Therefore, the protection scope of the present invention is not limited by the following disclosure. Limitations of specific embodiments.

Because in the prior art, the display mode of the desktop icon is boring and monotonous, the desktop display effect is not beautiful enough, and the personalization is insufficient, etc., the user will have visual fatigue, no freshness, no fun during long-term use, thus serious Affect the user experience.

The embodiment of the present invention provides a vivid and interesting desktop icon display method and device, so that the desktop will present a dynamic effect for the user to show off, and also emit the collision sound of the icons, and at the same time, the user can also change the motion state of the icons at will, which is full of interest , Bringing a lot of entertainment and good use and operation experience to users. The method and device are applicable to any intelligent terminal with a touch screen.

Example 1

Embodiment 1 of the present invention provides a vivid and interesting method for displaying desktop icons, and FIG. 1 , FIG. 2 and FIG. 3 are schematic flow charts according to the method. Obviously, when the method is applied on the smart terminal, the first collision sound and the second collision sound are pre-stored on the smart terminal; and after starting the method, as shown in Figure 1, the following steps are included:

Step 1, when entering the desktop, initialize the desktop icons, and randomly assign the same or different initial direction and initial velocity to each icon on the current desktop;

More specifically, the initialization of desktop icons includes: configuring information such as position, icon size, and quality for each icon. Wherein, in this embodiment, the position of the icon is represented by the center of the circumcircle of the icon; the size of the icon is represented by the radius of the circumscribed circle of the icon; The motion state changes, and the quality of each icon is set to 1 by default.

Step 2, real-time detection of whether there is a collision between the icons;

Step 3, if a collision between the two icons is detected, the pre-stored first collision sound is played, and the respective motion directions and speeds of the two icons after the collision are calculated according to the law of conservation of momentum and the law of conservation of energy;

Step 4, detect in real time whether the icon collides with the edge of the touch screen;

Step 5, if it is detected that an icon collides with the edge of the touch screen, the pre-stored second collision sound is played, and the icon bounces back at the speed of the collision.

Wherein, there is no sequence between step 2 and step 4; the first impact sound and the second impact sound may be the same or different. More specifically:

The specific method of randomly assigning an identical or different initial direction to each icon on the current desktop is:

Define the horizontal right direction of the touch screen as the positive direction of the x-axis, and the horizontal upward direction as the positive direction of the y-axis;

The movement direction of the icon is represented by the angle between the icon and the positive direction of the x-axis, then the range of the movement direction is [0°, 360°];

When initializing desktop icons, use a random function to assign an initial direction within [0°, 360°] to each icon on the current desktop, and the initial directions between icons are the same or different.

The specific method of randomly assigning an identical or different initial velocity to each icon on the current desktop is:

Determine the icon speed range according to the resolution of the touch screen, wherein the icon speed specifically refers to the pixel displacement of the icon per second;

When initializing desktop icons, use a random function to assign an initial velocity within the icon velocity range to each icon on the current desktop. For example, take a mobile phone as an example: if the screen width of the mobile phone is WIDTH pixels, then the speed range can be set to [WIDTH/10,WIDTH/3]; where 10 and 3 refer to the movement of WIDTH pixels. The time, so WIDTH/10 represents the speed, that is, it takes 10 seconds at the slowest to move from the far left to the far right, and 3 seconds at the fastest.

Referring to Fig. 5 and Fig. 6, it should be noted that in this embodiment, it is considered that the collision between icons and the collision between icons and the edge of the touch screen has no energy loss and is a completely elastic collision. Therefore, if If an icon collides with the edge of the touch screen, the icon will bounce back at the speed at which it collides after colliding with the edge of the touch screen; and the respective motion directions and speeds of the two icons after the collision are calculated according to the law of conservation of momentum and the law of conservation of energy. Specifically include:

When a collision between two icons is detected, a collision coordinate system is established with the line connecting the two icons as the y-axis, the collision point as the origin, and the tangent of the collision point as the x-axis;

According to the law of conservation of momentum and law of conservation of energy, the system of equations is obtained:

Calculate the respective speeds of the two icons after the collision; where m is the quality of an icon, in this embodiment, the preferred m is 1, and v ₁₀ and v ₂₀ are the speeds when the two icons collide respectively, v ₁ and v ₂ are the speeds of the two icons after they collide; that is, the equations can calculate the values of v ₁ and v ₂ ;

Since the momentum is a vector, the momentum can be decomposed orthogonally on the x-axis and y-axis, then the momentum conservation will also be satisfied on the x-axis and y-axis; that is, according to the equations:

Calculate the movement directions of the two icons after the collision; among them, θ ₁₀ and θ ₂₀ are the angles between the two icons and the positive direction of the x-axis when the two icons collide; θ ₁ and θ ₂ are the positive angles between the two icons and the x-axis after the collision. The included angle of direction, that is, the values of θ ₁ and θ ₂ can be calculated through this equation group.

Furthermore, in this embodiment, the positions of all icons are stored in an array, so during the movement of the icons, a thread is opened to handle the collision detection of the icons. When the length of the central angle of the circumscribed circle of two icons is the sum of their radii, it means that the two icons have collided together; in addition, the range of the touch screen is (0,0) (width, height), when the icon circumscribed circle When the distance between the center of the circle and the screen of the mobile phone becomes the radius of the circumscribed circle of the icon, it means that the icon has collided with the edge of the screen.

As a preferred solution, as shown in Figure 2, after step 1, it further includes:

If you press and hold an icon on the current desktop, the speed of the icon becomes zero; when you release the pressed icon directly, the icon returns to its original motion state.

If after holding down an icon on the current desktop, the icon is thrown away with a gesture of throwing away, and the new speed and direction of the icon are calculated according to the motion state of the touch point.

Specifically, in the Android system, there is a class GestureDetector.OnGestureListener that monitors gesture recognition. Through the onFling method inside, you can get the touch screen event, the event of leaving the screen, the speed in the x-axis direction and the speed in the y-axis direction when leaving the screen; Therefore, the calculation of the new speed and direction of movement of the icon according to the movement state of the touch point specifically refers to:

At the moment when the gesture is thrown, the onFling method is called to obtain the speed of the gesture in the x-axis direction and the speed in the y-axis direction, and the speed of the icon at this time can be calculated through the Pythagorean law; then through the arctangent function The movement direction of the icon at this time can be calculated.

As a further preferred solution, if the speed of the icon reaches the maximum value after the icon is thrown out, then the icon at this time automatically starts to move at a uniform deceleration until the movement of the icon reaches a preset value before starting to move at a constant speed. The preset value can be set according to the actual situation, for example, it can be set to 20pixel/s.

As a preferred solution, as shown in Figure 3, after step 1, it further includes:

Monitor the acceleration sensor of the terminal in real time to obtain the acceleration of the terminal;

Map the terminal acceleration value to the preset icon acceleration value range to obtain the icon acceleration value, and the icon acceleration direction is opposite to the terminal acceleration direction;

According to the acquired icon acceleration, make each icon on the current desktop move at a variable speed.

For example, when the terminal is shaken, due to the acceleration of the terminal, the icons on the desktop will also shake back and forth and make a corresponding collision sound. At this time, it is like shaking ice cubes in a bottle; when the terminal moves upward, When you move down or tilt to one side, the icon will move sideways, presenting a visual effect like natural gravity.

In this embodiment, preferably, the acceleration value of the icon ranges from 0 to 40 pixel/s ² (pixels per square second).

After implementing this method, the desktop of the terminal will show a dynamic effect of showing off, and the corresponding icon collision sound will be emitted. At the same time, the user can also interact with the desktop and change the motion state of the icon at will, which is full of fun and brings users A lot of entertainment and good use and operation experience.
