In this research review I undertook the problem related to the usage of a new concept known as the Mixed- Fidelity Prototype which is a mixture of its predecessors Low- and High- Fidelity Prototypes in Experience Prototyping. Experience Prototyping is a good way to explore, communicate and interact with the designs we develop like experiencing cycling on the ice, although the mood, snow conditions, bicycle type and many other factors really matter and tend to change with time. Experience Prototyping in itself is a very large domain to be explored separately but this research contains the idea to improve the ways we can achieve these factors with a minimal variation. Prototyping has the involvement of both the users and the stake holders so it is really important that correct experiments and the prototypes should get the desired results. With the effective usage of mixed-fidelity prototype in Experience Prototyping a better understanding of the real system can be developed as it gives a feeling of both the Low- and High- Fidelity Prototypes. It can unable an HCI developer to properly identify the requirements either functional or non-functional as identified by the proposed user. This paper has a comparison study between the uses of different prototyping models in Experience prototyping for better understanding of the system under development in detail and reasons for preferring Mixed-Fidelity Prototypes over the others.
