Abstract

In a computer controlled user interactive display, a system is provided for controlling cursor movement on the display screen involving a user activated cursor control device connected to said computer movable in the four orthogonal directions. The system has conventional means for converting the user activated orthogonal movements into cursor movements in said orthogonal directions on said display screen and user interactive means for scaling said cursor movements in each of said four orthogonal directions relative to the corresponding movements in said cursor control device. The invention is particularly directed to such cursor movement rate scaling in respective windows.

Claims

1. In a computer controlled user interactive display, a system for controlling cursor movement on the display screen comprising:

a user activated cursor control device connected to said computer movable in the four orthogonal directions,

means in said computer for converting said user activated orthogonal movements into cursor movements in said four orthogonal directions on said display screen,

user interactive means in said computer for scaling said cursor movements in each of said four orthogonal directions relative to the corresponding movements in said cursor control device, and

means in said computer for defining regions on said display screen wherein cursor movements in one orthogonal direction have different scaling values from the scaling values of movements in the same one orthogonal direction in regions adjacent to said defined regions.

2. The computer controlled user interactive display of claim 1 further including:

means in said computer defining a default scaling value for said cursor movements in each of said four orthogonal directions, and

user interactive means for changing said default scaling values for said cursor movements in each of said four orthogonal directions.

3. The computer controlled user interactive display of claim 1 wherein said defined regions and said adjacent regions are defined from each other by at least one orthogonal axis.

4. The computer controlled user interactive display of claim 2 further including means for changing the image of the cursor when said cursor has a movement scaling value other than a default value.

5. The computer controlled user interactive display of claim 2 further including at least one window wherein said cursor movement in at least one of said orthogonal directions is scaled different from said cursor movement in said same orthogonal direction in a region of said screen outside of said window.

6. The computer controlled interactive display of claim 5 wherein said region is within another window on said screen.

7. In a computer controlled user interactive display with a user activated cursor control device connected to said computer movable in the four orthogonal directions, a method for controlling cursor movement on the display screen comprising:

converting said user activated orthogonal movements into cursor movements in said four orthogonal directions on said display screen,

scaling said cursor movements in each of said four orthogonal directions relative to the corresponding movements in said cursor control device, and

defining regions on said display screen wherein cursor movements in one orthogonal direction have different scaling values from the scaling values of movements in the same one orthogonal direction in regions adjacent to said defined regions.

8. The method of claim 7 further including the steps of:

defining a default scaling value for said cursor movements in each of said four orthogonal directions, and

user interactively changing said default scaling values for said cursor movements in each of said four orthogonal directions.

9. The method of claim 8 wherein said default values in at least one of said orthogonal directions is changed to increase the scaling values.

10. The method of claim 7 wherein said defined regions and said adjacent regions are defined from each other by at least one orthogonal axis.

11. The method of claim 8 further including the step of changing the image of the cursor when a cursor movement scaling value is changed to a value other than a default value.

12. The method of claim 8 wherein said display further includes at least one window and wherein said cursor movement in at least one of said orthogonal directions is scaled different from said cursor movement in said same orthogonal direction in a region of said screen outside of said window.

13. A computer program having data structures included on a computer readable medium for controlling cursor movement on a computer controlled display with a user interactive cursor control device connected to said computer and movable in the four orthogonal directions comprising:

means for converting said user activated orthogonal movements into cursor movements in said four orthogonal directions on said display screen,

user interactive means for scaling said cursor movements in each of said four orthogonal directions relative to the corresponding movements in said cursor control device, and

means for defining regions on said display screen wherein cursor movements in one orthogonal direction have different scaling values from the scaling values of movements in the same one orthogonal direction in regions adjacent to said defined regions.

14. The computer program according to claim 13 further including:

means defining a default scaling value for said cursor movements in each of said four orthogonal directions, and

user interactive means for changing said default scaling values for said cursor movements in each of said four orthogonal directions.
