Abstract
Abstract A graphical universe that is larger than a display screen is displayed on a screen using a panning operation. To view portions of the graphical universe, a cursor positioned on the display screen using an input device is utilized to fix a reference location for the panning operation. By moving the cursor on the display screen, a line between the cursor and the reference location is provided. The direction of the line indicates direction of the panning operation, while the length of the line determines speed of the panning operation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
157 words
A method for panning a graphical space across a display screen having a viewing area, comprising the steps of: displaying a portion of said graphical space on said display screen which is smaller than said graphical space; positioning a cursor at a selected position on said display screen and activating an input device that controls said cursor such that a reference location is fixed at said selected position, said selected position being any location within the viewing area of said display screen; moving said cursor from said reference location on said display screen in a direction in which another portion of said graphical space which is to be displayed is located, such that a line between said cursor and said reference location is provided on said display screen to indicate said direction; and sliding said graphical space across said display screen in said direction until the desired portion of said graphical space is on said display screen.
Claim 2
Independent Claim
157 words
A method for panning a graphical space across a display screen having a viewing area, comprising the steps of: displaying a portion of said graphical space on said display screen which is smaller than said graphical space; positioning a cursor at a selected position on said display screen and activating an input device that controls said cursor such that a reference location is fixed at said selected position, said selected position being any location within the viewing area of said display screen; moving said cursor from said reference location on said display screen in a direction in which another portion of said graphical space which is to be displayed is located, such that a line between said cursor and said reference location is provided on said display screen to indicate said direction; and sliding said graphical space across said display screen in said direction until the desired portion of said graphical space is on said display screen.
Claim 3
Independent Claim
176 words
A method for panning a graphical space across a display screen having a viewing area, comprising the steps of: displaying a portion of said graphical space on said display screen which is smaller than said graphical space; positioning a cursor at a selected position on said display screen such that a reference location is fixed at said selected position, said selected position being any location within the viewing area of said display screen; moving said cursor from said reference location on said display screen in a direction in which another portion of said graphical space which is to be displayed is located, such that a line between said cursor and said reference location is provided on said display screen to indicate said direction; and sliding said graphical space across said display screen in said direction until the desired portion of said graphical space is on said display screen and varying a display speed of sliding said graphical space across said display screen in the direction of said line in response to a length of said line.
Claim 4
Independent Claim
176 words
A method for panning a graphical space across a display screen having a viewing area, comprising the steps of: displaying a portion of said graphical space on said display screen which is smaller than said graphical space; positioning a cursor at a selected position on said display screen such that a reference location is fixed at said selected position, said selected position being any location within the viewing area of said display screen; moving said cursor from said reference location on said display screen in a direction in which another portion of said graphical space which is to be displayed is located, such that a line between said cursor and said reference location is provided on said display screen to indicate said direction; and sliding said graphical space across said display screen in said direction until the desired portion of said graphical space is on said display screen and varying a display speed of sliding said graphical space across said display screen in the direction of said line in response to a length of said line.
Claim 5
Dependent Claim
18 words
The method according to claim 2, wherein the length of said line is indicative of said display speed.
Claim 6
Dependent Claim
43 words
The method according to claim 3, wherein said display speed of sliding said graphical space increases if the length of said line is increased, and said display speed of sliding said graphical space is reduced if the length of said line is decreased.
Claim 7
Independent Claim
194 words
An apparatus for panning a graphical space across a display screen, comprising: a display screen having a viewing area for displaying a portion of said graphical space, said display screen being smaller than said graphical space; an input device for positioning a cursor at a selected position on said display screen such that a reference location is fixed at said selected position, said selected position being any location within the viewing area of said display screen; said input device being operative to move said cursor from said reference location on said display screen in a direction in which another portion of said graphical space which is to be displayed is located, such that a line between said cursor and said reference location is provided on said display screen to indicate said direction; sliding means for sliding said graphical space across said display screen in said direction until the desired portion of said graphical space is displayed on said display screen; and said input device being operative to vary a display speed of sliding said graphical space across said display screen in the direction of said line in response to a length of said line.
Claim 8
Independent Claim
194 words
An apparatus for panning a graphical space across a display screen, comprising: a display screen having a viewing area for displaying a portion of said graphical space, said display screen being smaller than said graphical space; an input device for positioning a cursor at a selected position on said display screen such that a reference location is fixed at said selected position, said selected position being any location within the viewing area of said display screen; said input device being operative to move said cursor from said reference location on said display screen in a direction in which another portion of said graphical space which is to be displayed is located, such that a line between said cursor and said reference location is provided on said display screen to indicate said direction; sliding means for sliding said graphical space across said display screen in said direction until the desired portion of said graphical space is displayed on said display screen; and said input device being operative to vary a display speed of sliding said graphical space across said display screen in the direction of said line in response to a length of said line.
