Vehicle Head-Up Display Layout for Concurrent Content Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems, such as head-up displays, often inefficiently manage multiple content images, leading to interruptions and poor user interaction when displaying driving-related and unrelated content simultaneously.
Innovation Solution
A vehicle display device with a display control unit that manages two content images on a single display by adjusting the display aspect of the first content image based on the second content information, prioritizing the display of prompting and result images, and controlling user input to prevent unintended actions during critical notifications, while maintaining visibility of essential driving information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple content images are displayed simultaneously on a head-up display, then information provision is enhanced, but display efficiency and user attention management deteriorate
Solution Approach 1:
The patent applies dynamics by making the display aspect of content images changeable based on situational conditions. The display control unit dynamically adjusts whether to display the first content image in normal aspect or in a compressed aspect ratio, depending on whether a second content image needs to be displayed simultaneously. This dynamic adjustment allows the system to optimize display efficiency while maintaining comprehensive information provision.
Solution Approach 2:
The patent changes the display parameter (aspect ratio) of the first content image based on the presence and importance of the second content image. When the second content image requires attention, the system compresses the first content image's aspect ratio to reduce its visual dominance, thereby managing user attention while preserving all information.
2Reliability
If a second content image is displayed to interrupt the first content image, then critical information can be conveyed, but user attention is fragmented and interaction becomes complex
Solution Approach 1:
The patent applies local quality by differentiating the display treatment of different content images based on their importance. The second content image (requiring user attention) is displayed in a visually prominent manner, while the first content image is compressed to a lesser visual weight. This local differentiation ensures critical information stands out without completely obscuring background information, maintaining ease of interaction.
3Productivity
If the display aspect of the first content image is changed when the second content image is displayed, then display efficiency is improved, but the first content image may become less visible
Solution Approach 1:
The patent applies partial action by compressing only the horizontal dimension of the first content image's aspect ratio rather than completely obscuring it or reducing it to minimal size. This partial compression maintains the first content image's visibility and information value while creating sufficient visual space for the second content image, achieving display efficiency without excessive loss of information.

AI summary
A vehicle display device includes a display control unit configured to display a first content image in a first display region on the basis of first information and display a second content image in a second display region on the basis of second information on a display unit on which an image is superimposed on an outside scenery so that the superimposed image is viewed. The display control unit changes a display aspect of the first content image on the basis of content of the second information when the first content image and the second content image are simultaneously displayed on the display unit.
