I found a web application that recognizes handwritten math equations:
http://webdemo.visionobjects.com/equation.html?locale=default
I would like to know if someone knows an app or a tutorial or an open source project that implements this mechanism, because getting it from this webapp is really complex.
Note: I just need the equation drawn in the canvas to be translated in an input text box that's all.
