The Process of Interaction Design

What interaction design involves, the problem space, degrees of user involvement, the user-centred approach, the four basic activities and lifecycle models (simple, Google design sprint, research and design), three key characteristics, and practical issues: users, needs, alternatives and choosing between them.

Degrees of User Involvement

Slide 6: Degrees of User Involvement

Notes

  1. User involvement ranges from full-time members of the team to occasional consultation; involvement manages expectations and creates ownership.

Who are the users / stakeholders?

Slide 19: Who are the users / stakeholders?

Notes

  1. Stakeholders: everyone affected by the product’s success or failure, not only the direct users.

What are ‘needs’?

Slide 22: What are ‘needs’?

Notes

  1. Users rarely know what is possible; find needs by understanding their characteristics and capabilities, what they want to achieve, and how they do it now.
