A trackball is a pointing device that consists of a spherical ball that rotates on a fixed base. By moving the ball with your fingers or palm, you can steer the cursor on a computer display. This device is particularly useful in situations where there is limited desk space or where precise pointing is required. Therefore, the trackball is the best choice for this question.
