[0021] Figure 1 This is a flowchart of the present invention. Detailed Implementation

[0022] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1 like Figure 1As shown, an AI-based presentation tool integrates multiple functional modules to achieve one-click PPT generation, collaborative editing, and intelligent management. The system adopts a modular design, including a user management module, a permission management module, an AI-driven PPT generation module, a sharing and collaboration module, a canvas customization module, a browsing mode module, a saving and synchronization module, and a template library management module. These modules work together to provide an efficient, secure, and user-friendly PPT creation experience. The system can be deployed on cloud servers, personal computers, or mobile terminals, and its functions are implemented through computer programs.

[0024] Detailed implementation of the module 1. User Management Module The user management module handles user registration, login, and account information maintenance. In this embodiment, the module integrates a secure authentication mechanism based on the OAuth 2.0 protocol, supporting third-party logins (such as Google and WeChat). Simultaneously, the module supports multi-factor authentication (MFA), enhancing security through methods such as SMS verification codes or biometrics (such as fingerprints). User information is stored in an encrypted database to ensure data privacy.

[0025] During registration, users provide basic information (such as email address and password), and the system sends a verification email to activate the account. During login, the OAuth 2.0 protocol handles token issuance and verification, and multi-factor authentication is triggered during sensitive operations (such as changing passwords). Account information maintenance includes updating personal profiles, changing passwords, and binding security devices.

[0026] 2. Access Control Module The access control module implements role-based access control (RBAC), supporting three levels of roles: administrator, editor, and viewer. Administrators can configure system parameters (such as template library settings) and user permissions; editors can create and modify PPT content; and viewers can only browse and comment.

[0027] Dynamic permission allocation function: For fine-grained control, the module calculates the user's overall permission score for PPT objects using the following function: ; In the above formula, This represents the overall permission score of user u for PPT object o; The weighting factor for the i-th permission dimension (e.g., edit, share, delete); This represents the permission status value (0 or 1) of user u in dimension i. This indicates the weight of the user role: 3 for administrator, 2 for editor, and 1 for viewer. This represents the role adjustment coefficient, with a default value of 0.5. And, when (threshold) Access is authorized when the score is set to 2.5; otherwise, it is denied. For example, if an editor attempts to modify a PowerPoint presentation, the operation is allowed if the calculated score is 2.8. Permission data is stored in a relational database. Each access request is processed in real-time, and the score is compared to the threshold. Role weights and weighting factors can be adjusted through the administrator interface.

[0028] 3. AI-driven PPT generation module This module integrates pre-trained Transformer architecture models (such as BERT or GPT variants) and automatically generates PPT outlines, content text, chart recommendations, style layouts, and text styles (including font gradient effects and font formatting) based on user-input topics, keywords, or voice commands. Real-time preview is supported, allowing users to adjust the generated results instantly.

[0029] Content generation steps: Step 1: Use a Natural Language Processing (NLP) model to extract keywords and semantic features from the user input. For example, if the user inputs "Intelligent Vehicle Market Report", the model identifies the keywords "intelligent vehicle" and "market" and generates structured data, including titles (such as "Intelligent Vehicle Development Trends"), sections (such as "Market Overview" and "Technical Analysis"), a list of keywords, and layout types (such as title page and chart page).

[0030] Step 2: Calculate the matching degree between the user input and templates in the template library based on the attention matching mechanism. Specifically, the user input is encoded as a query vector Q, and the template features are encoded as a key vector K and a value vector V. The matching degree is obtained by similarity calculation (such as cosine similarity) and weighted summation.

[0031] Step 3: Fill the corresponding text boxes in the template with the generated content, and dynamically adjust the font size and page layout according to the content length. For example, if the text is too long, the system automatically reduces the font size or increases the text box size. The model is deployed on a GPU server and accessed via an API interface. Real-time preview is implemented through front-end JavaScript, and the content is rendered as a PPT sketch immediately after generation.

[0032] 4. Text Style Processing Module This module provides automatic or user-defined settings for font gradient effects and various font formats for PPT text content.

[0033] Font gradient effects: Supports at least one of the following: color gradient (e.g., from blue to green), size gradient (e.g., font size gradually increases), and transparency gradient (e.g., from transparent to opaque). Gradient parameters can be implemented using CSS3 gradient syntax or SVG filters and rendered in real-time in the Canvas.

[0034] Font formatting settings include font type (such as Source Han Sans, Arial), font size, bold, italic, underline, and color. Users can adjust these settings directly in the editing interface, or the AI ​​can automatically recommend fonts based on the semantics of the content (e.g., SimSun is recommended for formal reports, while Artistic Fonts are recommended for creative presentations).

[0035] Style inheritance and matching: The system supports style templates, allowing users to save a set of styles as templates and apply them to multiple text boxes or pages. AI will also automatically match the best style template when generating content.

[0036] 5. Sharing and Collaboration Module This module generates time-sensitive and access-controlled sharing links (e.g., valid for 7 days), allowing external users to annotate, comment on, and suggest modifications to specific areas of the PPT via an annotation interface. All annotation data is mapped to PPT elements using unique identifiers (e.g., UUIDs).

[0037] Annotation positioning is achieved by determining the position of the annotated area based on the base coordinates of the original elements in the canvas, the offset generated by user interaction, the original size of the elements, and the scaling factor of the canvas's adaptive adjustment. The specific calculation function is as follows: ; In the above formula, Represents the base coordinates of the original elements in the canvas; This represents the offset, which is dynamically determined by user interaction. This represents the element's original width and height; 's' represents the scaling factor, which adapts to the canvas; and all annotation data is stored in a lightweight JSON format, supporting version tracking and collaborative editing; sharing links are generated via encrypted tokens, and access control is integrated with the access management module. Annotation data is synchronized in real time via WebSocket to ensure data consistency during multi-user collaboration.

[0038] 6. Canvas Customization Module This module allows users to dynamically adjust the canvas width, height, and resolution to adapt to the display needs of different devices (such as PCs, tablets, or mobile phones).

[0039] Canvas parameters are implemented using HTML5 Canvas and CSS media queries. Users can adjust the canvas size by dragging handles, and the system calculates the scaling factor s in real time (used for annotation positioning and rendering). Resolution adjustment is based on the device pixel ratio (DPR) to ensure high-definition display.

[0040] 7. Browsing Mode Module This module offers a webpage stitching browsing mode, seamlessly stitching multiple slides into a single, continuous webpage, supporting smooth scrolling and full-screen preview.

[0041] The layout optimization function enables seamless display. The module calculates the total rendering height through the following function: ; In the above formula, represents the rendering height of the i-th page of the slide; represents the page spacing constant, with a default value of 20 pixels; represents the indicator function, which is 1 when i < N and 0 otherwise; C represents the correction factor used to compensate for browser rendering differences; the output T is used to generate the CSS layout of a single web page to achieve a smooth scrolling experience.

[0042] 8. Save and Synchronization Module This module adopts a page-independent saving mechanism. Each page of the slide is stored as an independent data block, and the network transmission efficiency is optimized through incremental synchronization technology.

[0043] Performance Optimization Model: To improve efficiency, the module calculates the total saving time through the following model: ; In the above formula, represents the total saving time; represents the basic saving overhead per page (in milliseconds); represents the data size of the i-th page (in KB); B represents the network bandwidth (in KB / ms); represents the compression coefficient, with a default value of 0.8. This model ensures <the global saving time and reduces redundant data transmission through differential synchronization. Each page of data is stored as a JSON object, and incremental synchronization is managed through version numbers (such as Git-style hashes). The saving operation is performed asynchronously in the background without the user's awareness.

[0044] 9. Template Library Management Module This module stores multiple types of preset PPT templates (such as business, education, and creative types), and supports users to upload custom templates and AI intelligent recommendations.

[0045] The template data is stored in a cloud storage service (such as AWS S3). The AI recommendation is based on the user's historical usage patterns and content matching degree (see the attention matching mechanism of the AI generation module). When the user uploads a template, the system automatically extracts features (such as colors and layouts) and indexes them.

[0046] 10. Real-time Collaboration Engine This tool integrates a real-time collaboration engine, supports multiple users to edit the same PPT simultaneously, and resolves editing conflicts through the operation transformation (OT) algorithm. The editing lock management mechanism determines the release time of the lock based on the combined effect of the time decay of the lock held by the user and the user priority coefficient.

[0047] In the lock management function, the lock strength is calculated as follows: ; In the above formula, t represents the time the user holds the lock; Indicates the attenuation factor; This indicates the user priority coefficient; 'e' represents a specific element in the PPT (such as a text box, a shape, an image, etc.). The lock is automatically released to avoid editing blockage. The OT algorithm coordinates editing operations through a central server, and the lock status is broadcast via WebSocket. The user interface displays the lock status (e.g., element border color changes).

[0048] Example 2 This invention also relates to a computer-readable storage medium (such as an SSD or cloud storage) storing a computer program that, when executed by a processor, performs all the aforementioned functions. The electronic device includes a memory, a processor, and the stored program; the device can be a cloud server, a personal computer, or a mobile terminal (such as an iPad). In implementation, the program code is written in Python (backend) and JavaScript (frontend), the database uses PostgreSQL, and the AI ​​model is based on the TensorFlow framework.

[0049] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
