It doesn't and can't do the "bus sign" thing. It tells you how much off axcis
your focus is, and does a lot of prerecognition image processing.

Greetings All.
I wonder how well the talking camera compensates for the picture being out
of whack as I am sure the camera is not aimed directly where it should be
most of the time.
As to the delay, if I was killing time reading a print magazine or something
like that, I don't think that long a wait would be that big a deal.
From an orientation and mobility perspective, I could see that the camera
could be useful (help might be needed) in capturing the image through
pictures of the various signs of what is on the block and between which
establishments, for instance, the bus stop is located. I am guessing that
that would not be a one-shot deal.
