Ease-In/Ease-Out
This term deals with the positioning of an object between keyframes. In most computer software you can adjust the speed at which an object enters or leaves a keyframe. By making an object slow down as it approaches (Ease-In) or slowly speed up as it leaves (Ease-Out) you can smooth out action. For example, when a ball is bouncing it will slowly come to a stop at the top if its climb (Ease-In) and then slowly accelerate as it rushes toward the ground (Ease-Out).
Exaggeration
The idea behind exaggeration is to accent the action. However it should be balanced and not used abitrarily. One should figure out the reason for an action, or even sound effects, character design etc... and how to exaggerate the needed sections. The result will be that the animation will seem more realistic and entertaining.
What I am attempting to do is stop the "Animatronic" look and make everything smoother
