AR Object Sharing Through Local Anchors for Co-Located Collaboration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable electronic devices, such as electronic eyewear, lack the capability to enable users to share augmented reality objects with co-located users in a seamless and interactive manner, limiting social connectivity and collaboration.
Innovation Solution
The system enables users of electronic eyewear devices to share augmented reality objects by identifying co-located users within a local network, establishing collaboration sessions, and allowing co-located users to modify and annotate shared objects using AR display tools, with the system incorporating visible light cameras, image processors, and collaboration software to facilitate object sharing and modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users share AR objects with co-located users through electronic eyewear devices, then social connectivity and collaboration are enhanced, but device complexity and network infrastructure requirements increase
Solution Approach 1:
The system segments the AR object sharing functionality into distinct modules: object detection module using visible light cameras, image processing module for rendering AR objects, collaboration session management module for coordinating between users, and annotation tools module. This segmentation allows each component to be optimized independently while working together to enable social connectivity without overwhelming system complexity.
Solution Approach 2:
The electronic eyewear device is designed with multi-functionality, serving as both a consumer electronics device for AR content consumption and a collaboration tool for social interaction. The same hardware infrastructure (cameras, processors, displays) supports both individual AR experiences and shared collaborative sessions, reducing the need for separate specialized equipment.
2Ease of operation
If real-time collaboration on AR objects is enabled among co-located users, then interactive experience is improved, but processing requirements and energy consumption increase
Solution Approach 1:
The system implements periodic action by updating AR objects and annotations at optimized intervals rather than continuously. Collaboration sessions synchronize state changes at discrete moments when modifications occur, and visibility ranges are periodically recalculated based on user movement. This approach maintains real-time interactive experience while reducing continuous processing demands and energy consumption.
Solution Approach 2:
The system applies local quality by rendering AR objects and annotations only within each user's specific field of view and visibility range. The image processor selectively renders content based on detected user orientation and position, avoiding unnecessary processing of areas outside the current view. This localized rendering approach reduces overall processing requirements while preserving the immersive interactive experience.
3Measurement precision
If AR objects are shared with co-located users using visible light cameras and image processors, then object recognition accuracy is improved, but device complexity increases
Solution Approach 1:
The system introduces an intermediary approach by using visible light cameras as mediators between the physical world and digital AR objects. These cameras capture real-world scenes and pass them to image processors that detect and recognize objects, establishing accurate spatial relationships. This intermediary optical detection mechanism achieves high object recognition accuracy without requiring direct complex sensor integration into the AR display system.

AI summary
Users of electronic eyewear devices can interact with each other by sharing 3D objects (e.g., 2D or 3D augmented reality (AR) objects or scanned 2D or 3D images of real-world objects) with each other via local objects (real or virtual) in each user's environment established as personalized anchor points for social connection. When a user receives an object from another user, the user has the option to generate a connected session with other users that are co-located (physically or virtually at the same location) with the user. The co-located group of users in this new connected session may view the received object either on their personal electronic devices (e.g., smartphones) or on their electronic eyewear devices and can modify and annotate the shared object using collaboration software and AR display tools that enable modification and manipulation of the shared object.
