In-Vehicle Content Output Control for Passenger Viewing Restrictions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to output content in vehicles accommodating multiple passengers with varying ages and access credentials, failing to consider individual preferences and viewing/restriction requirements effectively.
Innovation Solution
A content output device and method that identifies individual passengers, determines content output permissions based on age and access restrictions, and suggests alternative content or seat adjustments to accommodate individual preferences while adhering to viewing and access restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content is output according to individual passenger preferences, then passenger satisfaction is improved, but viewing restrictions and access restrictions cannot be properly enforced
Solution Approach 1:
The system segments the passenger group into individual users, each with their own identification information and access credentials. By identifying each passenger separately and checking their specific access rights, the system can enforce restrictions reliably while still accommodating individual preferences through personalized content selection within their authorized ranges.
Solution Approach 2:
The content output device acts as an intermediary between the content source and passengers. It mediates by checking access credentials, verifying viewing restrictions, and filtering content based on individual passenger authorization. This intermediary function ensures restrictions are enforced while still providing personalized content access to each passenger.
2Reliability
If content output is restricted based on viewing restrictions and access credentials, then restriction compliance is improved, but passenger preferences and content selection freedom deteriorate
Solution Approach 1:
The system applies different access rights and content permissions to different passengers based on their individual credentials. Each passenger receives content selection freedom appropriate to their local authorization level, rather than applying a uniform restriction policy to all passengers. This allows the system to maintain high restriction compliance while preserving content selection freedom for each passenger within their authorized scope.
3Measurement precision
If the system identifies and checks each passenger's access credentials, then restriction accuracy is improved, but system complexity and processing time worsen
Solution Approach 1:
The system performs preliminary identification and credential verification of passengers before content output. By checking access credentials and determining viewing permissions in advance, the system ensures accurate restriction enforcement without adding complexity to the actual content delivery process. The identification and authorization checks are completed beforehand, so the content output itself remains straightforward.
Data Source
AI summary
A content output device includes an output unit configured to output, as target content, content designated by a passenger of a mobile object to a display device, an identification unit configured to acquire identification information regarding content viewing for each passenger seated on each seat of the mobile object, a determination unit configured to determine whether or not to permit output of the target content by the output unit on the basis of the identification information and restriction information regarding viewing of the target content, and a suggestion unit configured to make a suggestion related to output of content to a passenger. When the determination unit determines not to permit the output of the target content, the suggestion unit suggests, to the passenger, alternative content to the target content or a countermeasure for permitting the output of the target content.
