The position of a symbol presented on a visual display unit is selectively controlled by either physical movement information (e.g. mouse movement) or the user's gaze position. Rapid and/or significant change in determined gaze position to a position on the visual display unit followed by the determined gaze position lingering at the position will cause the system to use the user's gaze position to move the symbol else the physical movement information is used. |
