$( "#container" ).mouseover(function() {
 $( "#target" ).mousemove(function( event ) { 
  var x = event.pageX;
  var y = event.pageY;
  /* here you add or subctract depens on compagin on lastX and lastY */
  /* at the end */
  var lastX = event.pageX;
  var lastY = event.pageY;
});

You are probably searching for the .mousemove() function of jQuery.

Just make sure you apply it to the correct object.
