AR Shared Screen Space With Avatars for Low-Power Collaboration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
AR wearable devices have limited physical user interface items, battery power, and processing capability, making it difficult for users to collaborate effectively on projects, especially when sharing screens and providing feedback.
Innovation Solution
A 'Host' AR wearable device provides a shared screen with size, location, and avatar information, while 'Guest' devices display the shared screen and avatars, allowing users to share augmentations and see each other's relative positions and movements, enhancing collaboration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If AR wearable devices provide additional functions for user collaboration, then the collaboration capability is improved, but the battery power is consumed faster
Solution Approach 1:
The system divides collaboration functions into host device responsibilities (screen sharing, avatar management, spatial mapping) and guest device responsibilities (receiving and displaying shared content). This segmentation allows each device to perform only necessary computations, reducing overall battery consumption while maintaining full collaboration capability across the group.
Solution Approach 2:
The patent introduces a shared virtual screen space as an intermediary that mediates collaboration between multiple users. Instead of each device processing all collaboration data, the intermediary virtual space handles the coordination, allowing devices to consume less power while maintaining effective collaboration through the shared virtual environment.
2Ease of operation
If AR wearable devices provide additional interface controls for collaboration, then the user interaction capability is improved, but the device complexity increases
Solution Approach 1:
The shared virtual screen space acts as an intermediary that provides the collaborative interface, eliminating the need for complex controls on each wearable device. Users interact with the virtual screen and avatars using simple gestures or voice commands, while the intermediary system handles the complex coordination of multiple users, screen sharing, and spatial management.
Solution Approach 2:
The system automatically manages complex collaboration tasks such as avatar positioning, screen coordinate mapping, and spatial relationships without requiring users to configure these parameters manually. The AR devices self-configure their role (host or guest) and automatically establish the shared virtual space, reducing the complexity of user interaction.
3Speed
If AR wearable devices process and display shared screen content in real-time, then the collaboration responsiveness is improved, but the processing capability is exceeded
Solution Approach 1:
The patent extracts the heavy processing requirements for screen sharing and spatial mapping to the host device, which has greater processing capability. Guest devices only need to receive and display pre-processed visual content and avatar positions, significantly reducing their processing burden while maintaining real-time collaboration responsiveness through efficient data transmission.

AI summary
Systems, methods, and computer readable media for an augmented reality (AR) shared screen space. Examples relate to a host augmented realty (AR) device sharing a screen and a relative location of the AR device to the screen with guest AR devices where the guest AR devices share a relative location of the guest AR devices to a copy of the screen displayed on the display of the guest AR devices and where the users of the AR devices may see each other's location with the use of avatars around the shared screen and add augmentations to the shared screen. The yaw, roll, and pitch of the head of the avatars tracks the movement of the head of the user of the AR wearable device.
