Head-Up Display Layout for Sequential Route Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-up display devices struggle to intuitively present multiple pieces of driving-related information along a vehicle's travel route due to the limited vertical length of the image forming plane, making it difficult for drivers to recognize sequential information without obstructing their line of vision.
Innovation Solution
A head-up display device that projects driving-related information onto an image forming plane with a horizontal length greater than its vertical length, using line segment objects to represent the driving lane and positioning information objects diagonally along these lines to create a sense of perspective, with the first information object displayed more prominently to direct the driver's attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the image forming plane has a short length in the up-down direction to avoid obstructing the driver's line of vision, then the driver's view remains unobstructed, but it becomes difficult to arrange multiple information objects sequentially along the travel route
Solution Approach 1:
The patent transitions from vertical arrangement to diagonal arrangement along perspective lines. Information objects are positioned along diagonal lines extending from the center toward the periphery, creating a perspective-based spatial organization that utilizes the horizontal dimension more effectively while maintaining compact vertical footprint.
Solution Approach 2:
The patent employs asymmetric positioning of information objects relative to the center line. Objects are deliberately placed at different diagonal positions and distances from the center, creating an asymmetric layout that guides the driver's attention along the perspective lines while fitting within the constrained vertical space.
2Loss of information
If multiple information objects are arranged vertically to show sequential travel route information, then all information can be displayed, but the image forming plane becomes too tall and obstructs the driver's view
Solution Approach 1:
The patent redistributes information objects from a vertical stack to diagonal arrangements along perspective lines. This dimensional transformation allows multiple objects to be displayed simultaneously within a shorter vertical envelope by utilizing the horizontal and diagonal spatial dimensions.
Solution Approach 2:
The patent segments the information display into multiple diagonal zones or regions along the perspective lines. Each zone can contain specific information objects, and these segmented zones are arranged diagonally rather than vertically, enabling better spatial utilization and reduced vertical obstruction.
3Object-affected harmful factors
If information objects are positioned to fit within a compact vertical space, then the driver's view is maintained, but the intuitive recognition of sequential information along the travel route is compromised
Solution Approach 1:
The patent introduces diagonal perspective lines as a new spatial dimension for organizing information. By positioning objects along these diagonal lines rather than vertically, the system creates an intuitive visual pathway that guides the driver's eye through the sequence of information while maintaining compact vertical dimensions.
Solution Approach 2:
The patent applies different positional qualities to different information objects based on their importance and sequence. Objects closer to the center or at specific diagonal positions may be emphasized, creating local variations in visual weight and attention guidance that enhance intuitive recognition without requiring vertical expansion.

AI summary
A head-up display device that is configured to allow a driver to intuitively recognize a plurality of objects sequentially along a travel route of a vehicle while projecting a video onto an image forming plane that has a length in the vertical direction shorter than a length in the horizontal direction. An optical processor of the head-up display device obtains from a controller a first image signal based on the nearest road sign information and a second image signal based on the following road sign information along the travel route. The optical processor causes line segment objects as well as information objects generated from the first image signal and the second image signal, respectively, to be displayed on an image forming plane.
