems.
