User experience (UX) refers to a person’s emotions and attitudes about using a particular product, system or service. It includes the practical, experiential, affective, meaningful and valuable aspects of human-product interaction.
Some key aspects of UX include:
- Usability – How easily users can accomplish tasks like navigation, searches and purchases.
- Usefulness – Whether the product helps users meet their needs and achieve goals effectively.
- Desirability – The visual aesthetic and interactive qualities that motivate users.
- Findability – How discoverable desired content and functions are.
- Accessibility – Allowing all users to perceive, understand, navigate and interact with the product.
- Emotion – How the product makes users feel through inspiring, engaging or satisfying interactions.
Good UX design aims to optimize all of these factors to create positive emotions and increase user satisfaction, conversion, retention and advocacy over the lifespan of use. User research helps understand needs and metrics provide feedback.
