The departments Neuromotor Behavior and Exercise, Movement Science and Sport Psychology of the Institute of Sport and Exercise Sciences of the University of Muenster apply for Major Research Instrumentation to study human locomotion in an interactive virtual environment with real-time motion capturing and online feedback. Previous studies gained seminal knowledge of human locomotion under laboratory conditions, such as age-related changes in movement parameters or in certain patients. However, the transfer of laboratory results outside to the real world is still a significant scientific challenge. Advances in technology, such as virtual reality (VR), offers an innovative approach to improve the ecological validity of studies. The applied instrumentation consists of a 180° projection-based VR environment, with a surround sound system, and an implemented multifunctional treadmill with integrated force plates, all of which is synchronized with the VR. The instrument is complemented by a high-resolution motion capturing system using infrared cameras, and wireless electromyography. Together, the motion capturing system and the force plates build the interface to interact with the VR and the treadmill (e.g., self-paced mode). The instrument provides a unique setting for the applicants to study the complex interactions between sensory, motor, and cognitive systems during human locomotion under realistic, but still well standardized and safe experimental conditions. It offers control over all relevant study parameters and enables specific manipulation of the visual, auditory, and physical stimuli via the VR and also due to mechanical perturbation of the treadmill. Thus, one example could include the simulation of a swaying rope bridge. Such methodological advances can only be achieved by a fully integrated and synchronized system, containing the mentioned technical components. Moreover it is possible and planned to implement third-party devices (e.g., eye-tracker, EEG, fNIRS, tES) to study also psychophysiological parameters (e.g., brain activity) during human locomotion. The applicants aim to use this sophisticated instrument for disciplinary and inter-disciplinary research. Namely, to investigate human locomotion within the context of high performance, lifelong development, neurocognition & -motor control, health & well-being, technization & digitalization (see figure 1 in the preamble) under more ecologically valid conditions, to extend and replicate previous results in realistic settings.

明斯特大学运动与运动科学研究所的神经运动行为与运动、运动科学和运动心理学系申请了重大研究仪器，以研究具有实时运动捕捉和在线反馈的交互式虚拟环境中的人类运动。以前的研究在实验室条件下获得了人类运动的开创性知识，例如运动参数或某些患者的年龄相关变化。然而，将实验室结果从外部转移到真实的世界仍然是一个重大的科学挑战。虚拟现实（VR）等技术的进步为提高研究的生态有效性提供了一种创新方法。应用的仪器包括一个基于180°投影的VR环境，带有环绕声系统，以及一个带有集成测力板的多功能跑步机，所有这些都与VR同步。该仪器是由一个高分辨率的运动捕捉系统，使用红外摄像机和无线肌电图的补充。运动捕捉系统和测力板一起构建了与VR和跑步机交互的界面（例如，自定进度模式）。该仪器为申请人提供了一个独特的环境，以研究在现实但仍然标准化和安全的实验条件下人类运动过程中感觉，运动和认知系统之间的复杂相互作用。它提供了对所有相关研究参数的控制，并通过VR以及跑步机的机械扰动实现了对视觉、听觉和物理刺激的特定操作。因此，一个示例可以包括摇摆绳桥的模拟。只有通过一个包含上述技术组成部分的完全一体化和同步的系统，才能实现这种方法上的进步。此外，有可能并计划实施第三方设备（例如，眼跟踪器、EEG、fNIRS、tES）来研究心理生理参数（例如，大脑活动）。申请人的目标是使用这种先进的仪器进行学科和跨学科的研究。也就是说，在更生态有效的条件下，在高性能，终身发展，神经认知和运动控制，健康和福祉，技术化和数字化（见前言中的图1）的背景下研究人类运动，在现实环境中扩展和复制以前的结果。
