Attempting to nest WebGazer into a Win32 program to help people with hand defects, encountered some issues

Thank you for the great idea and implementation of this project, which can help many people with hand disabilities have free eye tracking solutions to use.

I am a software developer in the Windows field,
I accidentally found this library, and when I browsed it again, I found that after some modifications, it can help some people with hand disabilities use free eye tracking to operate their computers. However, in the actual testing environment, I have found some problems and would like to ask if there are any solutions here:

1. Can the camera loaded with HTML be shared across pages? Assuming multiple pages are not in the same location, can the same camera image data be transferred to different pages, and the page returns different coordinate data based on its own size and location.
2. In the actual testing of Edge browser, I found that if I switch Edge to a non focus window, it will be particularly slow after a period of time.
3. After calibration, if the eyes remain stationary, the returned coordinate information will also differ significantly.
