Notification Device Prioritizing Content Importance for Moving Body Passengers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for notifying passengers on a moving body with automated driving do not effectively prioritize notification content by importance, potentially annoying passengers with non-essential information and failing to draw attention to critical safety messages.
Innovation Solution
A device and method for controlling the output of notification content to a moving body passenger, utilizing an information processing device that assesses the degree of importance of notification content and passenger-specific information to determine the appropriate output destination, such as a moving-body-mounted output device or a communication device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all notification contents are transmitted to passenger mobile terminals, then information completeness is improved, but passenger annoyance increases and attention to critical content decreases
Solution Approach 1:
The patent applies local quality by differentiating notification delivery based on content importance level. Critical notifications (high importance) are delivered to all passengers via both in-vehicle displays and mobile terminals, while non-critical notifications (low importance) are selectively delivered only to passengers who have opted in. This selective quality assignment resolves the contradiction by ensuring complete delivery of essential information while reducing unnecessary notifications that cause annoyance.
Solution Approach 2:
The notification system segments content into different importance levels (critical and non-critical). This segmentation allows the system to apply different delivery strategies: critical notifications are universally delivered through multiple channels, while non-critical notifications are selectively delivered based on passenger preferences. The segmentation principle directly addresses the contradiction by separating notifications that must reach all passengers from those that should reach only interested passengers.
2Loss of information
If all notification contents are transmitted to all passengers, then information completeness is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary action by pre-classifying notification contents into importance levels and pre-storing passenger notification preferences before actual notification delivery. The information processing device maintains a database of passenger preferences and notification templates categorized by importance. When a notification needs to be sent, the system retrieves pre-defined delivery rules based on the notification's importance level and passenger preferences, avoiding complex real-time decision-making and simplifying the output control process.
Solution Approach 2:
The information processing device acts as an intermediary between the notification source and passenger terminals. It receives notifications, classifies them by importance, checks passenger preferences, and determines the appropriate delivery method. This intermediary layer simplifies the overall system by centralizing the decision-making logic in one component, rather than requiring complex coordination between multiple systems to determine what each passenger should receive.

AI summary
A device for notification to a moving body passenger includes an information processing device, a moving-body-mounted output device configured to output the notification content, and a communication device configured to transmit the notification content to a device carried by the passenger. The information processing device includes a storage device in which travel information, passenger information and information about a notification content list, and a processor. In the output control process, the processor identifies a control target content indicating the notification content to be targeted by the output control, based on the travel information and the information about the notification content list or based on the travel information, the passenger information and the information about the notification content list, and outputs the control target content to the moving-body-mounted output device if it is determined that a degree of importance of the control target content is at or above a predetermined level.
