Detailed Implementation

[0012] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0013] Filing cabinets are cabinets used to store documents and materials, and are generally used in offices, archives, document rooms, storage rooms, or personal studies.

[0014] However, existing file previews in filing cabinets typically rely on the cabinet's small display screen or user terminal device. Users need to search for the file list on the screen and then view the file content individually, which is cumbersome. Furthermore, the location of the file in the filing cabinet cannot be directly seen, and the amount of preview information is limited. It is difficult for users to locate the specific storage location based solely on the display screen, and they can only rely on additional queries or scattered navigation information. In addition, the file operation interaction methods in filing cabinets are mostly based on buttons, touch screens, or QR codes, which are lengthy and error-prone, especially for scenarios that require quick viewing, resulting in a poor user experience.

[0015] Based on this, embodiments of this application provide a filing cabinet. The following detailed description of the embodiments of this application is provided in conjunction with the accompanying drawings.

[0016] See Figure 1 The diagram illustrates the structure of a filing cabinet, which specifically includes a cabinet body, a holographic projection device, and a file management server. The cabinet body has multiple storage compartments. The file management server is used to retrieve file information of files stored in the cabinet based on received file search keywords, generate file preview content based on the file information, and send it to the holographic projection device. The file preview content includes at least file attribute information, file preview cover information, operation information, and storage compartment information for storing files. The operation information indicates the supported operations to be performed on the file. The holographic projection device is used to project the file preview content in the form of a holographic projection.

[0017] The filing cabinet in this embodiment, through the collaborative work of the cabinet body, holographic projection device, and file management server, can quickly retrieve and obtain relevant file information from the cabinet after receiving search keywords. Based on this information, it generates file preview content and projects it through the holographic projection device, significantly improving the efficiency of retrieval, location, and judgment. The projected file preview content includes at least file attribute information, file preview cover information, operation information, and storage compartment information for storing files. Users can intuitively complete identification and decision-making without removing the physical files, improving user experience and work efficiency. The operation information clearly indicates the operations that can be performed on the files and guides the retrieval and placement process in combination with the storage compartment information, reducing the risk of accidental retrieval, misplacement, and file damage, while improving traceability and security, and facilitating access control and auditing. The integrated design of the system helps reduce labor costs, training costs, and maintenance costs, improves space utilization and management consistency and reliability, and has good scalability, which can adapt to different quantities and types of files and the needs of future functional upgrades.

[0018] Based on the above embodiments, in some modified embodiments, the holographic projection device may include a projector and an optical reflective element; the projector is used to generate a light wavefront carrying the preview content of the document; the optical reflective element is used to generate and output a projection image based on the light wavefront, the projection image including at least the document preview cover information, projection operation buttons and storage compartment information for storing the document, the projection operation buttons including at least one of a copy button, a delete button, a modify button, an open button and a retrieve button.

[0019] By employing a holographic projection device composed of a projector and optical reflective elements, the light wavefront carrying the document preview content is converted into a projected image by the optical reflective elements and presented directly to the user in the form of a holographic projection inside the cabinet. This enhances the intuitiveness and interactivity of the file cabinet, allowing users to browse, judge, and perform preliminary processing without removing the physical documents, significantly improving retrieval and location efficiency. In addition, the projection operation buttons and storage compartment information provide an intuitive mapping of the location of the target document and the operations that can be performed, reducing the probability of mistaking, taking away, or misplacing documents, and improving security and traceability. Moreover, the high-precision light wavefront of the projection image and the synergy of the optical elements can adapt to documents of different sizes and attributes, possessing good scalability and fault tolerance.

[0020] Based on the above embodiments, in some modified embodiments, the filing cabinet may further include a touch sensing module, which is integrated with the holographic projection device and the file management server respectively; the touch sensing module is used to sense and recognize the user's touch operation on the projection operation button, generate a file operation request based on the touch operation, and send it to the file management server; the file service manager is used to perform the corresponding operation on the file based on the file operation request, and send the operation result to the holographic projection device; the holographic projection device is used to project the operation result in the form of holographic projection.

[0021] It should be noted that the operation result may include prompts indicating the outcome of the corresponding operation and information such as newly generated files; this application does not impose specific limitations. For example, if a user touches the copy button, the touch sensing module will detect the corresponding touch operation and generate a file copy request based on the touch operation, which will then be sent to the file management server. The file management server will perform the file copy operation based on the file copy request. If the copy is successful, a success message and the copied file will be sent to the projection device as the operation result. If the copy fails, a failure message will be sent to the projection device as the operation result, and the projection device will project the operation result in the form of a holographic projection.

[0022] By deeply integrating the added touch-sensing module with the holographic projection device and file management server, touching the projection operation button directly generates a corresponding file operation request. The file service manager on the file management server then executes the corresponding operation, and the operation result is projected out in holographic form through the holographic projection device. This enhances the intuitiveness and responsiveness of the interaction. Users can initiate operations and see the results instantly by touching the projection button, reducing reliance on external devices and improving the user experience. It also reduces the risk of accidental touches, misoperations, and unauthorized operations, forming a clear input-processing-output closed loop for easy access control and auditing. Furthermore, it enhances the traceability and security of the system, as operation requests, execution processes, and results can be recorded, queried, and audited, improving compliance and management levels. It reduces wear and tear and maintenance costs of physical buttons while improving the durability and hygiene of the cabinet. Finally, it enhances adaptability and scalability. The modular touch input, server processing, and projection output facilitate the addition of new operation types, permission models, and interface interaction methods in the future, improving overall cost-effectiveness and application flexibility.

[0023] Based on the above implementation, in some modified implementations, the holographic projection device can be installed on the top or side of the cabinet, or on the wall or ceiling of the space where the cabinet is located.

[0024] Placing holographic projection devices on the top, side, or wall and ceiling of a cabinet significantly improves the visibility and accessibility of the projected content, as well as the comfort and flexibility of human-computer interaction. Specifically: top or side projection positions typically offer a wider, unobstructed projection area, facilitating multi-angle viewing and improving retrieval and judgment efficiency. This position reduces the space occupied by the projected content on the front of the cabinet, enhancing its aesthetics and internal space utilization. Furthermore, changing the projection position increases layout flexibility, adapting to different sizes, shapes, and scene requirements, facilitating subsequent maintenance, upgrades, and personalized design. Simultaneously, top / side projection reduces the direct line of sight to the user, improving comfort and ergonomics, and reducing the probability of misperception and operational errors. Additionally, side or top projection facilitates protective design and dustproofing of the projection system, improving system durability and maintenance cost-effectiveness, and enabling consistent projection effects and system expansion in different environments.

[0025] Based on the above implementation, in some modified implementations, the holographic projection device is used to project the document preview content onto the surface of the cabinet, or the vertical wall on the same side of the cabinet, or a preset movable projection device in the form of holographic projection.

[0026] Specifically, when the holographic projection device is set on the top or side of the cabinet, the document preview content can be projected onto the vertical wall on the same side of the cabinet in the form of holographic projection, or a preset movable projection device can be used; when the holographic projection device is set on the wall or ceiling of the space where the cabinet is located, the document preview content can be projected onto the surface of the cabinet in the form of holographic projection. This application embodiment does not make specific limitations.

[0027] Furthermore, when the document preview content is projected onto the cabinet surface, the cover information of each document preview can be displayed precisely at the location of its corresponding storage compartment, allowing users to clearly see the actual content. Corresponding projection operation buttons are also displayed at the location of the document preview cover information, enabling users to quickly perform corresponding operations on the document and improving user convenience. In addition, when there is no document information in the cabinet's storage compartment, the corresponding projection area of ​​that storage compartment can be set to a preset color to distinguish the storage status of each projected storage compartment area.

[0028] It should be noted that when the file preview content is projected onto the surface of the cabinet, the file preview cover information can be the file icon plus the file name; when the file preview content is projected onto the wall or ceiling of the space where the cabinet is located, the file preview cover information can be the large icon of the file. Those skilled in the art can flexibly adjust according to the actual situation, and the embodiments of this application do not impose specific limitations.

[0029] By expanding the projection target of the holographic projection device to the cabinet surface, the vertical wall on the same side of the cabinet, or a pre-set movable projection device, the visibility, readability, and accessibility of the document preview content can be significantly improved by flexibly selecting the projection surface according to the usage scenario and user position. Multi-surface projection supports information sharing and simultaneous viewing in multi-person collaborative scenarios, improving the efficiency of retrieval, positioning, and decision-making, avoiding excessive occupation of the cabinet's front space, and improving the cabinet's aesthetics and space utilization. The movable projection device provides adaptive adjustment of projection distance, angle, and size, which can adapt to different document sizes, different ambient light conditions, and user heights, improving projection clarity and contrast, and enhancing the system's flexibility and scalability. By projecting information onto different surfaces, the reliance on physical touch controls is reduced, improving hygiene and operational intuitiveness, and facilitating quick switching between hidden and public information when needed.

[0030] Based on the above implementation, in some modified implementations, the filing cabinet further includes a user authentication module and a user information collection module. The user information collection module includes at least one of a face camera device, a fingerprint collection device, and a card reader. The user information collection module is disposed on the outer surface of the cabinet. The user authentication module is used to authenticate the identity of the target user based on the identity information collected by the user information collection module.

[0031] The newly added user authentication module and user information collection module, which are installed on the outer surface of the cabinet, can perform pre-authentication of documents entering the cabinet and users interacting with projection, thereby achieving stricter access control and operation authorization. Specifically, by supporting multiple identity information collection methods such as facial recognition, fingerprint recognition, and card recognition, the system provides multimodal and redundant identity authentication methods, improving the robustness and security of the file cabinet authentication. The user information collection device is placed on the outer surface of the cabinet, facilitating quick and intuitive information collection, reducing interference with the internal structure of the cabinet, and improving maintainability. The user identity verification module performs real-time identity authentication based on the collected information; only authenticated target users can perform operations such as projection viewing, file retrieval, modification, and deletion, significantly reducing the risk of unauthorized access and enhancing the protection of sensitive information. Deep collaboration with the file management server and holographic projection device enables the authentication results to be used to dynamically control projection content, operation permissions, and generate audit logs, improving traceability, auditability, and compliance. By supporting hierarchical permission configuration for different users or roles, multiple users can securely use the same cabinet concurrently, improving the system's flexibility and applicability. When authentication fails, the system provides immediate visual / audio prompts, reducing the probability of misoperation and improving user experience.

[0032] See Figure 2This application also provides a flowchart of a control method for a filing cabinet, which is applied to the filing cabinet provided in the above embodiments. The method specifically includes the following steps: Step 101: Based on the received file search keywords, obtain the file information of the file stored in the cabinet. Based on the file information, generate file preview content. The file preview content includes at least the file attribute information, file preview cover information, operation information, and storage compartment information of the file. The operation information indicates the supported operations to be performed on the file.

[0033] Step 102: Use the holographic projection device on the filing cabinet to project the document preview content in the form of a holographic projection.

[0034] This application embodiment improves retrieval efficiency and accuracy by generating a file preview based on the information of the files in the cabinet after receiving the search keywords, and then projecting and displaying the preview in holographic form using a holographic projection device. Because the preview includes file attribute information, cover information, executable operation information, and storage compartment information, users can quickly determine whether further processing is needed without opening the actual file, thereby enhancing the visibility and comprehension of the information. Holographic projection presents multi-dimensional information intuitively, facilitating quick understanding of the file status and available operations, reducing misjudgments, and minimizing physical operations and risks. The projected display replaces or reduces direct contact with the file, reducing the probability of wear, contamination, or accidental retrieval. Furthermore, the projected content can be viewed and discussed simultaneously by multiple users, promoting rapid consensus and improving collaboration and decision-making efficiency.

[0035] Based on the above implementation, in some modified implementations, it may further include: when the user triggers the file projection operation button, generating a file operation request, wherein the projection operation button is generated based on operation information and includes at least one of a copy button, delete button, modify button, open button, and retrieve button; and performing the corresponding operation on the file based on the file operation request.

[0036] When a user triggers a file projection operation button, the system can dynamically generate the projection operation button and file operation request based on the operation information. Based on this request, the system performs the corresponding operation on the selected file, improving the intuitiveness and responsiveness of the interaction. The projection interface automatically presents buttons for at least one operation, such as copy, delete, modify, open, or retrieve, based on the file's operation information. Users can directly perform the required operation through the projection interface, significantly reducing search time. Furthermore, the operation buttons and corresponding operation requests undergo permission verification and generate operation records through collaboration between the projection system and backend permissions, reducing the risk of unauthorized operations and improving traceability, thus enhancing security and compliance. Additionally, guiding users to perform operations through the projection interface reduces direct contact with physical files, lowering the probability of wear, contamination, or accidental access.

[0037] Based on the above implementation, in some modified implementations, before obtaining the file information of the files stored in the cabinet according to the received file retrieval keywords, the method further includes: obtaining the identity information of the target user using the file cabinet, the identity information including at least one of the target face image, target fingerprint, and card information; and authenticating the target user's identity based on the identity information.

[0038] Before retrieving file information from the cabinet based on received search keywords, authentication using multimodal identity information such as facial recognition, fingerprints, and card information enhances the robustness and flexibility of identity verification. The authentication results are linked to subsequent permission policies, limiting the scope of searchable files, displayed content, and the set of executable operations, further improving security. Moreover, unauthorized users cannot access file information, preview content, or projected content, significantly reducing the probability of unauthorized access to sensitive information and lowering the risk of information leakage. Furthermore, authentication results based on identity information enable tiered access for different users or roles, improving collaborative security and efficiency in multi-user environments, reducing the risks associated with the transmission and storage of sensitive biometric data, and enhancing privacy protection.

[0039] Based on the above implementation, in some modified implementations, the file preview content is projected in the form of holographic projection. Specifically, it may include: generating a light wavefront for the file preview content, generating a projection image based on the light wavefront and outputting it. The projection image includes at least the file preview cover information, projection operation buttons and storage compartment information for storing the file. The projection operation buttons include at least one of the following: copy button, delete button, modify button, open button and retrieve button.

[0040] The projected content preview simultaneously displays file attributes, cover information, executable operations, and storage compartment locations. Users can quickly determine whether further processing is needed without opening the actual file, significantly improving the speed and accuracy of retrieval and decision-making. Moreover, the projected interface displays operation buttons in three-dimensional space, allowing users to directly perform operations such as copying, deleting, modifying, opening, and retrieving within the projected area. This reduces the time cost of searching and switching interfaces, enhancing the intuitiveness and responsiveness of the interaction. Furthermore, presenting and executing operations through holographic projection effectively reduces direct contact with physical documents, lowering the probability of wear, contamination, or accidental retrieval, and protecting the security of sensitive or fragile documents.
