When speaker interacts with audience in the related technology, electronics of the written contents in audience of speaker cannot achieve Real-time display in equipment, affects the interaction effect of speaker and audience, and user experience is not high.

To solve the above-mentioned problems, the disclosure provides a kind of handwriting trace display methods and device, passes through real-time detection The writing of one terminal operates, and while obtaining corresponding written information by the written information of acquisition be sent to other terminals into Row display realizes simultaneous display of the handwriting trace from first terminal on the display screen of other terminals, facilitates use The use at family, improves user experience.

Fig. 1 is a kind of flow chart of handwriting trace display methods shown according to an exemplary embodiment, as shown in Figure 1, The handwriting trace display methods is applied in first terminal, includes the following steps 101-103:

In a step 101, operation is write in detection.

Here, first terminal can be the portable electronic device that mobile phone, tablet computer etc. have Touch Screen, can also be with It is equipped with other electronic equipments of Touch Screen, such as the desktop computer etc. equipped with Touch Screen；It can also be and be arranged The electronic pen write on the medium (for example, the paper for being printed with sightless lattice coordinates code) for having dot matrix.Here, when When one terminal is the electronic equipment with the first screen, first terminal can be the case where application-specific or function be opened Under, the writing operation on the first screen is detected, for example, when note function or painting function or drawing board application on first terminal When program is opened, show that user at this time needs to carry out the input of text or figure on the first screen, first terminal can be at this time The writing operation on the first screen is detected, to improve detection efficiency, mitigates the operation burden of the processor of first terminal；Alternatively, First terminal can also persistently detect the operation of the writing on the first screen according to preset frequency, for example, with the frequency of interval 1ms It is detected, the embodiment of the present disclosure is not specifically limited herein.

Here, the first screen can be resistance type touch control screen, electromagnetic induction touch screen, infrared-type touch screen, capacitor sense Answer formula touch screen or surface acoustic wave type touch screen, first terminal can be by pressure on the first screen of detection, the first screen The changes of magnetic field of inductor, variation of infrared light etc. detects on the first screen with the presence or absence of writing behaviour on the first screen Make.It is exemplary, it is corresponding on the first screen when time writer is close to the first screen when the first screen is electromagnetic induction touch screen Partial magnetic flux can change, and therefore, the variation by detecting magnetic flux on induction touch screen can be realized pair The detection of writing operation on first screen.Here, when first terminal is electronic pen, built-in high speed video camera can be passed through Detection is provided on the medium of dot matrix with the presence or absence of handwriting trace, is come with this it is judged whether or not writing operation.

In a step 102, the written information for writing operation is obtained, and with the data format of Bit Oriented type to written information It is encoded, obtains writing data, written information includes writing point corresponding to the time of origin point and time of origin point of operation Coordinate.

In step 103, the writing data obtained in the first preset time period are sent to second terminal, so that second is whole End shows the handwriting trace write and operated according to data are write on the screen.

Here, when first terminal is the electronic equipment with the first screen, the written information includes the writing behaviour Make the display area of first screen corresponding to the time of origin point and the time of origin point on first screen Pixel coordinate.First terminal can the pixel coordinate of each point changed to magnetic flux on the first screen and each The time of the corresponding magnetic flux change of point is obtained, alternatively, can each pixel changed to pressure on touch screen The pressure changed time corresponding to the coordinate and each pixel of point obtains etc., submits a written statement to a higher authority to obtain the first screen The corresponding written information of write operation.Here, first terminal shows that the writing is believed after obtaining written information on the first screen While handwriting trace corresponding to breath, the written information is sent to second terminal.In another embodiment, written information is also It may include the pressure value of each pixel, first terminal and second terminal can be according to the pressure values of each pixel to picture Vegetarian refreshments is cooked vigour of style in writing effect process, the pixel coordinate that obtains that treated, to pass through treated the picture of display on the first screen The coordinate of vegetarian refreshments comes so that handwriting trace has the effect of the writing brush vigour of style in writing.For example, when the pressure for the pixel for detecting the first quantity When force value is less than preset value, the partial pixel point adjacent with those pixels can be counted in the pixel of handwriting trace, be made Those pixels be formed by handwriting trace line thickness it is thinner；When the pressure value for the pixel for detecting the second quantity is big When preset value, all pixels point adjacent with those pixels can be counted in the pixel of handwriting trace, so that The line thickness that those pixels are formed by handwriting trace is wider, to show on the first screen and the second screen with this Handwriting trace has the effect of the writing brush vigour of style in writing.In this way, can be to avoid in the related technology, speaker is in the speaker's equipment itself used On explanation content write or after being labeled to the specific content shown in speaker's equipment, need by triggering electronics Correlation function in equipment will could perhaps mark the electronic equipment for being stored and being sent to other audiences in the explanation of writing Upper display, and caused by operated for speaker it is not easy and for audience because explanation in perhaps mark transmission it is too late When and the problem of influence the understanding to content, realize the handwriting trace from first terminal on the display screen of other terminals Simultaneous display simplifies operating procedure when first terminal is interacted with other terminals, while improving and interacting between multiple terminals Timeliness.

When first terminal is electronic pen, can be moved through by high speed video camera with preset high frequency scan pen tip The point that each moment is covered in journey obtains multiple coordinates and corresponding time point by built-in processor accordingly, to make For the written information of first terminal, and then written information is encoded into writing data, is sent to second terminal and is shown.Such as This, written contents could be edited and to listening by avoiding speaker in the related technology and needing to rely on speaker's equipment with display screen Crowd shows, and causes the problem of victory inconvenient for use so that speaker can without using with the terminal for showing screen, The handwriting trace simultaneous display that terminal is generated facilitates the operation of user, improves user's body on the electronic equipment of audience It tests.

Here, due to usually being transmitted in the form of bit stream when data are transmitted in the related technology, first terminal exists Before the information of acquisition is transmitted to second terminal, compiled using the information that the data format of Bit Oriented type transmits needs Code avoids carrying out data lattice again when data are transmitted in this way, can be convenient the transmission of data between first terminal and second terminal The conversion of formula；In addition, for character-oriented type data format, data format using Bit Oriented type is to needing to transmit Data encoded, the data after can also making coding are carried out continuously transmissions, and efficiency of transmission is high, and transmit it is transparent good.

In the present embodiment, it can be needed come common definition first terminal to second by movement with two fields of action data The data of terminal transmission, wherein movement field can be defined and account for a byte, and the size of byte shared by action data field is not It is fixed, it can be determined according to specific action data, wherein between each state value of movement field and the meaning of each state value Corresponding relationship indicates the classification of action data by the state value as shown in the table 1 of lower section.

Table 1

For example, Fig. 2 is the data format schematic diagram shown according to an exemplary embodiment for writing data, as shown in Fig. 2, When first terminal needs encode the point coordinate of acquisition and corresponding time point, writings data packet include act, Three fields of coordinate and state, coordinate field and status bar position form action data field, wherein the state value for acting field is "3".Movement field and state field respectively account for a byte, and coordinate field accounts for four bytes, which respectively indicates the number According to the X, Y coordinates value for coordinate data, point, and the state of point.Here it is possible to set state field there are two state value " 0 ", " 1 " is corresponded with " paintbrush suspension point " state of point, " paintbrush transfer point " state respectively.Here, when the state of point is " to draw When suspension point ", the end of a stroke in handwriting trace is indicated, indicate that the point is when the state of point is " paintbrush transfer point " Write the stylus of operation generated point when moving on the first screen, or is electronic pen in Jie for being provided with dot matrix Generated point when being moved in matter.Exemplary, time point corresponding to each coordinate can be by each in written information The sequencing of the coding of coordinate is put to embody, for example, time point corresponding to point (X11, Y11) is T11, point (X22, Y22) Corresponding time point be T22, and T11 be less than T22, then first point (X11, Y11) can be encoded, then to point (X22, Y22 it) is encoded, in this way, the time corresponding to each coordinate is embodied by the sequencing encoded, so that in first terminal When persistently being encoded to the written information of acquisition, and continuing the writing data packet after coding being sent to second terminal, the Two terminals are successively decoded each writing data packet according to the sequencing of each writing data packet received, obtain The coordinate of corresponding point, so that according to the sequencing for obtaining point coordinate, the handwriting trace of operation is write in display.

Here, first terminal just encodes written information when getting written information, and coding just will after completing The writing data that coding obtains are sent to the display that second terminal carries out handwriting trace, avoid mistake of the user on first terminal Multioperation simplifies user when first terminal is interacted with second terminal and needs the step of operating.Exemplary, first terminal can Data are write so as to be every 100ms send to second terminal.

Here, first terminal and second terminal can be two terminals in the same local area network, be also possible to lead to Cross two terminals that connection relationship has been established in the other modes such as bluetooth.Second terminal can be mobile phone, tablet computer etc. with touching The portable electronic device for controlling screen is also possible to other electronic equipments equipped with Touch Screen, such as aobvious equipped with touch-control The desktop computer etc. of display screen curtain, with receive first terminal transmission writing data when, according to the writing data itself It shows handwriting trace corresponding to the simultaneous display writing data on screen, improves the timeliness interacted between terminal.
