A low-fidelity prototype is a rough, inexpensive, and quickly-made representation of a product or system. It is used to test the concept and gather feedback from users, before investing in a more expensive and time-consuming high-fidelity prototype.
A high-fidelity prototype is a more detailed and realistic representation of a product or system. It is used to test the user experience and ensure that the product meets the needs of users.
The main difference between a low-fidelity prototype and a high-fidelity prototype is the level of detail and realism. A low-fidelity prototype is used to test the concept, while a high-fidelity prototype is used to test the user experience.
Here is a table summarizing the key differences between low-fidelity and high-fidelity prototypes:
Feature Low-fidelity prototype High-fidelity prototype
Level of detail Rough and inexpensive Detailed and realistic
Time to create Quick and easy Time-consuming and expensive
Purpose Test the concept Test the user experience
In general, low-fidelity prototypes are used early in the design process, while high-fidelity prototypes are used later in the process. However, there is no hard and fast rule about when to use each type of prototype. The best choice depends on the specific project and the needs of the team.
