Description

Technical Field

[0001] This invention relates to the field of intangible cultural heritage technology, specifically to a digital display system and method for intangible cultural heritage. Background Technology

[0002] Intangible cultural heritage (hereinafter referred to as "ICH") is the core carrier of national culture, encompassing multiple categories such as traditional crafts, folk customs, and oral literature. Its transmission and display face challenges such as the perishability of physical objects, limited dissemination, and insufficient interactive experiences. Existing digital display technologies for ICH mostly focus on single-dimensional information presentation, such as photography, video recording, and 3D modeling, which have the following technical shortcomings: The perception dimension is singular, and it can only realize the one-way information transmission of vision or hearing, and cannot reproduce the multimodal sensory experience such as tactile feedback and olfactory characteristics in the operation of intangible cultural heritage skills; The existing systems suffer from insufficient adaptive capabilities. They mostly use fixed resolution and fixed display logic, which cannot dynamically adjust the displayed content and rendering accuracy according to the performance of terminal devices, network bandwidth and personalized user needs. The interaction is not deep enough. The existing interaction is mostly limited to simple operations such as clicking and dragging, which cannot realize immersive simulation operation and real-time error correction guidance of intangible cultural heritage skills, and cannot meet the needs of users for in-depth experience and inheritance learning. The data has low correlation, and the various elements of intangible cultural heritage are stored and displayed in a scattered manner without establishing multi-dimensional data correlation, which makes it impossible for users to form a complete understanding of intangible cultural heritage.

[0003] To address the aforementioned technical challenges, there is currently no digital display technology solution for intangible cultural heritage that can achieve multimodal perception fusion, dynamic adaptive rendering, deep interactive experience, and multi-dimensional data association. Therefore, developing a comprehensive, interactive, and adaptable digital display system and method for intangible cultural heritage has become an urgent need in the field of intangible cultural heritage protection and digital dissemination. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a digital display system and method for intangible cultural heritage, which realizes the comprehensive collection of multimodal information of intangible cultural heritage, dynamic adaptive display, immersive interactive experience and multi-dimensional data association, thereby improving the efficiency of inheritance and dissemination of intangible cultural heritage.
