Question

Quizplus · Accepted Answer

The control-display (C-D) ratio is an important concept in ergonomics and human-computer interaction. It defines the relationship between the physical movement of a control device (like a mouse, joystick, or trackball) and the resulting movement on the display screen. A higher C-D ratio means that a small movement of the controller will result in a large movement on the display, which can be useful for tasks requiring fast navigation across the screen. Conversely, a lower C-D ratio means that more physical movement is required to move the cursor or object on the screen, which can allow for more precise control.
