发明名称 Method and system for inputting coordinates using digitizer
摘要 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.
