AR-HUD Marker Deformation for Off-Screen Vehicle Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality head-up displays (AR-HUDs) fail to intuitively indicate when a preceding vehicle moves out of the display area, leading to ambiguity in the design change of marker images.
Innovation Solution
A display control device that projects a marker image within a screen display frame, adjusting its shape and size based on the vehicle's position, including deformation and animation to indicate when the vehicle is outside the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the marker image is continuously displayed in a screen display frame when the preceding vehicle moves outside the display area, then the information remains visible, but it becomes difficult for the driver to determine whether the design change is due to the vehicle position or another factor
Solution Approach 1:
The marker image changes its design (color, shape, or pattern) based on the position of the preceding vehicle. When the vehicle is within the display area, one design is shown; when outside, a different design is displayed. This visual transformation allows the driver to intuitively recognize the vehicle's position status while maintaining information visibility.
Solution Approach 2:
The marker image dynamically adapts its appearance according to the real-time position of the preceding vehicle. The system continuously monitors vehicle position and adjusts the marker design accordingly, creating a dynamic visual feedback mechanism that improves driver awareness without sacrificing information visibility.
2Illumination intensity
If the marker image is displayed at maximum size when the vehicle is in the screen display frame, then visibility is improved, but the display area is limited
Solution Approach 1:
The system changes the display parameters of the marker image based on the position of the preceding vehicle. When the vehicle is within the display area, the marker is displayed at maximum size for optimal visibility. When the vehicle moves outside, the marker design changes to indicate the position status, allowing the system to maintain visibility while adapting to limited display area constraints.

AI summary
A display ECU is configured to detect, from an image acquired by a camera, a vehicle to be followed that precedes a host vehicle, project a marker image, in the screen display frame, with any one of a display near the vehicle to be followed and a display on the vehicle to be followed in a superimposed manner, and control the AR-HUD such that the marker image exhibits, when the entire vehicle to be followed is in the screen display frame, a first shape in which the marker image is displayed at maximum size, and the marker image exhibits, when the vehicle to be followed deviates from the screen display frame, a second shape in which the marker image deforms in a state of being in contact with the screen display frame according to a position of the vehicle to be followed present outside the screen display frame.
