Abstract

A method and structure for positioning the cursor on a computer which uses a touch pad for cursor control wherein a cursor jumps from one point to another point on the screen without being in between, and wherein a cursor is displayed and a touchpad is connected to the screen, comprising the steps of: associating a coordinate system on the touchpad with a coordinate system on said screen to generate locations on the screen corresponding to given locations on the touchpad; causing the setting of time and pressure on the touchpad for a valid response; causing the determination of an average point with reference to a finger on the touchpad and, thus, a point on the screen for movement of the cursor to the point responsive to the set pressure and time on a given location on the touchpad.

Claims

1. A method of causing a mouse cursor in a computer system to jump from one point on a screen to another point on said screen, and wherein a mouse cursor is displayed on said screen, and a touchpad is operatively connected to said screen, comprising the steps of:

associating a coordinate system on said touchpad with a coordinate system on said screen to generate locations on said screen corresponding to given locations on said touchpad;

setting of pressure for a valid response from said touchpad to said screen at each coordinate location on the touchpad;

setting of the time for a valid response from said touchpad to said screen; and

determining a point with reference to a finger on said touchpad and, thus, an associated point on said screen for the movement of the mouse cursor to said associated point responsive to said set pressure and said set time on a given location on said touchpad.

2. The method of claim 1 wherein the touchpad is caused to reset after the mouse cursor on the screen has made its jump.

3. The invention as defined in claim 1 wherein the time setting is a minimum time.

4. The invention as defined in claim 3 wherein the time setting is about one second.

5. The invention as defined in claim 1 wherein the pressure setting is set to a high value.

6. The invention as defined in claim 1 wherein said cursor is moved to said associated point without being between said starting point and said associated point.

7. The invention as defined in claim 1 wherein said determined point on said touch pad is an average point.

8. A computer readable storage medium having computer program code stored therein, the program code comprising instructions which, when executed, causes a mouse cursor in a computer system to jump from one point on a screen to another point on said screen, and wherein a mouse cursor is displayed on said screen, and a touchpad is operatively connected to said screen, comprising the steps of:

associating a coordinate system on said touchpad with a coordinate system on said screen to generate locations on said screen corresponding to given locations on said touchpad;

pressure setting for a valid response from said touchpad to said screen at each coordinate location on the touchpad;

time setting for a valid response from said touchpad to said screen; and

determination of a point with reference to a finger on said touchpad and, thus, an associated point on said screen for the movement of the mouse cursor to said associated point and said associated point on said screen responsive to said set pressure and said set time on a given location on said touchpad.

9. A system comprising a computer with a screen and with a mouse cursor thereon, and a touchpad operatively connected to said screen;

circuitry which coordinates a system on said touchpad with a coordinate system on said screen to generate locations on said screen corresponding to given locations on said touchpad,

settings for the pressure for a valid response from said touchpad to said screen;

settings for the time for a valid response from said touchpad to said screen; and

said circuitry in said computer for the determination of a point with reference to a finger on said touchpad and, thus, an associated point on said screen for the movement of the mouse cursor to said associated point, said starting point on said screen responsive to said set pressure and said set time on a given location on said touchpad.

10. The invention as depicted in claim 9 wherein said circuitry is the code.

11. The computer system of claim 9 wherein the touchpad is caused to reset after the cursor on the screen has made its jump.

12. The computer system as defined in claim 9 wherein the time setting is about one second.

13. The invention as defined in claim 9 wherein the pressure setting is set to a high level.

14. The invention as defined in claim 9 wherein said cursor is moved to said associated point without being between said starting point and said associated point.

15. The invention as defined in claim 9 wherein said determined point on said touch pad is an average point.

16. The invention as defined in claim 9 wherein said cursor is moved to said associated point without being between said starting point and said associated point.

17. The invention as defined in claim 9 wherein said determined point on said touch pad is an average point.

18. A method comprising:

providing computer executable program code to be deployed to and executed on a computer system for;

causing a mouse cursor in a computer system to jump from one point on a screen to another point on said screen, and wherein a mouse cursor is displayed on said screen, and a touchpad is operatively connected to said screen, comprising the steps of;

associating a coordinate system on said touchpad with a coordinate system on said screen to generate locations on said screen corresponding to given locations on said touchpad;

setting pressure for a valid response from said touchpad to said screen at each coordinate location on the touchpad;

setting the time for a valid response from said touchpad to said screen; and

determining a point with reference to a finger on said touchpad and, thus, an associated point on said screen for the movement of the mouse cursor to said associated point responsive to said set pressure and said set time on a given location on said touchpad.

19. The invention as defined in claim 18 wherein said cursor is moved to said associated point without being between said starting point and said associated point.

20. The method of claim 18 wherein the touchpad is caused to reset after the mouse cursor on the screen has made its jump.
