Central to the present paper is the question of how designers can be supported to deliberately facilitate positive emotional experiences. Related to this, the paper provides an overview of the research on design for positive emotions, its issues, and opportunities for further investigations. The practical relevance of transcending the notion of generalised pleasure is discussed, highlighting the benefits of developing and applying a nuanced understanding of positive emotions. Overarching challenges and opportunities that underlie in stimulating such understanding are delineated along with the review of characteristics of positive emotions. Ethical issues of designing for positive emotions are reflected regarding its implications for well-being with suggestions to resolve them. Besides, the paper discusses emerging research directions, ranging from design tools to distinguish diverse positive emotions, the added value of exploring expressive interaction qualities of positive emotions, to advantages of involving tool users (e.g., designers and project stakeholders) in the development process.
