1. An information processing apparatus comprising:
- a display device for displaying images, the display device having a display area;
a tablet input device coupled to said display device with a first inner pointing area surrounded by a second outer pointing area;
a pointing device coupled to said tablet input device for selecting a user-directed position through either said first inner pointing area or said second outer pointing area;
a display controller, coupled to said display device, that controls display information on said display device so that the first inner pointing area maps into a central area of said display area on said display device and said second outer pointing area maps into an outer display boundary of said display area on said display device.

Abstract
An improved method and apparatus in pen-based computer systems using a tablet input device to select the outer boundary area of a graphics display through use of a virtual cursory boundary is disclosed. The tablet input device has a first inner active area surrounded by a second outer active boundary. An operator selectively moving a pointing device in the first inner active area of the tablet input device causes a cursor to move correspondingly on the graphics display image. When the operator selectively moves the pointing device in the second outer active area, the digitizing table causes the cursor to move to a corresponding graphics display boundary position.

4. An information processing apparatus comprising:
-
a display device that displays images within a display area; a tablet input device coupled to said display device with a first inner rectangular pointing area surrounded by a second outer rectangular pointing area having four sides, each of said four sides of said rectangular pointing area intersect to form corner pointing areas; a pointing device coupled to said tablet input device for selecting a user-directed position among said first inner pointing area, said second outer pointing area and said corner pointing areas; a display controller, coupled to said display device for controlling display information on said display device so that the first inner pointing area maps into a central area of said display area, said second outer pointing area maps into an outer display boundary of said display area, and said corner pointing areas map into corresponding corner display boundaries of said display area. - View Dependent Claims (5, 6)

7. A computer program product operable on an information processing apparatus having a display device for displaying images, said display device having a display area, a tablet input device coupled to said display device with a first inner pointing area surrounded by a second outer pointing area, a pointing device coupled to said tablet input device for selecting a user-directed position through either said first inner pointing area or said second outer pointing area, said computer program product comprising:
-
a computer readable medium; computer usable code means, stored in said computer readable medium and executable on said information processing apparatus, for controlling display information on said display device so that said first inner pointing area maps into a central part of said display area and said second outer pointing area maps into an outer display boundary of said display area. - View Dependent Claims (8, 9, 10)
