As shown in fig. 1, a memory 1005, which is a kind of computer-readable storage medium, may include therein an operating system, a network communication module, a user interface module, and a display program of a stylus writing.
In the terminal shown in fig. 1, the network interface 1004 is mainly used for connecting to a backend server and performing data communication with the backend server; the user interface 1003 is mainly used for connecting a client (user side) and performing data communication with the client; and the processor 1001 may be configured to call a display program of the stylus writing handwriting stored in the memory 1005, and perform the following operations:

and obtaining the writing handwriting of the touch pen according to the coding signal and the coordinate information, and displaying the writing handwriting on a display interface of the terminal equipment.
Referring to fig. 2, fig. 2 is a schematic flowchart of a first embodiment of a method for displaying handwriting of a touch pen according to the present application.
While the embodiments of the present application provide an embodiment of a method for displaying stylus writing, it should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that shown.
The display method of the handwriting of the touch pen comprises the following steps:
step S10, the terminal equipment receives a coded signal sent by the touch pen through Bluetooth, wherein the coded signal is a signal obtained by coding pressure information acquired by a pressure sensor through the touch pen; at the same time, the user can select the desired position,
the terminal device includes a touch screen computer, a touch screen television, a touch screen mobile phone, a Pad, and the like, which support the touch pen to operate.
In this application, the terminal device may establish a connection with the stylus in a wireless manner, for example, establish a connection with the stylus in a bluetooth transmission manner, so as to receive the encoded signal sent by the stylus. The coded signal is a signal obtained after the pressure information of the pressure sensor is coded by the touch pen, the pressure information is related to the force exertion condition of a user during writing, the thickness of writing handwriting presented in a display interface is represented, and the thickness is sent to the terminal equipment through the Bluetooth equipment.
Therefore, in the application, the coding signal of the coordinate information of the pen point of the touch pen in the display interface of the terminal equipment does not exist in the coding signal transmitted by the touch pen to the terminal equipment with the connection established.
Step S20, obtaining coordinate information of a touch position when the touch pen touches a display interface of the terminal equipment, wherein the coordinate information is obtained through an excitation signal emitted by the touch pen;
the coordinate information is position information corresponding to the coded signal obtained when the terminal equipment receives the coded signal, namely the coded signal and the coordinate information are mapped and stored in a one-to-one corresponding mode.
In the display interface of the terminal equipment, the coordinate information of the touch pen touch on the display interface is determined through the change of the capacitance value of the electrode detected when the touch pen touch on the display interface.
Referring to fig. 3, in the present application, the coordinate information may use a length-width boundary point of a display interface of the terminal device as a coordinate origin, use a length as an x-axis, and use a width as a y-axis to establish a coordinate system, and when it is detected that an electrode in the display interface of the terminal device changes, obtain the coordinate information of the point.
Before the step of obtaining the coordinate information of the touch position when the touch pen touches the terminal device, the method includes:
collecting an excitation signal sent by the touch pen;
and determining coordinate information of a touch position when the touch pen touches the terminal equipment according to the excitation signal.
And the excitation signal is sent to the terminal equipment through a transmitting module of the touch pen. The terminal equipment acquires the excitation signal sent by the touch pen, and then obtains the coordinate when the touch pen touches the display interface of the terminal equipment according to the excitation signal. It can be understood that, in the present application, the code signal is obtained by the touch pen by obtaining the pressure information through the pressure sensor, and the coordinate information is obtained by the terminal device, when displaying, the coordinate information corresponding to different code information is different, and thus, the corresponding handwriting thickness can be displayed at the corresponding position according to the code signal (pressure information).
And step S30, combining the coding signal and the coordinate information to obtain the writing of the touch pen, and displaying the writing on a display interface of the terminal equipment.
And after the coordinate information of the touch pen is acquired, fitting operation is performed on the coordinate information and the coding information to form writing handwriting of the touch pen, and the writing handwriting is displayed on a display interface of the terminal.
Continuing with the embodiment of step S20, in this embodiment, the terminal device may match the acquired encoded signal with the identifier of the coordinate information. For example, the terminal device identifies the coordinate information already displayed on the display interface as 0, identifies the coordinate information not displayed as 1, and when receiving the coding signal, the terminal device acquires the coordinate information currently identified as 1, and fits the coordinate information with the currently acquired coding signal to form the handwriting of the touch pen on the display interface. The terminal equipment can quickly acquire the coordinate information corresponding to the coded signal by establishing the identification, so that the handwriting of a user on the display interface of the terminal equipment by using a touch pen can be displayed in real time in the display interface.
In the application, when the terminal device receives the coding signal sent by the touch pen, the coordinate information of the display interface of the terminal device touched by the touch pen is obtained, and then the writing handwriting of the touch pen on the display interface of the terminal device is obtained according to the coordinate information and the coding signal. The writing handwriting of the touch pen on the terminal equipment is obtained by acquiring the coordinate information generated by the terminal equipment and generating the mode of combining the pressure information at the touch pen end, and the coordinate information for determining the touch pen to touch the display interface of the terminal equipment is not required to be added into the coding signal through the touch pen, so that the writing handwriting of the touch pen displayed on the display interface of the terminal equipment by a user is truly reflected, and the experience of the user is improved.
Further, the application provides still another embodiment of the display method of the handwriting of the touch pen.
The difference between the second embodiment of the display method of the handwriting of the touch pen and the first embodiment of the display method of the handwriting of the touch pen is that the obtaining of the coordinate information of the touch position when the touch pen touches the terminal device comprises:
step S31, acquiring first time information carried by the coded signal, wherein the first time information is time information counted by a first timer of the touch pen when a pen point of the touch pen touches the terminal device;
step S32, acquiring second time information counted by a second timer of the terminal device when the pen point of the touch pen touches the terminal device, wherein the second time information and the position information are stored in a mapping manner;
in step S33, when the second time information is equal to the first time information, it is determined that the coordinate information of the second time information is the coordinate information corresponding to the pressure value of the first time information.
In this embodiment, when the terminal device receives the coding signal, the pressure value when the user uses the touch pen is obtained according to the obtained coding signal, and then the handwriting corresponding to the pressure value is redrawn at the corresponding position.
In this embodiment, because the pressure information is encoded on the touch pen to form an encoded signal, which is sent to the terminal device, when the terminal device receives the encoded signal, it needs to be determined that the currently received encoded signal sent from the touch pen matches the coordinate information obtained in the terminal device, so as to obtain the handwriting of the touch pen on the display interface of the terminal device.
Specifically, the step S30 of the first embodiment is carried out, when the pad receives the coded signal, a decoding operation is performed on the coded signal to obtain a corresponding pressure value of 1.5N, and then the coordinate information of the current identifier 1 is obtained and determined as the target coordinate information corresponding to the pressure value, and then the target coordinate information is determined to be the coordinate information of the touch position when the touch pen touches the display interface of the terminal device. And further displaying the 1.5N handwriting in the display interface.
Further, in the present application, the pressure information may be obtained by a pressure sensor disposed inside the stylus pen. Furthermore, a sensor for monitoring whether the gravity condition of the touch pen changes, such as a gravity sensor, can be installed in the touch pen. And when the position of the touch pen is monitored to be changed, starting the pressure sensor to enter a working state so as to quickly acquire pressure information when a user uses the touch pen to write, and forming writing handwriting. When the touch pen is detected to be in the horizontal state, the pressure sensor is controlled to enter the dormant state, so that energy consumption is saved.
In the present embodiment, a timer is attached to the touch pen to count the pressure data acquired by the pressure sensor. When the pressure information exists on the touch pen, counting first time information of the obtained pressure, and coding the first time information together to form a coding signal and sending the coding signal to the terminal equipment when the pressure information is coded.
It can be understood that, in the application, when the touch pen is used for acting on the display interface of the terminal device, when the touch pen detects that pressure data (a user uses the touch pen to write), a position where the touch pen touches the display interface is generated in the display terminal at the same time, based on the coordinate system established in the previous embodiment, coordinate information of the position is obtained, second time information when the touch pen touches the display interface is counted by using a second timer, and the coordinate information and the second time information are mapped and stored in the preset memory, so that the coordinate information at different times can be quickly obtained.
When the terminal equipment receives the coded signal, decoding operation is carried out on the coded signal, so that first time information and a pressure value are obtained, the first time information and the pressure value are compared with second time information, and when the first time is equal to the second time, the obtained pressure value is determined to be matched with the coordinate information. The accuracy of pressure value and coordinate information matching is improved.
Further, referring to fig. 4, another embodiment of the display method of the writing handwriting of the touch pen of the present application is proposed.
The third embodiment of the display method of the handwriting of the touch pen is different from the first embodiment and the second embodiment of the display method of the handwriting of the touch pen in that after the step of acquiring the second time information counted by the second timer of the terminal device when the pen tip of the touch pen touches the terminal device, the method comprises the following steps:
step S224, acquiring first time information counted by the first timer and second time information counted by the second timer at the current moment in real time;
step S225, comparing the first time information with the second time information;
step S226, when the first time information is not equal to the second time information, calibrating the first time information and the second time information to make the first time information equal to the second time information.
In the application, the terminal device obtains the first time information counted by the first timer in real time, and compares the first time information with the time information of the second timer. If the first time information is not equal to the second time information, calibrating the first time information and the second time information to make the first time information equal to the second time information, specifically, adjusting the first timer alone, or adjusting the second timer, or adjusting the first timer and the second timer simultaneously.
In this embodiment, by calibrating that the first time information of the first timer is equal to the second time information of the second timer, the accuracy of matching the pressure value with the coordinate information is improved.
After the step of obtaining the first time information counted by the first timer and the second time information counted by the second timer at the current moment in real time, the method further includes:
step S227, when the first time information is equal to the second time information, determining whether to enter a next period;
in step S228, when the next period is entered, the first timer and the second timer are controlled to restart timing.
In the application, the first timer and the second timer are periodically counted, whether the next period is entered is judged, the period is that the first timer and the second timer start counting from the current time, after the preset time is reached, the current counted time is cleared, and the counting is restarted. Specifically, the preset time may be set to 300 seconds, and within 300 seconds, when a touch pen touches a display interface of the terminal device, first time information acquired by the first timer is 1 second 04 milliseconds, second information counted by the second timer is 1 second 04 milliseconds, and the first time information is equal to the second time information, the corresponding pressure value and the coordinate information are matched, and a writing trace of the touch pen continuously acquires a coding signal sent by the touch pen, decodes the coding signal, and matches the coding signal with the coordinate information stored in the terminal device. And at the 300s, acquiring that the first time information is 300s by decoding the coded signal, displaying the handwriting on a display interface after the pressure value obtained by decoding is successfully matched with the coordinate information, sending an instruction for clearing the time counted by the first timer to the touch pen and entering the next period, and controlling the second timer to enter the next period when the first timer enters the next period. By enabling the first time information counted by the first timer to be equal to the second time information counted by the second timer, when the time information is used for matching, the accuracy of matching the coordinate information and the pressure value is improved.
Further, based on the previous embodiment, the application provides another embodiment of the display method of the handwriting of the touch pen.
The fourth embodiment of the method for displaying handwriting of the touch pen is different from the first, second and third embodiments of the method for displaying handwriting of the touch pen in that the step of combining the coded signal and the coordinate information to obtain the handwriting of the touch pen and displaying the handwriting on the display interface of the terminal device includes:
and step S40, when the code signal is acquired again from the coordinate information, adjusting the writing handwriting of the touch pen according to the code signal.
In the application, when the coded signals are acquired twice in the same coordinate, it is confirmed that a user needs to adjust the writing handwriting at the position, the decoded pressure value of the coded signal acquired for the first time is compared with the decoded pressure value of the coded signal acquired for the second time, and when the first pressure value is larger than or equal to the second pressure value, the handwriting is controlled to be unchanged; when the first pressure value is smaller than the second pressure value, the handwriting in the coordinate information is adjusted by the second pressure value, and the quick adjustment of the handwriting is realized.
In this embodiment, after displaying the handwriting, before the step of adjusting the handwriting of the touch pen according to the encoded signal in the same place is received, the method includes:
step S01, decoding the re-acquired coded signal to obtain first time information and a pressure value of the coded signal;
step S02, obtaining coordinate information corresponding to the pressure value according to the first time information;
and step S03, when the coordinate information has executed the matching operation, executing the step of adjusting the writing handwriting of the touch pen according to the coding signal.
When the coded signal is obtained, decoding operation is performed on the coded signal, first time information and a pressure value are obtained, then coordinate information corresponding to the pressure value is obtained through the first time information, when the coordinate information is determined to be matched, the coded signal is determined to be the coded signal for adjusting the handwriting of the touch pen, adjustment operation is performed on the handwriting at the position, the handwriting thickness of a user at the position displayed on a display interface of the terminal device can be drawn in real time, and the use feeling of the user is improved.
