Immersion-Aware Content Switching Using Biometric Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle content output systems fail to promptly adjust content to match user preferences or moods, leading to discomfort and potentially reduced traffic safety.
Innovation Solution
A content output control device that acquires biological information to recognize a degree-of-immersion reduction state and switches content output to better match user preferences, including audio-only content when video is not engaging, and prompts user responses to determine desired content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content is continuously output from the content output device, then the user can be entertained, but the user may experience discomfort when the content does not match their preference or mood
Solution Approach 1:
The system continuously monitors the user's biological information (heart rate, body temperature, perspiration level) and uses this feedback to determine the user's mood state. Based on this feedback, the system automatically adjusts the content output to match the user's current mood, resolving the contradiction between continuous content output and user comfort by making the content adaptive rather than static
Solution Approach 2:
The content output system transitions from a static state to a dynamic state by continuously adjusting the content based on real-time mood recognition. The system can switch between different content types (video, audio, both, or none) depending on the user's mood, making the content delivery flexible and adaptive to changing user needs
2Measurement precision
If the system waits for user feedback to switch content, then content accuracy can be improved, but the response time is delayed
Solution Approach 1:
The system performs preliminary mood assessment continuously in the background using biological information sensors, so that when content switching is needed, the decision can be made immediately based on already-collected data. This eliminates the delay of waiting for explicit user feedback while maintaining high accuracy in content matching
3Ease of operation
If the system switches content frequently, then user comfort can be improved, but system complexity increases
Solution Approach 1:
The system changes the parameters of content output (type, volume, presence) based on mood recognition results. By using a standardized mood recognition framework and predefined content switching rules, the system achieves high adaptability without requiring complex decision-making algorithms, thus managing system complexity while improving content adaptability

AI summary
A content output control device includes: a degree-of-immersion reduction state recognition unit configured to recognize, based on biological information, that a user is in a degree-of-immersion reduction state indicating that a degree of immersion with respect to content output from a content output device is reduced; and an output content switching unit configured to execute content switching processing of switching, while first content is output from the content output device, when the user is recognized to be in the degree-of-immersion reduction state, the content output from the content output device to second content that is different from the first content.
