PRV-based Stress Analysis on VR Display's Light/Color Temperature
Overview
With the interest in VR increases, the number of users and the usage time increases as various contents are developed in virtual environments. In addition to VR, different mobile devices, tablets, PCs, etc., include functions based on display brightness and color temperature control, and there is also an opinion that using VR for a long time can cause eye diseases such as dry eyes and visual disturbance.
This research investigates the effect of VR device display color temperature on human stress in a VR environment. As a result, pulse rate variability parameters in the time- and frequency- domains all showed significant differences between cool white and warm white (dark mode) conditions, and it was confirmed that the LF/HF ratio, known as the parameter most closely related to stress, was observed to be lower in warm white conditions.
Robotic Mood Transition in Patient Robot-based Care Training Environment
Overview
The main purposes of the proposed method in this research are (a) to provide feedback that allows the caregiver to react immediately to the emotions felt by the robot during care training and (b) to propose a way for the caregivers and the robot to communicate their emotions, thereby enhancing the caregivers’ ancillary qualifications such as stability, optimism, and communication.

High-performance Blu]etooth Low Energy System-on-Chip ARM microprocessor is used for pre-processing of measured data and communi]cation with the smartphone.
Patient Robot for Care Training
Overview
A human patient simulator (HPS) can achieve visual-, auditory-, text-, and alarm-based effective feedback methods in care and nursing education. Among these, the method of visual feedback is essential to design an HPS that can express emotions or feelings of pain like an actual human does because this method allows an immediate reaction against a robot and a human. This study aims to develop a visual feedback method for a care training assistant robot that can express pain states in joint care education.
