Abstract

A method for drawing shapes includes receiving first input from a touch screen display indicating a first user touch continuing for a first touch time delay, then subsequent to said first touch time delay, receiving second input from the display indicating a second user touch in a pattern on the display. The method includes correlating the first input and the second input with a drawing shape. The drawing shape includes a standard geometric shape. The method includes forming an image on the display that corresponds to the drawing shape.

First claim

What is claimed is:

1. A method comprising:
receiving first input from a touch screen display of an electronic device indicating a first user touch of a user at a fixed location on the touch screen display continuing for a first touch time delay;
sending a confirmation signal to the user in response to continuing the first user touch at a fixed location for the first touch time delay;
subsequent to said first touch time delay, receiving second input from the display indicating a second user touch in a pattern on the display;
correlating the first input and the second input with a drawing shape, the drawing shape comprising a standard geometric shape; and
forming an image on the display that corresponds to the drawing shape.

2. The method of claim 1 , wherein orientation and sizing of the image is based on the first input and the second input and comprises one or more of:
a position of the first user touch;
a position of the second user touch; and
subsequent user movement in the pattern and associated with the second user touch.

3. The method of claim 1 , further comprising:
receiving additional input from the display indicating one or more of:
further movement associated with the second user touch; and
movement associated with the first user touch; and

forming at least a portion of the image based on the additional input after correlating the first input and the second input to a drawing shape and forming at least a portion of the image from one or more of the first input and the second input.

4. The method of claim 1 , further comprising:
receiving input from the display indicating a stoppage of movement associated with one or more of the first user touch and the second user touch wherein the first user touch maintains a fixed position and the second user touch maintains a fixed position;
determining that a stoppage time delay has expired;
receiving additional input after the stoppage time delay, the additional input indicating one or more of movement associated with the first user touch and movement associated with the second user touch; and
one or more of resizing and repositioning the image in response to the additional input.

5. The method of claim 4 , further comprising sending a resize/reposition signal to the user in response to expiration of the stoppage time delay and prior to receiving the additional input.

6. The method of claim 1 , wherein the image comprises a first image and wherein the first user touch comprises movement and maintaining the first user touch in a fixed position after the movement, and further comprising forming a second image on the display based on the movement associated with the first user touch and prior to maintaining the first user touch in a fixed position, wherein the first touch time delay starts in response to maintaining the first user touch in the fixed position.

7. The method of claim 6 , wherein the first image is a continuation of the second image.

8. The method of claim 6 , wherein the drawing shape comprises an arc and wherein the second image comprises a preliminary shape comprising a first point located at a position on the display associated with commencement of the first user touch and a second point located at a position on the display associated with the maintaining the first user touch in a fixed position and wherein the second user touch is on the second image, wherein the first image in the form of an arc is formed by subsequent user movement associated with the second user touch in a direction away from a line bisecting the first point and the second point.

9. The method of claim 1 , wherein the drawing shape comprises a line and wherein the pattern, comprising subsequent user movement after the second user touch, comprises at least a movement that is toward a position of the first user touch, wherein receiving input from the display indicating subsequent user movement away from the position of the first user touch after movement toward the position of the first user touch is used to determine position, direction and length of the line.

10. The method of claim 1 , wherein the drawing shape comprises a semicircle and wherein the pattern, comprising subsequent user movement after the second user touch, in a circular movement, wherein forming an image on the display comprises forming a semicircle starting at the second user touch wherein the semicircle ends at a position corresponding to a position where movement associated with the second user touch ends by one of stopping movement associated with the second user touch and ending the second user touch.

11. The method of claim 1 , wherein the drawing shape comprises a circle and wherein the pattern, comprising subsequent user movement after the second user touch, comprises a circular movement in a first direction in conjunction with circular movement in the first direction subsequent to the first user touch and associated with the first user touch, wherein forming an image on the display comprises forming a circle with a diameter corresponding to a position of the first user touch and a position of the second user touch.

12. A program product comprising a non-transitory computer readable storage medium that stores executable code that is executable by a processor, the executable code comprising code to perform:
receiving first input from a touch screen display of an electronic device indicating a first user touch of a user at a fixed location on the touch screen display continuing for a first touch time delay;
sending a confirmation signal to the user in response to continuing the first user touch at a fixed location for the first touch time delay;
subsequent to said first touch time delay, receiving second input from the display indicating a second user touch in a pattern on the display;
correlating the first input and the second input with a drawing shape, the drawing shape comprising a standard geometric shape; and
forming an image on the display that corresponds to the drawing shape.

13. The program product of claim 12 , the executable code further comprises code to perform:
receiving input from the display indicating a stoppage of movement associated with one or more of the first user touch and the second user touch wherein the first user touch maintains a fixed position and the second user touch maintains a fixed position;
determining that a stoppage time delay has expired;
receiving additional input after the stoppage time delay, the additional input indicating one or more of movement associated with the first user touch and movement associated with the second user touch; and
one or more of resizing and repositioning the image in response to the additional input.

14. An apparatus comprising: a first input module that receives first input from a touch screen display of an electronic device indicating a first user touch of a user at a fixed location on the touch screen display continuing for a first touch time delay; a confirmation module that sends a confirmation signal to the user in response to continuing the first user touch at a fixed location for the first touch time delay; a second input module that, subsequent to said first touch time delay, receives second input from the display indicating a second user touch in a pattern on the display; a correlation module that correlates the first input and the second input with a drawing shape, the drawing shape comprising a standard geometric shape; and an image module that forms an image on the display that corresponds to the drawing shape, wherein said modules comprise one or more of a hardware circuit, a programmable hardware device and a processor whic
