What describes the interface that serves as a boundary between users and technological products?

The user interface is the component that acts as a boundary between users and technological products, enabling interaction between the two. It encompasses everything that a user experiences when interacting with a device, application, or software, such as layout, design elements, buttons, and visual cues. The primary goal of a user interface is to facilitate user engagement by providing an intuitive and efficient way for users to navigate and utilize the features of a technological product.

Designing an effective user interface involves understanding user needs, preferences, and behaviors, ensuring that users can easily understand and operate the product without unnecessary complexity or confusion. Hence, the user interface is critical in enhancing user satisfaction and usability, making it an essential aspect of any technological solution.
