3 Interface Examples

As part of the homework assignment we were asked to document three interfaces we encounter around Copenhagen. The first image (see below) depicts the speakerphone installed in our apartment. Instead of pushing a single button at the apartment door, users are expected to perform the following steps:

  1. Go to the living room and look behind the door
  2. Pick up the phone
  3. Dial any number on the keypad
  4. Dial the number written just above the keypad (#569)


After getting back to the apartment I was challenged by an electrical outlet (see below). While the idea of being able to switch individual outlets on and off is pretty nice – it wasn’t so obvious which of the two switches were turned on. Had to check the «charging…» indicator on my phone to confirm. The switches seem pretty standard around Copenhagen so far, so I assume there must be a convention in place.


Finally, the next image shows the whisk used to prepare the delicious pancake batter we enjoyed this morning. Its an extremely obvious interface that just about anybody can use.
