**b.** Perceptual segregation

The perception of the interior needs two visual steps, first to differentiate the separation and second to recognize the shapes of the components (**Figure 3**). The appearance of the interior appears completely after some seconds based on the receptor's ability of perception. The complete interior looks divided by two, but after a while, the full picture shows the unity of this interior.

#### **c.** Perceptual construction

Interiors appear as result of grouping the pieces all together in one scene (**Figure 4**). The whole picture gives the idea, but in perceiving it over time, the main seating and flooring details and patterns come out in the full perception.
