High Fidelity Mockup. This level of fidelity can be considered as being pixel perfect. Studies show that interactive hi fi wireframes get faster response times from users and ultimately provide more accurate and effective product feedback.
The ideal solution is a high fidelity screen mockup. It behaves and acts just like the final website app product so it is ideal to be used to test for potential app problems before moving into the development stage. You can see the level of design detail we include in our high fidelity landing page mockups over at uxpin.
In other words a mockup that includes some of the most crucial interactions the finished product will have.
The high fidelity prototype known as high tech high fi or hi fi prototype is a comprehensive and interactive prototype that is quite close to the final products with lots of functions interactions and details. High fidelity and low fidelity prototyping low fidelity prototypes are often paper based and do not allow user interactions. A model that works just as if it were the real website or mobile app reacting and interacting with the user. On the other hand high fidelity prototypes are highly functional and interactive.
