3.3 Flashcards
What is a physical model?
A 3D, tangible representation of a design
What are scale models?
A model that is either a smaller/ larger physical copy of an object
Features of a scale model
Accurate physical representation of a design
Used when it is financially/ practically impossible to test a full-scale model
What are mock-ups?
A scale or full size representation of a product with some functionality used to gain feedback from users
What are aesthetic models?
A model developed to look and feel like the real product
Features of prototypes?
Is functional
Test and refine specifications
Discover manufacturing complications
Gain feedback from user trials
Features of aesthetic models
Not functional
Evaluating visual appeal from users
Evaluate the properties of a material (weight, balance, texture, surface qualities)
Expensive to produce
Features of mock-ups
Some functionality (used as a prototype)
Test ideas and gather feedback
Full scale/ scaled models
What are prototypes?
A sample/ model built to test a concept or to act as an object to be replicated or learned from
What is fidelity?
The degree to which a prototype is exactly like the final product
Characteristics of low-fidelity prototypes
Conceptual representation
Not tangible
Characteristics of mid-fidelity prototypes
Communicates some functions of the design
Characteristics of high-fidelity prototypes
Close representation of the final product
Tangible and testable
What are instrumented models?
Prototypes that are equipped with the ability to take measurements to provide accurate quantitative feedback for analysis
Advantages of physical models
Explore and test ideas
Its tangible
Used in user trials
