Abstract

In addition to functionality and usability, interactive products are increasingly expected to provide pleasurable experiences to their users. Playfulness is a part of these experiences. However, playfulness can manifest in many different ways as humans are inherently playful by nature. This poses challenges for designing for playfulness. To tackle this broad field, we have developed the Playful Experiences (PLEX) framework. The two-fold purpose of the PLEX framework is to be a conceptual tool for understanding the playful aspects of user experience (UX), and be a practical tool for designing for such experiences through established user-centered design (UCD) methods. In this paper we present an overview of our work during 2008--2010 on designing for playful experiences. After introducing and summarizing previous studies, we motivate the reasons for designing for playfulness by framing PLEX within the domains of user experience and emotional experience. Then, we briefly discuss the creation and evaluation of the PLEX Cards and its associated techniques as practical design tools based on the PLEX framework, followed by a concrete design case where these tools have been used. We also present the development of the PLEX Design Patterns for actual design solutions for playfulness. Based on this work, we propose the PLEX framework as a powerful tool for understanding playful experiences, and for providing inspiration to design interactive products that elicit playfulness.
