step 402, receiving a first touch operation generated on the interactive device body, and performing corresponding processing according to the first touch operation.

Specifically, the part of the intelligent interactive tablet except the touch frame can form the interactive device main body, and the interactive device main body can execute all functions which can be executed by the intelligent interactive tablet by combining the touch frame arranged outside the combined blackboard.

And processing corresponding to the first touch operation is used for representing processing performed according to the function triggered by the first touch operation. For example, if the first touch operation is a writing operation on the whiteboard application interface, generating corresponding writing handwriting on the whiteboard application interface according to the first touch operation; for another example, if the first touch operation is an operation of clicking a preset control, the function corresponding to the preset control is executed according to the first touch operation.

It should be noted that the above steps may be executed before, after, or simultaneously with any step, and the timing for executing the step is not limited, and specifically, when the intelligent blackboard receives the first touch operation, corresponding processing may be performed according to the first touch operation.

Specifically, the touch frame may be an infrared touch frame, the infrared touch frame includes an infrared emitting and receiving sensing element, an infrared detection network is formed on the surface of the combination blackboard, and any touch object can change the infrared ray on the contact to realize the touch screen operation. The interactive device body itself may not have a touch function, and may also have an electromagnetic touch function. The blackboard body can be a traditional blackboard allowing chalk to be used for writing, can also be a white board allowing an oil pen to be used for writing, and can also be other panels capable of writing.

The interactive device main body is spliced with the blackboard bodies, the interactive device main body can be embedded among the plurality of blackboard bodies, a plurality of edges of the interactive device main body are adjacent to the plurality of blackboards, or the interactive device main body is only adjacent to one blackboard body. Several examples are given below, and further combinations are not described herein.

Fig. 5a is a schematic diagram of an alternative combination of an interactive device main body and a blackboard body according to an embodiment of the present application, and in conjunction with fig. 5a, the interactive device main body 10 is disposed between an upper blackboard body and a lower blackboard body 20, and a touch frame 30 is disposed at the periphery of the two. Fig. 5b and 5c are schematic diagrams of two alternative combinations of the interactive apparatus main body and the blackboard body according to the embodiment of the present application, in fig. 5b, the interactive apparatus main body 10 is disposed at the left side of one blackboard body 20, and the side touch frame 30 is disposed at the periphery of the two; in fig. 5c, the interactive apparatus main body 10 is disposed on the upper side of one blackboard body 20, and the side touch frame 30 is also disposed on the periphery of both.

In the scheme, the touch frame is arranged on the peripheries of the interactive device main body and the blackboard body, so that the interactive device main body and the blackboard body can be seamlessly spliced. And because the display screen of the interactive equipment main body is positioned in the infrared detection network formed by the touch frame, the processing precision of the touch data is ensured. In conclusion, the touch frame is arranged on the peripheries of the interactive device main body and the blackboard body, so that the interactive device main body and the blackboard body can be seamlessly spliced while the processing precision of touch data is guaranteed.

And step 404, receiving a second touch operation generated on the blackboard body, and generating a corresponding writing according to the second touch operation.

When a user operates on the interactive device main body, the touch frame can detect a first touch operation, and when the user performs a second touch operation on the blackboard body, the blackboard body is also positioned in the infrared detection network formed by the touch frame, so that the second touch operation can be detected by the touch frame.

The object for generating the second touch operation may be a finger of the user, may also be chalk, and may also be other writing tools or writing devices.

It should be noted that, a drawing board writing unit is installed on the interactive device main body, and the drawing board writing unit may generate a first writing interface for displaying the writing handwriting. Under the condition that the interaction device body displays the first writing interface, the first writing interface follows the second touch operation to generate writing corresponding to the second touch operation together, under the condition that the interaction device body does not display the first writing interface, the drawing board writing unit synchronously records the writing corresponding to the second touch operation, and the recorded writing can be called out and displayed.

In the above scheme, the touch frame may process the first touch operation and the second touch operation. That is, the touch frame detects touch operations at all positions included in its detection range. When the first touch operation and the second touch operation exist at the same time, the touch frame can process the first touch operation and the second touch operation at the same time in a multi-point touch processing mode.

And 406, displaying a first writing interface corresponding to the drawing board writing unit on the current display interface of the interactive device main body in an overlapped mode, wherein the drawing board writing unit is a functional module which is operated on the interactive device main body and is used for writing and editing handwriting.

Specifically, the drawing board writing unit supports the touch function of the blackboard body, allows the drawing board writing unit to generate writing handwriting corresponding to the second touch operation, the first writing interface is the writing interface corresponding to the blackboard body, and the first writing interface can be opened in the drawing board writing unit to display the writing handwriting generated according to the second touch operation. Further, the generated handwriting is allowed to be edited by the drawing board writing unit.

The user writes with a finger on the blackboard body, and since the finger cannot generate handwriting on the blackboard body, the content written by the user does not exist on the blackboard body (the dotted line part represents the track written by the finger), but the touch frame recognizes the second touch operation and displays the content written by the user on the first writing interface.

Fig. 6b is a schematic diagram of writing on a blackboard body by chalk according to an embodiment of the present application, in this example, a first writing interface is displayed on an interactive device main body, the first writing interface has a display area, and other controls such as a toolbar may be further included in the display area. The user writes on the blackboard body with chalk, so that the blackboard body has the content written by the user, and the touch frame recognizes the second touch operation, so that the content written by the user is displayed in the first writing interface.

In an optional embodiment, the drawing board writing unit is opened in a classroom, the first writing interface is displayed, two students can answer questions on the two blackboard bodies on the two sides of the interactive device main body respectively, and finally the content of the answered questions is displayed on the first writing interface of the interactive device main body, so that a teacher can conveniently and intensively explain and store the questions, and writing handwriting generated on the blackboard bodies can be stored and/or edited in the modes of pictures and the like.

In an optional embodiment, in a teaching scene, the interactive device main body plays the electronic courseware, and meanwhile, a teacher can write on the blackboard body to form writing handwriting. The writing corresponding to the part of the blackboard writing can be displayed in the first writing interface, so that interaction can be performed between the writing on the blackboard body and the multimedia content on the interactive device main body.

It should be noted that, after the writing handwriting corresponding to the blackboard writing is displayed on the first writing interface, the teacher may determine whether to drag the writing handwriting to the whiteboard application interface according to the actual situation, so as to store the current blackboard writing. If the writing handwriting corresponding to the blackboard writing is dragged to the whiteboard application interface, the writing handwriting corresponding to the blackboard writing and other contents on the whiteboard application interface can be stored together, and if the writing handwriting corresponding to the blackboard writing is not arranged to the whiteboard application interface, the writing handwriting displayed in the first writing interface can be stored independently, so that the original contents in the whiteboard application interface cannot be interfered.

It should be noted that the interactive device main body generates the writing handwriting according to the second touch operation, which may be to obtain the touch point, calculate the width of the touch point, and calculate the skeleton line of the handwriting corresponding to the touch point, thereby determining the contour line of the handwriting, then obtain the inflection point in the contour line, generate the bezier curve corresponding to the inflection point, use the bezier curve as the smoothed contour line, and draw the handwriting according to the smoothed contour line, but is not limited to this method.

It should be further noted that, in an alternative embodiment, the position on the blackboard body has a corresponding relationship with the position in the first writing interface, and the position of the handwriting in the first writing interface may be determined according to the position where the second touch operation is generated.

And 4010, receiving erasing operation on the handwriting on the blackboard body, and erasing the handwriting according to the erasing operation.

In another optional embodiment, whether the user is erasing may be determined according to second touch operation data corresponding to the second touch operation, and specifically, the determination may be performed by using a touch area recorded in the second touch operation data. For example, if the width is greater than 48 and the height is greater than 72 in the second touch operation data, it can be determined that the blackboard eraser is currently in the erasing process. At this time, the drawing board writing unit executes the handwriting erasing process. The erasing method can be used for extracting the touch area, namely the width and the height, in the second touch operation data through the second touch operation data reported by the analysis module in the drawing board writing unit access layer, so that the fact that the user performs the erasing operation can be judged. The erasing process may be based on geometric hit test calculation, which may be obtained by the skilled person with the knowledge disclosed, and will not be described herein. In the first writing interface, the drawing board writing unit can be defaulted to use 60 times of frequency refreshing per second, so that the first writing interface can be changed and refreshed immediately as long as the writing is changed, and the synchronous erasing of the writing in the blackboard body and the first writing interface is completed.

It is noted that, in addition to the erasing operation, other modifications may be made to the writing shown in the first writing interface, such as: colors, line types, etc., which will not be described in detail herein.

In the whiteboard application interface, a user can realize writing, drawing, erasing and other operations similar to an entity blackboard, and further has better digital functions of moving, storing, zooming, inserting pictures, adjusting colors, setting stroke weights and the like. Writing-based operations in whiteboard applications are a mature realization of the prior art and are not described in detail in this solution. In practical applications, the whiteboard application may also be named as whiteboard writing application, electronic whiteboard application, collaborative whiteboard application, etc., and the application for implementing the above functions is equivalent to the whiteboard application of the present application regardless of changes in the name.

In this example, the end point of the move operation is still located in the first writing interface.

It should be noted that in the above solution, the end point of the move operation is located in the whiteboard application interface. That is, in the case that the first writing interface is not full of the entire display interface of the intelligent interactive tablet, the selected writing trace is dragged to the outside of the first writing interface, which is described below.

The scheme is used for moving the writing in the first writing interface to the whiteboard application interface. In the above scheme, the whiteboard application interface is further included below the first writing interface, and when the selected writing track is dragged out of the first writing interface, it is considered that the user needs to drag the selected drawing content from the first writing interface to the whiteboard application interface, so that the selected writing track is moved from the first writing interface to the whiteboard application interface.

Fig. 10a and 10b are schematic diagrams illustrating dragging of drawing contents from a first writing interface to a whiteboard application interface according to an embodiment of the application, where, as shown in fig. 10a, a user drags a selected writing track from the first writing interface to the whiteboard application interface, and as shown in fig. 10b, the selected writing track is displayed in the whiteboard application interface.

In the above scheme, the property of the first writing interface may be adjusted, where the property includes a size of the first writing interface and a position of the first writing interface in the display interface of the interactive device main body.

In an alternative embodiment, the first writing interface may be resized by dragging an edge of the first writing interface; in another alternative embodiment, the position of the first writing interface in the display interface of the interactive device body can be adjusted by dragging the designated position in the first writing interface.

As an alternative embodiment, the number of the blackboard bodies is at least two, wherein,

the first writing interface is provided with at least two subareas, and each subarea is used for displaying the writing handwriting on the corresponding blackboard body; alternatively, the first and second electrodes may be,

the number of the first writing interfaces is at least two, and each first writing interface is used for displaying the writing on the corresponding blackboard body.

Under the condition that the intelligent blackboard comprises two blackboard bodies, the scheme provides two handwriting display modes.

In the first mode, the two blackboard bodies share the same first writing interface, that is, the writing handwriting of the two blackboard bodies can be displayed on the same first writing interface. However, the first writing interface is provided with two subareas, each subarea corresponds to one blackboard body, and corresponding writing handwriting is generated according to the second touch operation on the corresponding blackboard body.

Fig. 11a is a schematic diagram of a first writing interface displaying writing traces on two blackboard bodies in a partitioned manner according to an embodiment of the present application, and as shown in fig. 11a, the first writing interface is divided into a left part and a right part, which respectively correspond to the left blackboard body and the right blackboard body, and a boundary between the left part and the right part may be displayed or hidden. Correspondingly, the handwriting generated on the left blackboard body can be displayed on the left subarea of the first writing interface, and the handwriting generated on the right blackboard body can be displayed on the right subarea of the first writing interface.

In the second mode, the two blackboard bodies respectively use different first writing interfaces together, that is, the writing handwriting of the two blackboard bodies can be displayed on the different first writing interfaces.

Fig. 11a is a schematic diagram of two first writing interfaces respectively displaying writing on two blackboard bodies according to an embodiment of the present application, and in combination with fig. 11b, two first writing interfaces are currently displayed and respectively correspond to the left blackboard body and the right blackboard body. Accordingly, the handwriting generated on the left blackboard body is displayed on the first writing interface 1 on the left side, and the handwriting generated on the right blackboard body is displayed on the first writing interface 2 on the right side.

As an alternative embodiment, the touch frame includes: the infrared signal of transmission only covers the first infrared unit of mutual equipment main part, the infrared signal of transmission covers the second infrared unit of mutual equipment main part and blackboard body to and the infrared signal of transmission only covers the third infrared unit of blackboard body, and mutual equipment main part is installed and is supported the touch function's of blackboard body and predetermine the application, and the second touch operation that generates on the blackboard body is being received, before the corresponding handwriting is write according to second touch operation generation, the method still includes:

sending a notification message to the micro control unit after the preset application is started, wherein the notification message is used for indicating that the interactive equipment main body runs the preset application;

the micro control unit controls a third infrared unit of the touch frame to start and operate.

Specifically, the first infrared unit and the second infrared unit are infrared units that can form an infrared detection net on the surface of the interactive device body, so as to detect the first touch operation generated on the interactive device body. And the third infrared unit is an infrared unit which can form an infrared detection net on the surface of the blackboard body after being combined with the second infrared unit, so that the second touch operation generated on the intelligent blackboard is detected.

Referring to fig. 12, in an example in which the interactive device main body is disposed between the left and right blackboard bodies, the infrared unit in the touch frame includes three portions, one of which is a first infrared unit 31 in which an infrared signal can only cover the interactive device main body, the first infrared unit 31 being in contact with the interactive device main body, and the second of which is a second infrared unit 32 in which an infrared signal can cover both the interactive device main body and the blackboard body, the second infrared unit 32 being opposite to the left and right sides of the interactive device main body, and the infrared signal can only cover a third infrared unit 33 of the interactive device main body, the third infrared unit 33 being located between the first infrared unit 31 and the second infrared unit 32.

It should be noted that, in the examples of fig. 5b and 5c, since there is no touch frame that is not adjacent to and does not correspond to any one side of the smart interaction tablet, in the examples of the two smart blackboards, only the first infrared unit and the second infrared unit are included, and the third infrared unit is not included.

The preset application is an application which is installed on the interactive device main body and can support the touch function of the blackboard body, for example, a multi-user answer application program which is used for summarizing answer contents written by students on the blackboard body on the interactive device main body, a blackboard-writing recording application which is used for recording blackboard-writing of teachers on the blackboard body on the interactive device main body, and the like. When the application programs are started, the third infrared unit is triggered to start running. After the third infrared unit is started to operate, the second touch operation generated on the blackboard body can be detected, and then the function of preset application is realized.

Fig. 13 is a schematic diagram of triggering the third infrared unit to start according to an embodiment of the present application, and with reference to fig. 13, after the preset application is started, the touch frame is triggered to start the third infrared unit, and the touch frame acquires second touch operation data through combination of the third infrared unit and the second infrared unit; and after the preset application exits, sending a notification message of the exiting of the preset application to the touch frame, so as to trigger the touch frame to close the third infrared unit, further reduce the data processing pressure of the touch frame, and reduce the energy consumption of the intelligent blackboard.

In the above scheme, the touch functions of the first infrared unit and the second infrared unit are started and operated together when the interactive device main body is started, that is, the first infrared unit and the second infrared unit always keep an operating state when the interactive device main body is started. This scheme is for a system that is compatible with the body of the interactive device and other applications within the system. The method is logically equivalent to the original scheme that only the touch frame is added on the periphery of the intelligent interaction panel by only depending on the first infrared unit and the second infrared unit, and the scheme can be completely compatible with the previous scheme and can be supported without changing any system and software on the intelligent interaction panel. And the third infrared unit is triggered to start when the preset application is started, that is, the third infrared unit is waken to start when the preset application is started.

The first infrared unit and the second infrared unit are used for detecting the first touch operation generated on the interactive device main body, and any touch operation on the interactive device main body needs to be detected by the first infrared unit and the second infrared unit, so that the first infrared unit and the second infrared unit are always kept in an operating state, and the touch operation of the interactive device main body is supported; and the third infrared unit is used for detecting second touch operation generated on the blackboard body, the blackboard body can be used as a traditional blackboard only except for being combined with the touch frame to provide second touch operation for preset application, therefore, the third infrared unit can not be started when the blackboard body is only used as the traditional blackboard, when the preset application is started, namely when the second touch operation needs to be detected, the third infrared unit is triggered to start, and therefore, the effects of reducing data processing amount, reducing the calculation pressure of the touch frame and saving energy consumption are achieved.

It should be noted that the preset application may be triggered by the user to be restarted after the interactive device main body is started, or may be set to be started, that is, the preset application is started together with the startup of the interactive device main body, and in the case that the preset application is started, the starting mode of the third infrared unit is also started as the startup of the preset application.

As an optional embodiment, the touch frame sends the second touch operation data detected on the blackboard body to the processing module through the second transmission channel, including: the touch frame encapsulates the second touch operation data through a preset private protocol, wherein the private protocol is used for encapsulating the second touch operation data into a preset uniform format; and sending the packaged second touch operation data to a processing module through a second transmission channel.

Specifically, the above-mentioned proprietary protocol is used to mean that the protocol is not a well-known protocol such as TCP/IP protocol, and the content of the constraints of the protocol is only known by the touch frame and the preset application.

In the above solution, in order to enable the interaction device to process the second touch operation data, the second touch operation data is encapsulated by using a private protocol, so that when the interaction device main body receives the second touch operation data, the interaction device main body can decapsulate and process the second touch operation data according to the private protocol.

Fig. 14 is a schematic diagram of sending second touch operation data to a processing module by a touch frame according to an embodiment of the present application, and in an alternative embodiment, with reference to fig. 14, after the touch frame encapsulates the second touch operation data by the above-mentioned private protocol, the second touch operation data is sent to a USB device of the processing module, and a preset application obtains the second touch operation data by monitoring a transmission channel between the USB device of the processing module and the touch frame.

As an alternative embodiment, the preset unified format includes: the device comprises a fixed information head, a main command, an auxiliary command and touch information, wherein the main command is used for indicating that the touch operation is a second touch operation packaged by a private protocol, and the auxiliary command is used for indicating a blackboard body for generating the second touch operation.

Specifically, the fixed header and the main command may be default values, the sub command is used to indicate which blackboard body the touch data comes from when a plurality of blackboard bodies are included, and the touch information is actual data generated according to the touch operation.

In an alternative embodiment, the format may be a unified format for encapsulation as a proprietary protocol, with the format shown in the following table.

First, the data in table one is explained:

data [0]: 1 st point state (DOWN: 0x04;

data [1]: 1 st point ID (0 x00, from small to large);

data [2]: 1 st point X coordinate low byte data;

data [3]: 1 st point X coordinate high byte data;

data [4]: 1 st point Y coordinate low byte data;

data [5]: 1 st point Y coordinate high byte data;

data [6]: 1 st dot width W low byte data;

data [7]: 1 st dot width W high byte data;

data [8]: 1 st dot height hdigyte data;

data [9]: 1 st dot height hdigyte data;

data [10-19]: point 2 data, (if there is no touch point, fill ID =0xFF, data segment XYWH all 0);

data [20-29]: point 3 data, (if there is no touch point, fill ID =0xFF, data segment XYWH all 0);

data [30-39]: point 4 data, (if there is no touch point, fill ID =0xFF, data segment XYWH all 0);

data [40-49]: 5 th point data, (if there is no touch point, fill ID =0xFF, data segment XYWH all 0);

data [50-59]: data at point 6, (if there is no touch point, fill ID =0xFF, data segment XYWH all 0);

data [60]: the number of currently active touch points. If the current point number is larger than 6 points, the 1 st packet data contains the effective point number, and the effective point number of the subsequent split packet is 0.

In the above example, the second touch operation data generated on the left and right blackboard bodies are respectively adopted with different command values, which facilitates to add more blackboard bodies, for example, add blackboard bodies above or below the interactive device main body. The details of the protocol are as follows:

touch messages of the private protocol are all sent to the processing module from the touch frame, and the process of sending the touch frame to the PC module can be carried out through the MCU optionally or not through the MCU equipment and then to the processing module. The content of table one represents that the touch data passes through the MCU device and then to the processing module, so McuToPc appears in the protocol, that is, represents that the touch data is sent from the MCU to the processing module. The touch data can be transmitted by a USB or an I2C mode, and the transmission mode is not limited. The content transferred may use a fixed 64 bytes by default.

The touch data content meaning of the proprietary protocol is as follows:

table a third column represents the 0 th byte: 0xFA is fixed to the 1 st byte of the message header;

the first fourth column of the table represents the master command, which represents that the data is encapsulated by the private protocol, represented using a value of 0x 00;

the fifth column of the table represents byte 2: the auxiliary command is used for distinguishing the touch data of which physical blackboard is, the blackboard body on the left side in the upper table is represented by 0x01, the blackboard body on the right side is represented by 0x02, and more blackboards are represented by different values;

the sixth column of the table represents the subsequent 3 rd to 63 th bytes, specifically the actual touch data. The actual touch data contains the Id points of the touches, as well as the coordinates and touch areas, where the Id points of the touches are used to distinguish between different touch points when multi-finger touches are made, e.g., the Id points of touches of the same finger are all the same and different fingers are all different.

Example 2

According to an embodiment of the present invention, an embodiment of an intelligent blackboard is provided, and it should be noted that fig. 3 is a schematic structural diagram of an intelligent blackboard according to an embodiment of the present application, where the intelligent blackboard includes: at least one blackboard body 20, an interactive device main body 10 and a touch frame 30, wherein at least one edge of the interactive device main body 10 is spliced with at least one blackboard body 20 to form a combined blackboard, the touch frame 30 is arranged on the periphery of the combined blackboard, wherein,

the touch frame is used for receiving a first touch operation generated on the interactive equipment main body and a second touch operation generated on the blackboard body; the interaction device main body is used for carrying out corresponding processing according to the first touch operation and generating corresponding writing handwriting according to the second touch operation; a first writing interface corresponding to a drawing board writing unit is displayed on a current display interface of the interactive equipment main body in an overlapping mode, and the drawing board writing unit is a functional module which is operated on the interactive equipment main body and is used for writing and editing handwriting; displaying the writing handwriting in a first writing interface; and receiving the erasing operation of the handwriting on the blackboard body, and erasing the handwriting according to the erasing operation.

Specifically, the portion of the intelligent interactive panel except the touch frame can form the interactive device main body, and the interactive device main body can execute all functions that the intelligent interactive panel can execute by combining the touch frame arranged outside the combined blackboard.

It should be noted that the above steps may be executed before, after or simultaneously with any step, and the timing for executing the step is not limited, specifically, when the intelligent blackboard receives the first touch operation, corresponding processing may be performed according to the first touch operation.

The interactive device main body is spliced with the blackboard bodies, the interactive device main body can be embedded among the plurality of blackboard bodies, a plurality of edges of the interactive device main body are adjacent to the plurality of blackboards, and the interactive device main body can also be adjacent to one blackboard body. Several examples are given below, and further combinations are not described herein.

In the above scheme, the touch frame may process the first touch operation and the second touch operation. That is, the touch frame detects touch operations at all positions included in its detection range. When the first touch operation and the second touch operation exist at the same time, the touch frame can process the first touch operation and the second touch operation at the same time through a multi-point touch processing mode.

The drawing board writing unit supports the touch function of the blackboard body, allows the drawing board writing unit to generate writing handwriting corresponding to the second touch operation, and opens the first writing interface in the drawing board writing unit to display the writing handwriting generated according to the second touch operation, wherein the first writing interface is the writing interface corresponding to the blackboard body. Further, the generated writing is allowed to be edited by the palette writing unit.

The interactive device main body generates the writing handwriting according to the second touch operation, which may be to obtain a touch point, calculate the width of the touch point, and calculate a skeleton line of the handwriting corresponding to the touch point, thereby determining a contour line of the handwriting, then obtain an inflection point in the contour line, generate a bezier curve corresponding to the inflection point, use the bezier curve as a smoothed contour line, and draw the handwriting according to the smoothed contour line, but is not limited to this method.

In another optional embodiment, whether the user is erasing may be determined according to second touch operation data corresponding to the second touch operation, and specifically, the determination may be performed by using a touch area recorded in the second touch operation data. For example, if the width is greater than 48 and the height is greater than 72 in the second touch operation data, it can be determined that the blackboard eraser is currently in the erasing process. At this time, the drawing board writing unit executes the handwriting erasing process. The erasing method can be used for extracting the touch area, namely the width and the height, in the second touch operation data through the second touch operation data reported by the analysis module in the access layer of the drawing board writing unit, so that the user can be judged to perform the erasing operation. The erasing process may be based on geometric hit test calculation, which may be obtained by a person skilled in the art with the knowledge disclosed, and will not be described herein. In the first writing interface, the drawing board writing unit can be defaulted to refresh with the frequency of 60 times per second, so that the first writing interface can be changed and refreshed immediately as long as the writing is changed, and therefore synchronous erasing of the writing in the blackboard body and the first writing interface is completed.

According to the scheme, the blackboard body is brought into the recognition range of the touch frame, so that the interactive device main body can be seamlessly spliced with the blackboard body under the condition of ensuring the touch precision, and the touch operation generated on the blackboard body can be recognized and processed. To intelligent blackboard, in order to improve its intelligent degree, need enlarge the size of the mutual flat board of intelligence usually, nevertheless enlarge the mutual flat board of intelligence and can cause the cost to rise seriously, and above-mentioned scheme can be under the condition of not enlarging the size of the mutual flat board of intelligence, the scope that can carry out touch operation has been enlarged, and to intelligent blackboard, blackboard body self's usage has still been kept, and then under the condition of maintenance cost, the intelligent degree of intelligent blackboard has been improved, the intelligent blackboard of having solved among the prior art is embedded into the mutual flat board of intelligence, but intelligent degree still lower technical problem.
