Vehicle Display Marker Layout for Perceived Position Offset Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies in vehicles, such as head-up displays (HUDs), often cause markers to be displayed in positions offset relative to preceding vehicles due to variations in object detection precision, leading to noticeable positional offsets that affect user perception.
Innovation Solution
The display control device and method employ markers composed of multiple partial images arranged in a vehicle width direction with sides not parallel to the vehicle vertical direction, and adjust display modes based on confidence values and distances to minimize perceptible offsets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a marker is displayed in a position corresponding to an object such as a preceding vehicle, then the marker provides positioning information to the user, but the position of the marker may be offset relative to the object due to detection precision fluctuations
Solution Approach 1:
The marker is divided into multiple partial images arranged in the vehicle width direction. Each partial image corresponds to a detection point, and the segmented structure allows the system to handle position uncertainties by distributing the marker across multiple locations rather than concentrating it at a single potentially inaccurate position.
Solution Approach 2:
The marker uses a polygonal shape with short sides not parallel to the vehicle vertical direction. This asymmetric design creates multiple edges at different vehicle width positions that serve as reference points, making it difficult for users to precisely judge the marker's center position and thereby reducing the perceived impact of position offsets.
2Ease of operation
If the marker has a simple shape, then the marker is easy to recognize, but the offset in position may be clearly perceived by the user
Solution Approach 1:
The marker employs a polygonal shape with short sides not parallel to the vehicle vertical direction, creating an asymmetric design. This asymmetry generates multiple edges at different vehicle width positions that serve as reference points, making it difficult for users to precisely judge the marker's center position and thereby reducing the perceived impact of position offsets.
Solution Approach 2:
The marker is divided into multiple partial images arranged in the vehicle width direction. This segmented structure maintains simplicity while creating multiple reference edges that distribute the position uncertainty, allowing the marker to remain easily recognizable while reducing perceived position offset.
3Measurement precision
If the marker is positioned to be superimposed on the object, then the marker provides accurate positioning feedback, but detection precision fluctuations cause the marker to be displayed in an offset position
Solution Approach 1:
The marker is divided into multiple partial images arranged in the vehicle width direction, with each partial image corresponding to a detection point. This segmentation allows the system to maintain positioning feedback while distributing the impact of detection precision fluctuations across multiple locations, thereby improving reliability.
Solution Approach 2:
The system changes the spatial parameters of the marker by dividing it into multiple partial images at different vehicle width positions. This parameter change transforms a single-point positioning problem into a distributed positioning system that is more robust to detection precision fluctuations.

AI summary
A display control device includes a display control unit that causes a marker to be displayed in a display area of a display device in a position corresponding to an object included in a foreground of a vehicle visible through the display area of the display device or in an image resembling the foreground of the vehicle displayed in the display area of the display device, and the marker comprising a plurality of partial images lined up next to and spaced apart from each other in a vehicle width direction and having sides along a lengthwise direction of the partial images that are not parallel to a vehicle vertical direction.
