다국어 초록 (Multilingual Abstract)

This paper is a study that visually structures and examines the relationship between the concepts of metaverse and multimodality, exploring their directions for development. To achieve this, a literature review of the past 20 years was conducted as the main source of information.
And after examining the definitions and properties of key terms, collect, compare, and analyze related concepts and cases that appear in the direction of technology. Afterwards, limitations and improvements are compared and their relationships are analyzed by structuring them into a visual conceptual model. To confirm the structural concept of multimodality, the meaning of the dictionary definition of system and interface is analyzed, and based on this, the inputs and outputs composed of actual interactions are interpreted based on the system. By collecting and analyzing the definition, properties, and direction of the metaverse, it is classified into the real world, agents, and, virtual space. The metaverse is classified into three attributes: foundation, system, and operation, and then all classified information is compared with the four types of metaverse presented by the Acceleration Research Foundation and presented as a conceptual model. The paper also Analyzes the limitations that appear when extended reality technology is applied to the metaverse so that virtual space and physical reality can be naturally connected based on technology. By categorizing them into three categories, we present the limitations of hardware from the developer’s perspective, physical concentration limit from the user’s perspective, and cost and facility limits from the operator’s perspective. Following the analysis of these limitations, the paper discusses the utilization of multimodality technology based on extended reality and Metaverse access devices that can easily check external conditions. In addition, it considers the possibility of creating new opportunities through the sharing of devices and services through cooperation between competing companies.
