At Starbucks the other day, I noticed that the restroom signs had braille (or what looked like braille) under the man/woman graphics. At other locations, I’ve seen braille-looking dot patterns on various signs, some at arm height and some not.
My question is: How are blind people supposed to find these tiny patches of braille?
Take Starbucks, for example. I can’t imagine anyone walking around with their arms outstretched the whole time feeling for braille… they’d eventually end up groping someone or breaking one of the display ornaments/cups, no?
Or, more generally, how do blind people know where signs are in the first place before they can touch them and feel the braille? The signs I’m talking about are just ordinary plastic signs that do not emit any apparent sound or odor, so I don’t think you’d be able to navigate to them using the other senses.
So how’s it done?
