Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality (AR) devices lack global navigation satellite systems (GNSS) and fail to provide accurate positioning of virtual objects relative to the physical environment, leading to distorted renderings due to limited elevation data and processing power constraints, especially outdoors.
Innovation Solution
A software solution that transforms and simplifies data sets to maintain appropriate fidelity, allowing real-time display of georegistered information in AR/VR systems by converting local reference frames to a worldwide coordinate system, optimizing processing power and battery consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If high-resolution elevation data sets are used for accurate rendering, then rendering precision is improved, but processing power requirements and battery consumption increase
Solution Approach 1:
The patent divides the elevation data set into multiple resolutions or levels of detail. The system segments the data processing task by loading only the necessary portion of high-resolution data for the current field of view, while using lower-resolution data for areas outside the immediate view. This segmentation allows accurate rendering where needed while reducing overall processing requirements and battery consumption.
Solution Approach 2:
The patent implements local quality by applying high-resolution elevation data only to the specific region currently being displayed in the augmented reality view, while using lower-resolution data for other regions. This ensures rendering precision is maintained locally in the user's field of view without the need to process and store entire high-resolution data sets globally, thereby reducing battery consumption.
2Reliability
If complete elevation data sets are stored locally, then data availability is improved, but device storage requirements increase
Solution Approach 1:
The patent segments the elevation data into multiple resolution levels and stores them in a hierarchical structure. The system maintains high-resolution data for critical areas and lower-resolution data for broader regions, allowing complete data availability for the displayed area without requiring storage of entire high-resolution global data sets on the device.
Solution Approach 2:
The patent introduces an intermediary processing layer that retrieves elevation data from external sources or generates approximations when complete local storage is not feasible. This intermediary mechanism ensures data availability for rendering without requiring the device to store complete high-resolution elevation data sets locally, thus reducing storage requirements while maintaining reliability.
3Adaptability or versatility
If multiple world scaling options are provided, then user adaptability is improved, but processing power requirements increase
Solution Approach 1:
The patent implements dynamic scaling where the world scale is adjusted in real-time based on user interaction and context. Rather than providing all scaling options simultaneously requiring full processing for each, the system dynamically switches between predefined scale levels, reducing processing power requirements while maintaining user adaptability through on-the-fly adjustments.
Solution Approach 2:
The patent applies partial action by implementing a limited set of representative world scaling options that cover the most common use cases. Rather than providing exhaustive scaling possibilities, the system offers a curated subset of scales that satisfies user adaptability needs while significantly reducing the processing power required compared to supporting all possible scaling variations.
