What requirements do the user interface requirements relate to?

User interface requirements fall under the category of non-functional requirements, specifically usability requirements. They describe how the interface should interact with the user to ensure comfort, intuitiveness, and efficiency of work.

Examples of such requirements:

• Simplicity and clarity of navigation.
• Compliance with design standards and corporate style.
• Interface responsiveness (quick reaction to user actions).
• Accessibility for users with disabilities.
• Support for various devices and screen resolutions.

Thus, user interface requirements aim to improve user interaction with the system and increase satisfaction from using the product.
