- Icon – An Icon sign is a sign that resembles something, such as photographs of people. An icon can also be illustrative or diagrammatic, for example a ‘no-smoking’ sign.
Index – An Index signs is a sign where there is a direct link between the sign and the object. The majority of traffic signs are Index signs as they represent information which relates to a location (eg, a ‘slippery road surface’ sign placed on a road which is prone to flooding)
Symbols – A symbol has no logical meaning between it and the object. Unfortunately the web is littered with bad examples of this type of sign, but there are good one’s – a homepage icon which is a house for example. Other off screen symbols which may help explain the difference are flags. Flags are symbols which represent countries or organisations. Again, the crossover to design and branding is very evident in these signs.
This is very interesting for my piece and will help to cover this base with my front cover and double page spread, This could help me to work out how piece will communicate to my audience.
