Which human-computer interaction tools can be used in analysis?

• A. Cognitive walkthrough and heuristics
• B. SQL query optimization
• C. Data backup methods
• D. Server deployment

Answer: (A)

Evaluating how people interact with a system uses methods that focus on usability and the user’s cognitive process. Cognitive walkthrough guides you through typical tasks from the user’s perspective to discover where learners might stumble or where actions aren’t intuitive. Heuristics evaluation applies established usability principles to systematically spot problems in the interface, such as unclear feedback, inconsistent controls, or error-prone flows. Together, these HCI analysis tools help you assess and improve how users interact with the system.

Options like SQL query optimization, data backup methods, or server deployment are about performance, data protection, and infrastructure, not about analyzing user interaction or usability, so they don’t fit the context of HCI analysis.
