The definition of user experience

• "User experience is not how a product itself works, but how the product connects and functions with the outside world, that is, how people touch and use it."

• "The real product form is definitely not determined by the function, but should be determined by the user's own psychological feelings and behaviors."

• "User experience design usually solves the comprehensive problem of the application

The above is Jesse's definition of user experience. User experience can be generally understood as: users use a product in a specific environment to solve practical problems more efficiently. The process involves people (users), tools (products), and problems (application environments), where people are dominant, tools serve people, and solve specific problems in specific environments.

2. Five levels of user experience elements

From bottom to top they are (from abstract to concrete):

• Strategic layer: user needs outside the enterprise + product goals inside the enterprise;

• Scope layer: functional specifications of functional products/content requirements of information products;

• Structural layer: interaction design of functional products/information architecture of information products;

• Framework layer; information design + interface design of functional products;

• Presentation Layer: Create the perceived experience for the product: (usually) Visual Design

2.1 Strategic layer

2.1.1 Conceptual Analysis

There are two basic questions that the strategy layer needs to answer first:

• What are we going to get with this product?

• What do our users get with the product?

Among the above two problems, the first problem comes from the positioning of the product within the enterprise - that is, the product goal, which can also be understood as the business goal or business driving factor of the enterprise. The second problem comes from outside the enterprise—that is, user needs.

For a commercial company, the fundamental and ultimate purpose of any action is to bring profit to the company. However, the business behavior of different companies is different, that is, the strategic positioning of the company is different. According to the different strategic positioning of the company, the corresponding product positioning and the user groups for the product are also different. So product goals (or business goals) can be understood as the company's strategic positioning.
