As part of the Dutch national science program "Professional Games for Professional Skills" we developed a stress-exposure biofeedback training in virtual reality (VR) for the Dutch police. We aim to reduce the acute negative impact of stress on performance, as well as long-term consequences for mental health by facilitating physiological stress regulation during a demanding decision task. Conventional biofeedback applications mainly train physiological regulation at rest. This might limit the transfer of the regulation skills to stressful situations. In contrast, we provide the user with the opportunity to practice breathing regulation while they carry out a complex task in VR. This setting poses challenges from a technical - (real-time processing of noisy biosignals) as well as from a user-experience perspective (multi-tasking). We illustrate how we approach these challenges in our training and hope to contribute a useful reference for researchers and developers in academia or industry who are interested in using biosignals to control elements in a dynamic virtual environment.
作为荷兰国家科学项目“专业技能的专业游戏”的一部分，我们为荷兰警方开发了一种虚拟现实（VR）中的压力暴露生物反馈训练。我们旨在通过在一项要求苛刻的决策任务中促进生理压力调节，来减少压力对表现的急性负面影响以及对心理健康的长期影响。传统的生物反馈应用主要在休息时训练生理调节。这可能会限制调节技能向压力情境的迁移。相比之下，我们为用户提供了在VR中执行复杂任务时练习呼吸调节的机会。这种设置从技术角度（对嘈杂生物信号的实时处理）以及用户体验角度（多任务处理）都带来了挑战。我们阐述了在训练中应对这些挑战的方法，希望能为学术界或行业中对使用生物信号控制动态虚拟环境中的元素感兴趣的研究人员和开发者提供有用的参考。
