  1. High fidelity prototyping

  2. High-fidelity prototyping • Uses materials that you would expect to be in the final product. • Prototype looks more like the final system than a low-fidelity version. • For a high-fidelity software prototype common environments include Macromedia Director, Visual Basic, and Smalltalk. • Danger that users think they have a full system

  3. High-fidelity prototyping • Can’t prototype everything • Horizontal: Look and feel of everything, but little functionality • Vertical: Few crucial pieces of functionality

  4. Mobile Hi-Fi – Tools • PC emulator • Supplied by most manufacturers (e.g. Nokia, Microsoft, etc.) • Or create your own (e.g. Flash, Java)

  5. PC – Be Warned • Text input (no keyboards) • Pointing device (no mice) • Portability (limited to lab evaluation) • Performance (PC faster than device) • Custom hardware (mobiles can have hardware not found on PC)

  6. Moving to Implementation • Evolutionary • Tidy up the prototype and release • Rarely a good idea • Revolutionary • Use the prototype as a specification • Re-implement from scratch

  7. Compromises in prototyping • All prototypes involve compromises • For software-based prototyping maybe there is a slow response? sketchy icons? limited functionality? • Two common types of compromise • ‘horizontal’: provide a wide range of functions, but with little detail • ‘vertical’: provide a lot of detail for only a few functions • Compromises in prototypes mustn’t be ignored. Product needs engineering

  8. Construction • Taking the prototypes (or learning from them) and creating a whole • Quality must be attended to: usability (of course), reliability, robustness, maintainability, integrity, portability, efficiency, etc • Product must be engineered • Evolutionary prototyping • ‘Throw-away’ prototyping

  9. Tool support - DENIM
