WebXR API Emulator 作成者: Mozilla Mixed Reality

WebXR Emulator extension enables users and developers to run and test WebXR content in desktop browsers without using a real XR device.
The extension will emulate the WebXR API on browsers that don’t support it yet and also provide a list of XR devices with their controllers to emulate.
