In 2014, we will consider safety when experiencing a virtual disaster, and in 2014 we will develop a system to evaluate emotions during the experience in order to prevent mental disorders when experiencing a disaster. This method uses two evaluation systems, a subjective evaluation method and an objective evaluation method, to prevent failures from occurring. Subjective evaluation is a psychological evaluation method that uses the evaluation parameters of Self Assessment Manikin and is evaluated by a preliminary questionnaire before the experience. In addition, objective evaluation is a system that uses biosensing to acquire data on the biological reactions that appear in the body during the experience and evaluates the changes before and after the experience.
When biosensing, which is objectively evaluated, was tested in a virtual environment in 2014, various issues were found. The use of brain waveform, blood flow measurement devices, pupil measurement devices, sweat detection sensors, etc. were considered, but it was determined that sweating is difficult to stably detect and electroencephalograms are expensive and difficult to use. We will test the measurement and method of measuring the pupil using image processing. Blood flow measurement requires data to be acquired while removing noise. The major issue is that biological reactions appear 2 to 20 seconds after the sensation. There are many challenges, but if we create a system to evaluate emotions, we can safely experience negative emotions by adjusting the sensory stimulation of the body according to the evaluation results.
