AR Headset Content Anchoring via Global Coordinate Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for presenting augmented reality content face challenges in allowing seamless interaction between users in physical space, as they often lack coordination and fail to present the same content effectively across different augmented reality devices, which limits collaborative experiences and presentation consistency.
Innovation Solution
A system utilizing a head-mounted display with sensors and processors to designate and anchor content display locations within a physical environment, allowing for coordinated presentation of interactive mixed reality content across multiple devices, including the use of a transparent display, optical sensors, and user input devices to manage content positioning and interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If augmented reality content is presented to multiple users using different augmented reality devices, then each user can interact with the physical environment and maintain their own field of view, but the content cannot be presented in correspondence with the same physical space or with the same orientation
Solution Approach 1:
The patent introduces a coordinate system as an intermediary framework that mediates between multiple augmented reality devices and the physical space. Each device maps its local coordinate system to a shared global coordinate system, enabling content to be positioned consistently across different devices while preserving each user's ability to interact with the physical environment independently
Solution Approach 2:
The patent creates a universal coordinate system that serves all augmented reality devices simultaneously. This universal framework allows the same content to be presented across multiple devices with consistent positioning and orientation, while each device maintains its own operational independence and ability to adapt to the physical environment
2Manufacturing precision
If virtual reality content is presented to multiple users, then the content can be presented in a common frame of reference with users placed in the same location, but interaction between users in their physical space is severely limited
Solution Approach 1:
The patent applies different quality characteristics to different aspects of the augmented reality experience. The coordinate system mapping provides precise, consistent positioning for content across devices, while the overlay nature of augmented reality preserves local physical interactions. Each user maintains accurate content positioning while simultaneously retaining full ability to interact with their physical environment without the constraints of complete immersion
3Ease of operation
If augmented reality devices are used by users in the same room, then users can interact with the physical environment with relative ease, but the devices cannot coordinate to present content according to instructions from a presenter
Solution Approach 1:
The patent implements feedback mechanisms where each augmented reality device reports its position, orientation, and field of view back to a coordinating system. This feedback loop enables the system to calculate appropriate content positioning for each device based on its current state, allowing coordinated content presentation while maintaining ease of physical interaction. The coordinate system mapping serves as the feedback channel that connects individual device states to centralized coordination
