By Michel BaudinThis photo, from a Cadillac car I rented, shows one of the most bewildering sets of controls that I have seen. I never could figure out what some of these controls did, even after trying them. It appears that these were intended to imitate European designs, that rely on pictograms to communicate with drivers from countries with different languages.
Symbols do have an advantage over words in that they take less space resulting in a "cleaner" design. Using symbols that are familiar to most people is fine. Familiar symbols are typically standard symbols in widespread use.
Using unfamiliar symbols is problematic when people can not understand
the symbols without additional information, such as having to read a manual.
This is especially problematic in situations, such as renting a car,
where people may not have a manual or may not have the time or inclination to read one.
In these situtions, symbols could be replaced by or accompanied by a word,
in the common language, describing the control.
