Solution Overview

Problem

Conventional video conference systems often present participants as individual tiles on a screen, leading to confusion and rapid loss of concentration, especially when the number of participants is large or the focus shifts between speakers.

Innovation Solution

Reproduce videos of multiple participants on spatially arranged video reproduction areas or spaces within a three-dimensional virtual reality environment, allowing users to adjust their viewpoint and viewing direction, mimicking a real-world conference setting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If videos of multiple participants are arranged as individual tiles on a screen, then all participants can be displayed, but user concentration is lost rapidly and the experience becomes confusing

Engineering Contradiction:
Improvenumber of participants displayedVSAvoiduser concentration and engagement
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent transitions from a two-dimensional flat tile arrangement to a three-dimensional spatial virtual reality environment. Video reproduction areas are positioned in 3D space with depth, width, and height dimensions, allowing participants to be arranged naturally as if sitting around a table. This dimensional change enables users to focus on specific participants by directing their gaze in different directions while maintaining awareness of all participants, thus solving the contradiction between displaying multiple participants and maintaining user concentration.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If the number of participants is large, then more people can join the conference, but some participants are not presented or perception changes depending on the current speaker

Engineering Contradiction:
Improvenumber of participantsVSAvoidvisibility of all participants
Core Design Contradiction:
Quantity of substanceVSLoss of information

Solution Approach 1:

By arranging video reproduction areas in a three-dimensional virtual reality space, the system can accommodate a large number of participants without occluding any views. The spatial distribution allows all participant videos to be simultaneously visible from the observer's viewpoint, eliminating the need to hide participants when the group size increases. The 3D environment provides sufficient spatial volume to position multiple video areas without overlap or obstruction.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent implements different spatial positions and orientations for different video reproduction areas within the 3D environment. Each participant's video is placed at a specific location with appropriate orientation, creating localized viewing zones. This allows the observer to naturally focus on different participants by looking in different directions, ensuring all participants remain visible and accessible without forcing a single perception mode.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If videos are arranged in a planar seminar room layout, then fixed seats are provided, but the arrangement remains two-dimensional and lacks realism

Engineering Contradiction:
Improvefixed seat arrangementVSAvoidrealism and natural interaction
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent enhances the fixed seat arrangement by positioning video reproduction areas in a three-dimensional virtual reality space that mimics a real conference room with a round table. The observer can be positioned at a fixed viewpoint while video areas are distributed in 3D space around the table, creating a realistic spatial arrangement that provides both structure and natural interaction. This allows participants to be arranged in a circular pattern that feels more authentic than a flat grid layout.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
