Gaze-Based AR Location via SLAM Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality systems face challenges in providing a visually intuitive sense of location for objects, locations, or people, especially in environments with visual obstacles or dynamic changes, and in coordinating multiple users' mapping and relative positioning within augmented reality systems.
Innovation Solution
The use of SLAM gear sets equipped with transceivers, cameras or sensors, local processing units, and augmented reality displays that detect user gaze and perspective, create and overlay three-dimensional maps, and correlate relative positions between users, enabling real-time visual overlays on transparent or non-transparent displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If augmented reality overlays are used to provide location information, then visual intuition of object and person positioning is improved, but the system complexity increases due to integration with SLAM technology
Solution Approach 1:
The patent combines multiple technologies (augmented reality overlays, SLAM gear sets, transceivers, cameras, and processing units) into an integrated system. The SLAM technology creates path maps and determines relative locations, while augmented reality overlays visually present this information to users, merging navigation and visualization functions into a unified system that reduces information loss.
2Adaptability or versatility
If multiple SLAM gear sets are used to create path maps and determine relative locations, then coordination between multiple users is improved, but the device complexity and processing requirements increase
Solution Approach 1:
The system divides the overall navigation task into segments handled by individual SLAM gear sets. Each gear set independently creates its own path map and determines its relative location, then communicates this information through transceivers. This segmentation allows multiple users to operate independently while maintaining system-wide coordination, managing processing complexity through distributed computation.
Solution Approach 2:
Each SLAM gear set is designed as a universal, multi-functional unit that can perform path mapping, relative location determination, and communication with other gear sets. This universality allows any number of users to be coordinated using the same standardized equipment and protocols, enhancing multi-user adaptability without proportionally increasing individual device complexity.
3Ease of operation
If visual overlays are displayed in the user's line of sight, then ease of operation and navigation intuition are improved, but the difficulty of detecting and measuring user gaze and perspective increases
Solution Approach 1:
The patent replaces direct mechanical or manual methods of determining user perspective with sensor-based detection systems. Cameras and sensors capture visual data about the user's line of sight and perspective, which is then processed to determine where the user is looking. This substitution enables accurate gaze detection without requiring complex mechanical tracking apparatus.
