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.

Mentions: We conducted data acquisition experiments, as outlined in Figure 1. In our method, four types of data are acquired before a user watches a horror movie. First, we perform subjective evaluation with the user to determine his or her condition. Then, we measure the eye blinking rate of the user with a high-speed camera for 1 min. In addition, the user is requested to close his or her eyes to minimize external stimuli while measuring EEG and facial temperature for 5 min. Then, the user watches a horror movie for 23 min. To maximize the user’s fear, we performed the experiment while the light is turned off and included the sound effects of the movie. In the last 1 min of the movie, the eye blinking rate is measured again, for comparison with the measurement before watching the movie. After finishing the movie, we ask the user to close his or her eyes, and facial temperature and EEG data are measured again for 5 min. Finally, subjective evaluation is conducted again to check his or her condition after watching the movie.
