Product experience is an academic concept investigating the holistic, longitudinal user engagement with a product across its entire lifecycle. It encompasses all touchpoints, from initial discovery through ongoing usage, and focuses on the comprehensive cognitive and affective responses elicited by these interactions. As a research field, it analyzes how product features, performance, and surrounding interactions collectively shape user perceptions, feelings, and overall value realization, distinguishing itself from narrower focuses like usability by prioritizing the full emotional and experiential journey.
