Abstract

A method of emulating a flat tip brush, said method comprising (a) at a given time, identifying first and second points of contact on a touch sensitive surface; (b) interpolating a line between the first and second points, the line having line data comprising at least a length and an angle relative to the screen; (c) recording the first and second points and the line data; (d) reiterating steps (a)-(c) for at least one subsequent time to determine a plurality of the first points and a plurality of the second points and a plurality of the lines; and (e) displaying on a display screen an image defined by the first points, by the second points and/or by the lines between the first and second points.

Claims

1. A method of emulating a flat tip brush, said method comprising:

(a) at a given time, identifying first and second points of contact on a touch-sensitive surface;

(b) interpolating a line between said first and second points, said line having line data comprising at least a length and an angle relative to said touch-sensitive surface;

(c) recording said first and second points and said line data;

(d) reiterating steps (a)-(c) for at least one subsequent time to determine a plurality of said first points and a plurality of said second points and a plurality of said lines; and

(e) displaying on a display screen an image defined by said first points, by said second points and/or by said lines between said first and second points.

2. The method of claim 1, wherein said first point is made with a first finger and said second point is made with a second finger.

3. The method of claim 2, further comprising prior to step (a) displaying on said touch-sensitive surface a first and second suggested points for contacting said first and second fingers and at least one arrow indicating a suggested path to move said first and second fingers.

4. The method of claim 3, wherein said suggested path defines an alphanumeric.

5. The method of claim 4, wherein said alphanumeric is calligraphic.

6. The method of claim 1, wherein said image is the space including said lines.

7. The method of claim 1, further comprising prior to step (a), prompting a user to input a desired message to be displayed, recording said desired message, and displaying at least part of said desired message for said user to emulate.

8. The method of claim 1, wherein said touch-sensitive surface is connected to a digital processor and said digital processor is connected to memory.

9. The method of claim 8, wherein said display screen and said touch-sensitive surface are integrated.

10. The method of claim 9, wherein said touch-sensitive surface, display screen, processor and memory being integrated into a single device.

11. The method of claim 10, wherein said device is a tablet.

12. The method of claim 11, wherein said tablet is an IPAD®

.

13. A non-transitory computer-readable medium comprising non-transitory instructions for instructing a processor operative connected to a touch-sensitive surface to execute the following steps:

(a) at a given time, identifying first and second points of contact on said touch-sensitive surface;

(b) interpolating a line between said first and second points, said line having line data comprising at least a length and an angle relative to said touch-sensitive surface;

(c) recording said first and second points and said line data;

(d) reiterating steps (a)-(c) for at least one subsequent time to determine a plurality of said first points and a plurality of said second points and a plurality of said lines; and

(e) displaying on a display screen an image defined by said first points, by said second points and/or by said lines between said first and second points.

14. A device comprising a digital processor, memory operatively connected to said processor and a touch-sensitive surface operatively connected to said processor, said memory being configured with instructions for instructing said processor to execute the following steps:

(a) at a given time, identifying a first point of contact made with a first finger and a second point of contact made with a second finger;

(b) interpolating a line between said first and second points, said line having line data comprising at least a length and an angle relative to said touch-sensitive surface;

(c) recording said first and second points and said line data;

(d) reiterating steps (a)-(c) for at least one subsequent time to determine a plurality of said first points and a plurality of said second points and a plurality of said lines; and

(e) displaying on said touch-sensitive surface an image defined by said first points, by said second points and/or by said lines between said first and second points.

15. The device of claim 14, wherein said device is a tablet.

16. The device of claim 15, wherein said tablet is an IPAD®
