The Samsung Note3 (and presumably later versions) come with S Note (which I just found is also available for windows[1]) -- and does a decent job of translating hand-drawn equations (eg sum over x=0 to infinity for 1/x). Not sure about the pc version (yet). Might be worth looking at for those that have a windows tablet/device with stylus input.

More than symbol names, I can never remember details about package options. To set uniform margins with the geometry package, is the keyword "margin" or "margins"? If I want to scale tgschola, is the keyword "scale" or "scaled"? Why don't package writers anticipate this?
Similarly, depending on the font, the command to get an upright lowercase alpha is either \upalpha, \alphaup, \otheralpha, or something else. Why?

Recognizes full equations and even sends it to wolfram alpha to compute result
