2. RELATED WORK Previous research has been conducted regarding the capture of video or photo along with the physiological signals of users. Those researches used physiological signals to support users’ videos. Physiological responses are used to annotate the video and physiological non-response times shorten the video duration [3][4]. Sas et al. [5] used Galvanic Skin Response (GSR), which can measure a user’s emotional arousal, as a photo classifier for organizing life log photos. Their study focused on relationships between a user’s emotional arousal and photos, and showed that high arousal photos, more than low arousal photos, support richer recall of episodic memories. In our research, we focused on using physiological signals to record and share emotional response of video shooters. We used SCL, also known as GSR, for it is shown it has a linear correlate to levels of arousal [10].
