Real-Time 3D Interface Rendering in Vehicle Infotainment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle infotainment systems rely on precalculated 2D representations, which limit the visualization of complex spatial relationships and offer little flexibility, as they require significant storage space and cannot effectively depict dynamic interactions within the vehicle.
Innovation Solution
Implementing real-time 3D rendering within the vehicle's computing device to generate animated 3D representations of user interfaces, allowing for dynamic changes based on user interactions and enhanced visualization of vehicle functions, reducing storage needs and increasing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 3D representations are precalculated outside the vehicle and stored, then storage space requirements increase, but flexibility and adaptability are reduced
Solution Approach 1:
The patent transitions from static precalculated 3D representations to dynamic real-time rendering. The rendering device generates 3D representations dynamically based on current vehicle state and user interaction, allowing the system to adapt to changing conditions without storing multiple variants. This resolves the contradiction by making the system flexible through real-time generation rather than through stored variants.
Solution Approach 2:
The vehicle's own computing resources are utilized to render 3D representations in real-time. Instead of relying on pre-stored content from external sources, the system serves itself by generating visualizations on-demand using its internal processing power, thereby eliminating the need for large storage spaces while maintaining high adaptability.
2Loss of information
If 3D representations are precalculated outside the vehicle, then visualization of complex spatial relationships improves, but system complexity and processing requirements outside the vehicle increase
Solution Approach 1:
The patent extracts the rendering function from external precalculation systems and relocates it to the vehicle's own computing device. This allows high-quality 3D visualization to be achieved while eliminating the complexity of external rendering systems. The visualization quality is maintained through real-time rendering capabilities within the vehicle.
Solution Approach 2:
The vehicle's computing device is designed to perform multiple functions including real-time 3D rendering of various user interfaces. Instead of requiring separate external systems for different visualization needs, a single multi-functional rendering system handles all 3D representation requirements, reducing overall system complexity while maintaining visualization quality.
3Device complexity
If 2D representations are used in the vehicle, then device complexity is reduced, but the ability to visualize spatial relationships and functions is limited
Solution Approach 1:
The patent transitions from 2D representations to 3D representations by adding a spatial dimension to the user interface visualizations. This dimensionality change enables much better visualization of spatial relationships and vehicle functions while the rendering is performed efficiently within the vehicle's computing resources, maintaining acceptable system complexity.
Data Source
AI summary
A method for generating a 3D representation of a user interface in a vehicle, in which a scene, in particular a moving scene, containing at least one 3D object is rendered by a computing device inside the vehicle in order to determine the 3D representation.
