Modern virtual reality (VR) devices record six-degree-of-freedom kinematic data with high spatial and temporal resolution and display high-resolution stereoscopic three-dimensional graphics. These capabilities make VR a powerful tool for many types of behavioural research, including studies of sensorimotor, perceptual and cognitive functions. Here we introduce Ouvrai, an open-source solution that facilitates the design and execution of remote VR studies, capitalizing on the surge in VR headset ownership. This tool allows researchers to develop sophisticated experiments using cutting-edge web technologies such as WebXR to enable browser-based VR, without compromising on experimental design. Ouvrai’s features include easy installation, intuitive JavaScript templates, a component library managing front- and backend processes and a streamlined workflow. It integrates with Firebase, Prolific and Amazon Mechanical Turk and provides data processing utilities for analysis. Unlike other tools, Ouvrai remains free, with researchers managing their web hosting and cloud database via personal Firebase accounts. Ouvrai is not limited to VR studies; researchers can also develop and run desktop or touchscreen studies using the same streamlined workflow. Through three distinct motor learning experiments, we confirm Ouvrai’s efficiency and viability for conducting remote VR studies.

现代虚拟现实（VR）设备以高空间和时间分辨率记录六自由度运动学数据，并显示高分辨率立体三维图形。这些功能使 VR 成为多种行为研究的强大工具，包括感觉运动、知觉和认知功能的研究。在这里，我们介绍 Ouvrai，这是一种开源解决方案，可利用 VR 耳机拥有量激增的机会，促进远程 VR 研究的设计和执行。该工具允许研究人员使用 WebXR 等尖端网络技术开发复杂的实验，以实现基于浏览器的 VR，而不会影响实验设计。 Ouvrai 的功能包括易于安装、直观的 JavaScript 模板、管理前端和后端流程的组件库以及简化的工作流程。它与 Firebase、Prolific 和 Amazon Mechanical Turk 集成，并提供用于分析的数据处理实用程序。与其他工具不同，Ouvrai 仍然免费，研究人员通过个人 Firebase 帐户管理他们的网络托管和云数据库。 Ouvrai 并不局限于 VR 研究；研究人员还可以使用相同的简化工作流程来开发和运行桌面或触摸屏研究。通过三个不同的运动学习实验，我们确认了 Ouvrai 进行远程 VR 研究的效率和可行性。
