  7. „Your product or service is useless if humans do not understand it, cannot operate it, or do not want to use it.“

  8. Objectives • Learn principles of psychology that form the basis ofuser-centered design • Become an informed observer of people, objects, and how they interact

  9. Donald A. Norman Jakob Nielsen Nielsen-Norman Group www.nngroup.com

  10. 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)

  11. Research Fields • From Man-Machine Interaction (MMI) to HCI, to 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

  12. 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)

  13. Dimensions of Psychology Psychology deals with human experience (i.e., mental processes) and behavior. Mind Thinking Environment Acting Body Feeling

  14. Psychological Disciplines • Cognitive Psychology • Sensation, Perception, and Motor Control • Learning, Memory, and Thinking • Emotion and Motivation • Social Psychology • Developmental Psychology • Personality and Inter-individual Differences • Applied Psychology

  15. The Model Human Processor • Perception system • Cognition system • Motor system (Card, Moran, & Newell, 1983)

  16. Perception, Attention and Memory • Classic cognitive research investigates the laws and limits of human information processing (i.e., knowledge construction), including the capacities and structures in retaining, storing, and retrieving information. • It does not explicate the contents of the mind.

  17. Stage Model of Memory Symbolic information chunks Semantic and procedural information Information modality Unprocessed information organization/elaboration Audible Sensory Storage Working Memory Long-Term Memory Visual Haptic maintenance Decay: 0.2-4s Decay: 20-30s 7 (± 2 chunks) Decay? Interference? Adapted from Atkinson & Shiffrin (1968)

  18. Traffic Psychology Example Ca. 1 sign / 20 m Percentage of driving time used only to visually fixate traffic signs.
