Description

Technical Field

[0001] This invention relates to the field of educational technology, specifically a multi-sensory interactive educational digital oil painting system. Background Technology

[0002] The multi-sensory interactive educational digital oil painting system is a new teaching tool that integrates digital technology and art education. At its core, it lowers the threshold for oil painting creation by linking multiple senses such as sight, hearing, and touch, while conveying art knowledge and meeting the enlightenment and learning needs of children, art beginners and other groups.

[0003] Currently, most digital oil painting systems focus solely on visual coloring operations, lacking a multi-sensory collaborative mechanism. They transmit knowledge through a single visual input, making it difficult to activate multi-sensory memory channels. This results in abstract color theories, brushstroke techniques, and other knowledge being difficult to visualize and understand, making the learning process tedious and inefficient in knowledge absorption. To address this, we propose a multi-sensory interactive educational digital oil painting system. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-sensory interactive educational digital oil painting system. This system solves the problem that most existing digital oil painting systems only focus on visual coloring operations, lack a multi-sensory collaborative mechanism, and transmit knowledge only through a single visual input. This makes it difficult to activate multi-sensory memory channels, resulting in abstract color theories, brushstroke techniques, and other knowledge being difficult to visualize and understand, making the learning process tedious and inefficient in terms of knowledge absorption.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a multi-sensory interactive educational digital oil painting system, comprising a knowledge visualization draft layer, an intelligent auxiliary terminal layer, and a multi-sensory interactive component layer;

[0006] The knowledge visualization drawing layer is used to present digital oil painting drawings that integrate educational information. Color theory annotations, brushstroke technique tips, and pop-up windows containing background knowledge of famous paintings are embedded in the drawings.

[0007] The intelligent auxiliary terminal layer includes a touch operation module, a data processing module, and an educational resource library. The touch operation module is used to receive user painting operation instructions. The data processing module is used to parse operation data and link the components of each layer. The educational resource library stores graded oil painting teaching content.

[0008] The multi-sensory linkage component layer includes an audio interaction unit, a tactile feedback unit, and an olfactory simulation unit, which are respectively used to output audio associated with the painting, provide tactile feedback of brushstrokes, and release scents adapted to the painting scene, realizing a multi-sensory collaborative oil painting education experience involving sight, hearing, touch, and smell. This system uses digital oil painting as a carrier and integrates a five-sense collaborative mechanism of sight, hearing, touch, taste, and smell to concretize subject knowledge and cultural content. Through fun coloring operations, it achieves immersive learning, improving the efficiency of knowledge absorption and the depth of cultural cognition.

[0009] Furthermore, the knowledge visualization drawing layer includes basic drawing units and dynamic knowledge embedding units;

[0010] The basic drawing unit provides a blank canvas and line drawing templates in different styles, allowing users to freely choose their creative themes.

[0011] The dynamic knowledge embedding unit can pop up dynamic annotations in the corresponding area of ​​the drawing according to the user's drawing progress. The annotations can be expanded or collapsed by touch operation to avoid interfering with the drawing vision. The knowledge visualization drawing layer embeds educational information such as color theory and brushstroke techniques through dynamic annotations. Combined with the audio explanation, tactile feedback and scene smell of the multi-sensory linkage component layer, relying on the right brain image memory advantage and alpha wave modulation technology, it activates the hippocampal memory area. Combined with multi-sensory synchronous input, it constructs a knowledge transformation path that conforms to the Ebbinghaus multi-channel memory model, which significantly improves the memory retention rate.

[0012] Furthermore, the touch operation module of the intelligent auxiliary terminal layer adopts an 8192-level pressure-sensitive touch screen, which supports the recognition of the pen tip pressure, movement speed, and tilt angle when the user is drawing. It can simulate the brushstroke effects of more than 12 kinds of painting tools such as oil paintbrushes, palette knives, and fan brushes. The touch screen surface is covered with a canvas-like texture film, which restores the friction texture of traditional oil canvas and enhances the realism of the drawing operation. The 8192-level pressure sensitivity of the touch operation module and the canvas-like texture film, combined with the differentiated vibration of the haptic feedback unit, accurately restore the texture of traditional oil painting brushstrokes. The basic drawing unit provides a variety of line drawing templates, which can help beginners get started quickly. The coloring operation is used as a fun entry point, and the subject knowledge is simultaneously injected with voice explanations and multi-sensory stimulation, so that the learning process has both a gamified experience and the effect of knowledge internalization, truly achieving the functional unity of "edutainment".

[0013] Furthermore, the data processing module of the intelligent auxiliary terminal layer includes a real-time parsing unit and a learning analysis unit. The real-time parsing unit can respond to user operations within 100ms and synchronously trigger the feedback output of the multi-sensory linkage component layer. The learning analysis unit generates a personalized learning profile by recording the user's color matching choices, pen stroke frequency, and knowledge annotation viewing frequency. When it detects that the user has a weakness in a certain knowledge point, it automatically pushes targeted teaching videos. The data processing module generates a personalized learning profile and pushes teaching videos for weak knowledge points. The three-level curriculum system of the educational resource library covers the entire stage from basic to creation, and the accompanying test question bank consolidates the learning effect, meeting the learning needs of different users such as beginners, advanced users, and creative practitioners.

[0014] Furthermore, the educational resource library of the intelligent auxiliary terminal layer is divided into basic courses, advanced courses, and creative courses. The basic courses include the mixing of the three primary colors and basic brushstroke exercises, while the advanced courses cover knowledge such as techniques for copying famous paintings and principles of composition. The creative courses provide guidance for themed creation. Each level of course is accompanied by a corresponding knowledge test question bank. After completing the course, users can consolidate what they have learned by answering questions. This solution effectively establishes a fixed mapping relationship between knowledge points and numerical codes and color symbols, such as mathematical formulas corresponding to the blue family and English words corresponding to the red family, forming a three-in-one coding structure of "knowledge point-number-color", which strengthens the brain's concrete memory path for abstract knowledge.

[0015] Furthermore, the audio interaction unit of the multi-sensory linkage component layer includes an embedded surround sound speaker integrated into the frame of the intelligent auxiliary terminal layer; it can output dual audio information based on the content of the knowledge visualization drawing layer, and the intelligent terminal simultaneously plays the voice explanation corresponding to the drawing content, covering knowledge point analysis, application scenarios and memory prompts, constructing an auditory input channel, and coordinating with visual and operational behaviors to form a multi-channel knowledge input closed loop, significantly improving the information retention rate, transforming traditional patterns and cultural relic designs into coded drawings, and combining voice explanations and smell simulation to create an immersive cultural experience, enhancing the public's understanding and emotional connection with intangible cultural heritage and historical heritage.

[0016] Furthermore, the tactile feedback unit of the multi-sensory linkage component layer adopts a distributed piezoelectric vibration module, which is evenly distributed below the touch operation module. When the user simulates different painting actions, it outputs differentiated vibration feedback. Flat painting operation corresponds to low-frequency uniform vibration, dot painting operation corresponds to high-frequency intermittent vibration, and scraping operation corresponds to strong amplitude pulse vibration. This allows the user to intuitively perceive the differences in operation of different brushstrokes through touch. The system supports the structured implantation of various knowledge types such as subject formulas, foreign language vocabulary, and traditional cultural symbols. Through classification coding and color differentiation, it realizes cross-disciplinary and cross-scenario knowledge visualization and personalized teaching adaptation.

[0017] Furthermore, the olfactory simulation unit of the multi-sensory linkage component layer includes a replaceable scent box and a precise volume control valve; the scent box is pre-stored with more than 15 scene-specific scent agents; the data processing module can automatically match the scent according to the core elements in the painting, adjust the scent release concentration through the volume control valve, and supports users to manually select the scent type. The design includes a replaceable scent box, multiple style line drawing templates, etc., to adapt to different themes of oil painting creation; the device supports different usage postures such as sitting and standing, and can be used for personal learning at home or as a teaching tool for training institutions. The applicable scenarios cover multiple fields such as personal interests and professional teaching. It is equipped with edible taste carriers that correspond one-to-one with the colors of the painting, such as yellow bananas corresponding to the yellow area. Made from natural plant extracts, it is safe and edible. Students taste the same color food at the same time during the coloring process, triggering taste and visual synesthetic response, enhancing the strength of neural synaptic connections, and improving memory consolidation.

[0018] Furthermore, it also includes a cloud collaboration layer, which communicates with the intelligent auxiliary terminal layer to support cloud backup and multi-device synchronization of user artwork and learning data. It also provides online teacher-student interaction functions, allowing users to upload their artwork to the cloud, receive teacher annotations and guidance, participate in online oil painting creation and exchange activities, share multi-sensory painting experiences, and access modular knowledge drafts and supporting terminals. It supports customized theme courses for institutions, such as scientific experiments and ancient poetry appreciation, enriching teaching methods, enhancing the differentiated competitiveness of courses, and utilizing alpha waves to regulate focus, combined with tactile brushstrokes and color guidance, to help students with attention deficit disorder stabilize their emotions, focus on tasks, and improve learning participation and operational persistence.

[0019] Furthermore, the cloud-based collaborative layer includes a data management module and an interactive teaching module. The data management module is used to classify and store works, learning data, and multi-sensory records. The interactive teaching module includes teacher-student interaction and user community sub-modules to facilitate learning and communication. The cloud-based collaborative layer supports work backup and multi-device synchronization. The teacher-student interaction sub-module provides precise annotation guidance, and the user community sub-module allows users to share works with multi-sensory information. Combined with creative challenges, it enhances communication and creative enthusiasm among users, creating an immersive learning community atmosphere. Parents and children can complete knowledge-based artwork together, combining taste snacks and voice interaction to achieve collaborative learning in a relaxed atmosphere, enhancing parent-child communication and knowledge internalization.

[0020] In summary, the technical effects and advantages of this invention are as follows:

[0021] 1. In this invention, the knowledge visualization drawing layer embeds educational information such as color theory and brushstroke techniques through dynamic annotation. Combined with the audio explanation, tactile feedback and scene smell of the multi-sensory linkage component layer, relying on the right brain image memory advantage and alpha wave modulation technology, the hippocampal memory area is activated. Combined with multi-sensory synchronous input, a knowledge transformation path that conforms to the Ebbinghaus multi-channel memory model is constructed, which significantly improves the memory retention rate.

[0042] I. Implementation Scenarios and Prerequisites

[0043] 1.1 Implementation Scenario Selection

[0044] Children's art training institutions and home learning scenarios were selected as the core implementation scenarios:

[0045] Institutional Scenario: Configure 10 system devices for small class teaching of up to 20 people, which need to meet the requirements of "collective demonstration + personalized guidance" and be compatible with the standard drawing size of 60cm×80cm;

[0046] Home use: Each device is designed for 1-2 people and supports two usage modes: desktop placement in the living room and floor stand in the bedroom. It is compatible with portable artwork sizes of 30cm x 40cm.

[0047] II. Specific Implementation Steps

[0048] 2.1 System Startup and Artwork Selection

[0049] When the device is powered on, the system will automatically start and complete a hardware self-test. After the self-test passes, the main interface will be displayed.

[0050] Users select the usage scenario through touch operation, and the system recommends the drawing size according to the scenario: the default line drawing size for institutional scenarios is 60cm×80cm, and the default line drawing size for home scenarios is 30cm×40cm.

[0051] Taking "Family Learning - Impressionist Sunflower Line Drawing" as an example, after the user selects the line drawing, the basic drawing unit of the knowledge visualization drawing layer will display the line drawing on the touch screen, and the dynamic knowledge embedding unit will automatically hide the annotations, waiting for the user to start drawing.

[0052] 2.2 Drawing Operation and Multi-sensory Interaction Feedback

[0053] Touch operation and visual feedback: Users can draw sunflower petals on the touch screen using the accompanying digital pen. The 8192-level pressure-sensitive touch screen recognizes the pen tip pressure in real time and presents the corresponding brush stroke effect on the drawing. The canvas-like texture film restores the friction resistance of traditional painting.

[0054] Audio interaction feedback: When the user draws the edge of the petal, the real-time parsing unit of the data processing module identifies the operation area and triggers the audio interaction unit to output dual audio, scene ambient sound and synchronous narration sound;

[0055] Haptic feedback: When the user switches to the "pointillism" brush to draw the sunflower head, the distributed piezoelectric vibration module outputs 300Hz high-frequency intermittent vibration; when the user switches to the "flat wash" brush to fill the background color of the flower head, the vibration module switches to 100Hz low-frequency uniform vibration, allowing the user to perceive the difference in brush strokes through touch.

[0056] Olfactory simulation feedback: The data processing module identifies the core element of the artwork, "sunflower," and controls the precise volume control valve of the olfactory simulation unit to open, releasing a matching mixture of sunflower fragrance and grassy scent.

[0057] 2.3 Dynamic Knowledge Embedding and Personalized Guidance

[0058] When the user finishes drawing the sunflower head and enters the flower stem drawing stage, the dynamic knowledge embedding unit pops up dynamic annotations in the flower stem area. The user can click on the annotation to expand the 3D animation demonstration, and click again to collapse the annotation.

[0059] If the user repeatedly draws the flower stem but still experiences perspective deviation, the learning and analysis unit of the data processing module records the operation, generates a personalized learning profile, and automatically pushes instructional videos.

[0060] After a user completes a single step of the drawing, the system will pop up a knowledge test. If the user answers correctly, the next level of the drawing will be unlocked; if the user answers incorrectly, supplementary courseware on color theory will be pushed to them.

[0061] 2.4 Artwork Storage and Cloud Interaction

[0062] After the drawing is completed, the user clicks to save the artwork. The intelligent auxiliary terminal layer automatically records the creation process and uploads the artwork and learning data to the cloud collaboration layer via WiFi 6.

[0063] The data management module categorizes and stores data according to "User ID (e.g., Family User ID: F202405) - Learning Stage (Basic) - Project Type (Sunflower)", and uses AES-256 encryption algorithm to ensure privacy and security.

[0064] If a user selects "Teacher-Student Interaction", they can share their work with the linked teacher account. The teacher can view the work through the teacher-student interaction sub-module of the cloud interactive teaching module, add visual annotations using the annotation tool, and the annotations will be pushed to the user's device simultaneously.

[0065] Users can also join the "Children's Oil Painting Exchange Group" through the user community sub-module. When sharing their works, the system automatically includes audio and smell configuration information of the creation process. Other users can trigger corresponding multi-sensory feedback when viewing the works, achieving "immersive sharing".

[0066] 2.5 System Iteration and Maintenance

[0067] The cloud-based data analysis platform compiles user learning data daily. When the mastery rate of a certain knowledge point is below 80%, it automatically updates the educational resource library and supplements the interactive practice courseware for that knowledge point.

[0068] After the odorant in the odor box is used up, users can purchase a replacement pack. The old odor box can be removed by using the buckle structure on the side of the device. After replacing the box with a new one, the system will automatically identify the odor type and update the odor-artwork matching library.

[0069] We update the system monthly via OTA to optimize artwork rendering effects, multi-sensory synchronization algorithms, and cloud interaction stability.

[0070] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
