S210, the electronic pen acquires motion information and posture information of the electronic pen, and relative position information between the electronic pen and the screen of the display device.

In one embodiment, the electronic pen can first obtain the motion information of the body, and when the motion information satisfies the preset conditions, that is, when the electronic pen is in the ink-splashing state, obtains the posture information of the body and the screen of the body and the display device. relative position information, thereby reducing the data acquisition pressure of the electronic pen.

The motion information may include acceleration, for example, the acceleration of the electronic pen on the X axis, the Y axis, and the Z axis in the space rectangular coordinate system centered on the electronic pen. The attitude information may include an included angle, for example, an included angle between the electronic pen and the X axis, the Y axis, and the Z axis in the space rectangular coordinate system centered on the electronic pen. The relative position information is used to represent the relative position information relationship between the electronic pen and the display device, and may include relative distance and relative direction, such as the distance and direction of the electronic pen relative to the screen of the display device when the screen of the display device is used as a reference point.

Exemplarily, the electronic pen may acquire the acceleration of the electronic pen in real time, and when the magnitude of the acceleration is greater than or equal to a preset acceleration threshold, acquire attitude information and relative position information. It can be understood that the preset acceleration threshold can be flexibly set according to the actual situation, which is not limited here. In this way, by monitoring the acceleration, it can be accurately determined whether the electronic pen is in the state of splashing ink painting.

In a specific embodiment, the electronic pen can collect the acceleration of the electronic pen through a gyroscope to generate an acceleration curve. As shown in Figure 3, when the acceleration curve exceeds the preset acceleration threshold, the angle of the electronic pen is collected by the gravity sensor, and the electronic pen collected by the front camera, TOF module or dot matrix projector of the display device is obtained from the display device. The relative distance and relative orientation to the screen of the display device.

Taking the relative distance and relative direction captured by the front camera as an example, the display device can capture the image of the electronic pen through the front camera, and determine the relative distance and relative direction between the electronic pen and the screen of the display device according to the size and position of the electronic pen in the image.

S220, the electronic pen determines the ink splash image information according to the motion information, the posture information and the relative position information.

In one embodiment, the ink splash image information may include the display position, display shape and display size of the ink droplets.

The electronic pen can first determine the initial speed of the ink droplet, that is, the speed at which the ink droplet leaves the electronic pen, according to the motion information and the posture information. And according to the relative position information and the initial velocity, the flight time of the ink droplets is determined. According to the relative position information, initial speed and flight time, determine the end position of the ink droplet on the plane where the screen is located. Then it is determined whether the end position is located in the screen, that is, it is determined whether the ink droplet falls on the screen. In the case where the end position is located on the screen, the end position is determined to be the display position of the ink drop. Then, according to the initial speed and the flight time, the termination speed of the ink droplet falling on the display position is determined, that is, the speed at which the ink droplet falls on the screen. Therefore, according to the termination speed, the display shape and display size of the ink droplets are determined, and the ink splash image information used to characterize the ink splash image is accurately determined.

As an example, the electronic pen may first calculate the first velocity component, the second velocity component and the third velocity component of the termination velocity. The first velocity component is the velocity component of the final velocity in the first direction, the second velocity component is the velocity component of the final velocity in the second direction, and the third velocity component is the velocity component of the final velocity in the third direction. The first direction and the second direction are located on the plane where the screen is located, the third direction is perpendicular to the plane where the screen is located, and the first direction and the second direction and the third direction are perpendicular to each other. Then, the displayed shape of the ink droplet is determined according to the first velocity component and the second velocity component, and the displayed size of the ink droplet is determined according to the third velocity component. In this way, the display shape and display size of the ink droplets can be accurately determined according to the velocity components in different directions.

From the preset correspondence between the third velocity component and the display size, find the display size corresponding to the third velocity component, and use the display size as the display size of the ink droplet.

In the embodiment of the present application, the electronic pen can determine the ink splash image information according to the motion information and posture information of the electronic pen, and the relative position information of the electronic pen and the screen of the display device, and send the ink splash image information to the display device. Thus, the display device can display the ink splatter image represented by the ink splatter image information. In this way, ink splash painting can be realized when using the electronic pen, so as to meet the user's demand for ink splash painting and improve the user's use experience.

The display method provided by the embodiment of the present application is described in detail below with reference to a specific example, and the details are as follows:

Step 1. The electronic pen collects the acceleration of the electronic pen in the space rectangular coordinate system centered on the electronic pen in real time through the built-in gyroscope, and records the acceleration collected in the first time period, wherein the first time period is when the magnitude of the acceleration is greater than or a time period equal to the preset acceleration threshold. Then, according to the acceleration in the first period of time and the duration of the first period of time, the size of the initial velocity of the ink droplets is calculated.

Step 2: The electronic pen collects the angle of the electronic pen in the space rectangular coordinate system centered on the electronic pen through the built-in gravity sensor in the first time period, and determines the direction of the initial speed of the ink drop according to the angle.

Step 3: The electronic pen acquires an image of the electronic pen from the display device by the display device in the first period of time, and determines the relative distance and relative direction of the electronic pen and the display device according to the size of the electronic pen in the image.

Step 4. The electronic pen establishes a space rectangular coordinate system with the display device as the center. The coordinate origin can be the center of the screen of the display device, the X axis can be the width direction of the screen, the Y axis can be the length direction of the screen, and the Z axis can be perpendicular to the screen. The orientation of the plane on which the screen is located. It can be understood that the X axis, the Y axis, and the Z axis of the space rectangular coordinate system centered on the display device are the first direction, the second direction, and the third direction, respectively.

Step 5. The electronic pen performs coordinate system conversion on the initial speed, from the space rectangular coordinate system centered on the electronic pen to the spatial rectangular coordinate system centered on the display device, and determines the ink droplet according to the relative distance and relative direction. The coordinates of the starting point in the space Cartesian coordinate system centered on the device.

Step 6, the electronic pen calculates the flight time of the ink droplets according to the starting point coordinates and the converted initial speed, and calculates the ink droplets in the space Cartesian coordinate system centered on the electronic pen according to the starting point coordinates, the converted initial speed and the flight time. The end point coordinate in is the end point position. If the end point coordinate is located on the screen, the end point coordinate is determined as the display position of the ink drop. Then, according to the converted initial speed and flight time, the termination speed of the ink droplet falling on the display position is calculated. Therefore, according to the termination speed, the display shape and display size of the ink droplets are determined, and the ink splash image information including the display position, display shape and display size of the ink droplets is obtained. It can be understood that, the number of ink droplets may be determined by the acceleration of the electronic pen, and there may be more than one, which is not limited herein.

由于墨滴飞出时只受重力影响，所以

Exemplarily, when the screen of the display device is placed horizontally, the coordinates of the starting point of the ink droplet may be D ₀ : (x ₀ , y ₀ , z ₀ ), and the coordinates of the end point may be D ₁ : (x ₁ , y ₁ , 0) , the converted initial velocity of the ink droplet can be

The termination velocity of the ink droplet can be

in,

Since the ink droplets are only affected by gravity when they fly out,

The flight time can be calculated according to a first formula, wherein the first formula can be as follows:

where T is the time of flight and g is the acceleration of gravity.

Then x ₁ can be calculated according to the second formula, and y ₁ can be calculated according to the third formula, wherein the second formula and the third formula can be as follows:

x ₁ = x ₀ +V _x0 T (2)

y ₁ =y ₀ +V _y0 T (3)

It can be understood that the center of the screen is the origin of the entire coordinate system, and the coordinates of the screen boundary can be obtained, and then it can be determined whether D ₁ : (x ₁ , y ₁ , 0) is located in the screen of the display device. In the case where D ₁ : (x ₁ , y ₁ , 0) is located within the screen of the display device, V _z1 can be calculated according to a fourth formula, where the fourth formula can be as follows:

V _z1 =V _z0 +gT (4)

Next, the display shape of the ink droplet may be determined according to V _x0 and V _y0 , and the display size of the ink droplet may be determined according to V _z1 , to obtain image information including the ink splash.

Step 7. The electronic pen sends ink splashing information to the display device through Bluetooth.

Step 8: The display device receives the ink splash information sent by the display device through Bluetooth, and displays the ink splash image represented by the ink splash information.
