Here is an example of how we can mess up the interaction with things: this is the ‘key’ of an automatic coffee machine inside its seat.
In the red circle you can see a small tooth used to fix the key to the seat: you usually need two or three attempts before fitting it properly. Plus you can note how (unnecessarily) long the key is: it really bothers you.
The beauty is that this fancy position of the key (standing up) and seating is due to the fact that a SMALL chip has to be next to the reader.
What’s also great is that if you have something hanging from the little half ring in the lower part of the pictures, it covers completely the keyboard where you have to digit the ID of the coffee you want to drink.
It seems like someone had to couple, in a hurry, two distinct designs obtaining a kind of monster #fail
