Best practice: consider chartplotter (MFD) context

Contextual placement of touchscreen displays may affect usability. For example:

Locating a display where it is likely to be knocked or bumped could result in unintentional switching actions.
A display that is grouped with other controls (for example, an array of physical switches) will form an automatic association between the grouped controls for users.

When locating touchscreen displays:

Consider the context of the display with respect to other user controls, and with the user’s position while operating the display.
Where space is limited and accidental touchscreen presses may be hard to avoid, consider safeguarding the touchscreen with appropriately positioned physical barriers.
Consider the context of the display with respect to the systems or equipment under control. In some cases (for example, moving equipment), maintaining line-of-sight between the user operating the chartplotter (MFD) and the controlled equipment is important.
