Vehicle Display Region Control for Visual Distraction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems for vehicles do not effectively manage the display of virtual images based on changing traffic conditions and predicted vehicle directions, leading to inefficient use of display space and user experience.
Innovation Solution
A control device that determines display regions to transition from a display state to a non-display state based on traffic signals, predicted vehicle turns, and speed, using a processing unit to manage the display device and adjust the display according to predetermined conditions, such as changing traffic signals and automatic driving levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display device continuously displays virtual images in the foreground, then the user experience and information visibility are improved, but visual distractions during driving increase and safety decreases
Solution Approach 1:
The display device dynamically adjusts its operation based on detected conditions. When the vehicle is stationary or moving slowly, the display shows virtual images in the foreground. When the vehicle exceeds a threshold speed, the display transitions to showing only in the background, eliminating visual distractions while maintaining information availability.
Solution Approach 2:
The system changes the display parameter (foreground vs. background) based on the vehicle speed parameter. This parameter change resolves the contradiction by adapting the display behavior to the current driving conditions, ensuring safety at high speeds while maintaining usability at low speeds.
2Adaptability or versatility
If the display device manages multiple display regions simultaneously, then the information presentation capability is improved, but the device complexity increases
Solution Approach 1:
The display area is segmented into multiple independent display regions, each capable of showing different types of information. This segmentation allows the system to present diverse information simultaneously while keeping each region's control logic simple and manageable.
Solution Approach 2:
The control device pre-defines multiple display regions and their purposes before operation. This preliminary configuration simplifies real-time control decisions, as the system only needs to determine which pre-defined region to activate based on current conditions, rather than dynamically creating complex display arrangements.
3Object-affected harmful factors
If the display device transitions regions to non-display state based on vehicle direction, then visual distractions are reduced and safety is improved, but the loss of information increases
Solution Approach 1:
The system performs preliminary actions by preserving information in the background display region before transitioning to non-display state. This ensures that information is not lost but rather relocated to a non-intrusive state, maintaining availability while reducing distractions.
Solution Approach 2:
The background display region acts as an intermediary state between active display and complete non-display. Information can be temporarily held in the background region, serving as a buffer that prevents information loss while eliminating the distracting effect of foreground display during vehicle movement.

AI summary
A control device controls a display device capable of displaying visual information for a passenger of a moving body, in two or more display regions. The control device causes adjacent target regions of the display regions to change from a display state in which the information is displayed to a display restricted state in which display is restricted, according to a predetermined order, when a predetermined condition is satisfied. The control device determines the target regions and the order, based on a traveling direction of the moving body at the time when the condition is satisfied or a traveling direction of the moving body that is predicted after the time when the condition is satisfied.
