Empathy has been studied to reinforce in social cognition and social behavior. According to research, bio-behavior synchrony is the clue to enhance the social behavior. Especially, Cardio vascular response that is internal response from bio-behavior synchrony has been connected to social emotion in this study. The purpose of this study was to determine the HRP(heart rhythm pattern) predicting empathy through two person interaction. The 20 subjects (10 females) was participated in study and conducted the interaction tasks. The tasks were categorized the two conditions. One task was to mimic the facial expression by leader (empathy), other was by self (non-empathy). The facial expression in task was included the Ekman`s 6 basic emotions (Happy, Sad, Fear, Disgust, Surprise, Anger). In experiment result, the empathy condition was higher correlation between leader and follower rather than non-empathy condition. Also, the difference of SDNN between leader and follower was significantly decreased in empathy condition. We found that the empathy state was higher synchronization of the heart rhythm, and that is, it was the closer social distance.
Inverse conversion algorithm for an all-optical depth coloring camera

<P>Three-dimensional (3D) metrology has received a lot of attention from academic and industrial communities due to its broad applications, such as 3D contents, 3D printing, and autonomous driving. The all-optical depth coloring (AODC) camera has some benefits in computation load since it extracts depth information of an object fully optically. The AODC camera represents the depth of the object as a variation of wavelength, and spectroscopy is generally required to measure the wavelength. However, in the AODC camera, the color vector in RGB color space is convertible inversely into the wavelength after projection on the normalized rgb plane because the detected spectrum through the gating part has a narrow bandwidth as a result of the width of the slit in the projection part. In this paper, we propose an inverse conversion algorithm from RGB color to depth without spectroscopy. Experimental results are presented to confirm its feasibility. Also, some practical limitations are discussed, resulting from the nonlinearity of the response of the image sensor and the widths of the slits in the projection part and the gating part.

We found that the empathy state was higher synchronization of the heart rhythm, and that is, it was the closer social distance. Using the biofeedback to predict the social emotion especially focused on empathy, Heart rhythm is the indicator to evaluate empathy grade quantitatively. Mapping with heart rhythm would be expected to improve social cognition and enhance relationships.
