Design for mood regulation is an emerging design area that is gaining growing interest. However, there is limited guidance on what designers should consider when creating interventions to support mood regulation. To address this gap, we conducted an exploratory case study focused on the “Sunday Blues”—a common dip in mood experienced at the end of the weekend as the new workweek approaches. We designed WeMo, a system aimed at helping users capture weekend highlights, culminating in a visual summary displayed on Monday. We engaged 15 participants in co-constructing stories around their potential use of the system. Participants expressed frustrations with the system’s features, concerns about its effectiveness, and obstacles to its application in daily life. Based on these insights, we highlight key considerations for designing mood-regulation interventions, such as balancing mood regulation with other fundamental needs, addressing the complex roots of mood, and respecting the acceptance of negative moods. By identifying user concerns and translating them into design considerations, this study provides actionable guidance for practitioners and contributes to the growing body of research in mood-focused design.

This article presents a comprehensive review of existing literature covering the topic of mood-focused design. It delves into how designers and design researchers currently address mood in the context of experience-driven design. Using a scoping review methodology, we identified and thematically analyzed sixty-six highly relevant articles. Our findings are categorized into four themes: (1) diverse features and impacts of mood that have been comprehended and explored in design; (2) mood-focused design innovations that support mood monitoring, expression, and regulation; (3) potential issues and considerations related to mood-focused design; and (4) methodological resources that support empathizing and ideation within a mood-focused design process. This scoping review advances our understanding of mood as a distinct facet of human experience in design and outlines the current state of mood-focused design as an emerging field. To facilitate progress in the field, we propose four avenues for further exploration, underscoring the need to expand mood-centric theoretical understanding, artifact creation, opinion sharing, and method development.
