IB Design Technology Topic A2.2: Prototyping Techniques Key Definitions

A high-fidelity, non-functional model used to represent the final appearance.

A technology that overlays digital information or models onto the real world, usually through a phone, tablet, or AR glasses.

A structured list of all components, parts, and materials, often including quantities, part numbers, and descriptions.

CAD (Computer Aided Design) refers to the use of computer software to create, modify, and communicate design ideas with precision.

The use of software to assist in the design process, allowing for precise and efficient creation of digital models.

Virtual representations of human bodies used to simulate real users interacting with a product or environment.

A computerised simulation method that breaks down a model into small elements to analyse how it responds to physical forces.

Technology that simulates the sense of touch by applying vibrations, forces, or motions to the user.

Detailed, realistic models that closely mimic the look, feel, and functionality of the final product. Can be digital (interactive) or physical (functional).

A functional prototype fitted with sensors or measurement tools to collect data.

Simple, quick, and inexpensive representations of a product. Often made using paper, cardboard, or rough digital sketches.

A rough or basic model, often made from inexpensive materials, used to explore form or function quickly.

A technique that records human movement using sensors or cameras to apply realistic motion to digital models.

A tangible, real-world model of a product, built using physical materials.

Prototyping is the process of creating a model or early version of a product to explore ideas, test concepts, and gather feedback before final production.

Rapid prototyping is the use of 3D printing and other additive techniques to quickly create physical models from CAD designs, allowing fast testing and feedback.

A proportionally scaled-down (or up) version of the product, often non-functional.

Virtual prototypes are digital models created using software tools like CAD (Computer-Aided Design) and simulation programs.

A fully immersive digital environment where users can interact with a 3D model or simulation using a headset or interface.
