Inspired by the posts about people over fifty in the US who struggle with financial terminology.
I started thinking about something that is more universally understood - symbols!
The best example I could think of the use of symbols to get information are the new feedback machines at airports.
After going through airport security in the UK, Spain and Vienna I have encountered one of these freestanding machines. They have four faces on them - - to denote different emotional states. You press down on the symbol that reflects your experience of airport security.
It is quick, simple and is universally understood.
