Which term describes a person's perceptions and responses from using a product, system, or service?

The term that best describes a person's perceptions and responses from using a product, system, or service is user experience. User experience encompasses all aspects of the end-user's interaction with a company, its services, and its products. It includes not only the usability of the product but also how enjoyable, engaging, and satisfying the experience is for the user. This holistic view takes into account factors such as design, functionality, accessibility, and emotional engagement, allowing for a comprehensive understanding of how individuals perceive their interactions.

While user feedback is related to the responses and opinions gathered from users, it serves as a means of gathering information rather than describing the overarching experience itself. User journey refers to the specific steps or stages a user goes through while interacting with a system or product, which is a component of the broader user experience concept. Customer satisfaction, although it relates to how pleased a user is with a product or service, is more about the overall fulfillment of needs and expectations rather than encompassing the entire experience of use. Thus, user experience is the most accurate term in this context.
