Semiotics, meaning the use of communication through signs and symbols, is used for many different things. A good example of this would be traffic signs. There are often symbols for pedestrians crossings made with silhouettes or simple stick figures. The purpose is usually to warn people of what to expect, and provide helpful information. By this I mean that signs will usually have written directions, or symbols of arrows to show a certain way. These images show examples of the written communication.
The one near the docks has examples of visual communication. These symbols include a fish silhouette for "no fishing" and two people in dangerous situations. These are warning signs for people not to swim in the docks or stand too close to the edge. Semiotics can also include labels on packaging and many different logos. It is also a great way to advertise, using posters, flyers, cd and dvd covers. It can also be used as a way to create very eye catching signs using just a font, or even a single Illustration.
