The present invention is an electronic whiteboard system and a driving method for independently processing a plurality of inputs. More specifically, when a writing function is performed simultaneously using a plurality of touch pens on one electronic whiteboard, a plurality of input touch pens are used. By creating a Bluetooth device driver corresponding to each pen and then independently processing each of the plurality of inputs based on the touch pen information received through it and the coordinate information for each of the plurality of inputs generated by the electronic whiteboard, It relates to an electronic whiteboard system that can independently process multiple inputs and a method of driving the same, capable of performing multiple writing functions input simultaneously on an electronic whiteboard.

This is because it has a structure that does. In other words, in the case of the Windows OS used in most electronic whiteboards, even if input is made using a plurality of different touch pens, only one input is transmitted to the writing program, so multiple handwriting cannot be performed at the same time.

Figure 1 schematically shows the configuration of a prior art electronic whiteboard system.

Specifically, Figure 1 shows the configuration of a prior art electronic whiteboard system using a touch pen. The electronic whiteboard system includes an electronic whiteboard and a touch pen capable of inputting handwriting on the electronic whiteboard capable of communicating with a computing module. When you want to change the writing style, for example, pen thickness, color, or type, you can write on an electronic pen as an advanced technology compared to the early electronic whiteboard system that selects a specific interface displayed on the electronic whiteboard. It corresponds to a technology that can set the style of .

The computing module preferably includes one or more processors and one or more memories, and has an operating system (hereinafter referred to as OS, Operating System) installed for connection to external devices or operation of internal devices. Typically, for compatibility with a PC, Microsoft's Windows OS is installed in the computing module, and the OS transmits only a single touch input to a writing program.

More specifically, as shown in Figure 1, the coordinate information of the input input from the electronic whiteboard is directly transmitted to the OS by the HID (Human Interface Device) driver, and the transmitted coordinate information is transmitted to the writing program pre-stored in the computing module. is passed on. In the case of information input from the same class, the HID driver processes only one input.

For example, when two different mice are connected to one PC, when one mouse is operated, the other mouse does not operate until the existing mouse operation ends. In other words, even if multiple inputs are entered using two or more touch pens on one electronic whiteboard, the OS processes only one input, so the different touch pens cannot be processed independently from each other, and the style information set in one touch pen is not processed independently. This affects the input of other touch pens.

In other words, when the input of the electronic whiteboard is transmitted to the HID driver, regardless of the intention of the system designer, the OS itself transmits only one input to the writing program, so multiple input information cannot be processed according to the designer's intention. Because of this, there is a problem that multitouch cannot be performed independently.

In addition, the writing style information set on the touch pen is transmitted to the writing program through the Bluetooth device driver and Windows Application, and the writing program receives information from the user based on the coordinate information received from the HID driver and the writing style information received from the electronic pen. The inputted handwriting is displayed on the electronic whiteboard.

Therefore, even if a plurality of touch pens were used in connection with the computing module, it was impossible to independently process a plurality of inputs due to structural limitations of the commonly used OS. The inventor of the present invention invented the present invention to overcome the limitations of the prior art described above, and a detailed description of the present invention will be provided later in the description of FIGS. 2 to 9.

Do it as

Specifically, the electronic whiteboard 1000 and the touch pen 2000 communicate with the computing module 3000 in different ways, and the computing module 3000 communicates with the electronic whiteboard 1000 and the touch pen 2000. The writing function can be performed by executing an application program pre-stored in the computing module 3000 based on the information received from each.

As shown in FIG. 2, the computing module 3000 can communicate with a plurality of touch pens 2000.

A more detailed description of each configuration will be provided below.

In addition, the configuration shown in Figure 2 corresponds to the minimum configuration for explaining the technical features of the present invention, and the computing module 3000 may further include configurations necessary for the operation of the electronic whiteboard system in addition to the configuration mentioned above. there is.

Figure 3 schematically shows the configuration of an electronic whiteboard 1000 and a touch pen 2000 according to an embodiment of the present invention.

Coordinate information can be generated for each input.

The coordinate information is generated in real time, and the generated coordinate information (or coordinate information stream) can be transmitted to the computing module 3000 through the coordinate information transmitter 1500. As an embodiment of the present invention, the coordinate information transmission unit 1500 includes a USB communication module and a USB connector, and the coordinate information generated by the electronic whiteboard 1000 is transmitted to the computing module 3000 through a USB connection method. It is delivered.

Referring to FIG. 2, the pressure sensor 2100 is provided at a position corresponding to the pen tip of the touch pen 2000, and can sense the pressure of a touch input by the user and generate pressure sensitivity information. Preferably, the intensity of pressure input by the user can be sensed by dividing it into 1 to 1024 levels. The pressure reduction information generated by the pressure sensor 2100 may be reflected in the thickness of the pen displayed on the display panel 1100.

Additionally, when the pressure sensor 2100 senses pressure, the touch pen 2000 generates touch pen information for the corresponding touch pen 2000 and transmits the touch pen information to the computing module 3000. That is, the pressure sensor 2100 can function as a communication switch between the touch pen 2000 and the computing module 3000 (ON when pressure is sensed/OFF when pressure is not sensed).

Figure 4 schematically shows the overall driving process of the electronic whiteboard system according to an embodiment of the present invention.

Schematically, Figure 4 shows the overall process of providing a writing function corresponding to information input from the user. Specifically, as described above, when coordinate information and touch pen information are transmitted from the electronic whiteboard 1000 and the touch pen 2000 to the computing module 3000, the bridge module unit 3300 of the computing module 3000 Writing information is generated based on the coordinate information and touch pen information and transmitted to the HID driver unit 3400. The HID driver unit 3400 generates input information based on the received writing information, and the generated input information is transmitted to the application operation unit 3500. Thereafter, by displaying the operation results of the application program operation unit 3500 on the display panel 1100 of the electronic whiteboard 1000, a writing function can be provided to the user.

When compared to the prior art shown in FIG. 1, the present invention does not input information transmitted from the electronic whiteboard and touch pen directly into the OS through the HID driver unit, but rather uses a coordinate information receiver, a touch pen information receiver, and a bridge module unit. The technical characteristic is that it is transmitted to the HID driver unit after processing. In other words, the present invention aims to solve the structural problems of the prior art described above in the description of FIG. 1 through this configuration. Below, the driving process of each component will be described in more detail.

Figure 5 schematically shows a process of receiving information from each of the electronic whiteboard 1000 and the touch pen 2000 according to an embodiment of the present invention.

As shown in FIG. 5, the computing module 3000 supports USB standard communication between the operating system of the computing module 3000 and the electronic whiteboard 1000, and coordinates from the electronic whiteboard 1000. A coordinate information receiving unit 3100 that receives information; and a touch pen information receiver 3200 that supports Bluetooth communication between the operating system and each of the plurality of touch pens 2000 and receives touch pen information from each of the plurality of touch pens 2000. .

Specifically, as shown in FIG. 5, coordinate information generated by the electronic whiteboard 1000 is transmitted to the coordinate information receiver 3100. The coordinate information is preferably transmitted through a wired communication method, and more preferably through a USB communication cable. That is, the coordinate information transmitting unit 1500 and the coordinate information receiving unit 3100 include a USB connector (not shown), and the coordinate information receiving unit 3100 further includes a USB driver.

In the prior art, information input from the electronic whiteboard 1000 is transmitted to the computing module 3000 through the HID driver, and as described in the above-mentioned [Background technology of the invention] and the description of FIG. 1, the HID driver Because it transmits input information directly to the OS, it is impossible to change or process the input information according to the designer's intention.

In other words, the inventor of the present invention connects the electronic whiteboard 1000 with a USB driver to solve the structural limitations of the prior art. It is preferable that a file that allows the electronic whiteboard 1000 to be connected to the USB driver is already stored in the electronic whiteboard 1000 and the computing module 3000.

Unlike the HID driver, the USB driver does not process separate input information, but can simply receive information from the device and then transmit it to another component (in the present invention, the bridge module unit 3300). In other words, through this configuration, the present invention has a technical feature of being able to process the input coordinate information as intended by the designer before delivering the writing program, and even if a plurality of coordinate information is generated in the electronic whiteboard 1000, This can be processed independently in the computing module 3000 according to the designer's intention.

Additionally, touch pen information generated by the touch pen 2000 is transmitted to the touch pen information receiver 3200. The touch pen information is preferably transmitted through wireless communication, and more preferably through Bluetooth communication. In other words, the touch pen information transmitting unit 2400 includes a Bluetooth communication module (not shown), and the touch pen information receiving unit 3200 includes a Bluetooth communication module (not shown) and a Bluetooth device driver. The Bluetooth device driver supports Bluetooth communication between the operating system of the computing module 3000 and the touch pen 2000, and transmits received touch pen information to the bridge module unit 3300.

Meanwhile, the touch pen 2000 of the present invention is not recognized as a pen class by the computing module 3000. More specifically, in the prior art shown in FIG. 1, even if a plurality of touch pens are connected to a computing module, each of the plurality of touch pens is recognized as a pen class and connected, and this corresponds to a configuration automatically set in the Windows OS. That is, in this prior art, as described above, when multiple inputs come from the same class, only one input is processed.

However, in the case of the present invention, each of the plurality of touch pens 2000 is not recognized and connected as a pen class, but can be connected to the computing module 30000 as a general Bluetooth device. Because of this, even if a plurality of inputs are input to the computing module 3000 at the same time, the computing module 3000 can achieve the effect of processing the plurality of inputs simultaneously and independently.

Figure 6 schematically shows a process of receiving a plurality of touch pen information from a plurality of touch pens 2000 according to an embodiment of the present invention.

As shown in FIG. 6, when receiving a plurality of touch pen information including different pen identification information, the touch pen information receiver 3200 generates a Bluetooth device driver corresponding to each of the plurality of touch pen information. And, the bridge module unit 3300 independently processes touch pen information received from each of the plurality of Bluetooth device drivers.

Briefly, a technical feature of the computing module 3000 of the present invention is that it is capable of individual communication with each of a plurality of touch pens 2000.

Specifically, N (N is a natural number greater than or equal to 1) touch pens 2000 may be paired with the computing module 3000, and at this time, the computing module 3000 receives a pairing request from each of the N touch pens 2000. When receiving, the touch pen information receiving unit 3200 is requested to create N Bluetooth device drivers. Referring to the description of FIG. 5, the computing module 3000 may receive touch pen information including different information from each of the paired touch pens 2000 through each Bluetooth device driver.

Each touch pen information received through different Bluetooth device drivers includes unique identification information of the touch pen 2000 that transmitted the information. That is, since each of the touch pen information includes different pen identification information, the bridge module unit 3300 of the present invention determines which touch pen 2000 transmitted the corresponding touch pen information according to each pen identification information. can be identified. Referring to FIG. 8, when multiple inputs are input to the computing module 3000 through the electronic whiteboard 1000 and a plurality of touch pens 2000, the received coordinate information and touch pen information are matched according to a preset rule. This can be done, and a more detailed description of this will be provided later in the description of FIGS. 7 and 8.

Figure 7 schematically shows a process of independently processing information received from a plurality of touch pens 2000 according to an embodiment of the present invention, and Figure 8 shows processing of a plurality of inputs according to an embodiment of the present invention. The process is schematically shown.

As shown in FIG. 7, the bridge module unit 3300 receives coordinate information from the coordinate information receiver 3100, receives touch pen information from the touch pen information receiver 3200, and receives touch pen information. And, based on the time at which the coordinate information was received, writing information for the touch pen 2000 is generated by matching the touch pen information and the coordinate information and transmitted to the HID driver unit 3400.

In addition, as shown in FIG. 8, when receiving a plurality of coordinate information and a plurality of touch pen information, the bridge module unit 3300 receives the pen identification information and pen information included in each of the plurality of touch pen information. A plurality of writing information is generated based on a set rule, and the preset rule may be determined based on the time order of receiving the touch pen information and the time order of receiving the coordinate information, as an embodiment of the present invention. there is.

Schematically, Figure 7 shows that three pieces of coordinate information (coordinate information #1 to #3) are transmitted from the coordinate information receiver 3100 through three touch pens 2000, and three pieces of coordinate information (coordinate information #1 to #3) are transmitted from each of the three touch pens 2000. An example in which touch pen information (touch pen information #1 to #3) is transmitted is shown. Additionally, Figure 8 shows an embodiment in which two touch pen information and coordinate information are received. Meanwhile, the present invention is not limited to this embodiment, and fewer or more inputs may be input.

Specifically, as shown in FIG. 7, the bridge module unit 3300 receives each coordinate information (coordinate information #1 to #3) and each touch pen information (touch pen information #1 to #3). Generate writing information by matching. Meanwhile, since the coordinate information corresponds to a coordinate information stream input in real time from the coordinate information transmitter 1500, the coordinate information receiver 3100 cannot know by which touch pen 2000 the coordinate information was input. . Accordingly, the coordinate information receiving unit 3100 transmits the input coordinate information as is to the bridge module unit 3300.

The bridge module unit 3300 matches the coordinate information received from the coordinate information receiver 3100 with the touch pen information received from the touch pen information receiver 3200 to generate writing information of the corresponding touch pen 2000. . The three writing information (writing information #1 to #3) generated by the bridge module unit 3300 are generated according to different pen identification information, and can be distinguished at the HID driver unit 3400 and application program level. , As a result, input by each of touch pens #1 to #3 can be processed independently.

For example, when user #1 writes on the electronic whiteboard 1000 with touch pen #1 (2000.1), the application program stored in the computing module 3000 uses the writing information generated in the bridge module unit 3300. Based on #1, graphics related to writing can be displayed on the display panel 1100, and when user #3 writes on the electronic whiteboard 1000 with touch pen #3 (2000.3), the application program 3500 Can display graphics related to writing on the display panel 1100 based on writing information #3 generated in the bridge module unit 3300. The technical feature of the present invention is that in this embodiment, graphics related to writing based on writing information #1 and graphics related to writing based on writing information #3 can be displayed simultaneously on one display panel 1100. do.

More specifically, the bridge module unit 3300 may match touch pen information and coordinate information according to preset rules, referring to FIG. 8 . Figure 8 shows a process of matching a plurality of touch pen information and a plurality of coordinate information in the bridge module unit 3300. As shown in FIG. 8, coordinate information can be continuously received for a certain period of time. That is, while the user is writing on the electronic whiteboard 1000, the electronic whiteboard 1000 can transmit coordinate information about the position where the user is writing in real time to the bridge module unit 3300 through a USB driver.

Meanwhile, as described above in the description of FIG. 3, when pressure is sensed by the pressure sensor 2100 of the touch pen 2000, the touch pen 2000 generates touch pen information of the touch pen 2000. It is transmitted to the touch pen information receiver (3200). At this time, the bridge module unit 3300 can receive touch pen information and coordinate information almost simultaneously. That is, since the touch pen information corresponding to the coordinate information is received within a predetermined time from the point of receiving the coordinate information, the bridge module unit 3300 can generate writing information by matching the coordinate information and the touch pen information. there is.

As shown in FIG. 8, when coordinate information #1 is being received and touch pen information #1 is received, the bridge module unit 3300 matches coordinate information #1 and touch pen information #1 to generate writing information. When #1 is generated and coordinate information #2 is being received, when touch pen information #2 is received, the bridge module unit 3300 matches coordinate information #2 and touch pen information #2 to generate writing information #2. Create.

At this time, in the time interval T1 to T2, when touch pen information #2 is being received, coordinate information #1 and coordinate information #2 are received at the same time, but the bridge module unit 3300 touches coordinate information #1 from the front. Since it is matched with pen information #1, touch pen information #2 is matched with coordinate information #2, not coordinate information #1.

That is, through the above configuration, even if user #2 writes additionally on the electronic whiteboard 1000 with another touch pen 2000 while user #1 is writing on the electronic whiteboard 1000, the bridge module Different writing information is generated by processing different touch pen information and coordinate information for #1 (2000.1) and touch pen #2 (2000.2), so User #1 and User #2 can work independently without interference with writing style, etc. Writing can be performed on one electronic whiteboard (1000).

Additionally, as shown in FIG. 8, coordinate information is continuously received during a specific time period in the bridge module unit 3300, while touch pen information is received and then periodically received when matched with coordinate information, or It can be received only when touch pen information (for example, handwriting style information) is changed by the user.

As an embodiment of the present invention, the bridge module unit 3300 stores coordinate information in the order of input coordinate information, and matches each touch pen information and coordinate information according to the order of input coordinate information and touch pen information. You can do it.

For example, when the bridge module unit 3300 receives coordinate information a total of 4 times, the order is assigned to coordinate information #1 to #4 according to the order in which they are received (actually assigned on the computing module 3000) (It is described to distinguish different coordinate information), Accordingly, the received touch pen information is received in the order of touch pen information #3, touch pen information #1, touch pen information #2, and touch pen information #3. When this happens, the bridge module unit 3300 generates writing information after matching coordinate information #1 and touch pen information #3, and generates writing information after matching coordinate information #2 and touch pen information #1, Writing information is created after matching coordinate information #3 and touch pen information #2, and writing information is created after matching coordinate information #4 and touch pen information #3. This example corresponds to a case where touch pen #3 (2000.3) pauses while writing and then resumes writing.

As a result, the present invention provides the coordinate information generated by the electronic whiteboard 1000 through the computing module 3000 and a plurality of touch pens 2000 even if the touch pen 2000 does not communicate with the electronic whiteboard 1000. By matching the touch pen information generated from each, it is possible to create multiple writing information that can be distinguished at the application level.

Figure 9 schematically shows the process of transferring information generated in the bridge module unit 3300 to the writing program operating unit according to an embodiment of the present invention.

As shown in FIG. 9, the bridge module unit 3300 generates writing information for the corresponding touch pen 2000 by matching the touch pen information and coordinate information based on the time at which the touch pen information and coordinate information were received. This is transmitted to the HID driver unit 3400, and the HID driver unit 3400 receives writing information for each touch pen 2000 and sends it to an application program running on the operating system installed on the computing module 3000. Compatible input information is generated, and the application program stored in the computing module 3000 operates according to the input information received from the HID driver unit 3400.

Schematically, Figure 9 shows the process in which a plurality of writing information (writing information #1 to #3) generated in the bridge module unit 3300 is transmitted to the application operation unit 3500 through the HID driver unit 3400. do.

Specifically, referring to the description of FIG. 1, the HID driver unit 3400 includes an HID driver. The HID driver is a configuration provided by the OS installed in the computing module 3000, and more specifically, it is a device class definition that supports HID devices such as keyboard, mouse, game controller, etc. In other words, HID refers to a standard for human-operated computer equipment, and the HID driver functions to add support for hardware innovations through an extensible, standardized, and easily programmable interface on the OS. By using these standards, various devices connected to computers, etc. have the advantage of being able to be used without additional software or separate drivers.

However, in the case of the electronic whiteboard 1000 of the prior art, when the electronic whiteboard 1000 and the computing module 3000 are connected, the information from the electronic whiteboard 1000 is automatically transmitted directly to the OS through the HID driver. Because of this, completely independent multitouch could not be supported. Meanwhile, in the case of the present invention, a separate configuration is added between the electronic whiteboard 1000 and the HID driver unit 3400 through the configuration described above in FIGS. 2 to 8 to enable multi-touch input through a plurality of touch pens 2000. Can support touch.

As shown in FIG. 9, when writing information generated in the bridge module unit 3300 is transmitted to the HID driver unit 3400, the HID driver unit 3400 generates input information based on the received writing information. A plurality of input information can be distinguished by the HID driver unit 3400 and an application program through the pen identification information included in the writing information used when generating the input information, and the application program can be divided into a plurality of programs based on the input information. Different styles of writing functions can be provided for input by the touch pen 2000, and a plurality of people can write on the electronic whiteboard 1000 at the same time.
