Claim Text:
1. A cursor control apparatus, adapted to control a cursor to move back and forth between a benchmark display unit and an extended display unit, wherein the benchmark display unit has a first display region, and the extended display unit has a second display region, wherein the first display region and the second display region are adjacent to each other in a first axial direction, the cursor control apparatus comprising: a cursor control unit for generating a displacement value when moved; and a processing unit coupled to the benchmark display unit, the extended display unit, and the cursor control unit, wherein the cursor control unit sends the displacement value to the processing unit, wherein the processing unit calculates a first DPI (dots per inch) ratio of the benchmark display unit to the extended display unit and a second DPI (dots per inch) ratio of the extended display unit to the benchmark display unit, and determines coordinates of a current position of the cursor, controls the cursor to move in the first axial direction according to the position coordinates and the displacement value, wherein when the cursor moves from the first display region to the second display region, the processing unit adjusts a position of the cursor in a second axial direction according to the first DPI ratio, and when the cursor moves from the second display region to the first display region, the processing unit adjusts a position of the cursor in the second axial direction according to the second DPI ratio, such that the cursor moves back and forth between the first display region and the second display region substantially linearly, wherein the first axial direction is perpendicular to the second axial direction.
