Abstract

A method includes dividing a display of an electronic device into multiple regions defined by vertices, calculating time varying positions for each vertex relative to a z dimension, and composing a screen for the display that includes the varying positions for each vertex to create an animated display distortion. The distortion may occur in association with haptic effects.

Claims

1. A method comprising:

dividing a display of an electronic device into multiple regions defined by vertices;

calculating time varying positions for each vertex relative to a z dimension; and

composing a screen for the display that includes the time varying positions for each vertex to create an animated display distortion.

2. The method of claim 1 wherein composing the screen comprises adding the time varying positions for each vertex to a surface generated by an application running on the electronic device.

3. The method of claim 1 wherein the time varying positions for each vertex are calculated to provide a visual wave effect in association with haptic effects.

4. The method of claim 1 wherein the varying positions vary between enlarged and shrunken, creating a distortion in the display.

5. The method of claim 4 wherein creating varying positions utilizes a piston rod sin function.

6. The method of claim 5 wherein a length of the piston rod is varied over time.

7. The method of claim 6 wherein the length of the piston rod is varied over time in accordance with a Perlin noise pattern using a turbulence function calculated from four frequencies of noise.

8. The method of claim 7 wherein a mapping between pistons and the noise pattern shifts across the screen to create a wave effect.

9. The method of claim 1 and further comprising transitioning the animated display distortion on and off in accordance with an intensity value.

10. A machine readable storage device having instructions for execution by a processor to cause the machine to perform operations comprising:

dividing a display of an electronic device into multiple regions defined by vertices;

calculating time varying positions for each vertex relative to a z dimension; and

composing a screen for the display that includes the time varying positions for each vertex to create an animated display.

11. The machine readable storage device of claim 10 wherein the operations for composing the screen comprise adding the varying positions for each vertex to a surface generated by an application running on the electronic device.

12. The machine readable storage device of claim 10 wherein the time varying positions for each vertex are calculated to provide a visual wave effect in association with haptic effects.

13. The machine readable storage device of claim 10 wherein the varying positions vary between enlarged and shrunken, creating a distortion in the display in association with haptic effects.

14. The machine readable storage device of claim 13 wherein creating varying positions utilizes a piston rod sin function.

15. The machine readable storage device of claim 14 wherein a length of the piston rod is varied over time in accordance with a Perlin noise pattern using a turbulence function calculated from four frequencies of noise.

20. The device of claim 15 wherein a length of the piston rod is varied over time in accordance with a Perlin noise pattern using a turbulence function calculated from four frequencies of noise.

16. A device comprising:

a processor;

a display coupled to the processor; and

a memory device coupled to the processor and having a program stored thereon for execution by the processor to perform operations comprising;

dividing the display into multiple regions defined by vertices;

calculating time varying positions for each vertex relative to a z dimension; and

composing a screen for the display that includes the time varying positions for each vertex to create an animated display distortion.

17. The device of claim 16 wherein composing the screen comprises adding the time varying positions for each vertex to a surface generated by an application running on the electronic device.

18. The device of claim 16 wherein the varying positions vary between enlarged and shrunken, creating a distortion in the display in association with haptic effects.

19. The device of claim 16 wherein calculating varying positions utilizes a piston rod sin function.
