Global AR Perspective via Stationary Sensor Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current AR and MR technologies are limited to local perspectives and are not capable of providing a global view of the user's environment, restricting their application to single rooms and a single user, and lack the ability to seamlessly integrate multiple users and physical spaces.
Innovation Solution
A system that uses stationary sensors to measure user locations and store map data of the physical environment, allowing a server to provide a global perspective to a headset, enabling rendering of virtual content across multiple rooms and outdoor spaces, and allowing multiple users to interact through avatars, with features like virtual interconnects for reorienting spaces and teleportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If stationary sensors and map data are used to provide global perspective, then the coverage area and multi-user capability are improved, but the device complexity and infrastructure requirements worsen
Solution Approach 1:
The patent introduces stationary sensors and a server as intermediary components between users and the virtual content system. The sensors capture real-world location data, the server processes this data along with map information, and returns calculated virtual content parameters to headsets. This intermediary infrastructure enables global perspective and multi-user support while keeping individual headset complexity manageable.
2Adaptability or versatility
If local perspective AR/MR is used, then the device complexity is reduced, but the adaptability to different physical spaces and multi-user interaction worsens
Solution Approach 1:
The patent transitions from local, headset-centered coordinate systems to a global, map-based coordinate system that encompasses multiple physical spaces. By introducing a higher-level dimensional framework (the map data representing entire buildings or campuses), the system can adapt virtual content across diverse environments and support multiple users simultaneously, while the complexity is managed through server-side processing rather than in the headsets.
Data Source
AI summary
A technique for rendering virtual content to a user stores map data of features in a physical environment of the user and measures the location of the user with stationary sensors placed at respective locations within the environment. A server provides the location of the user and portions of the map data to a headset worn by the user. The headset is thus enabled to render virtual content at apparent locations that are based on the measured location of the user and the features described by the map data.
