Understanding Human-Computer Interaction: System Evaluation and Research Methods

This article explores different approaches to research and evaluation in Human-Computer Interaction (HCI). It breaks down analytic and empirical methods, highlighting how analytic approaches rely on reasoning and analysis, while empirical methods are grounded in observation and measurement. Additionally, it distinguishes between formative and summative research, explaining how formative evaluation occurs early in a project to guide design, while summative evaluation assesses effectiveness after implementation. Understanding these methods is crucial for improving user experiences in technology.
