Technical Field

[0001] This invention relates to the field of computer communication technology, and more particularly to learning assistance systems. Background Technology

[0002] This section is intended to provide background or context for the embodiments of the invention set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section.

[0003] With the development of science and technology, various learning assistance systems have emerged in the market to enhance students' learning interest. Currently, some learning assistance systems require additional electronic devices, such as tablets or smartphones, for assisted learning, necessitating operation of these devices for interaction. Generally, during the learning process, constant adjustments to the electronic device's status or repeated operation are required to achieve interactive operation, resulting in poor interactivity of the learning assistance system. Furthermore, students cannot detach themselves from tablets or smartphones during assisted learning, potentially wasting time playing with them and neglecting their studies. Additionally, existing learning assistance systems cannot provide real-time guidance and feedback to students' learning, leading to low efficiency in assisting learning.

[0004] Therefore, existing learning assistance systems suffer from poor interactivity and low efficiency in assisting learning. Summary of the Invention

[0007] The scanning module, projection module, and infrared touch module are all connected to the main control module;

[0008] The scanning module sends the scanned learning interface to the main control module, which then sends the learning interface to the online teacher through the auxiliary teaching system. The main control module receives feedback interfaces sent by the online teacher through the auxiliary teaching system and controls the projection module to project the learning interface or feedback interface. The infrared touch module receives touch operations from the user on the projected interface, and the main control module responds to the touch operations fed back by the infrared touch module.

[0009] In this embodiment of the invention, the learning assistance system includes a scanning module, a main control module with an embedded auxiliary teaching system, a projection module, and an infrared touch module. All three modules are connected to the main control module. In this embodiment, the infrared touch module controls the projected interface, eliminating the need for additional electronic devices and improving the interactivity of the learning assistance system. Furthermore, the main control module receives real-time feedback from online teachers on the learning interface and controls the projection module to project the learning interface or feedback interface, allowing for timely guidance and correction of student learning without waiting, thus improving the efficiency of assisted learning.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0021] Figure 1 The module structure of the learning assistance system provided in the first embodiment of the present invention is shown. For ease of description, only the parts related to the embodiment of the present invention are shown, and are described in detail below:

[0022] like Figure 1 As shown, the learning assistance system includes:

[0023] The system comprises a scanning module 101, a main control module 102 with an embedded auxiliary teaching system, a projection module 103, and an infrared touch module 104.

[0024] The scanning module 101, projection module 103, and infrared touch module 104 are all connected to the main control module 102;

[0025] The scanning module 101 sends the scanned learning interface to the main control module 102. The main control module 102 sends the learning interface to the online teacher through the auxiliary teaching system and receives the feedback interface sent by the online teacher through the auxiliary teaching system. The main control module 102 controls the projection module 103 to project the learning interface or feedback interface into a projection interface. The infrared touch module 104 receives the user's touch operation on the projection interface, and the main control module 102 responds to the touch operation fed back by the infrared touch module 104.

[0026] The learning aid system can be connected to a household outlet via a power cord to provide power. Furthermore, to enhance portability and flexibility, the system includes a power module. This power module can be a battery, which provides power to the learning aid system even when disconnected from the power cord, ensuring several hours of portable use without a power cord.

[0027] The scanning module 101 includes a scanning camera that scans the user's learning interface to acquire image or video information of the interface. During assisted learning, the scanning camera transmits the captured image of the learning interface to the main control interface. The main control interface controls the projection module 103 to project the learning interface sent by the scanning module 101. Those skilled in the art will understand that the scanning module 101 can also be any other scanning module besides the aforementioned scanning camera, as long as it has the function of scanning and acquiring image or video information of the learning interface. This embodiment of the invention does not impose any particular limitations on this.

[0028] The auxiliary teaching system embedded in the main control module 102 can utilize the Zoom online classroom system (hereinafter referred to as the Zoom system for ease of description). The Zoom system easily enables multi-person "face-to-face" high-definition audio and video interactive teaching and meetings, quickly establishing a stable communication and collaboration platform; simultaneously, it can capture every facial expression and monitor real-time status. The Zoom system provides a convenient, stable, and lower-cost new form of video teaching / conference, allowing users to enjoy cloud video education / conference services anytime, anywhere—at the office, at home, or while traveling—without needing dedicated equipment; achieving convenient communication and truly realizing "anytime, anywhere" learning / meeting. Although both connect multiple users through video conferencing technology, Zoom is simpler, more stable, and faster, creating a one-stop audio and video interaction and data sharing platform for users. Zoom has the following significant advantages: (1) It supports high-definition audio and video interaction for up to 500 people; (2) No account is required, and you can join the meeting by clicking the meeting URL; (3) It supports meeting recording; (4) It adaptively adjusts network bandwidth; (5) It features intelligent echo cancellation and audio noise reduction; (6) It automatically identifies and loads audio devices; (7) It supports integration with Web / Client / APP applications; and (8) It supports meeting data statistics.

[0029] In addition, the main control module 102 adopts the Rockchip RK3399 six-core 64-bit server-grade chip solution. The RK3399 is a low-power, high-performance application processor chip launched by Rockchip. Based on the Big.Little architecture, it features a dual-core Cortex-A72 and quad-core Cortex-A53 architecture with independent NEON coprocessors. It is primarily used in computers, personal internet mobile devices, VR, digital signage, and other smart terminal devices. The RK3399 integrates multiple high-performance hardware processing engines, supporting various video decoding formats, such as 4K*2K@60fps H.264 / H.265 / VP9, and also supports 1080P@30fps H.264 / MVC / VP8, as well as high-quality JPEG encoding / decoding and image pre- and post-processing. It supports infrared remote control, 2.4GHz / 5GHz dual-band WiFi, Bluetooth 4.1-BLE, PCIe expansion, Type-C, high-speed USB 3.0, and features such as 4G module, gravity sensor, GPS, serial port expansion, I / O port expansion, MIPI camera, and HDMI_IN input. Its rich hardware interfaces make the product more versatile. Due to its hardware platform and Android-based intelligent features, it can be used with a smart terminal platform for human-computer interaction and network device interaction. The main control module 102, using the RK3399, is the core component of the projection computer. It is responsible for processing data collected by other modules and controlling them to perform related operations. Those skilled in the art will understand that the main control module 102 can also use other chips with equivalent functions besides the RK3399 chip; this embodiment of the invention does not impose any particular limitations on this.

[0030] In addition, the main control module 102 is deployed with one or more of the following operating systems: Microsoft operating system, Android operating system, Linux operating system, and Unix operating system. The main control module 102 has multiple applications embedded with the corresponding operating system, and users can also download multiple applications that are compatible with the operating system, such as Windows applications or Android applications, via wireless network.

[0031] The projection module 103 can be connected to the main control module 102 via an HDMI (High Definition Multimedia Interface) cable. The main control module 102 converts the learning interface fed back by the scanning module 101 or the feedback interface received from the online teacher into RGB signals via the HDMI cable. The projection module 103 then uses the projection optical engine driver 403 to form the projection interface from the RGB signals.

[0032] In addition, while projection is in progress, the user can perform touch operations on the projection interface. The infrared touch module 104 receives the user's touch operations on the projection interface and feeds back the user's touch operations to the main control module 102. The main control module 102 responds to the touch operations fed back by the infrared touch module 104. The infrared touch module 104 can be a micro-projector touch autofocus module (LT1PH4-B-2). Those skilled in the art will understand that the infrared touch module 104 can also use other infrared touch devices besides the aforementioned micro-projector touch autofocus module (LT1PH4-B-2), and this embodiment of the invention does not impose any particular limitations on this.

[0033] In this embodiment of the invention, the learning assistance system includes a scanning module 101, a main control module 102 with an embedded auxiliary teaching system, a projection module 103, and an infrared touch module 104. The scanning module 101, projection module 103, and infrared touch module 104 are all connected to the main control module 102. In this embodiment, the infrared touch module 104 controls the projected interface, enabling touch operation without additional electronic devices, thus improving the interactivity of the learning assistance system. Furthermore, the main control module 102 receives real-time feedback from online teachers on the learning interface and controls the projection module 103 to project the learning interface or feedback interface, allowing for timely guidance and correction of student learning without waiting, thereby improving the efficiency of assisted learning.

[0034] Figure 2 The module structure of the learning assistance system provided in the second embodiment of the present invention is shown. For ease of description, only the parts related to the embodiments of the present invention are shown, and are described in detail below:

[0035] In one embodiment of the present invention, in order to monitor students' learning in a timely manner and further improve the learning efficiency of the learning assistance system, such as... Figure 2 As shown, based on the above module structure, the learning assistance system also includes a face recognition module 201 connected to the main control module 102.

[0036] The face recognition module 201 performs face recognition on the user. After the face recognition is successful, the main control module 102 controls the projection module 103 to project the learning interface onto the projected interface.

[0037] The face recognition module 201 may include a face recognition camera. The face recognition camera recognizes captured facial images and sends the recognition result to the main control module 102. The main control module 102 determines whether to perform assisted learning based on the recognition result. For example, if face recognition is successful, the main control module 102 controls the projection module 103 to project the learning interface, displaying messages such as "Welcome XXX, wish you a pleasant learning experience" when the projection interface starts; if face recognition fails, the main control module 102 automatically closes the online class and displays messages such as "You do not have permission to view, please grant XXX permissions" on the projection interface.

[0038] In this embodiment of the invention, the face recognition module 201 performs face recognition on the user. After the face recognition is successful, the main control module 102 controls the projection module 103 to form a projection interface of the learning interface, which can supervise the student's learning in a timely manner and further improve the learning efficiency of the learning assistance system.

[0039] Figure 3 The module structure of the learning assistance system provided in the third embodiment of the present invention is shown. For ease of description, only the parts related to the embodiments of the present invention are shown, and are described in detail below:

[0040] In one embodiment of the present invention, in order to improve the convenience of controlling the learning assistance system, such as... Figure 2 As shown, the main control module 102 has a built-in voice recognition module 301;

[0041] The voice recognition module 301 recognizes the user's voice information, and the main control module 102 controls the projection module 103 to form the learning interface or feedback interface into a projection interface according to the preset projection command fed back by the voice recognition module 301.

[0042] The speech recognition module 301 can utilize iFlytek's speech recognition system. iFlytek's speech recognition system enables language recognition and comparison, as well as speech transcription. Long Form ASR (Audio-Speech Recognition) is based on a deep fully convolutional neural network, converting long audio segments (up to 5 hours) into text data, providing a foundation for information processing and data mining. iFlytek's open platform possesses advanced speech recognition technology, with core technologies reaching advanced levels and a speech recognition accuracy exceeding 98%. Based on user speech characteristics, personalized word language models are established, recognition parameters are adjusted, and recognition effects are continuously optimized to improve the accuracy of personalized word recognition. It supports recognition of seven languages: Chinese, English, Japanese, Korean, Russian, French, and Spanish, and also provides recognition of dialects such as Cantonese, Henan dialect, and Sichuan dialect. With the help of iFlytek's speech system, this learning aid system can accurately recognize speech, compare and score it, improving children's reading and oral expression abilities. The speech transcription function improves learning and work efficiency.

[0043] The voice recognition module 301 includes a microphone. When a user performs voice control, the microphone of the voice recognition system receives and recognizes the user's voice information. For example, the voice recognition module 301 can be used to control the learning assistance system to be turned on and off. For instance, when the keyword "Xiong Da" is recognized, the voice recognition module 301 in the learning assistance system is activated and voice recognition begins.

[0044] The preset projection instruction is a projection instruction pre-set according to actual conditions and specific needs. For example, the preset projection instruction may include "desktop projection." Those skilled in the art will understand that the preset projection instruction may also include other preset projection instructions besides "desktop projection." For example, the preset projection instruction may also include "wall projection" and "ceiling projection," etc., and this embodiment of the invention does not impose any particular limitations on this. We can refer to the projection modes corresponding to the preset projection instructions "desktop projection," "wall projection," and "ceiling projection" as different projection modes such as "desktop mode," "PPT mode," and "ceiling mode," respectively.

[0045] When the voice recognition system recognizes the preset projection command for "desktop projection", the main control module 102 controls the projection module 103 to project the learning interface or feedback interface onto a desktop; when the voice recognition system recognizes the preset projection command for "wall projection", the main control module 102 controls the projection module 103 to project the learning interface or feedback interface onto a wall; when the voice recognition system recognizes the preset projection command for "ceiling projection", the main control module 102 controls the projection module 103 to project the learning interface or feedback interface onto a ceiling.

[0046] In this embodiment of the invention, the voice recognition module 301 recognizes the user's voice information, and the main control module 102 controls the projection module 103 to form a projection interface from the learning interface or feedback interface according to the preset projection command fed back by the voice recognition module 301, which can improve the convenience of controlling the learning assistance system.

[0047] Figure 4 The diagram shows the structure of the projection module 103 in the learning assistance system provided in the fourth embodiment of the present invention. For ease of description, only the parts related to the embodiments of the present invention are shown, and are described in detail below:

[0048] In one embodiment of the present invention, in order to improve the projection effect, such as Figure 4 As shown, the projection module 103 includes a projection optical engine 402 of the optical engine lens 401 and a projection optical engine driver 403.

[0049] The main control module 102 controls the optical engine lens 401 of the projection optical engine 402 through the projection optical engine driver 403 to form the learning interface or feedback interface into a projection interface.

[0050] The projection module 103 is connected to the main control module 102 via an HDMI cable. The main control module 102 converts the learning interface or the feedback interface from the online teacher into RGB signals via the HDMI cable. The projection optical engine driver 403 controls the optical engine lens 401 of the projection optical engine 402 to convert the RGB signals into the projection interface. In addition, the projection module 103 may also include heat dissipation auxiliary equipment such as a heat sink and a fan to achieve heat dissipation function and reduce the temperature of the projection module 103 during operation.

[0051] In one embodiment of the present invention, the core component of the projection module 103, the projection optical engine 402, can be an OPD27 optical engine. Those skilled in the art will understand that the core component of the projection module 103, the projection optical engine 402, can also be other projection optical engines besides the aforementioned OPD27 optical engine; the embodiments of the present invention do not impose any particular limitation on this.

[0052] In this embodiment of the invention, the main control module 102 controls the optical engine lens 401 of the projection optical engine 402 through the projection optical engine driver 403 to form a projection interface of the learning interface or feedback interface, which can improve the projection effect.

[0053] Figure 5 The diagram illustrates the structure of the infrared touch module 104 in the learning assistance system provided in the fifth embodiment of the present invention. For ease of description, only the parts related to the embodiments of the present invention are shown, and are detailed below:

[0054] In one embodiment of the present invention, in order to improve the sensitivity and accuracy of infrared touch control, such as Figure 5 As shown, the infrared touch module 104 includes an infrared focusing camera 501 and an infrared laser emitter 502.

[0055] The infrared laser emitter 502 forms an infrared laser film on the projection interface. The user's touch operation on the projection interface is fed back to the main control module 102 through the infrared focusing camera 501. The main control module 102 responds to the user's touch operation.

[0056] During assisted learning, the infrared laser emitter 502 forms an infrared laser film slightly larger than the projection interface on a plane 1-2mm above the projection interface. When the user performs a touch operation on the projection interface, the user's touch operation is emitted to the infrared focusing camera 501 through the infrared laser film. The infrared focusing camera 501 feeds back the user's touch operation to the main control module 102, so that the main control module 102 responds to the user's touch operation, realizing flexible interaction with the learning assistance system, thereby improving the sensitivity and accuracy of infrared touch, and thus improving the interactivity of the learning assistance system.

[0057] In addition, the infrared touch module 104 may also include other components besides the aforementioned infrared focusing camera 501 and infrared laser emitter 502, such as a laser adjustment mechanism fixing plate (LT3-TJJGGDP), a laser adjustment mechanism fixing base (LT3-TJJGGDZ), and embedded projection virtual touch software components. Touch interaction can be achieved through hands, styluses, etc. Furthermore, the infrared touch module 104 also supports multi-touch functionality.

[0058] In this embodiment of the invention, the infrared laser emitter 502 forms an infrared laser film on the projection interface. The user's touch operation on the projection interface is fed back to the main control module 102 through the infrared focusing camera 501. The main control module 102 responds to the user's touch operation, which can improve the sensitivity and accuracy of infrared touch.

[0059] Figure 6 A schematic diagram of the learning assistance system provided in the sixth embodiment of the present invention is shown. For ease of description, only the parts related to the embodiments of the present invention are shown, and are described in detail below:

[0060] In one embodiment of the present invention, in order to improve the portability of the learning assistance system, such as Figure 6 As shown, the learning assistance system also includes a first housing 602 and a second housing 603 that are interconnected by a connector 601.

[0061] An infrared focusing camera 501, an optical engine lens 401, and a scanning module 101 are arranged inside a first housing 602. A transparent part 604 is fixed on the first housing 602 at a position corresponding to the infrared focusing camera 501, the optical engine lens 401, and the scanning module 101.

[0062] The main control module 102, the projection optical engine driver 403, and the infrared laser emitter 502 are arranged inside the second housing 603; an opening is fixed on the second housing 603 at the position corresponding to the infrared laser emitter 502, and the infrared laser emitter 502 forms an infrared laser light film on the projection interface through the opening at the corresponding position on the second housing 603.

[0063] In this embodiment of the invention, the learning assistance system includes a first housing 602 and a second housing 603, which are interconnected by a connector 601. The first housing 602 is a spherical housing. However, those skilled in the art will understand that the first housing 602 can also be a housing of other shapes besides a spherical housing, such as a cube or a polyhedron, and this embodiment of the invention does not impose any particular limitation on this. The second housing 603 may include an annular three-dimensional structure with a bottom plane. The learning assistance system is stably placed on a horizontal surface, such as a tabletop, via the bottom plane of the second housing 603. Again, those skilled in the art will understand that the second housing 603 may include other three-dimensional structures besides the annular three-dimensional structure, such as a cube or a polyhedron, and this embodiment of the invention does not impose any particular limitation on this.

[0064] In a preferred embodiment, the first housing 602 includes a protruding structure (not shown) near the connector 601, and the second housing 603 includes a recessed structure (not shown) near the connector 601. The protruding structure of the first housing 602 and the recessed structure of the second housing 603 are adapted to engage. When the learning assistance system is not used, the protruding structure of the first housing 602 can be adapted to engage within the recessed structure of the second housing 603.

[0065] To improve the portability of the learning assistance system, an infrared focusing camera 501, an optical engine lens 401, and a scanning module 101 are arranged inside a first housing 602. A transparent element 604 is fixed on the first housing 602 at positions corresponding to the infrared focusing camera 501, the optical engine lens 401, and the scanning module 101, allowing these components to perform their respective functions through the transparent element 604. This transparent element 604 can be similar to the transparent element 604 used in smart terminal cameras or camera lenses; it is a commonly used transparent component on lenses, and will not be described in detail in this embodiment.

[0066] To reduce the size of the learning assistance system and improve its portability, the main control module 102, the projection optical engine driver 403, and the infrared laser emitter 502 are arranged inside the second housing 603. At the same time, an opening (not shown in the figure) is fixed on the second housing 603 at the corresponding position of the infrared laser emitter 502. The infrared laser emitter 502 forms an infrared laser light film on the projection interface through the opening at the corresponding position on the second housing 603.

[0067] In this embodiment of the invention, the infrared focusing camera 501, the optical engine lens 401 and the scanning module 101 are respectively arranged in the first housing 602, and the main control module 102, the projection optical engine driver 403 and the infrared laser emitter 502 are arranged in the second housing 603, which can reduce the size of the learning assistance system and improve the portability of the learning assistance system.

[0068] Figure 7 A schematic diagram of the learning assistance system provided in the seventh embodiment of the present invention is shown. For ease of description, only the parts related to the embodiments of the present invention are shown, and are described in detail below:

[0069] In one embodiment of the present invention, in order to improve the flexibility of adjusting the learning assistance system, such as Figure 7 As shown, the connector 601 between the first housing 602 and the second housing 603 includes a manually adjustable telescopic structure 701.

[0070] The connector 601 connecting the first housing 602 and the second housing 603 may include a manually adjustable telescopic structure 701. In actual use, the user can manually adjust the length of the connector 601 to adjust the height of the first housing 602, and change the size of the projection interface in combination with the distance between the learning assistance system and the projection interface, so as to adapt to different users and projection habits and improve the flexibility of adjusting the learning assistance system.

[0071] Additionally, the learning assistance system may also include a telescopic drive module, such as a motor, connected to the main control module 102. Adjustment control commands can be input via voice or buttons, and feedback is sent to the main control module 102. The main control module 102, based on the received adjustment control commands, drives the connector 601 to extend or retract via the telescopic drive module to adjust the height of the first housing 602. When the adjustment control command is input via voice, the connector 601 can extend or retract according to a predetermined adjustment length via the telescopic drive module. When the adjustment control command is input via a button, the connector 601 can be continuously extended or retracted via the telescopic drive module while the button is pressed. Those skilled in the art can configure this according to actual needs and specific circumstances; this embodiment of the invention does not impose any particular limitations.

[0072] In this embodiment of the invention, by adjusting the manually adjustable telescopic structure 701, the height of the first housing 602 or the distance between the first housing 602 and the second housing 603 can be adjusted, thereby improving the flexibility of adjusting the learning assistance system.

[0073] Figure 8 The diagram shows a six-sided structure of the learning assistance system provided in the eighth embodiment of the present invention. For ease of description, only the parts related to the embodiment of the present invention are shown, and are described in detail below:

[0074] In one embodiment of the present invention, in order to improve the portability of the learning assistance system, such as Figure 8 The diagram shows a six-sided structure of a learning assistance system, where:

[0076] As shown in (a) to (f), the first housing 602 and the second housing 603 are interconnected by a manually adjustable telescopic structure 701, and the face recognition module 201 is located at the junction of the telescopic structure 701 and the second housing 603. The scanning module 101, the infrared focusing camera 501, and the optical engine lens 401 are arranged inside the first housing 602, while the main control module 102, the projection optical engine driver 403, and the infrared laser emitter 502 are arranged inside the second housing 603 (not shown in the figure).

[0077] In addition, in one embodiment of the present invention, a plurality of heat dissipation holes 702 are provided on both sides of the transparent part 604 on the first housing 602 to facilitate heat dissipation of the learning assistance system, reduce the operating temperature of the learning assistance system, and improve the heat dissipation performance of the learning assistance system.

[0078] Figure 9 The diagram illustrates the state of the learning assistance system provided in the ninth embodiment of the present invention under different projection modes. For ease of description, only the parts related to the embodiments of the present invention are shown, and are detailed below:

[0079] In one embodiment of the present invention, in order to improve the diversity of the projection function of the learning assistance system, based on the above-described module structure, the learning assistance system further includes an angle adjustment module (not shown in the figure) that is connected to the projection module 103 and the main control module 102 respectively.

[0080] The main control module 102 is also used to control the angle adjustment module to drive the projection module 103 to adjust the projection angle according to the preset projection command fed back by the voice recognition module 301. The main control module 102 controls the projection module 103 to form the learning interface or feedback interface into a projection interface under the projection angle.

[0081] The angle adjustment module is connected to both the projection module 103 and the main control module 102. Specifically, the angle adjustment module may include a drive motor. Those skilled in the art will understand that the angle adjustment module may also include other devices or components with the same projection angle adjustment function besides the aforementioned drive motor; this embodiment of the invention does not impose any particular limitations in this regard.

[0082] Specifically, the housing, including the infrared focusing camera 501, the optical engine lens 401, the scanning module 101, and the transparent component 604 on the first housing 602, can rotate freely within a 180° vertical plane. During assisted learning projection, the voice recognition module 301 recognizes the user's preset projection commands and feeds the recognition results back to the main control module 102. Based on the feedback of the preset projection commands, the main control module 102 controls the angle adjustment module to drive the projection module 103 to adjust the projection angle, thereby enabling the learning interface or feedback interface to be projected into a projected interface under different projection modes.

[0083] For example, the preset projection instructions include "desktop projection", "wall projection" and "ceiling projection", with corresponding projection modes of "desktop mode", "PPT mode" and "ceiling mode" respectively.

[0084] As shown in (a), (a) is a state diagram in desktop projection mode. When the preset projection command is "desktop projection", the main control module 102 controls the angle adjustment module to drive the optical engine lens 401 of the projection module 103 to face downward according to the feedback "desktop projection" command, so as to achieve a state that is almost perpendicular to the desktop, so as to form a desktop projection interface for the learning interface or feedback interface.

[0085] As shown in (b), (b) is a state diagram of the ceiling projection mode. When the preset projection command is "wall projection", the main control module 102 controls the angle adjustment module to drive the optical engine lens 401 of the projection module 103 to reach a state that is basically perpendicular to the ceiling according to the feedback "desktop projection" command, so as to form the learning interface or feedback interface into a desktop projection interface.

[0086] As shown in (c), (c) is a state diagram of the wall projection mode. When the preset projection command is "wall projection", the main control module 102 controls the angle adjustment module to drive the optical engine lens 401 of the projection module 103 to be basically perpendicular to the wall according to the feedback "desktop projection" command, so as to form the learning interface or feedback interface into a desktop projection interface.

[0087] In this embodiment of the invention, the learning assistance system further includes an angle adjustment module. The main control module 102 controls the angle adjustment module to drive the projection module 103 to adjust the projection angle according to the preset projection command fed back by the voice recognition module 301. The main control module 102 controls the projection module 103 to form the learning interface or feedback interface into a projection interface under the projection angle, thereby realizing the projection function under different projection modes and improving the diversity of the projection function of the learning assistance system.

[0088] In one embodiment of the present invention, in order to further improve the projection effect of assisted learning and thus improve the efficiency of assisted learning, the learning assistance system further includes, based on the above-described module structure:

[0089] An auxiliary lighting module (not shown in the figure) is fixed inside the second housing 603 and connected to the main control module 102. A light-transmitting hole 605 is provided on the second housing 603 at a position corresponding to the auxiliary lighting module.

This auxiliary lighting module includes an LED light source and an LED driver power supply connected to the main control module 102. The main control module 102 drives the LED light source to emit light via the LED driver power supply.

[0092] In one embodiment of the present invention, the auxiliary lighting module can be controlled and adjusted via a voice recognition system. Specifically, the main control module 102 controls and adjusts the auxiliary lighting module to emit light through the light-transmitting hole 605 based on the lighting control commands recognized by the voice recognition module 301. For example, the lighting control commands include "brighten up," "dim down," "turn off auxiliary lighting," and "turn on auxiliary lighting," etc. When the main control module 102 receives these lighting control commands from the voice recognition module 301, it drives the LED light source to emit light via the LED driver power supply, or turns the LED light source on and off, etc.

[0093] Additionally, it's understandable that this auxiliary light module can also serve as supplementary light during scanning, making the resulting learning interface clearer. For example, the auxiliary light module can be turned on simultaneously with the scanning module.

[0094] In this embodiment of the invention, the learning assistance system also includes an auxiliary lighting module. The main control module 102 controls and adjusts the auxiliary lighting module to emit light through the light-transmitting hole 605 according to the lighting control command recognized by the voice recognition module 301, which can further improve the projection effect of assisted learning and thus improve the efficiency of assisted learning.

Specifically, the user performs touch button operations via the touch button module. After receiving the user's touch button operation, the touch button module feeds back to the main control module 102. The main control module 102 controls and adjusts the intensity and on / off state of the auxiliary lighting module according to the touch button operation. Additionally, the learning assistance system can also be turned on and off via the touch button module. That is, the user performs touch button operations on the touch button module, and after receiving the user's touch button operation, the touch button module feeds back to the main control module 102. The main control module 102 controls the on / off state of the learning assistance system according to the touch button operation.

[0098] In this embodiment of the invention, the touch button module receives the user's touch button operation, and the main control module 102 controls the opening and closing of the learning assistance system and controls and adjusts the illumination of the auxiliary light module according to the touch button operation fed back by the touch button module, which can improve the flexibility and versatility of controlling the learning assistance system.

[0099] In one embodiment of the present invention, in order to improve the functional versatility of the learning assistance system and thus improve the efficiency of assisted learning, the learning assistance system further includes an audio system (not shown in the figure) connected to the main control module 102, based on the above-described modular structure. The main control module 102 controls the audio system to play audio and video information in the assisted learning module. Additionally, the volume of the audio system can be controlled and adjusted via a voice recognition system or a touch button module.

[0100] In this embodiment of the invention, the learning assistance system also includes an audio system. The main control module 102 controls the audio system to play audio and video information in the learning assistance module, which can improve the functional diversity of the learning assistance system. The volume of the audio system can be controlled and adjusted by the voice recognition system or the touch button module, which can improve the flexibility of controlling the learning assistance system.

This embodiment of the invention will not elaborate on these aspects further.
