Description

Method for transmitting and receiving instant communication based on handwritten original handwriting and terminal

Technical field

The present invention relates to the field of communications, and in particular, to a method for transmitting and receiving instant messaging based on handwritten original handwriting and a corresponding communication terminal.

Background technique

Instant messaging, IM (Instant Messaging) is a way to exchange real-time messages through relevant communication application software on communication terminals, such as QQ, Fetion, Taobao Want, MSN, etc. Instant messaging has great advantages compared with ordinary mail, mainly It makes communication communication faster and more instant, similar to face-to-face instant communication. However, in the existing instant messaging technology, message communication is presented on the user communication terminal in the form of a computer standard word.

With the development of handwritten original handwriting, handwritten original handwriting mail, handwritten original handwriting notepad software, handwritten annotations, etc. have begun to be applied. Since the user is accustomed to writing with a pen, the original handwriting can be completely retained by using an electromagnetic pen. Handwriting input handwriting, writing smooth and natural, more in line with the user's habits, for the user, handwriting input for meeting records, handwritten mail, signing documents, handwriting Internet access, etc. will be very convenient.

Therefore, there is an urgent need for an instant communication method and terminal based on handwritten original handwriting, and the existing instant communication method based on handwritten original handwriting first converts the generated handwritten original handwriting text into a picture, and then transmits the generated picture. Identify and display the recipient. Since the amount of data transmitted in the format of the picture is large and the resources occupied are large, there is a certain requirement on the bandwidth. If the bandwidth cannot satisfy the instant transmission of the data, the delay time of the picture message sent by the receiver after receiving the picture is received by the receiver. Longer, even after receiving the picture message sent by the sender, it cannot be recognized and opened, so that the purpose of instant communication cannot be achieved, and the user experience is greatly reduced.

Therefore, a new instant communication method based on handwritten original handwriting is urgently needed to ensure that the handwritten original handwriting message sent by the sender can be presented in front of the user in an instant and complete manner, so that both users can truly experience the writing process of the handwritten original handwriting. It feels like writing communication face to face, Increased intimacy.

technical problem

An aspect of the present application provides a method of transmitting instant messaging based on handwritten original handwriting.

Technical solution

An aspect of the present application provides a method for transmitting instant messaging based on handwritten original handwriting, including: determining a start of a round of sampling; sampling a sample point representing an original handwriting on an input interface according to a set sampling frequency, and acquiring the sampling The coordinate information of the point and the information indicating the sampling time relationship of each sampling point; determining the end of one round of sampling, transmitting the coordinate information of the sampling point acquired by the current round sampling and the information indicating the sampling time relationship of each sampling point to the receiving side.

The beneficial effects of the present application are: the sender communication terminal in the present application sends the coordinate information of each sampling point and the information indicating the sampling time relationship of each sampling point to the receiving communication terminal, and is not a picture, and the amount of data transmitted is small. The occupied communication resource is short; the receiving communication terminal immediately receives the coordinate information of each sampling point sent by the transmitting communication terminal and the information indicating the sampling time relationship of each sampling point, and then according to the information indicating the sampling time relationship of each sampling point. Each sampling point is correspondingly restored and displayed according to the coordinate information of each sampling point, so that the writing process of the sending communication terminal can be completely and instantaneously reproduced in the receiving communication terminal, that is, the transmitting communication terminal Write a stroke, the receiving communication terminal can basically receive and reproduce the writing process of this stroke, which greatly improves the user experience.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the invention

Aiming at the existing handwritten original handwriting-based instant communication, the amount of picture data is large, and the resources occupied are large, and the delay time of transmission and display is long, especially in the case of small bandwidth, the transmitted picture information cannot be transmitted in time. However, the present invention provides a new instant communication method based on handwritten original handwriting, and the sender communication terminal acquires handwriting features of each sampling point of the sampling point group, even if the display cannot achieve the purpose of instant writing original handwriting communication. And information indicating the sampling time relationship of each sampling point of the sampling point group, and immediately transmitted to the receiving communication terminal, the transmitting communication terminal is not transmitting data in the picture format, so the amount of data sent is small, and the occupied resources are small, subject to The impact of bandwidth is small and the applicability is wider. Since the transmitting communication terminal is sent in units of sampling point groups, and the receiving communication terminal sequentially restores and displays the corresponding sampling points according to the sampling time relationship of each sampling point, the user of the receiving communication terminal can see the user of the transmitting communication terminal. The writing process improves the user's experience while improving the immediacy of communication.

The present application will be further described in detail below with reference to the accompanying drawings.

The sender communication terminal and the receiver communication terminal in this example may be a mobile phone with a handwriting function, a computer, a handwritten tablet, or other communication device externally or integrated with a handwriting input device.

The stroke in this example refers to a stroke written by a user from a pen point to a pen point when writing, and is not a standard stroke in which a Chinese character is split into a single stroke in a strict sense. For example, when the user writes in a stroke of a Chinese character instead of a continuous stroke, the stroke in this example is equivalent to a standard single stroke. When the user writes continuously, the user may write a few standard single strokes or even a stroke. A word, these standard single strokes or the word is a stroke in this example, a pen point and a pen point determine a stroke.

In this example, the sender communication terminal and the receiver communication terminal may be unidirectional, that is, the sender communication terminal can only send a message, and the receiver communication terminal only receives the message; or may be bidirectional, that is, the sender communication terminal is When receiving the message of the other party, it is the receiving party communication terminal. Correspondingly, at this time, the receiving side communication terminal of the transmitting message is the transmitting side communication terminal, that is, the transmitting side communication terminal and the receiving side communication terminal both have receiving and transmitting the handwritten original handwriting message. Features. For example, the communication terminal A is transmitting a message a to the communication terminal B, and the communication terminal B is simultaneously transmitting the message b to the communication terminal A. At this time, the communication terminal A is receiving the message b, and the communication terminal A is the receiving communication terminal with respect to the message b. The communication terminal B is the sender communication terminal with respect to the message b. Similarly, the communication terminal B receives the message a at the moment, the communication terminal B is the receiver communication terminal with respect to the message a, and the communication terminal A is the sender with respect to the message a. Communication terminal. The sender communication terminal and the receiver communication terminal in this example are bidirectional.

In this example, the sampling frequency of the sender communication terminal and the receiver communication terminal may be set to the same sampling time interval, or may be set to different sampling time intervals, or the default sampling time of the transmitting communication terminal and the receiving communication terminal itself. Interval, if one of the parties does not need to send a message to receive only the message, the communication terminal at the end does not need to set the sampling frequency. The specific sampling frequency can be set according to the actual situation.

Referring to FIG. 1, in this example, when the two-party communication terminal based on the handwritten original handwriting performs instant communication, the following steps are included:

The transmitting communication terminal determines to start a round of sampling, and samples a sampling point representing the handwritten original handwriting on the input interface according to the set sampling frequency to obtain a sampling point group, and obtains handwriting features (such as coordinate information of each sampling point in the sampling point group). And information indicating the sampling time relationship of each sampling point in the sampling point group, and after determining the end of one round of sampling, the handwriting characteristics of each sampling point in the sampling point group and the sampling of each sampling point in the sampling point group The time relationship information is sent to the receiving communication terminal;

The receiving communication terminal sequentially displays the original handwriting corresponding to the handwriting feature of the sampling point on the display interface according to the received information indicating the sampling time relationship of each sampling point in the sampling point group, for example, sequentially extracting each of the sampling point groups. The handwriting features of the sample points are displayed accordingly.

In this example, the information indicating the sampling time relationship of each sampling point in the sampling point group may be the sampling frequency of the transmitting communication terminal (corresponding to the sampling time interval between two adjacent sampling points, and the system samples according to each sampling point. The sequence is packaged and sent, and the sampling points are sequentially displayed according to the time difference of adjacent sampling points during decompression display, or the absolute time or relative time of the transmitting communication terminal. In this example, the absolute time refers to the sender. The system time when the communication terminal samples the stroke, and the relative time refers to the time defined by the first sampling point as the starting point. For example, the sampling frequency is set to be sampled once per second, and the time of the first sampling point is set. For 0 seconds, the second sample point is 1 second, the third sample point is 2 seconds, and so on. After receiving the information indicating the sampling time relationship of each sampling point in the sampling point group, the receiving communication terminal can know the sampling order of each sampling point at the transmitting communication terminal and the display order of each sampling point locally.

It is worth noting that the sampling point group of the handwritten original handwriting in this example (that is, the set of sampling points obtained by one round of sampling) has multiple division manners according to the actual situation, such as a sampling point for determining a stroke. The point group may also be a sampling point group within a preset time period, and the sampling point in the time period may determine one stroke or several strokes, or several characters or a piece of text, or even just determine one Part of the stroke, therefore, the instant communication method provided by the present application does not have to wait for a word or a message to be packaged and sent together, which can further reduce the amount of data and resource usage per transmission, and improve the immediacy of communication. More applicability. The following is a further description of the application in several preferred ways:

Method 1: Determine all the sampling points of a stroke as a sampling point group, that is, a sampling point group determines a stroke, and the strokes in this example have been clearly stated above. At this time, the transmitting communication terminal sends the handwritten original handwriting to the receiving communication terminal in units of strokes. After receiving the sampling point group, the receiving communication terminal also displays correspondingly according to the sampling time relationship of each sampling point in the sampling point group. Strokes. Therefore, the strokes received by the receiving communication terminal are complete, and the implementation means is simple and easy. However, in some special cases, when the sender communication terminal writes a stroke for a long time (such as several words to write), the receiver communication terminal can only be in the period of writing by the sender communication terminal. If the selection waits, the sender communication terminal and the receiver communication terminal have no information exchange during this period, which delays the immediacy of the communication to some extent. Because the immediacy required by the present application means that the sender communication terminal writes a stroke here, the receiver communication terminal can basically reproduce the stroke immediately, and the waiting delay time in the middle is as small as possible.

Manner 2: In order to prevent the occurrence of the special situation in the foregoing mode 1, in the process of handwriting by the sender communication terminal, the transmission frequency of the transmission sample group can also be set, for example, it can be set to be sent every 1 second, that is, A sample point group is the point sampled during the sampling time of 1 second. The specific implementation is as follows: the process of determining a sampling point group may be referred to as one round sampling, and the sampling point within a period of time from a round of sampling to a preset time threshold is a sampling point group, correspondingly, in this example The time threshold can be 1 second. The sampling point obtained from one round of sampling to the sampling time of 1 second is a sampling point group, which is sent to the receiving communication terminal for instant display.

The sampling points in the sampling point group in the second mode can determine one stroke or several strokes according to the time threshold setting, and even determine several characters or a piece of text (when the time threshold is large), so the flexibility is more Well, the settings can be specifically selected according to the user's writing speed and sampling frequency, and there is no problem that may exist in the first method. However, in some cases, if the stroke determined by each sampling point of the sampling point group is not a complete stroke or a complete stroke within a fixed time threshold, the receiving end receives the displayed stroke. Complete strokes. If a slight error (such as packet loss, out-of-order, etc.) occurs during the transmission of the sampling point group, subsequent sampling points may not be displayed next to the previous sampling point or may not be displayed in order. Subsequent processing and display and identification are inconvenient.

Manner 3: In order to avoid the problems in the special case in the first mode and the second mode, and improve the stability and reliability of the instant communication, the maximum time threshold and the minimum time threshold may be set for the sampling time, and one sample may be determined. The process of the point group is called a round of sampling. At this time, the sampling point group is divided into: determining whether a pen up point occurs before reaching the set minimum time threshold, and if so, determining to end the round sampling when the minimum time threshold is reached. If not, it is judged whether the pen up point occurs before the set maximum time threshold is reached. If it occurs, it is determined that the end of the round up sampling occurs when the pen up point occurs, and if not, the end is determined when the maximum time threshold is reached. One round of sampling, for example:

After the start of one round of sampling, if the pen up point does not appear when the sampling time reaches the minimum time threshold, and the penning point does not appear when the sampling time reaches the maximum time threshold, the sampling is determined during the period from the sampling start to the maximum time threshold. Point is a sample point group;

After the start of one round of sampling, if the sampling time reaches the minimum time threshold and the pen up point occurs when the maximum time threshold is not reached, the sampling point in the sampling time from the start of sampling to the time when the pen up point occurs is determined as a sampling point group;

After a round of sampling starts, if the pen up point occurs when the sampling time does not reach the minimum time threshold, and the pen point does not appear when the minimum time threshold is reached, the sampling point in the sampling time from the start of sampling to the minimum time threshold is determined to be one. Sample point group.

For example, in this example, the minimum time threshold can be set to 0.5 seconds, and the maximum time threshold can be set to 3 seconds. In the course of one round of sampling, if the pen up point is detected within a time period of less than 0.5 seconds, then The sampling time is to continue detecting whether there is a new pen down point when the minimum threshold is reached for 0.5 seconds. If not, the sampling point in the sampling time when the sampling starts to the minimum time threshold of 0.5 seconds is determined as a sampling point group, and the new next step is continued. Round sampling, avoiding the waiting for a long time; if there is, continue to count, sample, if the sampling time does not reach 3 seconds but has exceeded the 0.5 second when the pen up point occurs, then this round of sampling ends, in the sampling The sampling point in the time period is a sampling point group, and the new next round sampling is continued; if the sampling time has reached 3 seconds but the lifting point has not yet appeared, the sampling point from the beginning of the sampling to the 3 seconds is one. Group the sample points and continue with a new round of sampling. Generally, according to the writing speed of the user and the sampling frequency of the communication terminal, there is little occurrence of the pen up point from the start of sampling to the maximum threshold, and there is substantially no such, therefore, the stroke determined by each sampling point of the sampling point group at this time All are complete strokes, which are less affected by network quality, better immediacy and versatility. In this example, the selection method is divided into three groups of sampling points.

In this example, the handwriting features of each sampling point in the sampling point group include the coordinates of the sampling point and the pressure value. After receiving the handwriting features of each sampling point in the sampling point group, the receiving communication terminal displays the sampling point group according to the time relationship of each sampling point according to the handwriting characteristics of each sampling point. The details are as follows: according to the coordinates of each sampling point, the display position of each sampling point can be obtained, and the display pen width of the sampling point can be obtained according to the pressure value of each sampling point (each pressure value can also be set to a unique pen width) At this time, the obtained text has only one pen width, and the pen is not displayed. According to the sampling time relationship of each sampling point, the display order of the corresponding sampling points can be known.

Therefore, in this example, the transmitting communication terminal can send a message to the receiving communication terminal in a unit of sampling point group, and the handwriting feature of each sampling point of the sampling point group and the sampling points of the sampling point group are known from above. The data amount of the sampling time relationship information is much smaller than the number of image formats, so the occupied resources are small, the bandwidth requirement is small, and the applicable range is wider. Receiving, by the receiving communication terminal, the handwriting feature of each sampling point in the sampling point group sent by the transmitting communication terminal and the sampling time relationship of each sampling point of the sampling point group, according to each sampling point characterizing the sampling point group The information of the sampling time relationship sequentially extracts the handwriting features of each sampling point, and sequentially restores the corresponding sampling points in the corresponding positions according to the sampling time relationship of each sampling point of the sampling point group, thereby displaying the corresponding handwritten original handwriting, thus The user of the receiving communication terminal can see the writing process of the user of the transmitting communication terminal, and the user of the receiving communication terminal can also reply immediately at the same time as the writing of the sending communication terminal user, and bring the user to write in person. The experience of communication allows users of both communication terminals to truly experience the writing process of handwritten original handwriting, which increases the intimacy.

In order to make the text written by the user show the same effect as the text written on the traditional paper to further improve the user experience, the handwriting features of each sampling point in this example also include the type of the pen tip displayed and the pressure value corresponding to the sampling point. The pen width, the corresponding relationship between the pressure value and the pen width can be set in advance, and the correspondence between the pen width and the pen type can also be set in advance. The type of the pen can be selected as a pen, a brush, etc., or it can be set to the default display mode without a pen effect. At this time, the pen width of each sampling point can be set to a uniform value. For example, if the receiving communication terminal can be selected as the brush type, the pen width corresponding to the corresponding pressure value is the pen width of the brush type, and the displayed pen edge effect is also the pen edge effect written by the brush, and the sender communication terminal can be set to For the pen type, the pen width corresponding to the corresponding pressure value is the pen width of the pen type, and the pen effect displayed is also the pen effect of the pen writing.

In this example, in order to further meet the user's individual needs, the handwriting features of each sampling point may also include display colors, and the specific display colors may also be selected by the user, for example, the previous or several strokes or sampling points may be set. Displayed in red, the following strokes or sampling points are set to black, etc., or the adjacent text or adjacent paragraphs of text are set to different colors, or the sent messages are all set to a color or system default s color.

In this example, the sample point features such as display color, display type and pen width can also be sent to the receiving communication terminal as the attribute data packet of the original handwriting, or the handwriting characteristics of each sampling point in the sending sample point group. And sending the sampling time relationship information of each sampling point in the sampling point group to the receiving communication terminal, and after receiving the attribute data packet, the receiving communication terminal can set the display color of the sampling point group according to the attribute data packet, The type of stroke displayed, etc. If the attribute data packet of the original handwriting (such as display color, display stroke type, and pen width information) is previously transmitted to the receiving communication terminal, the transmitting communication terminal does not have to transmit the handwriting features of each sampling point in the sampling point group. Each time, the sampling point features such as display color, display type and pen width are sent, thereby further reducing the amount of data sent and speeding up the processing speed of the system.

In addition, when the handwritten original handwriting is used for instant communication communication, since the sender communication terminal and the receiver communication terminal may simultaneously write characters at the same position of the communication terminal display interface, the sender communication terminal and the receiver communication terminal simultaneously transmit at the same time. Messages may appear to overlap at the same location on the local display interface, causing messages sent and received to be unclear. Therefore, in this example, the receiving communication terminal can also adjust the display position of the strokes represented by the sampling points in the received sampling point group, and the receiving communication terminal receives the handwriting features of each sampling point in the sampling point group and represents the sampling point. After the information about the sampling time relationship of each sampling point of the group, it is determined whether the display position of the stroke represented by each sampling point in the sampling point group on the local display interface conflicts with the position of the existing existing stroke (for example, overlap), if The receiving communication terminal adjusts the display position of the strokes represented by the sampling points in the sampling point group according to actual conditions, and the adjustment manner may be uniformly adding or offsetting the coordinates of each sampling point, so that the corresponding strokes are displayed locally. There is no position display of the stroke on the interface, so as to avoid overlapping of the received stroke with the existing stroke.

In addition, the receiver can also adjust the position, size, and the like of the content to be displayed according to other factors, for example, panning, zooming, and the like of the content to be displayed. For example, the receiving party can determine the display position of the content to be displayed on the screen according to the set margin (for example, the distance between the actual display area and the left end, the top end, the right end, and the bottom end of the display interface), and the set margin Differently, the displayed position will also change accordingly. For example, the receiver can scale the height, width, etc. of the text to be displayed according to the set zoom ratio (or determine the corresponding display scale according to the size of the content to be displayed). Adjustment. The specific display processing method adopted by the receiver does not constitute a limitation on the present embodiment.

Therefore, in this example, the text displayed by the instant communication method based on the original handwriting is not only immediate, complete, and has no lag, but also has the same smooth stroke as the traditional written text on the paper, further improving the user experience. . In addition, the receiving communication terminal in this example can also adjust the display position of the strokes represented by the sampling points in the received sampling point group on the local display interface according to actual conditions, and avoid the sending by the transmitting communication terminal and the receiving communication terminal. The messages overlap and the design is more user-friendly.
