Explain the term widget.
3.0 MAIN CONTENT
3.1 FIDELITY OF PROTOTYPES
This refers to how accurately the prototypes resemble the final design in terms of visual
appearance, interaction style, and level of detail.
The three main fidelity types are:-
Low-Fidelity prototypes
Medium-Fidelity prototypes
High-Fidelity prototype
