I hate typing on mobiles, so wouldn't it be cool if the app could use the camera to look at the text and just tap to highlight/lookup a word?

Voice lookups might also be a good thing.

More recent iPhones can do OCR into (any?) text fields - hold on the text field and select "scan text" or the little box with some horizontal lines in it. It's not perfect for some things (underscores and more unusual punctuation) but it's usually correct

Great idea! Turns out, this already works natively on iPhones already from the camera.
