Solution Overview

Problem

Existing virtual conferencing systems do not provide an efficient way for participants in one room to preview another room in real-time without switching to that room.

Innovation Solution

The system introduces a room preview element that displays a live video-audio feed of a second room as a window within the first room, with audio output from the second room at a reduced level relative to the first room.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If participants switch to another room to preview it, then they can observe the room content, but they leave their current room and interrupt ongoing communication

Engineering Contradiction:
Improveroom preview capabilityVSAvoidnavigation convenience
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The system creates a visual copy (picture-in-picture window) of the second room's video feed and displays it within the first room's interface. This allows participants to observe the second room's content without actually navigating there, resolving the contradiction by providing preview capability while maintaining presence in the current room.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The interface is segmented into multiple viewing areas, with the main room view occupying the primary space and the preview room view displayed as a separate window or picture-in-picture overlay. This segmentation enables simultaneous viewing of both rooms, allowing participants to preview without leaving their current room.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If audio from the second room is played at full level, then participants can hear room conversations clearly, but it interferes with audio from the first room

Engineering Contradiction:
Improveaudio clarityVSAvoidaudio interference
Core Design Contradiction:
Loss of informationVSObject-generated harmful factors

Solution Approach 1:

Different audio quality levels are applied to different sources: the primary room's audio maintains full quality and volume for clear communication, while the preview room's audio is played at a reduced, background level. This local differentiation of audio quality resolves the contradiction by providing sufficient audio clarity for previewing while preventing interference with the primary room's communication.

Inventive Principle:
Principle #3Local quality

AI summary

Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing a program and method for providing a room preview within a virtual conferencing system. The program and method provide for virtual conferencing between plural participants within a first room of plural rooms, the plural rooms being included within a virtual space for virtual conferencing; and for each of the plural participants, provide a first audio channel associated with audio output of the first room, provide display of a room preview element within the first room, the room preview element corresponding to a live preview of a second room of the plural rooms, and provide a second audio channel associated with audio output of the second room.
