Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extended reality systems face challenges in synchronizing data across multiple output devices, leading to increased complexity and additional delays, particularly when the number of devices increases, resulting in interruptions in the user's experience.
Innovation Solution
An extended reality system that uses a computer to transmit output data including device identifiers and time limits to specific extended reality output devices, ensuring that only relevant data is reproduced within the specified time frame, using a NFXM format for data transmission and encryption to maintain seamless user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional synchronization methods are used to coordinate multiple output devices, then data can be transmitted to all devices, but the system complexity increases and additional delays occur
Solution Approach 1:
The patent segments the data transmission process by including device identifiers in the output data packets, allowing each extended reality output device to independently identify and process only its designated data portions. This segmentation eliminates the need for complex centralized coordination between multiple devices, reducing system complexity while maintaining reliable synchronization.
2Reliability
If traditional synchronization methods are used to coordinate multiple output devices, then data can be transmitted to all devices, but additional delays occur in data reproduction
Solution Approach 1:
The patent implements preliminary action by including time limit information in the output data packets before transmission. Each extended reality output device uses this pre-provided time limit to immediately reproduce its designated data without waiting for coordination signals from other devices, thereby eliminating additional delays while ensuring synchronized reproduction across all devices.
3Reliability
If all output devices receive and process all reproduction data, then complete data coverage is achieved, but data processing efficiency decreases
Solution Approach 1:
The patent applies local quality by assigning specific device identifiers to different extended reality output devices and including corresponding identifiers in output data packets. Each device processes only the data packets containing its designated identifier, ensuring complete data coverage across all devices while significantly improving individual device processing efficiency by eliminating unnecessary data handling.

AI summary
According to an embodiment, there is provided an extended reality (XR) system based on multimodal interfaces including a computer configured to broadcast output data including at least one device identifier (ID), at least one time limit, and at least one reproduction data to at least one extended reality output device, and at least one extended reality output device configured to receive the output data and reproduces only reproduction data corresponding to itself within the time limit based on the at least one device identifier (ID). According to this, a user can experience reproduction of five senses with a sense of reality without interruption.
