Semiotics refer to symbols, signification and signs. When thoughts and actions are communicated visually into sings and symbols, we use our unconscious cultural knowledge to create meaning.
Our mind creates meaning or a background into what we are being shown, it how that meaning is conveyed and our ability to interpret cultural messages and conventions. Signs and symbols can mean different things in different cultural settings and contexts. For example a thumbs up as a general term can mean ‘okay’ whereas if it were seen at the side of the road it would mean they want to hitch a ride.

Semiotics are important for my assignment as I am trying to bring meaning to an image I am creating and relate it to an article. In my image I will be using a few distinctive symbols such as the tree to signify nature and a hand to signify the human touch.
