Module 6: Task Modeling and Analysis

Task modeling and analysis are crucial for understanding user interactions in Human-Computer Interaction (HCI). This chapter explores Hierarchical Task Analysis (HTA) as a method for decomposing tasks, alongside Engineering Task Models like ConcurTaskTrees (CTT) which provide formal representations of user tasks. Both techniques aim to improve the design of user interfaces by clarifying the relationship between user actions and system responses.
