You learn how to use Win32::API

This uses win32::API::Prototype which you may not be able to obtain, but shoudl be readily adaptable to Win32::API. It loops, calling the api and printing the return. Move the mouse or touch a key to see the output change. 

#! perl -slw
use strict;
use Win32::API::Prototype;

ApiLink( 'user32.dll', 'bool GetLastInputInfo( pvoid p )' ) or die $^E
+;

my $info = pack 'VV', 8, 0;

while( sleep 1 ) {
    GetLastInputInfo( $info ) or die $^E;
    printf "Last input was at: %u\n", unpack 'x[V] V', $info;
}
