Heading - Interface Design

What is it?

Interface design is about creating a vision of how your target users will interact with your product. It is a highly collaborative and iterative process in which rough design mock-ups are created for review with users. Through testing and refinement these mock-ups evolve into detailed interaction blueprints which can be used by visual designers and developers as the foundation for their work.

Why do it?

  • Early feedback - Producing rough hand-drawn paper mock-ups provides design feedback early in the development process where changes are simple and inexpensive.
  • Helps maintain focus on high level design - Presenting electronic prototypes or demos too early in the process results in users focusing on the detail as opposed to the more fundamental building blocks of the design, such as structure and navigation.
  • Provides richer user feedback - Users respond better to designs that look "unfinished". They are more likely to give useful feedback if they think you haven't spent much time producing the design.
  • Partnership - Collaborative design sessions give users and developers a valuable role in the design process and facilitate partnerships between the two.


  • Conduct background research
  • Write activity scenarios
  • Brainstorm design and create initial paper mock-ups
  • Conduct collaborative design sessions with users
  • Develop more detailed paper mock-up
  • Conduct usability walkthrough
  • Further refine design
  • Produce design blueprints.

What you get

On completion of the interaction design work, depending on the product, deliverables may include:

  • Activity scenarios
  • Workflow diagrams
  • Paper mock-ups
  • Video recordings of usability walkthrough sessions
  • Detailed interaction blueprints
  • Basic interactive electronic mock-ups/prototypes.
