Startup Idea : Word Grabber

I am not a avid reader and so I usually get stuck in a situation where I am reading an article on the internet or newspaper and because i don't know the meaning of a particular word it takes me a long time to understand the article as I need to do a google search or search for the meaning of the particular word in dictionary. I think there will be millions of such people who face similar problems and so get frustrated while reading. What if we can use our smartphone to click the picture of that word in that article and it quickly shows the meaning and other details of that word. Much Quicker Right! We can build an app for that.
