Gestalt psychology believes that when objects get too close, consciousness will think that they are related. In interaction design, the submit button will be next to the text box. Therefore, if the adjacent functional blocks are not related, there may be a problem with the interaction design.

2. The principle law of 2.ui interaction design Teyssler's law (the law of conservation of complexity).

The law holds that every process has its inherent complexity. There is a critical point, beyond which the process cannot be simplified. You can only transfer the inherent complexity from one place to another. For example, for the design of the mailbox, the recipient address cannot be simplified, but for the sender, the complexity can be conveyed through the integration of the client.

3. The principle of ui interaction design and the principle of error prevention.

Dislocation principle: most accidents are caused by design negligence, not human negligence. Errors can be reduced by changing the design. This principle was originally used in industrial management, but it is also suitable for interactive design. For example, USB slots often appear in the interface interaction design of hardware design. For example, when it does not meet the use conditions, it is often indicated by function failure (in general, the button is grayed out and cannot be clicked) to avoid not pressing it.

When the message box has no content or the email format is incorrect, the verification code cannot be obtained, only when both are satisfied.

If you are interested, you can find other principles of ui interaction design, such as steering law, Gutenberg diagram law, Pareto law with strong applicability (80/20 principle), trichotomy principle and so on. I won't give examples here. There will be more design skills and information about various categories of ui design in the future. You can click on other articles on this website to learn.
