Vehicle Display Positioning via Visual-Line Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information display systems for vehicles do not account for the varying environmental conditions and the future direction a driver will view, leading to potential difficulties in recognizing important information.
Innovation Solution
An information display device that includes a prediction unit to forecast the driver's visual-line movement destination based on the vehicle's route and a display controller that adjusts the display position accordingly, ensuring information is easily visible by overlapping it with the landscape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display position is fixed based on current visual line direction, then the driver can recognize information rapidly at the current moment, but the information may not be visible when the driver's visual line moves to a different direction
Solution Approach 1:
The system performs preliminary action by predicting the driver's future visual line direction based on current visual line direction and vehicle traveling direction, and pre-adjusting the display position to where the information will be needed. This resolves the contradiction by preparing the display in advance rather than reacting after the visual line has already moved.
Solution Approach 2:
The display position is made dynamic by continuously adjusting it based on the combination of current visual line direction and predicted future direction. Instead of a fixed position, the system adapts the display location in real-time to match both current and anticipated driver viewing needs, resolving the contradiction between fixed accuracy and adaptive versatility.
2Adaptability or versatility
If multiple displays are used to cover different directions, then the driver can recognize information in various directions, but the device complexity increases
Solution Approach 1:
Instead of using multiple static displays to cover different directions, the system uses a single dynamic display that adjusts its position based on predicted visual line direction. This resolves the contradiction by achieving multi-directional coverage through dynamic repositioning rather than through multiple fixed displays.
Solution Approach 2:
A single display unit is made universal by enabling it to serve multiple directional purposes through dynamic position adjustment. The same display can present information for current visual line direction as well as predicted future directions, eliminating the need for dedicated displays for each direction and reducing overall system complexity.

AI summary
An information display device for displaying predetermined information while overlapping the predetermined information with a landscape having a prediction unit that obtains information on a route at a traveling front side and predicts a visual-line movement destination of a user on the basis of the obtained information, and a display controller that changes a display position for the predetermined information on the basis of a prediction result of the prediction unit.
