Manager Terminal XR Concentration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual reality technologies face challenges in determining and managing user concentration when a user is wearing an extended reality (XR) device, making it inconvenient to use effectively, especially in applications like medical treatments where content engagement is crucial.
Innovation Solution
A method and system that utilize a manager terminal to transmit care content playback commands, receive gaze coordinate data, and output tracking marks to determine user concentration by calculating a difference value between current and predefined coordinates, adjusting playback speed to synchronize content across multiple XR devices, and managing latency information to ensure synchronized playback across all devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional virtual reality technology is used to output contents in virtual space, then the format of contents is changed, but it is difficult to determine and manage whether a user is properly watching contents
Solution Approach 1:
The patent introduces a manager terminal as an intermediary device that receives gaze coordinate data from the XR device and calculates user concentration. This mediator enables precise measurement of user concentration without complicating the XR device itself, resolving the contradiction between maintaining simple XR device operation and achieving accurate concentration measurement
Solution Approach 2:
The system implements feedback by continuously monitoring gaze coordinates, calculating concentration values, and using this information to control content playback. The manager terminal receives real-time gaze data, computes concentration based on tracking mark movements, and adjusts playback accordingly, enabling precise measurement while maintaining system adaptability
2Measurement precision
If gaze coordinate data is collected and tracking marks are displayed to determine user concentration, then user concentration can be determined, but the system complexity increases
Solution Approach 1:
The patent extracts the concentration calculation function from the XR device and places it in the manager terminal. The XR device simply collects gaze coordinates and transmits them, while the manager terminal handles the complex tasks of tracking mark generation, concentration calculation, and playback control. This extraction reduces XR device complexity while maintaining measurement precision
Solution Approach 2:
The manager terminal serves as an intermediary that handles all complex processing tasks. It receives simple gaze coordinate data from the XR device, performs sophisticated concentration calculations by analyzing tracking mark movements, and generates playback control signals. This intermediary approach concentrates system complexity in a dedicated control device rather than distributing it across multiple components
3Stability of the object's composition
If content playback speed is adjusted to synchronize multiple XR devices, then synchronized playback is achieved, but latency management becomes more complex
Solution Approach 1:
The system uses feedback by continuously monitoring playback status and latency information from multiple XR devices. The manager terminal receives real-time data about device states, calculates required playback speed adjustments to maintain synchronization, and sends control signals accordingly. This feedback loop achieves stable synchronized playback while centralizing latency management in the manager terminal
Solution Approach 2:
The patent implements dynamic playback speed adjustment where the manager terminal modifies content playback speed for individual XR devices based on their specific latency conditions. Rather than using a fixed playback rate for all devices, the system dynamically adapts each device's playback speed to compensate for latency variations, achieving synchronization while managing complexity through centralized dynamic control
