Solution Overview
Problem
Existing multi-user conferencing systems rely on video data transmission, resulting in high network traffic demands and storage costs due to large data amounts.
Innovation Solution
A multi-user conferencing system utilizing an infrared device with a network setting module, infrared ray position detecting module, and data processing module to transmit conference content based on non-image data, where the infrared device is placed on a writing medium to capture coordinate information of writing objects and send processed data to a cloud server for reproduction by terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video conferencing systems transmit data based on image or video, then conference content can be reproduced visually, but network traffic demand and storage requirements increase significantly
Solution Approach 1:
The patent extracts only the essential coordinate information from the writing process rather than transmitting complete video or image data. By capturing only the position coordinates of the writing object and excluding redundant visual data, the system achieves conference content reproduction while dramatically reducing network traffic and storage requirements.
Solution Approach 2:
The system creates a simplified copy of the writing content through coordinate data rather than copying actual video or image data. This coordinate-based representation serves as an efficient proxy that preserves the essential information needed for conference reproduction without the bulk of visual data.

3Ease of operation
If conventional writing tools and mediums are used, then user experience is maintained, but data transmission efficiency is reduced
Solution Approach 1:
The patent replaces the mechanical/optical system of capturing writing with traditional cameras or scanners with an infrared-based coordinate detection system. The infrared device detects the position of writing objects through infrared ray blocking, converting the mechanical writing action into digital coordinate data that can be efficiently transmitted and reproduced.
