Abstract

A computer system is disclosed and includes a user input device that provides a user input signal indicative of user inputs. A controller is coupled to the user input device and a display device. The controller is configured to receive the user input signal, display a cursor image on the display device based on the user input signal, and display an ancillary image based on at least one characteristic of the cursor image. The controller is also configured to display the ancillary image to move based on movement of the cursor image on the display device.
