Description

Farming and nomadic digital symbol interaction experience system Technical Field The invention relates to the technical field of digital cultural heritage processing and man-machine interaction, in particular to a farming and nomadic digital symbol interaction experience system. Background In the field of protection and display of digital cultural heritage, the digital processing of historical symbols (such as oracle, inscription on pottery, totem-pole, etc.) mainly focuses on high-precision image acquisition and three-dimensional modeling, and metadata is managed through a relational database. In the terminal interaction level, the existing display system generally adopts static graphic typesetting or simple drag interaction based on a general physical engine, and is used for presenting the appearance and basic information of the symbol to a user. However, the prior art has certain limitations in processing historical data with complex evolution features. The evolution of human civilization often presents continuously changing features, such as a significant gradual process of social rules and spatial logics when transitioning from free-flowing morphology of nomadic culture to orderly organized morphology of farming culture. The existing data classification method adopts a discrete binary label system to forcedly divide symbols into single attribute categories, and the rigid division mode cuts off the logic association between different civilized forms, so that the intermediate state of the characterization symbols in an evolution pedigree is difficult to quantify. In terms of interactive logic and space construction, existing visualization engines typically employ a single physical constraint framework. For example, either a strict grid layout is employed to accommodate structured data or a free force directed layout is employed to expose the associated network. The prior art lacks a method capable of dynamically adjusting a space constraint mechanism according to the intrinsic attribute of data, so that the bit value grid constraint required by farming civilization and the free manifold interaction required by nomadic civilization are difficult to be compatible in the same interaction viewport. In addition, when the operation behavior generated by the user in the interaction process collides with the historical logic rules, the existing system is mostly dependent on text prompt or simple logic blocking as a feedback means. The processing mode can not establish a direct mapping channel between a logical operation result and a bottom layer physical parameter or a graphics rendering state, and a user can not perceive deep evolution rules behind data and structural conflicts through visual force feedback or visual morphological changes. Disclosure of Invention Aiming at the defects of the prior art, the invention provides a farming and nomadic digital symbol interactive experience system, which solves the problems that the conventional digital cultural heritage display technology generally processes historical symbols into static discrete data points and lacks a calculation model capable of quantitatively representing continuous evolution relations between different social organization forms (such as farming ordered structures and nomadic free structures). The existing system cannot be compatible with free interaction of gridding rule constraint and manifold in the same interaction space, and is also difficult to convert abstract historical logic conflict into visual physical feedback or visual state in real time, so that a user cannot perceive the problem of evolution rule and structural difference behind data. The invention provides a farming and nomadic digital symbol interaction experience system, which comprises an attribute propagation module, a correlation calculation module, a manifold evolution engine and a self-adaptive rendering module. The attribute propagation module is used for calculating a tissue form attribute value of an unlabeled symbol sample based on a known label of an anchor point set through mixing characteristic distance measurement and manifold propagation algorithm, wherein the tissue form attribute value is a normalized value and is used for representing a continuous pedigree state of a symbol between a farming ordered system and a nomadic free system. The association calculation module is used for calculating association weights among the symbols based on the multidimensional features of the symbols and the organization form attribute values, and constructing an association map containing time sequence evolution relations. The manifold evolution engine is used for constructing a mixed potential energy field formed by superposition of grid adsorption potential energy and free interaction potential energy, takes a tissue form attribute value as a weighting variable, dynamically adjusts spatial stress parameters of the symbol on an interaction plane, and calculates a motion track of
