The present remote collaboration system was implemented based on immersive web1 technologies. In our previous studies, we developed the WXR system, which allows users to have the same experience regardless of the XR devices used if the device’s browsers support web standards (Lee & Yoo, 2021). The server program was implemented with Node.js and MariaDB and ran on a PC (Intel Xeon E5-2699 v4 2.2 GHz CPU, 64 GB DDR4 RAM) under the Microsoft Windows 10 operating system. The client program was implemented using A-Frame (v1.2.0) (Marcos et al., 2023), an open-source web framework for creating VR scenes. The client program runs in all browsers supporting web standards, and users can connect any device to the browsers using the WebXR Device API (World Wide Web Consortium, 2022). Because of the absence of an object tracking function for the WebXR Device API, we additionally implemented a custom web browser for iOS using the WebKit and ARKit frameworks.
