의도적으로 <사용성>을 낮추는 방법:

> - Hide critical components: make things invisible.
> - Use unnatural mappings for the execution side of the action cycle, so that the relationship of the controls to the things being controlled is inappropriate or haphazard. (see [Natural mapping](https://wiki.g15e.com/pages/Natural%20mapping.txt))
> - Make the actions physically difficult to do.
> - Require precise timing and physical manipulation.
> - Do not give any feedback.
> - Use unnatural mappings for the evaluation side of the action cycle, so that system state is difficult to interpret. --p206, <The design of everyday things>
