Automotive MR Service Platform for Context-Aware 3D Map Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mixed reality (MR) technologies for automotive applications lack an optimized platform for providing MR services that enhance vehicle driving experiences by integrating real-world information with virtual interfaces, failing to offer an efficient and user-centric interface for vehicle occupants.
Innovation Solution
A mixed reality automotive meta service (MR AMS) platform is developed, comprising an MR AMS server and client that utilize APIs for communication, a service aggregation manager for context requests, and a data integration manager for loading three-dimensional assets, along with a context manager for parsing and interpreting user requests, to provide optimized MR services tailored to the vehicle environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mixed reality technologies are used to provide various information and interfaces for vehicle driving, then user experience and information delivery are improved, but system complexity increases
Solution Approach 1:
The system is divided into distinct functional modules: MR content generation unit, MR content provision unit, and interface API. Each module handles specific tasks (generating MR content from sensor data, providing content to clients, managing communications) allowing the complex MR system to be managed through modular, independent components that can be developed and maintained separately
Solution Approach 2:
The patent introduces an interface API as an intermediary layer between the MR service platform and external systems. This mediator handles communication protocols, data formatting, and interface standardization, allowing the complex MR system to interact with diverse external devices through a unified, simplified interface
2Adaptability or versatility
If MR services are customized according to vehicle environment and user context, then service optimization is improved, but processing requirements and system complexity increase
Solution Approach 1:
The system pre-generates MR content based on anticipated vehicle contexts and user scenarios. The MR content generation unit creates virtual objects, augmented reality overlays, and interactive interfaces in advance for common driving situations, allowing the system to quickly deploy optimized services without real-time complex processing
Solution Approach 2:
The patent implements context-aware service delivery where different MR content and interfaces are provided based on specific vehicle conditions, user roles, and environmental factors. The system adjusts MR content properties (such as information density, visual prominence, interaction modes) locally according to the specific context rather than applying uniform processing to all scenarios
3Loss of information
If comprehensive context management is implemented for personalized MR services, then user-centric interface quality is improved, but data processing complexity increases
Solution Approach 1:
The context management system uses a hierarchical structure where general vehicle context data nests specific user context data, which in turn nests detailed interaction context. This nested organization allows the system to efficiently query and process only the relevant context layers needed for each MR service, avoiding the need to process all context data simultaneously
