How is fidelity defined in the context of UX design?

In the context of UX design, fidelity refers to how closely a design prototype resembles the final product in terms of its visual and functional attributes. This concept encompasses both the look and feel of the design, as well as its interactive elements. High-fidelity prototypes often incorporate detailed visuals, realistic interactions, and functionality that closely mimic the user experience intended for the final version of the product. This allows stakeholders and users to visualize and interact with the design more authentically, which can lead to more effective testing and feedback.

The other options touch on various aspects of user experience but do not capture the essence of fidelity. The ease of use pertains to usability, while user satisfaction relates to the overall experience and emotional response to a design. Additionally, feedback from users is crucial in the design process but is separate from the specific definition of fidelity as it pertains to the prototype's accuracy and representation of the final product.
