  • How do we design it?
  • How do we build it?
  • How do we evaluate what we have designed and built?

 

Early design approaches:

  • Requirements/data gathering:

–User analysis (know your user)

– Task analysis

– Environment/domain Analysis

– Data collection Methods: e.g. interviews, questionnaires, focus groups, observation

  • Conceptual design

– Description of what the system should do and look like

  • Physical design

– Considers the physical details of the system

How do we build it? – Prototyping techniques

– Low-fidelity prototyping (sketches and paper prototyping) » Sketches, storyboards, scenarios, etc

– High-fidelity (digital) prototyping » Using development tools

» Almost the final product

– Native prototyping

How do we evaluate what we have designed and built?

– Evaluation techniques such as:

  • Heuristic evaluation

– Nielson’s 10 heuristics

– Shneiderman’s 8 golden rules

  • Usability test
