The Activity of viewing –
Looking at the drawing of the duck/ rabbit shows that the eye can more between interpretations very quickly, but more importantly it shows that the way we see is so dependant on how we interpret that we rarely take the time to consider the process taking place. Therefore we must consider that a vast amount of the world is possibly not material and so must be included by imagination from the signals we are interpreting.
Desicribe how objects can be ambigous:
Mobile phone – a rectangular shape with smooth edges could be described as the starting point of most smart phone designs since the growth in popularity of the Iphone.
Cutlery – A line with a oval at the top might be seen as a spoon, next to a straight line for the knife and then a third line with three smaller lines going upward next to each other above this line could be interpreted as a fork. Therefore we are used to interpreting these simple shapes and may no longer need the metallic or plastic items present for them to come to mind when seeing a drawing as described above.
