Dialog Design
This module presents the intricate art and science of dialog design in Human-Computer Interaction (HCI). It emphasizes the significance of formal methods, such as Finite State Machines (FSMs), Statecharts, and Petri Nets, in structuring interactions to improve reliability and usability. The discussion includes the advantages these formalisms provide in terms of precision, automating tool support, and effective communication among stakeholders while also addressing their inherent limitations when scaling to complex interactive systems.

- Importance of formal methods in ensuring robust dialog systems and mitigating user input errors.
- Comparison of FSMs, Statecharts, and Petri Nets regarding their respective strengths and limitations in modeling interactions.
Key Concepts
- -- Finite State Machine (FSM)
- A computational model represented by states and transitions that describe the behavior of interactive systems during the user dialog.
- -- Statecharts
- An extension of FSMs that introduces hierarchical state representation and concurrency, facilitating the modeling of complex interaction flows.
- -- Petri Nets
- A mathematical modeling tool suited for representing concurrent processes and resource sharing in interactive systems.
- -- Formalisms
- Structured methods providing rigorous and unambiguous representations of system interactions to aid in design, verification, and documentation.
