Screen Sharing Event Control Across Multiple Display Terminals

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing screen sharing systems are inconvenient for devices other than the designated screen sharing destination, as they lack control over shared display screens.

Innovation Solution

An information processing device that generates screens for multiple terminals, detects user operations, and allows users to select whether to execute events based on these operations through a selection screen, determining event execution based on user input.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the screen is controlled by a single screen sharing destination device, then the control simplicity is improved, but the convenience for other devices deteriorates

Engineering Contradiction:

Improvecontrol simplicityVSAvoidconvenience for other devices

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The patent implements dynamic role assignment where devices can switch between initiator and responder roles based on which device performs the operation. The system dynamically determines control rights by detecting which device initiates an operation, allowing the control relationship to adapt rather than being fixed to a single destination device

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent establishes predetermined rules for handling operations from non-initiator devices. Before conflicts occur, the system has predefined logic that determines how operations from different devices should be handled, including the selection screen mechanism that prepares for potential control conflicts in advance

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If operations from any device are executed, then the ease of operation is improved, but the reliability of screen sharing control deteriorates

Engineering Contradiction:

Improveoperation freedomVSAvoidscreen sharing control

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system implements feedback by detecting which device initiated an operation and using this information to determine whether to execute the operation. The selection screen provides feedback to users about whose operation will be executed, allowing informed decisions about operation execution based on the initiator identity

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The selection screen acts as an intermediary mechanism between operation detection and execution. It mediates by presenting the operation request to users and allowing them to decide whether to permit execution, thus controlling the flow between operation input and system response

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An information processing device maintains the convenience of other devices even when requested by one screen-sharing destination device. A screen generation unit generates the screen to be displayed on a first display. The transmission/reception control unit transmits the screen to the external terminals. The operation detection unit detects a user operation performed on a screen displayed on a second display unit provided by the external terminals. The display control unit controls the display of a selection screen to a device selected from the information processing device and the external terminals in order to allow the user to select whether or not to allow execution of an event based on the operation in response to the screen and operation. The event execution determination unit determines whether to permit execution of an event based on an operation in response to the result of selection by a user on the selection screen.
