Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multiplayer augmented reality (AR) experiences using smart glasses face inefficiencies such as cumbersome device discovery and connection processes, misaligned virtual content across multiple users, and resource-intensive centralized processing, leading to frustrating user experiences and resource waste.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized processing is used for multiplayer AR sessions, then coordination and synchronization are improved, but resource consumption and system complexity increase
Solution Approach 1:
The patent divides the centralized processing architecture into distributed peer-to-peer processing among wearable devices. Each device independently processes and renders AR content locally, eliminating the need for a central server to handle all computational tasks. This segmentation reduces resource consumption at any single point while maintaining coordination through direct device-to-device communication.
Solution Approach 2:
The patent extracts the coordination function from centralized server processing and implements it through decentralized protocols between devices. The synchronization logic is removed from the central system and distributed to individual devices, allowing each device to autonomously manage its own AR session while coordinating with others through lightweight communication protocols.
2Reliability
If manual device pairing and session setup procedures are used, then connection reliability is improved, but user interaction complexity and setup time increase
Solution Approach 1:
The patent implements preliminary device discovery and automatic pairing protocols that prepare devices for connection before user interaction is needed. Devices continuously broadcast and listen for session identifiers in the background, pre-establishing communication channels so that when users want to join a session, the pairing is already facilitated or complete, eliminating manual configuration steps.
Solution Approach 2:
The patent enables devices to automatically discover, pair, and join AR sessions without human intervention. The system self-manages connection establishment, session synchronization, and device coordination through automated protocols, reducing user interaction to simple intent-based commands while the technical complexity is handled autonomously by the devices themselves.
3Adaptability or versatility
If virtual content is displayed across multiple wearable devices, then multiplayer AR experience is improved, but alignment precision and synchronization difficulty increase
Solution Approach 1:
The patent implements real-time feedback loops where each wearable device continuously monitors the position, orientation, and timing of virtual content relative to other devices. This feedback is used to dynamically adjust rendering parameters, synchronization timing, and spatial alignment to maintain precise coordination across the multiplayer AR environment despite device movement and environmental variations.
Solution Approach 2:
The patent employs dynamic synchronization protocols that adapt to changing device positions, orientations, and network conditions in real-time. Rather than using static alignment parameters, the system continuously updates coordination data between devices, allowing virtual content to maintain precise spatial relationships even as users move and interact with the shared AR environment.

AI summary
Examples relate to systems and methods for providing multiplayer experiences on a head-wearable apparatus, such as AR glasses. The system receives, by a first head-wearable apparatus, a short-range wireless signal from a second head-wearable apparatus, the short-range wireless signal including data that identifies a first digital effects session that is currently active on the second head-wearable apparatus. The system obtains, by the first head-wearable apparatus, information corresponding to the first digital effects session based on the data. The system, in response to obtaining the information corresponding to the first digital effects session, presents an indicator in a user interface of the first head-wearable apparatus, the indicator informing a user of the first head-wearable apparatus that one or more digital effects sessions are currently active on one or more head-wearable apparatuses within a threshold distance of the first head-wearable apparatus.
