Abstract

A computer in which entry of data from an area provided on a display, touch screen or the like is accomplished by the provision of a "soft keyboard". Misentry of data is avoided by providing for the adjustment of the input by raising the area of input by a fixed percentage of the size of the target soft key.

Claims

1. A computer system comprising:

a processor for processing digital data;

memory coupled to said processor for storing digital data;

a display device coupled to said processor and said memory to display information derived from digital data processed by said processor;

an input device for selecting information on said display; and

a control program stored in said memory and accessible by said processor to direct the processing of digital data by said processor;

said control program and said processor cooperating, when said control program is executing on said processor, to;

(a) display a soft keyboard formed by a plurality of adjoining cells on said display device, each of said cells representing a soft key and having an indicated zone; and

(b) adjusting said information sensed as selected by said input device by shifting the indicated zone of sensed selection by a percentage of the size of said soft key displayed on said display device.

2. A computer system as claimed in claim 1 wherein said input is further adjusted for parallax.

3. A computer according to claim 1 or 2 wherein said control program and said processor cooperate, when said control program is executing on said processor, in defining a selectable escape sequence by which a user may terminate the adjustment of said information by said fixed percentage.

4. A display generating and input selection sensing system comprising:

a processor processing digital data;

memory coupled to said processor for storing digital data;

said processor and said memory cooperating in supplying digital data driving a display of visual images on a display device;

an input device capable of indicating selectable areas on said display device; and

a control program stored in said memory and accessible by said processor to direct the processing of digital data by said processor;

said control program and said processor cooperating, when said control program is executing on said processor, to;

(a) supply digital data driving a display of at least one selectable item defined by a predetermined cell in a zone of said display having an entry selectable by a user indicating said zone; and

(b) adjust a data entry selected by said input device by shifting the indicated zone of sensed selection by a percentage of the size of said soft key displayed on said display device.

5. A display generating system as claimed in claim 4 wherein said data entry selected by said input device is adjusted for parallax by said control program and said process cooperating when said control program is executed.

6. A system as claimed in claim 4 or 5 wherein said data entry adjustment by a percentage of the size of said soft key can be selectively initiated or terminated.

7. A method for interpreting input to a computer system comprising the steps of:

displaying a set of soft keys on a display device;

capturing input from an input device;

shifting said input representing said soft key by a percentage of said soft key'"'"'s physical size, and;

passing said shifted input to an application program.

8. The method as claimed in claim 7, further comprising the step of adjusting said input for parallax prior to passing said adjusted input to an application program.

9. A soft keyboard apparatus comprising:

a display device coupled to a computer processor;

means for displaying one or more soft key cells comprising said soft keyboard on said display device.;

means, coupled to said means for displaying, for selecting input of one or more soft key cells of said soft keyboard; and

,

means for shifting said selected input by a percentage of the cell size of said selected soft key.

10. A soft keyboard apparatus as claimed in claim 9 wherein said means for selecting comprises a mouse, trackpoint, or trackball.

11. A soft keyboard apparatus as claimed in claim 9 wherein said means for selecting comprises a pen.

12. A soft keyboard apparatus as claimed in claim 9 wherein said means for selecting comprises a touch sensitive screen.

13. A computer system comprising:

a processor for processing digital data;

memory coupled to said processor for storing digital data;

a display device coupled to said processor and said memory to display information derived from digital data processed by said processor;

an input device for selecting information on said display; and

a control program stored in said memory and accessible by said processor to direct the processing of digital data by said processor;

said control program and said processor cooperating, when said control program is executing on said processor, to;

(a) display a soft key formed by one or more cells on said display device, each of said cells representing a soft button and having an indicated zone; and

(b) adjusting said information sensed as selected by said input device by shifting the indicated zone of sensed selection by a percentage of the size of said soft button displayed on said display device.

14. A computer system as claimed in claim 13 wherein said input is further adjusted for parallax.

15. A soft button apparatus comprising:

a display device coupled to a computer processor;

means for displaying one or more soft button cells on said display device.;

means, coupled to said means for displaying, for selecting input of one or more soft button cells; and

,

means for shifting said selected input by a percentage of the cell size of said selected soft button.
