감정에 따른 라이프로깅 데이터의 시각화 연구 -다이어리 애플리케이션을 중심으로-

Abstract

Smartphone penetration rates are continuously increasing globally. These devices deeply influence our lives due to the emergence of various sensing techniques and applications. Large quantities of data are stored and managed by smartphones daily. This data is sometimes mediated by users. We examine the current state of technology in the context of recording experiences. In the past, human sensory organs such as eyes, ears, and hands were the primary means for acquiring and recording information. This is now being replaced by the use of smartphones. Recording experiences has become easier now that this huge amount of information can be more conveniently acquired and recorded simultaneously by various smartphone applications and sensing techniques. This information can be managed automatically using different applications. As a result, the authors of this study have determined that further investigation into methods for classifying and expressing user emotion information recorded by smart sensors is needed. Hence, we propose a method to aid the visualization of records of user's daily lives based on emotion information provided by smartphones. This article proposes an emotional diary interface capable of extracting user emotion data from the information stored on a smartphone. We also discuss how to manage and interpret such information based on the user's heart rate. It is expected that user information can be interpreted based on emotions that have not been focused on until now and that this information may provide clues towards extracting emotional information meaningful to users from countless other stored data.
