Physiological sensing of virtual reality (VR)-induced stressors are increasingly utilized to improve human training and assess the impact of gaming difficulty-induced stress on a person's health and well-being. However, the prior art sparsely explores the multi-level cardiovascular dynamics for psychophysiological demands in a VR environment. This treatise discusses the experimental findings and physiological interpretations of various heart rate variability (HRV) metrics extracted from 31 participants during a Go/No-Go VR-based shooting task across multiple timeframes. The VR-shooting exercise consists of firing at the enemy targets while sparing the friendly ones for different shooting difficulty levels: low-difficulty and high-difficulty with in-between baselines. Ex-perimental results demonstrate consistent shooting difficulty-induced stress patterns at multi-granular levels in response to the heterogeneous inputs (exogenous and endogenous factors). The physiological interpretations highlight the intricate inter-play between cardio-physiological components: sympathetic and parasympathetic response across multiple timescales (sessions and blocks) and shooting difficulty levels.
虚拟现实（VR）诱发压力的生理感知正越来越多地被用于提高人类训练水平，并评估游戏难度诱发的压力对个人健康和幸福感的影响。然而，现有技术很少探讨 VR 环境中针对心理生理需求的多层次心血管动力学。本文讨论了从 31 名参与者在基于 VR 的射击任务中的各种心率变异性（HRV）指标的实验结果和生理解释，该任务跨越多个时间框架。VR 射击练习包括向敌方目标开火，同时为不同的射击难度级别（低难度和高难度）保留友方目标，同时还有中间基线。实验结果表明，在不同的时间尺度（会话和块）和射击难度级别下，针对异构输入（外源性和内源性因素），在多粒度水平上呈现出一致的射击难度诱发的压力模式。生理解释强调了心血管生理成分之间的复杂相互作用：多个时间尺度（会话和块）和射击难度级别的交感和副交感反应。
