Is the term "blind spot" peculiar to the English language, or is it likely to be well understood worldwide, even by people who don't have English as their first language?
Some background
I'm currently searching for a term I can use in some software I'm developing. The feature in question allows the user to draw rectangles over an image to denote areas they'd like to ignore in a later analysis of the image. I need the user to be able to create and delete as many of these areas as they like.
Currently, the areas are called "exclusion areas", but that causes problems when you've got a button labelled "Remove exclusion area". We've seen people being tripped up by the double negative.
One thought was to rename the "exclusion areas" to "blind spots". However, do you think this will cause more problems for non-native English speakers?
