What is the best way to implement handwritten character recognition in the iPhone?

I'm thinking

First of all, take a picture of the handwritten character.

Second, recognizing the image of the handwritten character, and then outputting the text.

You can use the neural network because the neural network is good in classification but the answer depends on the possibility .. But if you can identify a certain logic in your characters, then you can use fuzzy logic because then the answer will be more accurate than the neural network!
