Background

• Universal accessibility of information
• requires
• Pro-active product development
• Shift from engineering to system design
• Pragmatics and semantics matter
• Individualisation adaptability are crucial
• gtgt Abstract representations

12
Design Knowledge

• User characteristics
• Technology
• Tasks
• Mutual relationships
• diversity of users
• multiple styles of interaction
• changing requirements
• adaptation features

13
Design as a Process

• Transformation of knowledge
• task/object model refinement
• background knowledge
• essential model
• users model
• design
• Decision making
• based on a design space
• transparency and rationale explication
