But what about those of us whose normal face is smiling, i.e. happy people?

I think someone asked this earlier this summer. There are several patents covering this. Look them up and they will tell you the whole algorithm. That's what they have to do in order for their patent to be granted.
You can also try by looking around here: http://iris.usc.edu/Vision-Notes/bibliography/contentspeople.html#Face%20Recognition,%20Detection,%20Tracking,%20Gesture%20Recognition,%20Fingerprints,%20Biometrics It has sections like:
21.3.6 Facial Expressions and Emotion Analysis and Description
21.3.6.1 Face Expression Recognition and Analysis, Facial Expression Analysis, Facial Expressions
21.3.6.1.1 Three-Dimensional Face Expression Recognition and Analysis
21.3.6.1.2 Face Action Units for Expressions and Motion Analysis
21.3.6.1.3 Face Expression Recognition from a Single Image
21.3.6.2 Emotion Recognition from Face Images
21.3.6.2.1 Emotion Recognition, from Other Than Faces
21.3.6.3 Facial Expressions, Overviews, Surveys, Data

That site had just the papers. I thought you were going to program up some algorithm on your own, that is assuming you were just going to implement an existing algorithm rather than invent your own. If you simply want to run someone else's code, then see if there is one in the File Exchange that you can run. Or else hire someone to write some for you, or else see if you can buy some code from someone who is selling such code.
