Overview• Understanding users

– Concepts– Methods

• Design/prototyping– Concepts– Methods

• Evaluation– Concepts– Methods

Understanding users

• Who: Actors, users, end-users, stakeholders, customers…..

• Context, situation, location, activity….• Technologies in use, networks, platforms• Participatory design, user centered design, co-

design• Interviews, questionnaires, focus groups,

observations

Design/prototyping

• Based on understanding both technology and 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– Testing of idea xxx

Structure - alternative

• Introduction– What is the question, wondering….

• About the user/activities/requirements/needs• About the prototyping/design/construction• About the evaluation• Conclusion– What did we find

Content

• What is the question (or problem, or hypothesis)

• In what way did we investigate the quesiton?• What did we find?

Evaluation

• Usability goals/dimensions• Laboratory – or in actual use context• The proof of the pudding is in the eating• Ahhaaaa, (not everybody use the application

the same way….)

Technology - ecology

• Applications/services – app storeS/native/• Networks– Capacities– Coverage

• Terminals– OS– Languages– Interaction
