I studied the VR demo of industrial robot recently. When I entered VR in windows chrome browser with add on webXR API emulator, this is no reticle pointer displayed so that I could not gaze the button to start animantion. Why?
In your manual, there is reticle pointer displayed.
It appears that WebXR Device emulator does not send “connected” event for gaze controller. That’s why you don’t see the reticle. On real devices the gaze works fine. You might want to report this issue to WebXR emulator developers.
