Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electronic conference systems face usability issues due to the need for users to manually switch between shared and unshared layers for drawing, leading to decreased user-friendliness as images shared and not shared are displayed and managed separately, but with fixed sizes and positions, making it difficult to draw images separately on each layer.

Innovation Solution

An image sharing method and system where a first information processing device transmits and displays objects drawn on a shared layer to a second device while not transmitting and displaying objects drawn on an unshared layer, allowing variable control of the size and position of the unshared layer, enabling separate and seamless drawing on both layers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate shared and unshared layers are used for drawing, then image sharing functionality is improved, but user operation complexity increases due to manual switching requirements

Engineering Contradiction:

Improveimage sharing functionalityVSAvoiduser operation complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The drawing area is segmented into shared and unshared layers, allowing independent management of shared and private content. This segmentation enables the system to distinguish between content that should be transmitted to other devices and content that should remain local, resolving the contradiction by providing clear functional separation without requiring manual switching operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent merges the shared and unshared layers into a single integrated drawing interface where both layers coexist simultaneously. Users can draw on both layers without leaving the same interface, eliminating the need to manually switch between separate modes while maintaining the functional benefits of content separation.

Inventive Principle:

Principle #5Merging (Combining)

2Stability of the object's composition

If fixed size and position are used for layers, then system stability is improved, but drawing flexibility deteriorates

Engineering Contradiction:

Improvelayer stabilityVSAvoiddrawing flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The unshared layer is designed with dynamic properties, allowing its size and position to be adjusted freely by users during the drawing process. This dynamic capability enables users to optimize the layer configuration for different drawing scenarios while the shared layer maintains stability, resolving the contradiction between fixed composition and flexible adaptation.

Inventive Principle:

Principle #15Dynamics

AI summary

An image sharing method for sharing an image between a first information processing device and a second information processing device includes: when a first drawing is executed on a shared layer shared with the second information processing device, causing the first information processing device to transmit a first object generated by the first drawing to the second information processing device; when a second drawing is executed on an unshared layer not shared with the second information processing device, causing the first information processing device not to transmit a second object generated by the second drawing to the second information processing device; and causing the first information processing device to variably control one of a size and a position within the screen of the unshared layer, or both of the size and the position within the screen of the unshared layer.
