XR Supervisory Device Spatial Multi-Streaming Replica
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Supervisors face challenges in assisting XR device users as they cannot easily obtain a representation of the XR environment being perceived by a specific user among multiple users.
Innovation Solution
A supervisory device that receives a selection of an XR device location, retrieves a replica stream associated with that XR device, and generates it for display, allowing the supervisor to monitor and assist the XR device user in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a supervisor wants to monitor multiple XR device users simultaneously, then the ability to obtain representations of XR environments is improved, but the device complexity and system resource requirements worsen
Solution Approach 1:
The system divides the monitoring task by creating separate replica streams for each XR device user. Each replica stream is an independent representation of what a specific user sees in the XR environment, allowing the supervisory device to monitor multiple users simultaneously without overwhelming complexity by processing everything as a single unified stream.
Solution Approach 2:
The system creates replica streams that are copies of the actual XR environment as perceived by each user. These replica streams are transmitted to the supervisory device, enabling the supervisor to view and monitor what each user experiences without directly accessing or interfering with the original XR devices, thus reducing system complexity while maintaining monitoring capability.
2Speed
If replica streams from multiple XR devices are transmitted to the supervisory device, then the real-time monitoring capability is improved, but the bandwidth and data transmission requirements worsen
Solution Approach 1:
The system extracts only the essential visual information from each XR device and transmits it as a replica stream to the supervisory device. This extraction approach allows real-time monitoring by sending only the necessary data (what the user sees) rather than transmitting all possible information, thereby reducing bandwidth consumption while maintaining real-time monitoring speed.
3Ease of operation
If the supervisory device displays multiple replica streams simultaneously, then the supervisor's ability to assist users is improved, but the ease of operation and interface complexity worsen
Solution Approach 1:
The system maps the spatial positions of XR devices in the physical environment onto a two-dimensional map display on the supervisory device. Each replica stream is associated with a corresponding location on the map, allowing the supervisor to navigate and select which user to monitor by interacting with the map interface rather than managing multiple complex video feeds directly. This dimensional mapping simplifies the interface while maintaining the ability to assist multiple users.

AI summary
The disclosure relates to method and system for supervising a plurality of users of XR devices. A problem arises in that a supervisor hoping to assist a user in operating in an XR environment cannot easily obtain a representation of the XR environment which a particular user amongst the plurality of users is currently perceiving. The disclosure addresses this problem by having each XR device and a supervisory device independently determine the position of an XR device. Each XR device provides replica stream data in association with its position, and the user of the supervisory device selects an XR device by selecting its position. By tallying the position in the supervisor's selection of an XR device with the position associated with each replica stream, the replica stream of the XR device selected by the supervisor can be provided to the supervisory device.
