Abstract

Abstract:

Holographic technology possesses the unique capability for true three-dimensional display, aiding in providing vivid and accurate visual perception and natural interactive experiences. In the future, it will have extensive practical applications in image and information presentation-related aspects. In addition, with the development of geographic information and the universal application of maps, maps have become a very important tool for the public. Among them, holographic maps of large public places demonstrate a wide range of demands and high application value, and its inherent characteristics of information fusion and information bearing also render its presentation form of profound research significance. Firstly, the information display features of holographic maps in large public places were analyzed from the perspectives of map content, spatial characteristics, and interactive characteristics, and the mapping methods and information hierarchy were studied through experiments.The experimental results revealed that the basic scene layer was optimally presented through spatial perspective locking. The associated ubiquitous information layer was best presented via user perspective locking, and its information hierarchy applied to the spatial-depth architectural scheme. Based on the conclusions, combined with the scene characteristics and user demands of large public spaces, the design practice of holographic map systems in large public places was undertaken, offering certain reference and inspiration for the adoption and application of holographic technology.

Key words: holographic map, information interaction, spatial reference system, user perspective, information hierarchy, spatial layout
