how do I use "track motion" to create organic movement?

Hi - Any help would be greatly appreciated. Here is my dilemma:

I've got footage of an actor walking across the screen. I'd like to have the actor be followed/trailed by an animated, floating heart. I'm trying to use "track motion" to move the heart in sync with the actor's movements but it doesn't feel organic or "flowy" (for lack of a better word). I guess I would prefer that it move in a way similar to a balloon might move if the actor were holding by a string. So that, when the actor begins to move, the heart would start moving after a short delay, and when the actor stops again, the heart might slow down a second or two later.

Is there an Expression that would accomplish this effect?

Thanks!!
 
film a balloon (nice contrasty color to background) track the motion, apply it to a null, parent that null to your heart layer, move it where you want it.

Ah yes, Derrick. Thanks. Great idea. Not sure why I was trying to re-invent the wheel, but I like your idea.
Thanks!
