Abstract
A cursor control apparatus and a cursor control method thereof are provided. Adjust a position of a cursor on a second axial direction according to a DPI ratio on a first axial direction of display units with different DPI values, so as to make the cursor move smoothly between the display units with different DPI values, in which the first axial direction is perpendicular to the second axial direction, and the display units with different DPI values are arranged along the first axial direction.
Claims18
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 resolution (dots per inch, DPI) ratio of the benchmark display unit to the extended display unit and a second resolution (dots per inch, DPI) ratio of the extended display unit to the benchmark display unit, 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, and selects one of the first DPI ratio and the second DPI ratio, such that the cursor moves back and forth between the first display region and the second display region substantially linearly and in a second axial direction, wherein the first axial direction is perpendicular to the second axial direction.
A cursor control method, 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 method comprising the steps of:
- receiving a displacement value generated from a cursor control unit when moved;
- calculating a first DPI ratio of the benchmark display unit to the extended display unit and a second DPI ratio of the extended display unit to the benchmark display unit;
- determining coordinates of a current position of the cursor;
- controlling the cursor to move in the first axial direction according to the position coordinates and the displacement value;
- and
- selecting one of the first DPI ratio and the second DPI ratio according to a movement direction of the cursor, such that the cursor moves back and forth between the first display region and the second display region substantially linearly and in a second axial direction, wherein the first axial direction is perpendicular to the second axial direction.
