Guidelines in HCI
This chapter provides a comprehensive exploration of Human-Computer Interaction (HCI) guidelines, focusing on usability principles and evaluation methods. Key concepts include Norman's Seven Principles, Nielsen's Ten Usability Heuristics, and methods like Heuristic Evaluation and Contextual Inquiry, emphasizing their application in design. Understanding these frameworks enables designers to create user-friendly interfaces and identify usability issues effectively throughout the design lifecycle.

What we have learnt
- Norman's principles enhance user interface design by focusing on discoverability, feedback, affordances, and constraints.
- Nielsen's heuristics provide a toolkit to evaluate usability without extensive user testing.
- Heuristic Evaluation and Contextual Inquiry are critical methods for understanding user interaction and refining designs.
Key Concepts
- -- Discoverability
- The extent to which users can perceive the available actions possible in a system.
- -- Feedback
- The information provided by a system to inform users about the results of their actions.
- -- Affordances
- Properties that suggest how an object can be used or interacted with in an interface.
- -- Usability Heuristics
- General rules of thumb for evaluating the usability of interfaces.
- -- Heuristic Evaluation
- An expert-based usability inspection method to identify usability problems in a user interface.
- -- Contextual Inquiry
- A qualitative research method that involves observing and interviewing users in their natural environment.
