This paper introduces a framework for product experience that encompasses all affective responses in human-product interaction. The framework identifies three distinct levels of product experience: aesthetic experience, experience of meaning, and emotional experience. Each level has its own underlying process. Aesthetic experience involves the product's ability to delight the senses. Experience of meaning involves assigning personality or expressive characteristics to products and assessing their personal or symbolic significance. Emotional experience involves typical emotions like love and anger, which are elicited by the appraised relational meaning of products. The framework helps explain the personal and layered nature of product experience. The framework is relevant for design practice as it helps designers structure their attempts to 'design for experience,' deliberately influencing the experiential impact of new designs. The paper discusses the importance of affect in various design disciplines, including marketing, ergonomics, and engineering. It also highlights the multidisciplinary nature of design research and the need for a unified framework to facilitate comparisons between experiential concepts. The paper defines product experience as a change in core affect attributed to human-product interaction. Core affect is a general term for all types of subjective experiences that are valenced, involving perceived goodness or badness, pleasantness or unpleasantness. The circumplex model of core affect is used to describe and differentiate between affective states. The paper also discusses the manifestations of product experience, including subjective feelings, behavioral reactions, expressive reactions, and physiological reactions. The paper distinguishes three types of product experience: aesthetic pleasure, attribution of meaning, and emotional response. Aesthetic experience involves the product's capacity to delight the senses. Experience of meaning involves assigning personality or expressive characteristics to products and assessing their personal or symbolic significance. Emotional experience involves typical emotions like love and anger, which are elicited by the appraised relational meaning of products. The paper discusses the relationships between the three levels of product experience, highlighting how they are interconnected and often difficult to distinguish. It also explores how meaning and emotion are related, and how aesthetics and emotion are connected. The paper concludes that the framework provides a structured way to understand product experience and can be valuable for designers in their attempts to 'design for experience.'This paper introduces a framework for product experience that encompasses all affective responses in human-product interaction.
