The way real world things work is represented in our mind as a so-called mental model. The whole world with all its properties can't get in our mind. It would be too much data and what we perceive is heavily filtered anyway by our senses. | The way real world things work is represented in our mind as a so-called mental model.

If you are the engineer who build these systems it is totally clear for you how they work. As well it will be often the case that your mental model is differs from the one the users have. This itself is nothing to worry about and it happens all the time. But even if you are very clever you just can spot the problems that it can cause if you test your ideas with your users and see if they act like you intended. | If you are the engineer who build these systems it is totally clear for you how they work.
