The world space defined by a traditional virtual reality application is generally regarded as separate from the real-world space in which users actually exist. In this paper, we present a method that enables such detached spaces to connect in an integrated space. In particular, we show that by using a specially manufactured calibration board and three consumer-grade position tracking devices, a reference coordinate system can easily be set up in the physical space, whose geometric relationship with the virtual reality space is estimated with high numerical accuracy and stability. Then, we demonstrate that, combined with traditional computer vision techniques for marker tracking, the presented technique allows colocated users from virtual, augmented, and mixed realities to cooperate with each other while making effective use of technologies from other realities.

传统虚拟现实应用程序定义的世界空间通常被认为与用户实际存在的现实世界空间是分离的。在本文中，我们提出了一种方法，使这种分离的空间能够连接到一个集成空间中。特别是，我们展示了通过使用特制的校准板和三个消费级位置跟踪设备，可以在物理空间中轻松建立参考坐标系，其与虚拟现实空间的几何关系以高数值精度估计和稳定性。然后，我们证明，结合用于标记跟踪的传统计算机视觉技术，所提出的技术允许来自虚拟、增强、
