*2.2.2 Interactions of the physical environment*

Ergonomics deals with solving physical problems in the interface schedule and arrangement and takes into account the design of work environment as well. Where will the system be used? Who will use it? Will people sit, stand, or move around? Again, this will depend on the domain in a great extent, and it will be critical when it comes to specific controls and operational settings. However, the physical environment in which the system is used can affect the health and safety of its users. This should be taken into account in any design [2].
