This week we learn the notion of commutation test and how the process of changing one element in a design can affect the entire design and how the meaning of one element can change depending on its co-text. Lacey,N.(1998) states that we should figure out which the main object contribute the most meaning of a image. We discuss the main elements of our interior design are colour and texture. We use and cut foam plastic board to make floor and wall. And then we choose the golden and wood patterns to stick on these boards to make model looks traditional and modern. Also our group member Lynn brings her amazing blue print drawing to make our project more professional !
