Handwritten input sounds neat. I use and find great value in http://detexify.kirelabs.org/classify.html
Handwritten mathematical expression recognition is general and useful enough that I'd like to see it done outside of SymPy and then imported, this way other projects can also use it. Fedor, can you provide some background on this topic? What other attempts have there been? Are there other systems? What resources have you found? Is this even a feasible problem? What are the hard parts? -Matthew On Wed, Mar 12, 2014 at 11:46 AM, Fedor Morozov <[email protected]> wrote: > Hello, David. > Unfortunately I have no experience with JavaScript yet, but since the main > challenge of the project is the backend part (formula recognition), I can > get enough JavaScript knowledge before the coding phase starts. > I also think that it would be great to develop Sympy Gamma mobile app for > the project and I have some skills for this (Java and Android programming). > Now that the idea is confirmed to be useful I'll take a look into the > issues list, thank you. > > среда, 12 марта 2014 г., 20:38:33 UTC+4 пользователь David Li написал: > >> Hello, >> >> This sounds like a great idea for Gamma.
