I have a web application contains javascript signature pad popup, this web page is working perfectly when I open it from the tablet screen and the user can sign using the tablet pin.

What I need to do is when I open the page from PC, I need to take the customer signature using tablet. So I tried to share the PC screen using mirorring applications but it didn't catch the pointer/mouse position correctly on tablet.

I'm using the javascript pad, because it's more smooth than the electronec devices.

Is there any other way to take the customer signature using the Tablet when I open the page from PC ?
