With the explosion of electronic products, including the popularity of mobile devices, people gradually moved from the web to applications. A simple example is that Steve Jobs did not add the Apple Store feature to the first generation of iOS in iPhone 1, but this feature was added to iPhone 3G a year later. This is also due to the needs of users. People began to pay more attention to the “visual effects” and “information showing” that are the main concerns of web design. People found that users have different operating logic and operation methods when using products in different situations. Based on this, designers have identified a design principle: user-centered design concept. At the same time, web design usually focused on a single interface in the past, but with the diversification of user needs and the development of interaction design, UX design began to focus on the entire journey of users from entering the website to leaving. At the same time, with HCI and psychology gradually joining the part of interaction design, people began to try to use the theories of these disciplines to understand user behavior patterns in order to further optimize the interaction logic and journey map of users using products.
