VK procedure (Tokyo version)

2018-2020. Experimental setup. Rotoscopy animation, biometric stress detection system.

Description and concept:

“VK Procedure (Tokyo version)”, consists of an experimental setup that uses facial recognition techniques, psychology, and applied mathematics in order to measure the tension between honne (private thoughts) and tatemae (public attitude) in a group of Japanese salarymen. The project is composed of an incentive video (rotoscope animation) and a biometric stress detection system. The video tells two stories of failure: in the workplace, from the point of view of men; and in love, from the point of view of women. The video can only be watched by one viewer at a time; simultaneously, the other viewers in the exhibition space can observe the stress levels detected by a computer system on the face of the viewer watching the video.

The stress detection model is partially based on (Gao, Yuce, & Thiran, 2014) and encompasses the contraction and position of the eyebrows, the quantification and measurement of negative emotions (anger and disgust) and the relationship in time between intensity of blinking and ocular aperture (Eye Aspect Ratio: EAR).
