Google's Project Glass: I Want to Know

Of the many questions prompted by this intriguing video, one pops out and its possible answer excits me.  

I would like to know what would happen if he opened the book he pulled off the bookstore shelf and started reading it.  Could he use zoom and other camera features to adjust for visual impairment?  

In other words would I, with my advanced Retinitus Pigmentosa be able once again to pull regular print books off shelves at home, at the library and at bookstores and read them without a magnifying glass?  

If the answer is 'Yes' then I'm uber excited and only wonder if Google's future will get here in time for me.
