This is amazing, and it has truly revolutionary implications for learners of scripts like Chinese, which are still truly indecipherable to learners when embedded in images. I was really happy to see that this extension supports both simplified and traditional Chinese. I tried it out, and while it shows promise there, it definitely still needs a lot of work.
I posted a review on my blog here: http://www.sinosplice.com/life/archives/2014/04/24/can-proje...
OP, I'd be happy to work with you on improving the recognition of Chinese text. Just get in touch with me through my blog (linked to above).
