Bottom Line: Further, the latter causes inconvenience to the user due to the sensors attached to the body.Among various emotions, the accurate evaluation of fear is crucial in many applications, such as criminal psychology, intelligent surveillance systems and the objective evaluation of horror movies.Therefore, we propose a new method for evaluating fear based on nonintrusive measurements obtained using multiple sensors.

ABSTRACT
Most previous research into emotion recognition used either a single modality or multiple modalities of physiological signal. However, the former method allows for limited enhancement of accuracy, and the latter has the disadvantages that its performance can be affected by head or body movements. Further, the latter causes inconvenience to the user due to the sensors attached to the body. Among various emotions, the accurate evaluation of fear is crucial in many applications, such as criminal psychology, intelligent surveillance systems and the objective evaluation of horror movies. Therefore, we propose a new method for evaluating fear based on nonintrusive measurements obtained using multiple sensors. Experimental results based on the t-test, the effect size and the sum of all of the correlation values with other modalities showed that facial temperature and subjective evaluation are more reliable than electroencephalogram (EEG) and eye blinking rate for the evaluation of fear.

sensors-15-17507-f016: Ratios of delta band to beta band of EEG data before and after watching the horror movie.

Mentions: Figure 16 and Table 7 show the measured delta band to beta band ratio of each electrode before and after watching the horror movie. As explained in Section 2.3 and shown in Figure 8, we find that the power ratio between delta and beta bands decreases after watching the horror movie. As shown in Figure 16 and Table 7, the delta band to beta band ratio at all electrodes is reduced after watching the horror movie. Whether an electrode shows a significant change before and after watching the movie is based on the p-value of the t-test. The selected O1 electrode has the lowest p-value at 0.1166, as shown in Table 7; however, this is larger than the significance levels of 99% (0.01) or 95% (0.05). Therefore, the EEG signal does not exhibit a significant difference before and after watching the horror movie.
