For our the knolling of the interfaces we looked at the the functions and how they influence the user both physically and mentally. We were intrigued and suprised by how much objects influence us in our daily life.

Just their presence alone can implant something in our head, like concepts of safety, hygiene or rest to name a few, and we associate these objects to them unconsciously.

It's also interesting to see how colors and shapes play a role in that, for example how the color yellow and the arrow is often used to make the user move/behave a certain way.
