Head-Up Display Route Guidance Visibility Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle head-up display systems struggle to provide an easy-to-understand visual representation of route guidance, as content is often overlapped between visible and invisible areas within the driver's field of view, making it difficult for occupants to distinguish and recognize the route accurately.
Innovation Solution
A display control device and program that estimate the visible and invisible areas within the head-up display's field of view and differentiate the display mode of overlapping route content, allowing the driver to visually distinguish between visible and invisible parts of the route guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If route content is displayed in a superimposed manner on the road surface, then the driver can see the route guidance within the field of view, but the content overlaps between visible and invisible areas making it difficult to distinguish
Solution Approach 1:
The route content is segmented into visible and invisible parts based on the estimated visible area. The display control unit distinguishes between these parts and applies different display modes (e.g., different brightness levels, transparency, or visual indicators) to help the driver understand which portions of the route are currently visible versus those that extend into invisible areas.
Solution Approach 2:
Different display qualities are applied to different portions of the route content. The visible part is displayed with one set of visual characteristics while the invisible part is displayed with different characteristics, allowing the driver to locally distinguish between route portions based on their visibility status.
2Loss of information
If the head-up display shows the entire route content, then complete route information is provided, but the overlapping content in invisible areas causes confusion for the occupant
Solution Approach 1:
The complete route content is segmented into visible and invisible portions. Both portions are displayed to maintain information completeness, but they are visually differentiated through different display modes so that the driver can clearly recognize which parts are currently visible and which are in invisible areas.
Solution Approach 2:
Different visual characteristics (such as brightness, color intensity, or transparency) are applied to visible and invisible route content portions, enabling the driver to distinguish between them while still receiving complete route information.

AI summary
A display control device controls a superimposed display of a content by a head-up display for a vehicle. The display control device estimates a visible area of a road surface in a foreground included in an angle of view of the head-up display, and an invisible area of the road surface in the foreground included in the angle of view; distinguishes, in a route content, a visible part superimposed in the visible area, an invisible part superimposed in the invisible area, and an overlapping portion between the visible part and the invisible part; and causes the overlapping portion to be displayed in a display mode different from display modes of a visible non-overlapping portion of the visible part out of the overlapping portion and an invisible non-overlapping portion of the invisible part out of the overlapping portion.
