Solution Overview

Problem

Existing technologies struggle to accurately predict and synchronize the implementation of virtual smoke in virtual reality (VR) environments with the user's real-time smoking actions, leading to a disjointed experience.

Innovation Solution

A method of controlling an electronic device to predict a virtual smoke implementation timepoint by monitoring the distance between the device and the user, using sensors to detect changes in distance, respiration volumes, and operating conditions, and transmitting a control signal to a VR device to implement virtual smoke at the predicted timepoint.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If virtual smoke is displayed in real-time without prediction, then the response speed is fast, but the synchronization with user's actual exhalation timing is inaccurate leading to disjointed experience

Engineering Contradiction:
Improveresponse speedVSAvoidsynchronization accuracy
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The system performs preliminary actions by detecting the user's inhalation through distance sensor data and predicting the exhalation timing in advance. The virtual smoke is prepared and timed to be displayed just before the predicted exhalation moment, ensuring both fast response and accurate synchronization with the user's actual breathing cycle.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If distance monitoring and prediction algorithms are implemented, then the synchronization accuracy is improved, but the device complexity increases

Engineering Contradiction:
Improvesynchronization accuracyVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The electronic device uses its existing distance sensor to self-monitor the user's breathing actions without requiring additional specialized sensors. The processor internally performs the prediction algorithm using the distance data, making the system self-sufficient and avoiding increased hardware complexity while achieving accurate synchronization.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If multiple sensors and prediction algorithms are used, then the immersion experience is enhanced, but the processing time and computational load increase

Engineering Contradiction:
Improveimmersion experienceVSAvoidprocessing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system replaces complex mechanical sensing with optical/distance-based sensing. The distance sensor continuously monitors position changes that indicate breathing, and the processor uses algorithmic prediction rather than complex signal processing, reducing computational load and processing time while maintaining high immersion quality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
