We also compared the participants’ comments about the impressions they had of each of their videos and the change in their SCL. The result showed the participant who had strong impressions of videos had larger SCL changes than the participant who had weak impressions. Sas et al. [5] also show that high arousal photos do improve the quality of memory more than low arousal ones. Therefore, it is not surprising to see videos also have strong relationships to SCL as an indicator of the shooter’s emotional arousal. Figure 5 shows both participants’ variation of SCL while coincidentally capturing video of the same subject, that is, scenery from a high place. We asked them “Why did you capture this subject?” Participant A said, “It was beautiful scenery” and Participant B said, “I don't have any particular reason”. The signal trace of Participant B in the colored area of Figure5:A shows rapid change. We showed Participant B only the video and asked him for comments about the video from Participant B. Participant B said, “I found birds in the distance when capturing the video”. Participant A’s SCL doesn’t have rapid change despite participant A’s video also had birds. These results show that the SCL is a reflection of the video shooter’s emotional state or reaction. So, we think using SCL to record affective experience of video shooters is very effective. Ways of manually placing tags on videos to represent the shooter’s emotion already exist. Our system can record the reaction do not notice themselves by using physiological response. However, this system used only SCL and these results are based on few participants. We will conduct the study with more participants in future and investigate the variables in representing physiological signals.
