Mastering the HCI Matrix: Interaction Models, Design Engineering & Case Studies (Part 2)

Welcome back to Part 2 of our ultimate deep dive into Human-Computer Interaction (HCI) for the PCCS AML 302A exam. In this installment, we move beyond biological hardware to decode the engineering frameworks and mathematical models that drive modern software design
.
From the "Gulfs" of Donald Norman to the "Curb-cut Effect" of Universal Design, we break down the high-probability topics you need to crush your 10-mark questions
. We also explore why Google and Gmail are HCI masterpieces and how mobile ergonomics dictates the very size of your buttons
.
🚀 What You’ll Learn in Part 2:
The Interaction Lifecycle: Bridging the Gulf of Execution and Evaluation using affordances and immediate feedback
.
Paradigm Shifts: The evolution from CLI (Recall) to WIMP (Recognition) and the rise of Ubiquitous Computing
.
Engineering the Interface: Why the Iterative Design Process and Scenario-based design are non-negotiable for software engineers
.
The Math of Prototyping: Understanding the Cost of Change Curve and why failing fast on paper saves thousands in code
.
Web & Mobile Masterclass:
The technical difference between Overlays, Inlays, and Virtual Pages
.
Mobile Ergonomics: The "Thumb Zone" and why buttons MUST be 44x44 or 48x48 pixels
.
Scientific Usability: Using Nielsen’s Formula to prove why testing just 5 users finds 85% of your bugs
.
Collaborative Tech (CSCW): How Shannon’s Entropy explains why we need emojis and the Time-Space Matrix for apps like GitHub and Zoom
.
📊 Exam Strategy: The 10-Mark Template We wrap up with a specific template to help you signal rigorous engineering expertise to your examiners—including where to "drop the math" (Fitz's, Hicks, and Shannon's laws) to secure full marks
