Design for emotion aims to improve human wellbeing. Design for emotion is a multi-disciplinary or interdisciplinary research field, including art, design, computer science, psychology, education, engineering, and other fields. In the last ten years, there has been an increasing focus on design for emotion in various areas. However, there is no comprehensive literature review to set up a design for emotion research framework. To address this gap, this paper first presents a descriptive review of 66 related papers on this topic and then proposes a research framework for emotional design.
