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-f019: Comparisons of eye blinking rate before and in the last 1 min of watching the video clip of emotionally-neutral content to the subjects (BR is blinking rate).

Mentions: Figure 19 shows the comparison of eye blinking rate before and in the last 1 min of watching the video clip of emotionally-neutral content to the subjects. For a fair comparison, eye blinking rate is measured as the number of open to closed eyes for a duration of 1 min like the previous experiments for measuring the fear emotion. As shown in Figure 19, the average value (about 17.3) of the eye blinking rate in the last 1 min of watching the video clip was similar to that (about 17) before watching the video clip. However, the average value (about 25.9) of the eye blinking rate in the last 1 min of watching the horror movie was much different from that (about 23.8) before watching the horror movie, as shown in Figure 15. From this, we can find that the difference (about 2.1) between the average values of the eye blinking rate before and in the last 1 min of watching the horror movie is much larger than that (about 0.3) before and in the last 1 min of watching the video clip of neutral emotion.
