Vehicle Warning Display Control for Multi-Screen Driver Attention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with multiple displays, drivers may not adequately recognize critical warning information due to distributing their attention across displays, leading to potential missed warnings during hazardous situations.
Innovation Solution
An information presentation device that prioritizes the display of notification information on a head-up display while temporarily stopping other displays, ensuring the driver's attention is focused on critical warnings by using a control unit to manage display areas and conditions for notification presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple displays are used inside a vehicle, then information can be presented to the driver through multiple channels, but the driver's attention is distributed across displays, reducing visual recognition of critical warning information
Solution Approach 1:
The system dynamically adjusts display states based on situation urgency. When a critical situation is detected, the notification display transitions from a static state to an active warning state, while other displays transition from active to inactive states. This dynamic reconfiguration ensures that critical warnings receive full attention while maintaining normal multi-display operation during non-critical periods.
Solution Approach 2:
The system implements periodic assessment of situation urgency and display states. The control unit continuously monitors whether critical situations exist and periodically adjusts display states accordingly. This periodic action ensures that the driver's attention is redirected to critical warnings when needed while maintaining normal information presentation during safe periods.
2Ease of operation
If display position changes according to user's visual line, then information can be presented at the user's focus point, but the driver may not memorize information and display position association, causing confusion
Solution Approach 1:
The system extracts critical warning information from the dynamic visual line-based display system and presents it on a dedicated notification display with fixed position. This extraction ensures that critical warnings are separated from the changing display positions, allowing drivers to reliably associate warning information with a consistent location while still benefiting from visual line-based presentation for non-critical information.
3Loss of information
If notification information is displayed on one display while other displays continue operating, then comprehensive information is available, but the driver may miss critical warnings due to attention distribution
Solution Approach 1:
The system segments display functions into two categories: critical warning presentation and general information display. When a critical situation is detected, the notification display is dedicated exclusively to warning information while other displays are inhibited. This segmentation ensures that critical warnings receive undivided attention while general information remains available during non-critical periods.
Solution Approach 2:
The system takes preliminary anti-action by inhibiting other displays before critical warnings could be missed. When a critical situation is detected, the control unit proactively stops other displays from operating, preventing the driver's attention from being divided. This preliminary action ensures that critical warnings are immediately recognized without competition from other information.

AI summary
In order to provide a technology enabling efficient visual recognition of notification information by a user, provided is an information presentation device, including: a display adjustment unit configured to display, using processing information for displaying information based on a start condition, the information on a plurality of display areas; and a storage unit configured to store condition information associating a predetermined start condition with notification information being the information to be displayed when the predetermined start condition occurs, in which the display adjustment unit is configured to, when satisfaction of the predetermined start condition is detected: identify the display area for displaying the notification information that is associated with the predetermined start condition in the storage unit; cause display of the notification information on the display area; and restrict display on other display areas other than the display area.
