Abstract
As you see in weblog pages, recently, recording daily life has become popular. Lifelog records our daily life as a digital data, and they are used as a material for Weblog and Photolog. In this study, we especially pay attention to "emotion"(emotional tag) in our various action records. In our daily life, we often recall our past experience by emotion. We aim to assume the situation in which emotion records as a lifelog, and hoping to design the system of supporting the recall of a past experience. The use of emotional tag is searching a visual data such as photograph and movies which were taken in past. It can be used as a personal time machine.
