Techniques for Implementing Prototypes
Verbal prototyping: verbal description of choices and results.
Paper mock-ups: printouts or sketches of screen designs.
Wizard of Oz: human expert operating behind scenes.
Fake data: similar data, images instead of video, etc. Simple algorithms: ignore special cases.
Prototyping tools: e.g. HyperCard, ToolBook.
UIMS (User Interface Management Systems): interactive interface builders such as Visual C++.
