Solution Overview

Problem

Conventional teleconference systems require users to directly operate shared terminals, such as electronic information boards, which is inconvenient for participants during events like online meetings.

Innovation Solution

A text data transmission-reception system that includes user terminals and a shared terminal connected via a network, with circuitry to determine and execute control requests for the shared terminal based on received text data, allowing remote operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If users directly operate shared terminals at the conference room, then control accuracy is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvecontrol accuracyVSAvoidease of operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent introduces a collaboration tool as an intermediary between the user and the shared terminal. The user operates the shared terminal remotely through the collaboration tool via network communication, eliminating the need for physical presence at the conference room while maintaining control functionality. This mediator enables users to perform operations like screen sharing, file transfer, and terminal control from remote locations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If users remotely control shared terminals via text commands, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The collaboration tool serves multiple functions: it manages text data transmission, interprets control commands, establishes network connections, and coordinates between multiple user terminals and the shared terminal. By consolidating these diverse functions into a single multi-functional platform, the system avoids the complexity that would arise from implementing separate specialized systems for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A text data transmission-reception system includes a plurality of user terminals; a shared terminal; and an information processing apparatus connectable to each of the plurality of user terminals and the shared terminal via a network. The information processing apparatus includes circuitry configured to receive text data transmitted and received between the plurality of user terminals; determine whether or not the text data transmitted and received between the plurality of user terminals includes a request for controlling the shared terminal; and control the shared terminal based on a determination that the text data includes the request for controlling the shared terminal.
