Math InputPanel and InftyReader both work OK, but not perfect by any means.
I would expect this program to work only on very clean images well focused and within its probably quite limited domain of known notation. That is, excellent demo-ware but probably not ready for prime time. This technology is easy at the 20% level, hard at the 80%, and beyond state of the art at 95%. If all you want to do is read novels to translate into Kindle form, it is close to 100%. But not for math. There used to be a free version of InftyReader, maybe not any more? Camera input (or scanner input) is quite different technically from stylus (or finger) input. Also typeset vs handwritten. My favorite mostly -under-developed technology is SPEECH --i.e. speaking math into your phone or computer. I've done some work on this (search for Math Speak and Write) which someone would be free to pick up and run with. Unfortunately it currently depends on some windows speech SDK. Could be done with some free speech stuff maybe.
