is the space where interactions between humans and machines occur. The goal of this interaction is to
allow effective operation and control of the machine from the human end, whilst the machine simultaneously
feeds back information that aids the operators decision making process.
Generally, the goal of human-machine interaction engineering is to produce a user interface which makes it easy
(self explanatory), efficient, and enjoyable (user friendly) to operate a machine in the way which produces the desired result.
This generally means that the operator needs to provide minimal input to achieve the desired output, and also that
the machine minimizes undesired outputs to the human."
