Display Audio Control for Directing Attention to Sub-Content

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing display systems struggle to effectively draw attention to sub-content without obstructing the viewing of main content.

Innovation Solution

A display system comprising a display, multiple speakers, and a control device that simultaneously displays main and sub-content, with the control device temporarily stopping sound output from specific speakers to direct user attention to sub-content without obstructing the main content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sound is output from all speakers to maintain immersive audio experience, then audio quality is improved, but attention to sub-content is reduced

Engineering Contradiction:

Improveaudio qualityVSAvoidattention direction

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts speaker output based on the user's selected sub-content area. When sub-content is displayed, the control device stops sound output from speakers on the side closer to the sub-content, creating a dynamic audio environment that adapts to the user's attention needs while maintaining overall audio quality

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Different speakers have different output states based on their spatial relationship to the sub-content. Speakers closer to sub-content are muted while other speakers continue normal output, creating local quality differences in sound distribution to guide user attention without compromising overall audio experience

Inventive Principle:

Principle #3Local quality

2Loss of information

If sub-content is displayed to provide additional information, then information completeness is improved, but obstruction of main content viewing occurs

Engineering Contradiction:

Improveinformation completenessVSAvoidviewing obstruction

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The display is divided into multiple areas: a first display area for main content and second/third display areas for sub-content. This segmentation allows simultaneous display of both main and sub-content without mutual obstruction, as each area is spatially separated and dedicated to specific content types

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Sub-content is displayed in peripheral areas (second display area at first end portion, third display area at second end portion) rather than overlapping with main content. This spatial arrangement in different display dimensions allows both main and sub-content to be viewed simultaneously without obstruction

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A display system includes a display, a plurality of speakers, and a control device that controls the display and the speakers. The display is configured to be able to simultaneously display video of main content and video of sub-content. The speakers are configured to output sound of the main content. The control device is configured to stop output of sound from a speaker on a side closer to the sub-content when video of the sub-content is desired to attract a user.
