6.2-1 Separate Input Devices for Displays

When control of the large- and individual-view display devices is performed by separate input devices, their design should support coordinated use.

Additional Information:
Problems that may result from poor coordination of multiple input devices include errors in using the wrong input device, awkward transitions between the input devices, and clutter at the operator's workstation resulting from the input devices (especially if a movable input device such as a mouse is used). The input devices should have compatible methods of operation as described in Guideline 2.3.4-4.
