Website UI Design Interactivity and Interface Visual Design Based on Improved DFA Algorithm

With the rapid development of the Internet, people rely more and more on network information. As a new means of communication, the interaction design of websites is particularly important. In this process, factors such as page layout, interface elements and colors should be considered. This paper has carried out a large number of related literature research on user browsing experience. By analyzing and summarizing the DFA algorithm model and calculation formula, determine the UI design scheme and implementation process based on the improved method. On this basis, the existing B/S architecture and functional modules are specifically optimized by using software engineering courses, and the overall effect of the website is evaluated by using the theoretical knowledge of interaction design. The evaluation test results show that the website UI design interactivity and interface visual design platform based on the improved DFA algorithm has high compression efficiency, and can design the website UI interface smoothly.
