[0029] In order to better understand the technical solution of the present invention, the embodiments provided by the present invention are described in detail below with reference to the accompanying drawings.

[0030] The present invention provides a smart pen, such as Figure 1 and Figure 3 As shown, it comprises: a pen body 1 and a pen core 2, wherein the pen core 2 is arranged in the pen body 1, and the writing end of the pen core 2 protrudes from the front end of the pen body 1, and a gyroscope 11 and a main control board 12 are arranged in the pen body 1, and the pen core 2 is respectively connected to the gyroscope 11 and the main control board 12 by signal, and the main control board 12 is connected to the gyroscope 11 by signal;

[0031] The gyroscope is used to record the motion signal of the pen body.

[0032] In this embodiment, preferably, the gyroscope 11 is a six-axis gyroscope sensor, and the six-axis gyroscope sensor includes both a gyroscope sensor and an accelerometer sensor. The gyroscope sensor records the angular displacement and angular velocity of the pen body movement, and the accelerometer sensor records the linear acceleration of the pen body. The motion signal includes the angular displacement information, angular velocity information and linear acceleration information when the pen body moves. Preferably, the gyroscope can also be other nine-axis or other multi-axis gyroscope sensors that can sense all-round dynamic information of the pen body tilting left and right, tilting forward and backward, and swaying left and right.

[0033] The main control board is used to receive the motion signal, and generate a cursor control signal after performing calculation processing on the motion signal, and control the cursor movement of the intelligent terminal through the cursor control signal.

[0034] On the basis of the above embodiments, in other embodiments, further, a pressure sensor 13 and a photosensitive camera 14 are provided in the pen body 1, the pressure sensor 13 is signal-connected to the pen core 2 and the photosensitive camera 14 respectively, the pressure sensor 13 is signal-connected to the gyroscope 11, and the gyroscope is signal-connected to the photosensitive camera 14.

[0035] The pen core 2 is used for writing tracks.

[0036] The pressure sensor is used to record the pressure signal of the writing end of the pen core 2 and activate the photosensitive camera.

[0037] The photosensitive camera is used to record the writing track information of the pen core 2.

[0038] The main control board is used to receive the motion signal, pressure signal and writing trajectory information, and generate a cursor control signal after performing calculations based on the motion signal, pressure signal and writing trajectory information, and control the cursor movement of the smart terminal through the cursor control signal.

[0039] In this embodiment, preferably, the pressure signal may be a pressure magnitude signal or a pressure frequency signal, and the functions of the cursor left and right keys are realized by the pressure magnitude signal or the pressure frequency signal.

[0040] When the pressure signal is a pressure size signal, the pressure sensor senses the pressure size (the movement of the pen here can be lifting or dropping), and the pressure sensor transmits the sensed pressure force signal to the main control board, and the pressure value is calculated by the main control board. If the pressure value falls within the pressure range of the left and right keys (it can be set to pressure and no pressure, or pressure and two pressures, or directly set by the pressure range value), the pressure signal is converted into cursor left and right key signals through calculation by the main control board and transmitted to the smart terminal, and the cursor of the smart terminal can execute the left and right mouse key functions.

[0041] When the pressure signal is a pressure frequency signal, the pressure sensor senses the pressure frequency and generates a pressure signal. The main control board receives the pressure signal and generates a cursor control signal after performing calculations based on the pressure signal. The left and right keys of the cursor of the smart terminal are controlled by the cursor control signal.

[0042] The control mode of the control signal can be set to a right mouse button when the pen tip is pressed once, and a left mouse button when the pen tip is pressed twice; or set to a right mouse button when the pen tip is pressed an odd number of times, and a left mouse button when the pen tip is pressed an even number of times; or set to a left mouse button when the pen tip falls down and touches a contact object and there is pressure, and a right mouse button when the pen tip is lifted and leaves the contact object, that is, when the pressure sensor senses pressure, it is a left mouse button, and when the pressure sensor does not sense pressure, it is a right mouse button. In other embodiments, the calculation method of the main control board can also be changed to use the pressure value range of the pen tip as the left and right mouse buttons.

[0043] In this embodiment, preferably, the main control board 12 is a PCB integrated circuit board, and the main control board 12 includes an operator and a cursor controller for controlling the direction of the cursor, the operator is signal-connected to the cursor controller, and the operator is signal-connected to the gyroscope 11 and the pressure sensor 13 respectively.

[0045] The cursor controller is used to control the movement of the cursor of the intelligent terminal according to the cursor control signal. Preferably, the intelligent terminal is a computer, a mobile phone or other electronic product with a display screen.

[0046] In this embodiment, preferably, the gyroscope 11 is a six-axis gyroscope sensor, which includes both a gyroscope sensor and an accelerometer sensor. The gyroscope determines the posture of the pen body, that is, it can sense the acceleration of the three-axis directions of the pen body in three-dimensional space, and can also sense the all-round dynamic information of the pen body's left and right tilt, front and back tilt, and left and right swing, that is, all states of the pen body's movement, that is, it can detect the pen body's angular rotation and balance, and sense the movement direction of the pen body's angular acceleration.

[0047] In this embodiment, preferably, the pressure sensor 13 is a 1024-order pressure sensor. Preferably, the 1024-order pressure sensor has the characteristics of high sensitivity, fast reading speed, high resolution, changeability, repeatability and easy storage. The use of a 1024-order pressure sensor can better and faster sense the pressure when the pen tip contacts an object, and quickly generate a pressure-sensing signal and transmit it to components such as a camera and a computing unit. It also reduces time errors and better ensures the accuracy of the pen body simulating the mouse function.

[0048] In this embodiment, preferably, the photosensitive camera 14 is a photosensitive camera capable of continuously photographing the note track. The photosensitive camera is connected to the pressure sensor signal. When the pressure sensor senses the writing pressure of the pen tip, it generates a pressure-sensitive signal and turns on the camera. The camera continuously photographs the handwriting track to form track information. The writing track of the pen core falls on the code point. The code point technology is a dot matrix technology commonly used in the field of smart pens. The dot matrix technology mainly includes the coding theory of locating the absolute coordinates of the plane in a digital dot matrix manner, and uses its coding theory to propose a solution to the information recognition technology of identifying the drawing and the paper surface. Each code point on the paper has an absolute coordinate, so the distance between the code points is also the distance between the absolute coordinates. This distance information can be converted into the moving distance of the cursor by the operator together with the motion signal generated by the gyroscope. Therefore, the dot matrix technology can effectively and accurately record the trajectory information of the smart pen. The absolute coordinate value of the code point and the motion signal of the gyroscope are calculated by the operator to obtain the moving distance of the cursor.

[0049] In this embodiment, preferably, a wireless signal transceiver is provided on the pen body 1, and the wireless signal transceiver is signal-connected to the main control board 12, and the communication chip on the main control board is signal-connected to the wireless signal transceiver, and the cursor controller sends the cursor control signal to the processor on the main control board. Preferably, the processor is an ARM processor, a 32-bit reduced instruction set (RISC) processor architecture, and the processor sends the cursor control signal to the communication chip after processing, and then the wireless signal transceiver receives the cursor signal in the communication chip, and the wireless signal transceiver connects the smart pen to the corresponding smart terminal wirelessly, so that the smart pen can fully simulate the operation of the mouse in addition to the traditional writing function, so that it can imitate the function of the mouse when used in conjunction with a computer, thereby making the function of the smart pen more extensive and more convenient for users to use.

[0050] In this embodiment, preferably, the wireless signal transceiver may be a wireless signal transceiver using Bluetooth, wireless wide area network WWAN, wireless USB, optical fiber or infrared technology.

[0051] In this embodiment, preferably, a data line interface for signal transmission is provided on the pen body 1, and the data line interface is connected to the main control board 12. The data line interface is connected to the main control board, and the cursor controller sends the cursor control signal to the processor on the main control board. Preferably, the processor is an ARM processor, a 32-bit reduced instruction set (RISC) processor architecture, and the processor sends the cursor control signal to the communication chip after processing. The data line interface is connected via a data line to connect the smart pen to the corresponding smart terminal, so that the smart terminal receives the cursor control signal through the data line transmission to realize the function of the smart pen simulating a mouse.

[0052] The present invention also provides a method for realizing a mouse function of a smart pen, comprising a pen body 1 and a pen core 2, wherein the pen core 2 is arranged in the pen body 1, the writing end of the pen core 2 protrudes from the front end of the pen body 1, and a gyroscope 11 and a main control board 12 are arranged in the pen body 1, and the method comprises the following steps:

[0053] 1) The gyroscope records the motion signal of the pen body;

[0054] In this step, preferably, the motion signal is a motion direction, angular acceleration and directional acceleration signal generated when the pen body is shaken back and forth or left and right;

[0055] 2) The main control board receives the motion signal, and generates a cursor control signal after performing calculation processing on the motion signal, and controls the cursor movement of the smart terminal through the cursor control signal.

[0056] Through the above steps, when the tip of the smart pen touches any object, the tip of the pen is kept in place and the pen body is shaken arbitrarily. The moving distance of the pen body is converted into a cursor control signal through the main control board, and the cursor movement of the smart terminal is controlled by the cursor control signal, thereby realizing the function of controlling the cursor movement of the smart terminal by shaking the pen body of the smart pen.

[0057] In this embodiment, preferably, the main control board receives the motion signal, calculates the displacement distance of the cursor according to the motion signal and the absolute coordinate value of the code point, and generates a cursor control signal according to the displacement distance of the cursor, and controls the cursor movement of the smart terminal through the cursor control signal.

[0058] The absolute coordinate value of the code point involves a dot matrix technology, which mainly includes a coding theory for locating the absolute coordinates of a plane in a digital dot matrix manner, and uses the coding theory to propose a technology for identifying information between drawings and paper. Each code point on paper has an absolute coordinate, so the distance between code points is also the distance between absolute coordinates. This distance information can be converted into a cursor movement distance by an operator together with the motion signal of a gyroscope, and a cursor control signal is generated according to the displacement distance of the cursor, and the cursor movement of the smart terminal is controlled by the cursor control signal.
