I want to create a web app(for practicing my skills) that will help in conducting online exams. So I want to ask that is there any way to find out the following things---
- Is there another page opened in the chrome (if yes then which)
- Is there is another application running in the background (if yes then which)
- Is user switching between tabs/applications/desktops etc.
Basically, I just want to create an app that just keeps track of users' activity when the user is giving an exam. And if you have any of the solutions to the above problems then please tell.
