Attach events to the input (e.g. keyup, keydown, keypress). There you will set up a setTimeout with a callback. Of course the timeout ID will be stored in a var (e.g. window.type_timeout). The setTimeout callback will do what you want ater those 3 seconds of inactivity.

You can start here. E.g.(using jQuery):

$('input').on('keyup',function(){
    if( window.type_timeout ) clearTimeout( window.type_timeout );
    window.type_timeout = setTimeout( do_stuff , 3000 , this /* extra data */ );
});

function do_stuff( input ){ /* do your stuff */ }
