Abstract

Methods and electronic devices for displaying a particle effect are described. One method includes receiving an input on an area of a display screen, the area having a color. A main particle color is set based on the color, and then a secondary particle color is set based on the main particle color. A plurality of moving particles are displayed, the moving particles moving around the input area, and each of the plurality of moving particles has a color on a spectrum from the main particle color to the secondary particle color.

Claims

1. A method for an electronic device, comprising:

receiving an input on an area on a display screen of the electronic device, the area having at least one color;

setting a main particle color based on one or more of the at least one color;

setting a secondary particle color based on the main particle color; and

generating a plurality of moving particles on the display screen, the moving particles moving around the input area, wherein each of the plurality of moving particles has a color on a spectrum from the main particle color to the secondary particle color.

2. The method of claim 1, wherein the shape of the moving particles is at least one of circular, triangular, quadrilateral, star or snowflake shape.

3. The method of claim 1, wherein the shape of the moving particles is three-dimensional.

4. The method of claim 1, wherein the shape of the moving particles based on at least one of a setting and the input.

5. The method of claim 1, wherein the number of moving particles based on at least one of a setting and the input.

6. The method of claim 1, wherein the movement of the moving particles based on at least one of a setting and the input.

7. The method of claim 1, wherein the direction and speed of the moving particles based on at least one of a setting and the input.

8. The method of claim 1, wherein the one or more sizes of the moving particles based on at least one of a setting and the input.

9. The method of claim 1, wherein the plurality of moving particles disappear from the display screen.

10. The method of claim 9, wherein the duration that each of the plurality of moving particles remain on the display screen based on at least one of a setting and the input.

11. The method of claim 1, wherein setting a secondary particle color comprises:

changing at least one of a hue, saturation, and brightness of the main particle color.

12. The method of claim 1, wherein the color of each of the plurality of moving particles is randomly selected on the spectrum from the main particle color to the secondary particle color.

13. The method of claim 1, wherein the input is a drag or a slide and pluralities of moving particles are continuously generated based on a current location of input on the display screen.

14. The method of claim 1, wherein the input is a drag or a slide and at least one of one or more directions of the moving particles and one or more speeds of the moving particles are based on at least one of the direction and speed of the input.

15. A method for an electronic device, comprising:

receiving an input on an area on a display screen of the electronic device, the input having a duration, a pressure intensity, a gesture type, and an input tool;

setting, based on at least one of the input duration, pressure, gesture type, and input tool, at least one of a range of moving particle sizes, a number of moving particles, one or more moving particle shapes, and a duration of each moving particle; and

generating a plurality of moving particles on the display screen, the moving particles moving around the input area, wherein the plurality of moving particles has at least one of the set number of moving particles, the set range of moving particle sizes, the set one or more moving particle shapes, and the set duration of each moving particle.

16. The method of claim 15, wherein the gesture type has a direction and speed, and wherein the at least one of a range of moving particle sizes, a number of moving particles, one or more moving particle shapes, and a duration of each moving particle are set based on at least one of the direction and speed of the input gesture.

17. The method of claim 15, wherein the input tool comprises at least one of a human body part and a stylus.

18. An electronic device comprising:

a display screen;

a touch input unit; and

one or more processors, the one or more processors capable of performing the steps of;

when an input is received on an area on the display screen, the area having at least one color, setting a main particle color based on one or more of the at least one color;

setting a secondary particle color based on the main particle color; and

generating a plurality of moving particles on the display screen, the moving particles moving around the input area, wherein each of the plurality of moving particles has a color on a spectrum from the main particle color to the secondary particle color.

19. The electronic device of claim 18, wherein the display screen comprises the touch input unit.

20. An electronic device comprising:

a display screen;

a touch input unit; and

one or more processors, the one or more processors capable of performing the steps of;

when an input is received on an area on the display screen, the input having a duration, a pressure intensity, a gesture type, and an input tool, setting, based on at least one of the input duration, pressure, gesture type, and input tool, at least one of a range of moving particle sizes, a number of moving particles, one or more moving particle shapes, and a duration of each moving particle; and

generating a plurality of moving particles on the display screen, the moving particles moving around the input area, wherein the plurality of moving particles has at least one of the set number of moving particles, the set range of moving particle sizes, the set one or more moving particle shapes, and the set duration of each moving particle.
