The paper "Understanding Experience in Interactive Systems" by Jodi Forlizzi and Katja Battarbee explores the critical issue of understanding experience, particularly in the context of design. The authors characterize current approaches to experience from various disciplines and present a framework for designing experiences in interactive systems. This framework is designed to be applied by multidisciplinary teams to understand and generate interactions and experiences in new product and system designs. The paper categorizes approaches to experience into three groups: product-centered, user-centered, and interaction-centered. Each group offers different perspectives on how to understand and design for experience. The interaction-centered approach, which is the focus of the paper, emphasizes the role of interactions between users and products in shaping experiences. The authors introduce a framework that describes three types of user-product interactions—fluent, cognitive, and expressive—and three types of experiences—experience, an experience, and co-experience. These interactions and experiences are situated within a social context, where they are interpreted and shared among users. The framework also highlights the importance of emotion in shaping user experiences and the scalability of experience, where smaller interactions and emotional responses accumulate to form larger, more meaningful experiences. The paper concludes by discussing the role of designers in multidisciplinary teams and how they can contribute to understanding and designing for experience. It emphasizes the need for designers to have a deep understanding of the users they are designing for and to apply knowledge about how people use and make meaning with products. The authors provide examples of research activities that can be used to learn about different types of experiences within the framework, emphasizing the importance of both subjective and objective perspectives in understanding collaborative and social interactions.The paper "Understanding Experience in Interactive Systems" by Jodi Forlizzi and Katja Battarbee explores the critical issue of understanding experience, particularly in the context of design.
