Problem
"There are numerous guides on Web design but for the most part, these are based on designer's intuition and common sense - with little theoretical or experimental validation."
(Dalal et al, 1999)

Human-Technology Interaction and Man-Machine-Man Interaction (MMMI)
• User Psychology vs. Psychology of Use• Consumer Psychology
• From Human Factors and Ergonomics, via Usability Analysis and Evaluation to User Experience Research
• Human(User)-Centered Design and User-friendly Computing
Applying Psychology in Design
– “Design is where the action is, not evaluation” (Newell & Card, 1985)
– Psychology can be “the mother of invention” (Landauer, 1987)
– “Psychologists often relegate themselves to the role of commentators on existing designs, but the alternative is to take the lead” (Draper, 1993)
