Sketches are often used in the early conceptual stages of the product. Sketch prototypes can express essential interface functions and content layout. Basic sketches such as boxes, circles and some line segments can be used to express product prototypes. The advantage of sketches is that they are low in design cost and can be modified at any time.
The fidelity of the prototype can be divided into low accuracy, high fidelity. Low-fidelity prototypes can help us accurately split the page, as well as the function modules and presentation information of each page, determine the interface layout of each page element, the element layout in the low-fidelity prototype, and the functional modules need to be infinitely close to the product after the product goes online.
The high-fidelity prototype can realistically simulate the final visual effects, interaction effects and user experience of the product. The high-fidelity prototype is also the smallest viable product, with the same visual display and interaction as the real product. High-fidelity prototypes need to be colour-matched on a low-fidelity basis, with authentic images and icon icons inserted.
In the process from low fidelity to high fidelity, many user experience considerations are needed. The first is visual, and visual aesthetics will also affect the user experience to a certain extent. Excellent visual effects can enhance the user’s trust in the product.
From the layout, colour matching, interaction and other details to enhance the user experience, while considering the user’s emotional experience, looking for the user’s comfort point, is the path to low fidelity to high fidelity.
