Vehicle HUD Customizing Windshield Projection Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-up display (HUD) systems for vehicles cannot optimize information display and range according to individual driver preferences, habits, or driving styles, leading to suboptimal user experience.
Innovation Solution
A projection type display device equipped with a light source, light modulation element, projection unit, operation unit, designation information acquisition unit, and image information generation unit, allowing drivers to customize the content, display size, and layout of information projected onto a vehicle's windshield or combiner based on their preferences through voice commands or touch interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If display content is fixed for all drivers, then the system is simple to operate, but it cannot provide personalized information according to driver hobbies and preferences
Solution Approach 1:
The system allows drivers to pre-configure their preferred display settings through the operation unit before actual driving. Drivers can select desired information types, adjust display ranges, and customize content presentation in advance. These preliminary settings are stored and automatically applied, eliminating the need for complex real-time adjustments while maintaining high personalization.
2Quantity of substance
If the number of displayable content items is increased, then more information can be provided to the driver, but the display becomes more complex and harder to manage
Solution Approach 1:
The HUD system applies local quality by allowing different display regions to present different types and quantities of information based on driver preferences. The display control unit selectively activates specific content items in specific display areas, ensuring that each region serves its optimal function without overwhelming the entire display system with unnecessary complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables personalized information display according to driver desires, enhancing user experience by allowing customization of content, size, and layout, thereby improving the relevance and effectiveness of driving assistance information.
Implementation Method 1
a light modulation element that spatially modulates light emitted from the light source on the basis of image information
Implementation Method 2
a projection unit that projects image light that is spatially modulated by the light modulation element onto a projection surface of a vehicle
Data Source
AI summary
Provided is a projection type display device capable of performing display of information according to a driver's desire. An HUD includes light sources; a light modulation element that spatially modulates light emitted from the light sources on the basis of projection image data; a projection unit that projects image light that is spatially modulated by the light modulation element onto a projection surface that is a part of a windshield 1 mounted in an automobile; a designation information acquisition unit that acquires designation information for designating at least one of a maximum number of pieces of content included in the projection image data, display sizes of the pieces of content, or arrangement layouts of the pieces of content on the basis of information input through an operation unit; and an image information generation unit that generates the projection image data on the basis of the designation information acquired.
