Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Electronic devices cannot effectively estimate and incorporate user emotional information into content, such as photos and videos, limiting their ability to provide personalized services.

Innovation Solution

Incorporating a dual-camera system in electronic devices to capture and analyze user emotional data, which is then added to content as emotional tags or metadata, allowing for personalized service enhancements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If emotional information is extracted from content such as photos, then the electronic device can provide services using emotion, but the device cannot estimate emotion when no person or animal exists in the content

Engineering Contradiction:

Improveservice capability using emotional informationVSAvoidemotion estimation accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a camera as an intermediary device to capture the user's emotional state separately from the content being viewed. The camera captures images of the user's face, and emotion recognition algorithms analyze these images to determine emotional information, which is then associated with the content. This mediator approach allows emotion estimation even when the content itself does not contain recognizable subjects.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the electronic device cannot estimate user emotion from photos, then service personalization is limited, but adding camera functionality increases device complexity

Engineering Contradiction:

Improvepersonalized service capabilityVSAvoidcamera system integration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent leverages the camera's existing functionality for capturing images and extends it to serve dual purposes: traditional photography and emotion recognition. By processing camera-captured images through emotion analysis algorithms, the same hardware component performs multiple functions, reducing the need for additional specialized devices and minimizing the impact on device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If emotional information is added to content, then user experience is enhanced, but processing and storing emotional metadata increases system complexity

Engineering Contradiction:

Improveuser experience qualityVSAvoidemotional metadata processing

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts emotional information as separate metadata from the content itself. Rather than modifying the original content files, the system captures emotional states, processes them independently through recognition algorithms, and stores them as associated metadata. This separation allows the content and emotional information to be handled independently, simplifying processing and storage requirements.

Inventive Principle:

Principle #2Taking out (Extraction)
