Inspired by Google's handwriting input, I decided to make my own app with handwriting input in MIT AI2.
For writing, I used a canvas, that will capture the handwritten text as an image and pass that to an OCR system. But, I didn't find any working OCR extension/API.
I looked up a the FAQ Section on OCR.
But I couldn't make it work.
The extension seem to do nothing (atleast in MIT AI2) and I am not very familiar with Web APIs. The last option seemed the most promising (coz it worked offline) but wasn't working for me as well.
So if anyone could make it work, please leave the .aia file of it. I'd be hugely grateful.
UPDATE
The App is now complete. See here.
