With the development of science and technology, the way of inputting information by touch has gradually replaced the traditional way of writing information on the blackboard using chalk and markers, and has been integrated with the way of inputting information on the pinyin keyboard. It provides convenience for people both in work and in life. For example, mobile phones, tablets, video playback terminals and other devices used in people's lives can not only input text information through the pinyin keyboard, but also directly write text on the screen through fingers or electromagnetic stylus and display it directly on the device screen; For another example, a separate input device (such as a handwriting tablet) is connected to a control device (such as a personal computer PC), and the control device is connected to the display terminal, and the user inputs information in the writing area of the handwriting tablet by means of touch input. The control device acquires and processes the input information and sends it to the display terminal for display, which also provides convenience for people who are not good at using the keyboard.

In the related art, a capacitively coupled touch array and/or an electromagnetic induction array are arranged in the writing area of the input device; the user can touch the input device by means of capacitive induction through finger touch or electromagnetic induction by touch with an electromagnetic stylus pen.

For example, when multiple people participate in a conference, each person needs to be equipped with an input device, each input device is connected to a control device, and each control device is connected to a display terminal, so that the information written by all participants can be simultaneously Therefore, if the number of people participating in the meeting is large, it needs to be equipped with a large number of input devices, control devices and displays, which is very inconvenient.

Since the valid information includes the position information of the electromagnetic signal of at least one induction frequency generated when the user writes in the plurality of sub-writing areas, the position of the electromagnetic signal is determined based on the different induction frequencies. The information can be differentiated, and the corresponding input trajectories of electromagnetic signals with different induction frequencies can be generated; and, based on the type of the induction signal, the position information corresponding to the capacitive signal and the electromagnetic signal can be distinguished to obtain the corresponding input trajectories of the different types of induction signals. ; thus realizing that multiple people input information in their respective sub-writing areas without interfering with each other, solving the defect that only one touch sensing signal can be recognized in the traditional touch input method, and realizing that one input device supports multiple people using multiple electromagnetic The technical effect of simultaneously inputting information in multiple sub-writing areas with the stylus pen improves the convenience during use.

, determine the number of people who can sit around the conference table according to the size of the entire desktop, and then set the number of sub-writing areas to the number of people who can sit around, and determine the positions of several sub-writing areas on the entire desktop. If the sub-writing areas are set to a rectangle or a square , the coordinates of the four corners of a rectangle or a square can be used to indicate the position of the sub-writing area. If the sub-writing area is set as a circle, the center coordinates and radius of the circle can be used to indicate the position of the sub-writing area. For example, four sub-writing areas are set on a conference table, all of which are rectangular, and the four sub-writing areas are evenly distributed on the desktop, namely sub-writing area A, sub-writing area B, sub-writing area C and sub-writing area D, and sub-writing area A The coordinates of the four corners are marked as (

Further, you can also adjust the layout of the sub-writing area on the desktop by adjusting the coordinate values of the four corners of the sub-writing area. needs in the scenario.

It can be understood that, in order to facilitate the user to identify the sub-writing areas during use, the sub-writing areas may be marked on the desktop in advance after the number and size of the sub-writing areas are determined.

It should be noted that, in this embodiment, since the entire desktop of the conference table is provided with antenna induction arrays, when the user writes on any position on the desktop of the conference table with the electromagnetic stylus, an electromagnetic signal can be generated . Therefore, it is necessary to distinguish all electromagnetic signals generated on the desktop and the corresponding position information, and divide them into valid information and invalid information. The valid information is the information generated when the user writes in the sub-writing area, and the invalid information is the user For the information generated when writing outside the sub-writing area, the controller only processes the obtained valid information, and directly filters out the invalid information. In this way, even if the user enters information outside the sub-writing area by mistake, the writing track will not be generated. Avoid interfering with normal writing.

Further, the step of judging whether the information input by the user on the input device is valid information includes: acquiring the input position when the user inputs information on the writing area of the input device; judging whether the input position is within the Within the range covered by the multiple sub-writing areas, and when the judgment result is yes, the information of the input position is determined as valid information.

Specifically, when the user uses an electromagnetic pen to write on the desktop of the conference table, the coordinate value of the input position (that is, the coordinate value of the position where the electromagnetic signal is generated) is obtained when the information is input, and it is determined whether the coordinate value belongs to the coverage of the sub-writing area. Subset, if it is, it indicates that the generated information is valid information; otherwise, it is determined to be invalid information.

It should be noted that, in this embodiment, the conference desktop is divided into 4 sub-writing areas, but it is not limited to 4 sub-writing areas, and can also be divided into 2, 8, or even more writing areas according to actual needs, which will not be exemplified here. instruction.

In this embodiment, by utilizing the feature that electromagnetic induction can be divided into multiple writing areas, the entire writing area can be divided into multiple sub-writing areas, so that it is convenient for multiple people to use multiple pens to write in their respective sub-writing areas. interference.

In another possible embodiment, the step of dividing the entire writing area of the input device to obtain multiple sub-writing areas: sending size information of the writing area of the input device to the terminal device, where the size information is used to indicate the target A person sets a plurality of antenna induction arrays on the input device to form a plurality of sub-writing areas.

Specifically, the electromagnetic antenna induction array is not all covered on the input device, but the antenna induction array is only arranged in the set sub-writing area, and the four sub-writing areas are separated by physical isolation, so that each works independently and interacts with each other. No interference, as shown in Figure 5, is the desktop of a conference table. The desktop is divided into four sub-writing areas, and electromagnetic antenna induction arrays are arranged in the four sub-writing areas respectively, and no electromagnetic antenna induction arrays are arranged outside the sub-writing areas.

It should be noted that the plurality of sub-writing areas in this embodiment can work independently, and four sub-writing areas can also be connected in series through cables to form a large writing area.

In this embodiment, writing areas can be set on tables of various shapes, such as a ring-shaped conference table, a triangular conference table, and other polygonal conference tables, etc. The shape, style, and size of the sub-writing area can also be determined according to actual needs. set up.

FIG. 6 is a schematic flowchart of a multi-area touch input processing method according to another exemplary embodiment of the present invention. This embodiment further describes the multi-area touch input processing method on the basis of the embodiment shown in FIG. 2 in detail. .

As shown in FIG. 6 , the method provided in this embodiment may include the following steps.

In step S601, the electromagnetic signals sensed by each sub-writing area are respectively received.

Specifically, when multiple people perform writing operations in their respective sub-writing areas at the same time (as shown in Figure 3a, four pens write in the four sub-writing areas at the same time), electromagnetic signals will be induced in the multiple sub-writing areas.

For example, the first user writes in the sub-writing area A with an electromagnetic stylus, the second user writes in the sub-writing area B, the third user writes in the sub-writing area C, and the fourth user writes in the sub-writing area If you write in D, the electromagnetic signal will be generated in the four sub-writing areas at the same time.

Step S602: Determine the preset induction frequency corresponding to each sub-writing area as the frequency of the electromagnetic signal sensed by each sub-writing area, wherein different induction frequencies are respectively set for different sub-writing areas.

In this step, the induction frequency is set for each sub-writing area in advance, and different sub-writing areas are correspondingly set with different induction frequencies. After the induction frequency is set for each sub-writing area, regardless of whether the electromagnetic stylus writes in the sub-writing area The frequency of the electromagnetic signal generated at the time is determined as the frequency corresponding to the sub-writing area, so as to distinguish the writing information in each sub-writing area, and the information written in each sub-writing area does not interfere with each other.

It should be noted that the electromagnetic antenna induction array receives electromagnetic induction signals in two ways. One is the active method, that is, the electromagnetic antenna induction array is not energized, and the electromagnetic stylus has a power supply. When writing, the electromagnetic stylus runs at a certain frequency. The electromagnetic signal is emitted; the other is passive, that is, the electromagnetic antenna induction array is energized, and the electromagnetic stylus has no power supply, and the electromagnetic stylus receives and reflects electromagnetic waves when writing. In this embodiment, the electromagnetic stylus is powered.

Exemplarily, the induction frequency corresponding to the sub-writing area A is set as PA, the induction frequency corresponding to the sub-writing area B is PB, the induction frequency corresponding to the sub-writing area C is PC, and the induction frequency of the sub-writing area B is PD; When the stylus writes in the sub-writing area A, it emits an electromagnetic signal at the frequency of PE, then the frequency of the electromagnetic signal sensed by the sub-writing area A is determined as PA, not PE; similarly, the frequency of PE is used in the sub-writing area A. Inputting information in the writing area C will determine the frequency of the electromagnetic signal sensed by the sub-writing area C as PC.

In step S603, the position information corresponding to the electromagnetic signal of each frequency is obtained respectively.

Step S604 , generating different input trajectories according to the position information corresponding to the electromagnetic signals of different frequencies, and the frequencies of the electromagnetic signals and the input trajectories are in a one-to-one correspondence.

Since different induction frequencies are set for each sub-writing area in step S602, the position information corresponding to all electromagnetic signals is divided according to different frequencies, that is, each sub-writing area corresponds to the position information of electromagnetic signals of one frequency, so as to realize This ensures that the input tracks in each sub-writing area do not interfere with each other.

FIG. 7 is a schematic flowchart of a multi-area touch input processing method according to another exemplary embodiment of the present invention. This embodiment further describes the multi-area touch input processing method in detail on the basis of the embodiment shown in FIG. 6 . .

As shown in FIG. 7 , the method provided in this embodiment may include the following steps.

Step S701: Receive electromagnetic signals of different frequencies sensed by the same sub-writing area, and the electromagnetic signals of different frequencies are emitted by at least one electromagnetic stylus with different emission frequencies.

Specifically, when multiple people use the electromagnetic stylus to write in the same sub-writing area (as shown in Figure 3b, multiple electromagnetic stylus pens write in the same sub-writing area B), the sub-writing area can be closed The induction frequency set inside can adjust the emission frequency of multiple electromagnetic stylus, and the emission frequency of different electromagnetic stylus is different.

Step S702 , respectively acquiring position information corresponding to the electromagnetic signals of different frequencies sensed by the same sub-writing area.

Based on the electromagnetic signals of different frequencies emitted by the electromagnetic stylus, the position information corresponding to all the electromagnetic signals in the same sub-writing area is divided.

For example, if two electromagnetic stylus pens are writing in the sub-writing area A at the same time, then adjust the transmission frequency of the first pen to P1 and the transmission frequency of the second pen to P2, and then adjust all the electromagnetic stylus sensed in the sub-writing area A to P1. The position information corresponding to the signal is divided according to the two frequencies of P1 and P2 to obtain all the position information corresponding to the electromagnetic signal with the frequency P1 and all the position information corresponding to the electromagnetic signal with the frequency P2.

Step S703 , generating different input trajectories according to the position information corresponding to the electromagnetic signals of different frequencies, and the frequencies of the electromagnetic signals and the input trajectories are in a one-to-one correspondence.

Since different emission frequencies are set for each electromagnetic stylus in the above, the position information corresponding to all electromagnetic signals is divided according to different frequencies, that is, the position of each electromagnetic stylus corresponding to the electromagnetic signal of one frequency information, realizes the writing of multiple pens in the same sub-writing area, and the multiple pens do not interfere with each other.

FIG. 8 is a schematic flowchart of a multi-area touch input processing method according to another exemplary embodiment of the present invention. This embodiment further describes the multi-area touch input processing method in detail on the basis of the embodiment shown in FIG. 2 . .

As shown in FIG. 8 , the method provided by this embodiment may include the following steps.

Step S801: Receive a capacitance signal sensed by each sub-writing area.

It should be noted that, in addition to the electromagnetic antenna induction array, the writing area of the input device is also provided with a capacitive sensor array, so that the user can perform writing operations on the input device in a capacitive induction manner through a finger or a capacitive pen. As shown in Figures 4a and 4b, the dashed lines represent the electromagnetic antenna induction array and the dots represent the capacitive sensor array.

It can be understood that, in order to prevent the electromagnetic induction array and the capacitive sensor array from interfering with each other, the two induction arrays are arranged in isolation.

Specifically, when the user performs a writing operation on the sub-writing area of the input device through a finger or a capacitive pen (as shown in Figure 4a, four fingers simultaneously perform a writing operation in the four sub-writing areas A, B, C, and D) , each sub-writing area will generate a capacitance signal.

Step S802 , acquiring position information and pressure information of the capacitance signal sensed in each sub-writing area relative to the entire writing area.

Step S803 , according to the position information and pressure information of the capacitive signals sensed in different sub-writing areas, generate a corresponding input track for each sub-writing area.

Specifically, when the user's finger or the capacitive pen touches the writing area, a capacitance is generated on the surface of the writing area. Because the capacitive sensor array is arranged in the writing area, the capacitive sensor array, together with a special chip, continuously tracks the trajectory of the capacitance of the user's finger. After processing the capacitive signal, accurate positioning can be achieved at every moment. The position of the finger (such as X, Y coordinates), and the change in the capacitance value formed by the change in the distance between the finger and the writing area (the change in the pressure determined according to the pressure information), determine the Z coordinate, and finally complete the X, Y, Z Coordinate value determination.

Further, after determining the coordinate values corresponding to all the capacitance signals, it is determined which sub-writing area the coordinate values belong to, so as to determine which sub-writing area the corresponding capacitance signal is generated in. Accordingly, all the coordinate values are written according to the sub-writing area. The coverage of the area is divided to obtain the coordinate values corresponding to all the capacitive signals generated in each sub-writing area, and the input track in each sub-writing area is generated for the coordinate values corresponding to the capacitive signals generated in different sub-writing areas.

Exemplarily, when two people perform writing operations with their fingers in the sub-writing area A and the sub-writing area B on the desktop of the conference table at the same time, the coordinate values corresponding to all capacitance signals are obtained, such as including (2, 3), ( 2, 4), (3, 4), (17, 18) and (18, 19) these five coordinate values, and then judge the area to which the corresponding position of each coordinate value belongs. After judgment, (2, 3) , (2, 4) and (3, 4) correspond to the position of the sub-writing area A, and the positions corresponding to (17, 18) and (18, 19) belong to the sub-writing area B; then according to (2, 3), (2, 4) and (3, 4) generate the input track in the sub-writing area A; generate the input track in the sub-writing area B according to (17, 18) and (18, 19).

In this embodiment, multiple people can simultaneously write in multiple sub-writing areas of the same input device by means of finger touch, and the input trajectories generated in different sub-writing areas do not interfere with each other.

FIG. 9 is a schematic flowchart of a multi-area touch input processing method according to another exemplary embodiment of the present invention. This embodiment further describes the multi-area touch input processing method on the basis of the embodiment shown in FIG. 8 in detail. .

As shown in FIG. 9 , the method provided by this embodiment may include the following steps.

Step S901, receiving the capacitive signal and the electromagnetic signal respectively sensed by each sub-writing area.

Specifically, when multiple people use their fingers and electromagnetic stylus to perform writing operations in multiple sub-writing areas of the input device at the same time (as shown in FIG. For writing operation, two fingers perform writing operations in sub-writing areas C and D respectively), and multiple sub-writing areas generate electromagnetic signals and capacitive signals.

In step S902, the position information corresponding to the capacitive signal and the position information corresponding to the electromagnetic signal are obtained respectively.

Step S903 , according to the position information corresponding to the capacitive signal and the position information corresponding to the electromagnetic signal, respectively generate input trajectories corresponding to different signal types.

Specifically, based on the signal types (including electromagnetic signals and capacitive signals) sensed by the input device, the position information corresponding to all the signals is divided, and the position information corresponding to the electromagnetic signal and the position information corresponding to the capacitive signal are obtained respectively.

For example, the first user performs a writing operation in the sub-writing area A on the desktop of the conference table through an electromagnetic stylus, while the second user performs a writing operation in the sub-writing area C through a finger. The coordinate values corresponding to all signals sensed by the input device include (1, 5), (6, 5), (4, 6) and (9, 8). 5) and (6, 5), the coordinates corresponding to the capacitance signal are (4, 6) and (9, 8). According to the coordinate values, the input track corresponding to the electromagnetic signal and the input track corresponding to the capacitance signal are obtained respectively.

In this embodiment, multiple people use the electromagnetic touch pen and fingers to simultaneously perform writing operations on one input device.

It can be understood that, when there is only one pen or one finger in a sub-writing area to perform the writing operation, the processing method in the embodiment shown in FIG. sub-writing areas, and then get the input track in each sub-writing area. When the same sub-writing area contains both the electromagnetic stylus for writing and the finger for writing (as shown in Figure 4c, the electromagnetic stylus and the finger simultaneously perform writing in the sub-writing area D), the The type of signal sensed by the input device divides the coordinates corresponding to all the sensed signals to distinguish the writing track of the electromagnetic stylus and the writing track of the finger in the same sub-writing area. Thus, multiple pens and fingers can simultaneously perform writing operations in the same writing area.

Optionally, after the input track is generated, the method for sending the input track to the display terminal for display may include the following methods.

In one embodiment, according to the preset correspondence between the sub-writing areas and the display terminals, the respective input trajectories in each sub-writing area may be sent to the corresponding display terminals for display, and the sub-writing areas and the Display terminals are in a one-to-one correspondence.

Specifically, as shown in FIG. 10 , each sub-writing area corresponds to a display terminal, such as four sub-writing areas A, B, C and D on the desktop, and the input track in the sub-writing area A is correspondingly sent to the display terminal a for display , the input track in sub writing area B is sent to display terminal b for display, the input track in sub writing area C is sent to display terminal c for display, and the input track in sub writing area D is sent to display terminal d for display.

In another possible embodiment, all input trajectories in the multiple sub-writing areas are sent to one display terminal for display. As shown in FIG. 11 , one display terminal includes all input contents in the four sub-writing areas. The content in the sub-writing area is distinguished by the identification of the sub-writing area or the color of the input track. For example, identification A: xxxx indicates that the input track in the sub-writing area A is "xxxx"; identification B: yyyy indicates the sub-writing area The input trajectory in B is "yyyy" etc.

In another possible embodiment, the sending the at least one input track to a display terminal for display includes: dividing the display area of the display terminal into a plurality of sub-display areas according to a screen division instruction input by the user , the screen division instruction includes the number of sub-display areas and the position information of each sub-display area; the respective input tracks in the multiple sub-writing areas are sent to any sub-display area for display, or, according to a preset sub-display area The corresponding relationship between the writing area and the sub-display area is to send the respective input tracks in each sub-writing area to the corresponding sub-display area for display.

Specifically, referring to FIG. 12 , the desktop of the conference table includes four sub-writing areas A, B, C and D, and the screen of the display terminal is pre-divided into four display areas, which are a1, b1, c1 and d1 respectively. The correspondence between the writing area and the display area is A- a1, B- b1, C- c1, D- d1, then, the input track in the sub-writing area A is sent to the display area a1 for display, and the input track in the sub-writing area B is displayed. The input track is sent to the display area b1 for display, the input track in the sub-writing area C is sent to c1 for display, and the input track in the sub-writing area D is sent to the display area d1 for display; or, set four sub-display areas corresponding to one screen A display area of the Identify or enter the color of the track to distinguish.
