What handwriting APIs can help me with this?

问题

I want to create an application that recognizes handwriting on the screen. I don't need it to recognize insanely difficult words; just simple stuff like "A" "BC" "Z" (maybe some shapes, but could be without this). How do people usually go about this? Are there any famous handwriting recognitions that i can try?

回答1:

If you want to recognize single letters and shapes alike I would suggest using GestureOverlayView.

Read about it here:

It is said to be good for casting HarryPotter-like spells too.
