What aspect does user experience aim to improve?

User experience (UX) is primarily concerned with how users feel and perceive their interactions with a software product. This encompasses various elements such as usability, accessibility, and overall satisfaction. By focusing on the emotional response and the ease of navigation within the software, UX aims to create a positive and effective experience for users, encouraging them to engage more fully with the product.

This approach helps ensure that users not only find the software functional but also enjoy using it, which can lead to increased user retention and loyalty. Improving user experience means considering feedback from users and continually refining design elements, workflows, and functionalities to better meet their needs and expectations.

The other aspects mentioned in the other options, such as backend processes, visual design alone, or performance metrics, while they are important components of software development, do not directly address the holistic experience of interacting with the user interface from the user's perspective.
