The user interface (UI) layer is part of an application or system that allows users to interact with it and provides visual feedback to the user. It is the layer that sits between the user and the underlying functionality of the system, and it is responsible for managing the user’s interactions with the system and providing a user-friendly and intuitive experience.
User Interface Layer typically includes elements such as:
Graphical User Interface (GUI): This is the visual part of the system, and it includes elements such as buttons, text fields, and drop-down menus that allow the user to interact with the system.
Navigation: This refers to how the user moves through the system, and it includes elements such as menus, breadcrumbs, and links that allow the user to access different parts of the system.
Feedback: This refers to how the system provides visual feedback to the user, and it includes elements such as status messages, loading indicators, and error messages that inform the user about the state of the system.
Input validation: This refers to how the system verifies the input provided by the user. It includes elements such as error messages and form validation that help ensure that the user provides the correct type and format of data.
The UI layer is designed to be intuitive and easy to use and should be optimized for the specific needs of the users. The design of the UI layer is usually based on user interface design principles and guidelines. The UI layer must also be tested with representative users to ensure that it is user-friendly and easy to use.
