Vehicle HUD Multi-Layer Display for Variable Virtual Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle user interfaces, particularly Head Up Displays (HUDs), utilize a single display layer with a fixed virtual distance, which is insufficient for efficiently providing complex traffic information, leading to driver fatigue and a weak sense of reality.
Innovation Solution
A user interface apparatus with multiple display layers, each having a different virtual distance, controlled by a processor to vary based on driving situation information, applying out-of-focus and fade-in/fade-out effects to enhance information recognition and reality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single display layer with fixed virtual distance is used, then the device complexity is reduced, but the information efficiency and sense of reality deteriorate
Solution Approach 1:
The display system is segmented into multiple display layers (first display layer, second display layer, etc.), each capable of displaying different types of information at different virtual distances. This segmentation allows complex traffic information to be organized across multiple layers, improving information efficiency without requiring a complete system redesign.
Solution Approach 2:
The patent introduces the dimension of virtual distance by implementing multiple display layers at different depths. This transforms the traditional single-plane display into a multi-depth spatial display system, enabling information to be presented with varying virtual distances to enhance the sense of reality and information recognition efficiency.
2Device complexity
If a single display layer with fixed virtual distance is used, then the device complexity is reduced, but the sense of reality deteriorates
Solution Approach 1:
By adding the virtual distance dimension through multiple display layers, the system creates a more realistic spatial representation of traffic information. Different layers can simulate objects at different distances from the driver, enhancing the sense of reality and reducing driver fatigue caused by flat, two-dimensional displays.
Solution Approach 2:
Different display layers are assigned different local qualities in terms of virtual distance and information type. Critical safety information can be displayed on layers with appropriate virtual distances that match their semantic meaning, creating a more realistic and reliable user interface.
3Loss of information
If multiple display layers with varying virtual distances are implemented, then the information efficiency and sense of reality are improved, but the device complexity increases
Solution Approach 1:
The display system is divided into multiple independent display layers, each capable of displaying specific types of information. This segmentation allows the system to present complex traffic information in an organized manner across different layers, improving information efficiency while maintaining manageable system architecture.
Solution Approach 2:
Each display layer is designed to be multi-functional, capable of displaying various types of traffic information (navigation, warnings, speed, etc.) at different virtual distances. This universality reduces the need for separate specialized displays for each information type, balancing the increased complexity with versatile functionality.
4Reliability
If multiple display layers with varying virtual distances are implemented, then the sense of reality is enhanced, but the device complexity increases
Solution Approach 1:
The implementation of multiple display layers at different virtual distances creates a three-dimensional spatial representation of traffic information, significantly enhancing the sense of reality. This dimensional approach allows critical information to be positioned at appropriate virtual depths, making the interface more intuitive and reducing driver cognitive load despite the increased system complexity.
