Understanding users
• Who: Actors, users, end-users, stakeholders,
customers…..
• Context, situation, location, activity….
• Technologies in use, networks, platforms
• Participatory design, user centered design, codesign
• Interviews, questionnaires, focus groups,
observations
Design/prototyping

users activities
• Lo fidelity/high fidelity – horizontal/vertical
• What is a prototype?
– Technical feasibility of xxx
– Exploration of xxx
– Communication with the user about xxx
