AR Device Marker-Based Object Sharing via Server Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional AR information sharing systems face issues such as long data transmission times, instability due to large data volumes, and compatibility limitations between different AR programs, particularly in peer-to-peer setups, which hinder efficient sharing of AR objects across devices.
Innovation Solution
An AR device and system that uses a marker-based approach to share AR objects by projecting a marker onto the real world, allowing for the transmission of marker identification information and corresponding AR object data, rather than entire map data, enabling efficient and compatible sharing across devices with different AR programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If map data and anchor data are transmitted to share AR objects between devices, then AR object sharing is enabled, but data transmission time increases and connection stability deteriorates
Solution Approach 1:
The patent extracts only the essential marker identification information from the complete map data, transmitting only what is necessary for AR object sharing. This reduces the data volume from entire map datasets to compact marker IDs, directly resolving the contradiction between enabling AR sharing and reducing transmission time.
Solution Approach 2:
The patent introduces a server as an intermediary that stores map data and anchor data centrally. Devices communicate marker IDs through the server rather than transmitting complete map data peer-to-peer, which reduces transmission time while maintaining full AR sharing functionality.
2Adaptability or versatility
If map data is transmitted for AR sharing, then AR objects can be shared, but connection stability worsens due to large data volumes
Solution Approach 1:
The patent extracts only marker identification information from complete map data, transmitting minimal data necessary for AR object sharing. This extraction principle reduces data volume and eliminates the connection stability issues caused by large data transmissions.
Solution Approach 2:
The server acts as an intermediary that handles large map data storage and retrieval, allowing devices to exchange only small marker IDs. This mediator approach isolates devices from the burden of handling large data volumes, maintaining connection stability.
3Ease of operation
If conventional P2P scheme is used for AR sharing, then direct device communication is enabled, but device complexity increases due to software compatibility requirements
Solution Approach 1:
The patent introduces a server as an intermediary that handles the complexity of map data management and software compatibility. Devices only need to communicate simple marker IDs through the server, eliminating the need for complex P2P software compatibility arrangements while maintaining direct communication capability.
4Loss of time
If marker-based approach is used instead of map data transmission, then data transmission time is reduced, but AR sharing functionality may be limited
Solution Approach 1:
The server intermediary stores complete map data and anchor data, enabling marker-based quick transmission while maintaining full AR sharing functionality. When devices exchange marker IDs, the server provides the corresponding complete data, resolving the contradiction between fast transmission and functional completeness.
