Multi-Display Notification Control for In-Vehicle Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices in vehicles face challenges in managing large information amounts, leading to reduced visibility and incomplete information notification due to excessive display of information, especially in multi-display environments.
Innovation Solution
A display control device that determines when the information amount on a first display exceeds a threshold, causing a second display to show detailed information while the first display shows simplified information, with relevance indicators to connect the two.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all notification information is displayed on a single display device, then complete information notification is achieved, but visibility is reduced due to excessive information amount
Solution Approach 1:
The notification information is segmented and distributed across multiple display devices based on information amount thresholds. When the first display device detects that the information amount exceeds a threshold, it transfers part of the notification information to a second display device, thereby segmenting the information display task to maintain visibility on each individual display while ensuring complete information notification across the system.
2Illumination intensity
If simplified information is displayed on the first display device, then visibility is maintained, but information completeness is reduced
Solution Approach 1:
The system introduces a second display device as an intermediary to handle detailed notification information. When the first display device determines that information amount exceeds the threshold, it maintains simplified display for visibility while the second display device supplements the detailed information, acting as an intermediary that bridges the gap between visibility requirements and information completeness.
3Illumination intensity
If multiple display devices are used to distribute information, then visibility is maintained, but device complexity increases
Solution Approach 1:
The first display device performs self-service by autonomously determining whether to transfer notification information to the second display device based on its own information amount threshold. This self-service mechanism reduces the need for complex centralized control, as each display device can independently assess its own state and make decisions about information distribution, thereby reducing overall system complexity.

AI summary
A display control device includes: a determiner that determines whether an information amount of first display information displayed on a first display device is greater than or equal to a predetermined threshold value; and a controller that (i) causes the first display device to display the first display information and first notification information about a predetermined event, and (ii) causes a second display device to display second notification information about the predetermined event, when the determiner determines that the information amount of the first display information is greater than or equal to the predetermined threshold value, the second display device being different from the first display device, the second notification information including the first notification information and having an information amount larger than an information amount of the first notification information.
