[0052] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0053] Example 1

[0054] Reference Figure 1 As shown, Figure 1 A flowchart of the first method of the interactive teaching method provided in the embodiments of this application.

[0055] The method includes the following steps:

[0056] S101, monitor the level signal of the photoelectric sensor array on the tool wall in real time, generate a transition edge in response to the level signal of the photoelectric sensor array, and determine the target tool or target gauge based on the transition edge of the level signal;

[0057] The interactive teaching method proposed in this application monitors the voltage level of the photoelectric sensor array on the tool wall in real time to detect whether the signal generates a transition edge signal, such as the output signal of a photoelectric sensor changing from high to low (falling edge) or from low to high (rising edge). If the voltage level of a photoelectric sensor generates a transition edge signal, the target tool or measuring instrument on the tool wall can be identified based on this transition edge. For example, if a vernier caliper is placed at a preset position on the tool wall, when the user removes the caliper, the photoelectric sensor in the corresponding photoelectric sensor array at that position will generate a transition edge signal. The change in the voltage level of the photoelectric sensor can then be used to determine that the target measuring instrument removed by the user is the vernier caliper. If the voltage level of the photoelectric sensor array does not change, it indicates that the tool on the tool wall has not been removed by the user, and no operation has been performed.

[0058] S102, determine the target video corresponding to the target tool or target measuring tool from the video resources according to the target tool or target measuring tool;

[0059] Once the target tool or gauge is determined based on the transition edge of the level signal, the target video corresponding to the target tool or gauge can be acquired for playback. At the same time, the target video provides the user with operational information related to the target tool or gauge.

[0060] S103, Play the target video and use the target video to prompt the operation information of the target tool or target measuring instrument.

[0061] After identifying the target video corresponding to the target tool or measuring instrument from the video resources, the target video can be played through the corresponding device. The target video stores operation information related to the target tool or measuring instrument, including product introduction and detailed operation steps demonstration.

[0062] The interactive teaching method of this application monitors the level signal of the photoelectric sensor array on the tool wall in real time. When a user removes any target tool or measuring instrument from the tool wall (the ones on the tool wall are called target tools or measuring instruments, and the ones removed by the user are called target tools or measuring instruments), the level signal of the photoelectric sensor corresponding to the target tool or measuring instrument in the corresponding photoelectric sensor array will change, that is, a rising edge will be generated. Based on the rising edge of the level signal, the specific target tool or measuring instrument can be determined, and then the target video corresponding to the target tool or measuring instrument can be played. Therefore, when a user removes any target tool or measuring instrument from the tool wall, the video corresponding to the target tool or measuring instrument can be played, realizing interactive teaching between video teaching and the user's removal and placement of target tools or measuring instruments from the tool wall, improving students' cognitive ability and learning effect.

[0063] In one embodiment, before the level signal of the photoelectric sensor array on the real-time monitoring tool wall, it further includes:

[0064] Determine the location of the target tool or target measuring instrument on the tool wall, and determine the video resources corresponding to the target tool or target measuring instrument;

[0065] Specifically, to determine the specific target tool or gauge that the user takes from the tool wall, it is necessary to determine the location of the target tool or gauge on the tool wall. In addition, it is necessary to determine the video resources corresponding to the target tool or gauge, so as to establish the correspondence between the target tool or gauge, the location of the target tool or gauge on the tool wall, and the video resources.

[0066] Establish a correspondence between the target tool or gauge and its position on the tool wall, and establish a correspondence between the target tool or gauge and the video resource.

[0067] Specifically, to determine the specific target tool or measuring instrument that a user removes from the tool wall, it is necessary to establish a correspondence between the target tool or measuring instrument (including its type and model) and its position on the tool wall, as well as a correspondence between the target tool or measuring instrument and video resources. Specifically, when a user removes any target tool or measuring instrument from the tool wall, the target position of the target tool or measuring instrument on the tool wall can be determined using a photoelectric sensor array. Since the correspondence between the target tool or measuring instrument's position on the tool wall and the target tool or measuring instrument itself is established beforehand, determining the target position of the target tool or measuring instrument on the tool wall using the photoelectric sensor array determines the specific target tool or measuring instrument (such as a vernier caliper, wrench, etc., down to the specific model of the vernier caliper or wrench). Because the correspondence between the target tool or measuring instrument and video resources is established beforehand, once the target tool or measuring instrument is determined, the corresponding target video can be determined.

[0068] In one embodiment, determining the target tool or target gauge based on the transition edge of the level signal includes:

[0069] The position of the target tool or target gauge on the tool wall is determined based on the rising edge of the level signal;

[0070] Specifically, when the level signal of the photoelectric sensor array generates a rising edge, that is, when the level signal of some photoelectric sensors in the photoelectric sensor array generates a rising edge, the position of the photoelectric sensor that generated the rising edge signal in the photoelectric sensor array can be determined. The position of the photoelectric sensor that generated the rising edge signal in the photoelectric sensor array is the position of the target tool or target gauge that the user has taken down in the photoelectric sensor array, thus determining the target position of the target tool or target gauge on the tool wall.

[0071] The target tool or target gauge is determined based on its position on the tool wall.

[0072] Specifically, since a correspondence has been established in advance between the location of the target tool or gauge on the tool wall and the target tool or gauge itself, once the target location of the target tool or gauge on the tool wall is determined by the photoelectric sensor array, the specific target tool or gauge that the user takes off from the tool wall is determined.

[0073] In one embodiment, determining the target video corresponding to the target tool or target gauge from the video resources based on the target tool or target gauge includes:

[0074] The level signal of the photoelectric sensor array on the tool wall is monitored in real time, and the real-time area of ​​the target tool or target gauge on the tool wall is determined based on the level signal of the photoelectric sensor array.

[0075] Specifically, in order to further enhance interactivity and improve teaching effectiveness, the interactive teaching method of this application can also determine the real-time area of ​​the target tool or target measuring instrument on the tool wall by real-time monitoring of the level signal of the photoelectric sensor array on the tool wall. That is, the user can directly operate and learn on the target tool or target measuring instrument on the tool wall. For example, the user can directly move the vernier caliper (the teeth of the vernier caliper are fixed on the tool wall, and the vernier scale can move) on the tool wall to make measurements. At this time, the vernier scale of the vernier caliper moved by the user can be monitored in real time to the specific position it has moved to.

[0076] In response to a change in the real-time region, a target video segment is determined from the target video based on the real-time region.

[0077] Specifically, the system monitors the level signal of the photoelectric sensor array on the tool wall in real time. If the level signal of the photoelectric sensor array on the tool wall changes, it indicates that the user has removed the target tool or measuring instrument from the tool wall. If the level signal of the photoelectric sensor array on the tool wall changes and the real-time area of ​​the target tool or measuring instrument on the tool wall changes, it indicates that the user has directly operated on the target tool or measuring instrument on the tool wall. The target video segment can then be determined from the target video based on the real-time area of ​​the target tool or measuring instrument on the tool wall.

[0078] In one embodiment, before determining the target video segment from the target video based on the real-time region, the method further includes:

[0079] Based on the operation steps of the target tool or target measuring instrument, a number of interactive positions corresponding to the target tool or target measuring instrument are determined, and the number of interactive positions form a number of preset areas with logical relationships.

[0080] Specifically, before determining the target video segment from the target video based on the real-time area, it is necessary to first determine several interactive positions corresponding to the target tool or measuring instrument based on the operation steps of the target tool or measuring instrument. These interactive positions form several preset areas with logical relationships. For example, taking a vernier caliper as an example, when a user operates the vernier caliper for practical measurement, the following steps are required: First, move the vernier scale of the vernier caliper from the initial position (zero scale position) to an interactive position; second, tighten the locking screw to fix the vernier scale on the gear body; third, take the reading; fourth, move the vernier scale to the next interactive position to continue taking the reading or move the vernier scale back to the initial position to end the operation. Therefore, the initial zero scale position of the vernier caliper is the initial area. In addition, one or more interactive areas are set for user interaction; that is, the vernier scale of the vernier caliper moves to one or more interactive positions, and different interactive positions are all considered interactive areas. The initial position and several interactive areas are all preset areas. In this system, following the user's operating steps, the target tool or measuring instrument is located in the initial area when the user has not yet started moving. When the user begins moving, the target tool or measuring instrument is located in the next preset area. If the user finishes the measurement practice, the target tool or measuring instrument is moved back to the initial area; if the user continues the practice, the target tool or measuring instrument is moved to the next preset area. Therefore, the logical relationship is based on the order of several preset areas divided according to the operating steps of the target tool or measuring instrument. For example, the preset logical relationship for a vernier caliper might be initial area, first preset area, second preset area, and initial area again, etc., specifically set according to actual needs.

[0081] The target video is divided into several sub-videos according to the operation steps of the target tool or target measuring instrument.

[0082] Specifically, based on the user's operating steps with the vernier caliper, to enhance interactivity, a corresponding video prompts the user for each step. For example, when the user moves the vernier caliper's vernier scale, the video prompts the user to move it to a preset area. During this movement, the position of the vernier scale can be monitored using a photoelectric sensor array, or other devices can be used to improve monitoring accuracy. A corresponding indicator light will also indicate to the user that the vernier scale has been moved to the preset area. Therefore, the target video is a complete video prompting the user's operation, including all operating steps, such as prompting the user to move the vernier scale from the initial area to the preset area, prompting the user to tighten the locking screw, prompting the user on how to read the value, and prompting the user to move the vernier scale to the initial position or the next preset area. Therefore, the target video is divided into several sub-videos according to the operating steps of the target tool or measuring instrument, with each operating step corresponding to one sub-video.

[0083] Establish the correspondence between the sub-video and the preset region;

[0084] Specifically, each operation step of the user on the target tool or target measuring instrument corresponds to a sub-video. Therefore, a correspondence is established between each sub-video and each operation step. Each operation step corresponds to the position that the target tool or target measuring instrument moves to, which is the preset area it moves to. Therefore, a correspondence is established between sub-videos and preset areas, with one sub-video corresponding to one preset area.

[0085] In one implementation, determining the target video segment from the target video based on the real-time region includes:

[0086] In response to the real-time region coinciding with any of the preset regions, the preset region coinciding with the implementation region is determined as the target region;

[0087] Specifically, when a user moves the vernier caliper and the real-time area of ​​the vernier caliper coincides with the preset area, it means that the user has moved the vernier caliper to the interactive position. The user is then prompted to perform the operation steps at the interactive position. The preset area that coincides with the real-time area needs to be identified as the target area so that the corresponding prompt video can be determined based on the target area.

[0088] Based on the target region, determine the target sub-video corresponding to the target region from the plurality of sub-videos;

[0089] Specifically, since a correspondence between sub-videos and preset regions has already been established, once the target region is determined, the sub-videos corresponding to the target region can be determined based on the correspondence between sub-videos and preset regions. These sub-videos are called target sub-videos.

[0090] The downstream video of the target sub-video is determined according to the logical relationship, and the downstream video is used as the target video segment to be played.

[0091] Specifically, when a user moves the vernier caliper towards a preset area, and the real-time area of ​​the vernier caliper coincides with any preset area (i.e., when the vernier caliper moves to the preset area), the user should be prompted to tighten the locking screw as the next step. Therefore, after determining the target sub-video, the downstream video of the target sub-video is determined, that is, the next sub-video determined according to the logical relationship. For example, the target sub-video might be prompting the user on how to move the vernier caliper (when the user does not move the vernier caliper, a default video is played, such as displaying an image of the vernier caliper; that is, the video corresponding to the initial area is the default video). When a change in the real-time area of ​​the vernier caliper is detected, a video showing the movement of the vernier caliper to the preset area is played. The target sub-video corresponding to the preset area is the video showing the movement of the vernier caliper to that preset area. Therefore, when the vernier caliper is detected to have moved to the preset area, the video that needs to be prompted is the next video (downstream video) corresponding to the video of the preset area, which is the video prompting the user to tighten the locking screw, that is, the next sub-video of the target sub-video determined according to the logical relationship.

[0092] In one embodiment, playing the target video and providing operational information about the target tool or measuring instrument through the target video includes:

[0093] The target video clip is played through the terminal, and the operation steps, product information, or precautions of the target tool or measuring instrument are displayed through the target video clip.

[0094] Specifically, once the target video is selected, its content can be played. When the user directly removes the target tool or measuring instrument from the tool wall, the complete video corresponding to that tool or instrument is played. When the user directly operates on the target tool or measuring instrument on the tool wall, a video segment related to the operation steps is played. These video segments are breakdowns of the complete video. Furthermore, product information or precautions for the target tool or measuring instrument can be played, depending on specific needs.

[0098] To determine the specific target tool or gauge that the user has taken from the tool wall, it is necessary to first determine the location of the target tool or gauge on the tool wall. In addition, it is necessary to determine the video resources corresponding to the target tool or gauge, so as to establish the correspondence between the target tool or gauge, the location of the target tool or gauge on the tool wall, and the video resources.

[0099] S202, establish the correspondence between the target tool or target measuring instrument and its position on the tool wall, and establish the correspondence between the target tool or target measuring instrument and the video resource;

[0100] To determine the specific target tool or measuring instrument that a user takes from the tool wall, it is necessary to first establish the correspondence between the target tool or measuring instrument and its position on the tool wall, as well as the correspondence between the target tool or measuring instrument and the video resources.

[0101] S203, monitor the level signal of the photoelectric sensor array on the tool wall in real time, and determine whether the level signal of the photoelectric sensor array generates a transition edge;

[0102] The system monitors the level signal of the photoelectric sensor array on the tool wall in real time and determines whether the level signal of the photoelectric sensor array generates a transition edge. If the level signal of the photoelectric sensor array generates a transition edge, then step S204 is executed: the position of the target tool or target gauge on the tool wall is determined based on the transition edge of the level signal; if the level signal of the photoelectric sensor array does not generate a transition edge, then the system continues to monitor the level signal of the photoelectric sensor array on the tool wall.

[0103] S204, determine the position of the target tool or target gauge on the tool wall based on the rising edge of the level signal;

[0104] When the level signal of the photoelectric sensor array generates a rising edge, that is, when the level signal of some photoelectric sensors in the photoelectric sensor array generates a rising edge, the position of the photoelectric sensor that generates the rising edge signal in the photoelectric sensor array can be determined. The position of the photoelectric sensor that generates the rising edge signal in the photoelectric sensor array is the position of the target tool or target gauge that the user has taken down in the photoelectric sensor array, thus determining the target position of the target tool or target gauge on the tool wall.

[0105] S205, determine the target tool or target gauge based on its position on the tool wall;

[0106] Since a pre-established correspondence between the location of the target tool or gauge on the tool wall and the target tool or gauge itself is established, once the target location of the target tool or gauge on the tool wall is determined based on the photoelectric sensor array, the specific target tool or gauge that the user removes from the tool wall is determined.

[0107] S206, determine the target video corresponding to the target tool or target measuring instrument from the video resources according to the target tool or target measuring instrument;

[0108] Once the target tool or gauge is determined based on the transition edge of the level signal, the target video corresponding to the target tool or gauge can be acquired for playback. At the same time, the target video provides the user with operational information related to the target tool or gauge.

[0110] After identifying the target video corresponding to the target tool or measuring instrument from the video resources, the target video can be played through the corresponding device. The target video stores operation information related to the target tool or measuring instrument, including product introduction and detailed operation steps demonstration.

[0113] S301, determine the position of the target tool or target measuring instrument on the tool wall, and determine the video resource corresponding to the target tool or target measuring instrument;

[0114] To determine the specific target tool or gauge that the user has taken from the tool wall, it is necessary to first determine the location of the target tool or gauge on the tool wall. In addition, it is necessary to determine the video resources corresponding to the target tool or gauge, so as to establish the correspondence between the target tool or gauge, the location of the target tool or gauge on the tool wall, and the video resources.

[0115] S302, establish the correspondence between the target tool or target measuring instrument and its position on the tool wall, and establish the correspondence between the target tool or target measuring instrument and the video resource;

[0116] S303, determine a number of interactive positions corresponding to the target tool or target measuring instrument according to the operation steps of the target tool or target measuring instrument, and the number of interactive positions form a number of preset areas with logical relationships;

[0117] S304, the target video is divided into several sub-videos according to the operation steps of the target tool or target measuring instrument;

[0118] S305, Establish the correspondence between the sub-video and the preset region;

[0119] The system monitors the level signal of the photoelectric sensor array on the tool wall in real time, generates a transition edge in response to the level signal of the photoelectric sensor array, and determines the target tool or target gauge based on the transition edge of the level signal.

[0120] S306, determine whether the level signal of the photoelectric sensor array generates a transition edge.

[0121] If the level signal of the photoelectric sensor array generates a transition edge, then step S307 is executed: determine the position of the target tool or target gauge on the tool wall based on the transition edge of the level signal; if the level signal of the photoelectric sensor array does not generate a transition edge, then continue to monitor the level signal of the photoelectric sensor array on the tool wall in real time.

[0122] S307, determine the position of the target tool or target gauge on the tool wall based on the rising edge of the level signal;

[0123] When the level signal of the photoelectric sensor array generates a rising edge, that is, when the level signal of some photoelectric sensors in the photoelectric sensor array generates a rising edge, the position of the photoelectric sensor that generates the rising edge signal in the photoelectric sensor array can be determined. The position of the photoelectric sensor that generates the rising edge signal in the photoelectric sensor array is the position of the target tool or target gauge that the user has taken down in the photoelectric sensor array, thus determining the target position of the target tool or target gauge on the tool wall.

[0124] S308, determine the target tool or target gauge based on the rising edge of the level signal;

[0125] Since a pre-established correspondence between the location of the target tool or gauge on the tool wall and the target tool or gauge itself is established, once the target location of the target tool or gauge on the tool wall is determined based on the photoelectric sensor array, the specific target tool or gauge that the user removes from the tool wall is determined.

[0126] S309, determine whether the real-time area of ​​the target tool or target gauge located on the tool wall has changed.

[0127] If the real-time area changes, it means the user is directly measuring the target tool or gauge on the tool wall. In this case, step S310 is executed: determine whether the real-time area overlaps with any preset area. If the real-time area does not change, it means the user is directly removing the target tool or gauge from the tool wall. In this case, step S311 is executed: determine the target video corresponding to the target tool or gauge from the video resources, and then step S312 is executed: play the target video and provide operation information for the target tool or gauge through the target video.

[0128] S310, determine whether the real-time area overlaps with any preset area;

[0129] If the real-time area coincides with any preset area, it means that the user is directly practicing measuring the target tool or gauge on the tool wall, and the user moves the target tool or gauge to the interactive position. Then, step S313 is executed: determine the preset area that coincides with the implementation area as the target area; if the real-time area does not coincide with any preset area, wait for the user to move the target tool or gauge (such as the vernier scale of a vernier caliper) to the preset area (interactive position).

[0130] S311, determine the target video corresponding to the target tool or target measuring instrument from the video resources according to the target tool or target measuring instrument;

[0131] Once the target tool or gauge is determined based on the transition edge of the level signal, the target video corresponding to the target tool or gauge can be acquired for playback. At the same time, the target video provides the user with operational information related to the target tool or gauge.

[0132] S312, Play the target video and use the target video to prompt the operation information of the target tool or target measuring instrument.

[0133] After identifying the target video corresponding to the target tool or measuring instrument from the video resources, the target video can be played through the corresponding device. The target video stores operation information related to the target tool or measuring instrument, including product introduction and detailed operation steps demonstration.

[0134] S313, determine the preset area that overlaps with the real-time area as the target area;

[0135] When a user moves the vernier caliper and the real-time area of ​​the vernier caliper coincides with the preset area, it means that the user has moved the vernier caliper to the interactive position. The user will then be prompted to perform the operation steps at the interactive position. The preset area that coincides with the real-time area needs to be identified as the target area so that the corresponding prompt video can be determined based on the target area.

[0136] S314, determine the target sub-video corresponding to the target region from the plurality of sub-videos based on the target region;

[0137] Since a correspondence between sub-videos and preset regions has already been established, once the target region is determined, the sub-videos corresponding to the target region can be determined based on the correspondence between sub-videos and preset regions. These sub-videos are called target sub-videos.

[0138] S315, determine the downstream video of the target sub-video according to the logical relationship, and use the downstream video as the target video segment to be played;

[0139] For example, when the user moves the vernier ruler towards a preset area, and the real-time area of ​​the vernier ruler coincides with any preset area—that is, when the vernier ruler moves to the preset area—the user should be prompted to proceed to the next step of tightening the locking screw. Therefore, after determining the target sub-video, the downstream video of the target sub-video is then determined; that is, the next sub-video determined according to the logical relationship is identified, and the downstream video is used as the target video segment to be played.

[0140] S316, Play the target video clip through the terminal and use the target video clip to prompt the target tool or target measuring instrument with operation steps, product information or precautions.

[0141] Once the target video is selected, its content can be played. When the user directly removes the target tool or measuring instrument from the tool wall, the complete video corresponding to that tool or instrument will be played. When the user directly operates on the target tool or measuring instrument on the tool wall, a video segment related to the operation steps will be played. These video segments are split videos from the complete video. Additionally, product information or precautions for the target tool or measuring instrument can be played, depending on specific needs.

[0142] It should be understood that, although Figures 1-3 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figures 1-3 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0143] Example 4

[0144] Reference Figure 4 As shown, Figure 4 This is a schematic diagram of the structure of the interactive teaching system provided in the embodiments of this application.

[0145] The interactive teaching system of this embodiment includes:

[0146] Tool wall 1, used to set up several target tools or target gauges and photoelectric sensor array 2;

[0147] like Figure 4 As shown, the interactive teaching system includes a tool wall 1, which is used to hang several target tools or measuring instruments, such as wrenches, vernier calipers, etc. Figure 4 The area marked by the dashed line indicates the location for mounting the target tool or gauge. Furthermore, the photoelectric sensor array 2 is mounted on the tool wall 1. The tool wall 1 can be a perforated board or similar device for easily mounting the target tool or gauge, and can also be equipped with hooks for this purpose. Moreover, each tool wall can have corresponding EVA contour holes, allowing users to easily return the target tool or gauge to its original location after use. Additionally, since different target tools or gauges have different shapes, the EVA contour holes can be used to determine which target tool or gauge the user has removed.

[0148] The photoelectric sensor array 2 is used to detect the target tools or target measuring instruments on the tool wall 1;

[0149] The interactive teaching system also includes a photoelectric sensor array 2, mounted on the tool wall 1, used to detect target tools or gauges on the tool rack based on electrical level signals. Several photoelectric sensors form the sensor array 2, such as... Figure 4 As shown, photoelectric sensors can be installed at the desired locations on tool wall 1, or they can be installed on the entire tool wall 1. The photoelectric sensors are infrared diffuse reflection sensors, powered by DC 5-30V, with a maximum detection distance of 70mm. Therefore, the distance between the target tool or gauge and the photoelectric sensor array 2 must be less than 70mm. The photoelectric sensors can be directly mounted on a perforated board, or mounted on tool wall 1 using appropriate mounting tools, as long as it does not affect the photoelectric sensors' detection of the target tool or gauge.

[0150] The smart board 3 is used to receive the level signal of the photoelectric sensor array 2 and send the level signal to the terminal 5.

[0151] The interactive teaching system also includes a smart board 3. The smart board 3 uses a DC24V (AC230V to DC24V switching power supply, 75W power, providing DC power for the interactive teaching system) input power, ensuring high safety. The smart board 3 communicates with the photoelectric sensor array 2 to receive the level signals from the photoelectric sensor array 2. Furthermore, the smart board 3 has an RJ45 network port. After reading the level signals from the photoelectric sensors, the smart board 3 can send the signals to the router 4 via the RJ45 network port, and then the router 4 will send the signals to the terminal 5 (computer or server, etc.). In addition, one smart board 3 is installed for each tool wall 1. Since the router 4 has multiple RJ45 network ports, each of which can connect to one terminal 5, multiple smart boards 3 of tool walls 1 can be connected to the router 4 via their respective RJ45 network ports. That is, the level signals from the photoelectric sensor array 2 of each tool wall 1 can be sent to the router 4, and then the router 4 will transmit them to one or more terminals 5. Router 4 allows for the expansion of several smart boards 3 within the interactive teaching system, offering good scalability. Several interactive teaching systems can be displayed simultaneously, improving teaching quality and effectiveness. Figure 4 The middle section expands to include three tool walls 1.

[0152] Terminal 5 is configured to determine a target tool or target gauge based on the transition edge of the level signal, determine a target video corresponding to the target tool or target gauge from video resources based on the target tool or target gauge, and play the target video and provide operation information of the target tool or target gauge through the target video.

[0153] Terminal 5 can be a desktop computer or a server computer, capable of running software. It can also connect to and drive a display (such as screen 6). After receiving the level signal data from the smart board 3, terminal 5 can parse the data to run educational resources, such as tool education videos (target videos or video clips), through appropriate software. Terminal 5 is connected to screen 6, which displays the tool education resources (video resources). Screen 6 can play product videos, provide tool usage tutorials, and offer audio and text explanations. It can also display the tool's structure in 3D, allowing for comparison and learning with the actual tool.
