I am reading Norman's book, The design of everyday things where I came upto the natural mapping part. There, he defined 3 kinds of natural mapping.
1- Spatial 2- Cultural 3- Perceptual
Now, In spatial, he says,
a control can be used to move the object up and down.
And In perceptual, he gives example of
car seat controls to move the car seat. Now I am confused what is the actual difference between these two? Isn't moving the object up and down or moving the seat with controls are same. I know, I am missing something, so if anyone know, please clear me about this problem and help me to understand it.
