mation about people, objects, services, and so on. Often, they are invisible and are
used almost subconsciously due to the familiarity everyone has with recognized
conventions, such as on/off switches, play and pause buttons, airports and train
stations, and toilets ( Figure 6.1 )! If you think carefully about icons, you'll find that
you use them more often than you realize.
Since the dawn of man, icons have been used for communication. For example,
cave dwellers painted on their caves to record details of meetings and food. And
the more recent examples of Egyptian hieroglyphics and Chinese symbols most
definitely fall under the moniker of icons.
NOTE: I became interested in icons after serving as editor on fellow English gent
Jon Hicks's marvelous book, The Icon Design Handbook (Five Simple Steps, 2012) .
In fact, this chapter is influenced heavily by Jon's wonderful work. I highly
recommend that everyone purchase his book because it is a real joy to read
and provides more in-depth information than I've assembled in this short account.
