Design, prototyping and construction

Design, prototyping and construction

1. Prototyping

   • Is one manifestation of a design that allows stakeholders to interact with it and to explore its suitability.
     • Choosing alternatives
     • Encourages reflection in design
     • Low fidelity prototyping
       • Does not look like the final product
       • Use very different materials
       • Are simple, cheap and quick to produce
       • Storyboarding
       • Sketching
       • Index cards
       • Wizard of Oz
     • High fidelity prototyping
       • More functionality
       • Developed bye modifying components
       • Technical issues

2. Conceptual Design

   • Is concerned with transforming requirements into a conceptual model
   • Is an outline of what people can do with a product and what concepts are needed to understand how to interact with it
   • Key guiding
     • Keep an open mind but never forget the users and their context.
     • Discuss ideas with other stakeholders as much as possible.
     • Use prototyping to get rapid feedback.
     • Iterate, iterate, iterate.
   • Developing an initial conceptual model
     • Interface metaphors
     • Interaction types
     • Interface types
     • Expanding the initial conceptual model
       • What functions will the product perform?
       • How are the functions related to each other?
       • What information is needed?

3. Concrete Design

   • Using Scenarios
     • As a basis for the overall design
     • For technical implementation
     • As a means of cooperation within design teams
     • Cooperation across professional boundaries
