Research Statement

This study explores the effects of Positive Emotion Regulation (PER) on user well-being and explores how to develop designs that help users' PERs. A person is more emotional than rational, and it influences situational awareness, decision making, behavior, etc. Therefore, there are a lot of studies that study emotional aspects and are being actively carried out the research. Among them, human-computer interaction (HCI) is a study that focuses more on humans than on computer hardware or software, and in areas such as healthcare, various studies have been conducted to help develop products and services that help experience positive emotions to enhance physical and mental health and life satisfaction of the role of emotion.

​

Emotion control is a way to improve users' happiness and refers to the phenomenon in which users control their emotions effectively on their own, in a way that has recently attracted attention in psychology and sociology. The ability to use various emotional control methods in the right place is known to have a positive effect on life satisfaction as well as momentary enjoyment. Based on these existing studies, various studies have recently been conducted to explore the possibilities of behavioral intervention techniques (BITs) that help users control their emotions.

​

​However, while existing related studies suggest the possibility that technology and design can help control emotions, they still draw limits in the systematization of research. For example, there is a lack of explanation for the basic principles applied to the design process or mention of any considerations or the feasibility of the applied technology. Also, the focus of most of the related research is on negative emotion regulation, and systematic exploration of how to develop interconnected products that help users' PERs has yet to be made. Thus, this study aims ultimately to develop and verify theoretical and practical design methodologies and tools that HCI researchers, design practitioners, and students can systematically analyze and design the interrelationships between humans and computers to contribute to the well-being of users.
