Method and system for inputting coordinates using digitizer
First Claim
1. A system for inputting coordinates using a digitizer, comprising:
- a display device provided with a display which has a first area;
a digitizer coupled to said display device and provided with a pointing region which has a second area smaller than the first area;
a pointing device coupled to said digitizer for pointing an arbitrary dot position on the pointing region of said digitizer; and
control means coupled to said display device and said digitizer for controlling display information on the display of said display device so that a pointing area which is displayed on the display is smaller than the first area and corresponds to the pointing region of said digitizer and a dot pointed by said pointing device on the pointing region of said digitizer is displayed within the pointing area, said pointing region of the digitizer including a number of dots which is greater than or equal to a number of dots included in the pointing area of the display,said control means including means for moving the pointing area on the display in an arbitrary direction depending on a specific part of the pointing region which is pointed by said pointing device.

Abstract
A system for inputting coordinates using a digitizer includes a display device provided with a display which has a first area, a digitizer provided with a pointing region which has a second area smaller than the first area, where the pointing region includes a number of dots which is greater than or equal to a number of dots included in the first area, a pointing device for pointing an arbitrary dot position on the pointing region of the digitizer, and a controller for controlling display information on the display of the display device so that a pointing area displayed on the display corresponds to the pointing region of the digitizer and a dot pointed by the pointing device on the pointing region of the digitizer is displayed within the pointing area. The controller moves the pointing area on the display in an arbitrary direction depending on a specific part of the pointing region which is pointed by the pointing device.

10. A method of inputting coordinates using a digitizer which is coupled to a display device and a pointing device, said display device being provided with a display which has a first area, said digitizer being provided with a pointing region which has a second area smaller than the first area, said pointing device pointing an arbitrary dot position on the pointing region of said digitizer, said method comprising the steps of:
-
displaying on the display a pointing area which is smaller than the first area and corresponds to the pointing region of the digitizer, said pointing region of the digitizer including a number of dots which is greater than or equal to a number of dots included in said pointing area of the display; moving the pointing area on the display in an arbitrary direction depending on a specific part of the pointing region which is pointed by the pointing device; and displaying within the pointing area of the display a dot which is pointed by the pointing device on the pointing region of the digitizer. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
