If a cursor motion is used to transfer input control between the large- and individual-view display devices, then the movement between the displays should be smooth and contiguous.
Additional Information:
In this approach the desired display device is accessed by moving the cursor into the display space of a particular device. As the cursor crosses from one display device to another it should either (1) maintain continuous horizontal motion for side by side monitors, (2) maintain continuous vertical motion for stacked monitors or (3) should jump between uniquely designated locations on each screen, as described in Guideline 2.3.4-2. One should be able to follow the cursor with a simple movement of the head or eye. A combined motion such as raising and turning one's head should not be required.
