Solution Overview
Problem
Existing virtual reality and augmented reality technologies fail to accurately synchronize the implementation of virtual smoke with a user's exhalation, leading to a sense of discontinuity in the smoking experience.
Innovation Solution
A method of predicting a virtual smoke implementation timepoint by monitoring changes in distance or capacitance between an electronic device and a user, using sensors to transmit a control signal to a VR device for synchronized virtual smoke display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual smoke is displayed in real-time during VR/AR, then the immersion and realism of the smoking experience are improved, but the synchronization accuracy with user exhalation is poor, creating perceptible differences
Solution Approach 1:
The system performs preliminary detection of user inhalation actions through sensors (capacitance, distance, or other sensors) and predicts the exhalation timing before it actually occurs. This predictive approach allows the virtual smoke to be displayed at the optimal moment, achieving synchronization without waiting for the exhalation to naturally occur.
Solution Approach 2:
The system continuously monitors user actions through sensors and adjusts the virtual smoke display timing based on the detected inhalation patterns. This feedback loop ensures that the virtual smoke synchronization adapts to the user's actual breathing rhythm, improving both accuracy and realism.
2Measurement precision
If sensors are added to detect user actions for better synchronization, then the timing accuracy is improved, but the device complexity increases
Solution Approach 1:
The system uses existing sensors (capacitance sensors, distance sensors, or other sensors already present in the VR/AR device) for multiple purposes: detecting both inhalation and exhalation actions, and using this data for predictive timing. This eliminates the need for separate dedicated sensors, reducing overall system complexity while maintaining precision.
Solution Approach 2:
The system changes the detection parameter from direct exhalation detection to inhalation detection with predictive timing. By detecting inhalation (which is easier to measure with existing sensors) and predicting exhalation timing based on the inhalation duration and pattern, the system achieves precise synchronization without requiring complex exhalation detection mechanisms.
