Create a timer in your javascript code and call a URL on your server to log activity.

Fortunately it is impossible...
1. To get any info from the end user he must browse your site...
2. Even one browse your site ad you add a JavaScript function to ping the server with user info it will means nothing, it is still possible that user left the building 10 hours ago...

There is not proven method to check user's presence without actually asking...
