I want to detect whether or not a user has been active in the past 10 minutes using a batch file or some background process

Question

I've never worked with batch files before, but the idea behind this is that I want to simply run a program after I've been inactive for a certain period of time.
It doesn't matter which program, I just want it to run concurrently with my screensaver for some lighting effects with my keyboard.
I suppose another solution would be to detect whether the screensaver is running or not and start on that condition as well, I just have no idea where to begin with this one, but am willing to learn.

This powershell gets all users last long on time. Change the time variable, should work.

Import-Module ActiveDirectory

function Get-ADUsersLastLogon()
{
  $dcs = Get-ADDomainController -Filter {Name -like "*"}
  $users = Get-ADUser -Filter *
  $time = 0
  $exportFilePath = "c:\lastLogon.csv"
  $columns = "name,username,datetime"

  Out-File -filepath $exportFilePath -force -InputObject $columns

  foreach($user in $users)
  {
    foreach($dc in $dcs)
    { 
      $hostname = $dc.HostName
      $currentUser = Get-ADUser $user.SamAccountName | Get-ADObject -Server $hostname -Properties     lastLogon

      if($currentUser.LastLogon -gt $time) 
      {
        $time = $currentUser.LastLogon
      }
    }

    $dt = [DateTime]::FromFileTime($time)
    $row = $user.Name+","+$user.SamAccountName+","+$dt

    Out-File -filepath $exportFilePath -append -noclobber -InputObject $row

    $time = 0
  }
}

Get-ADUsersLastLogon

Just schedule a task in Task Scheduler to run only if user not used computer in last 10 mins.
