Wearable Scent Delivery Synchronization for Immersive VR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality (VR) systems lack precise control over scent delivery, limiting their integration into dynamic environments and preventing users from freely moving, as existing scent display devices are not compatible with most VR setups and do not synchronize scent release with user interactions or biometric data.
Innovation Solution
A system comprising a virtual reality component, a wearable scent delivery component, and a digital controller that synchronizes scent delivery with user interactions, biometric data, and environmental events, using sensors like respiration, heart rate, and movement to control scent release, ensuring precise timing and location-based delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If scent display devices are integrated into VR environments, then immersive experience is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple scent delivery mechanisms (heating element, fan, odorant reservoir) into a single integrated wearable device that synchronizes with VR environments. This merging approach enables comprehensive scent integration while managing complexity through unified design rather than separate components.
Solution Approach 2:
The wearable scent delivery device is designed to work with multiple VR environments and scenarios through programmable control. The device can deliver different scents at different times based on VR event triggers, making it universally applicable across various VR applications without requiring device modification.
2Measurement precision
If precise control over scent delivery timing is implemented, then synchronization with VR events is improved, but device complexity increases
Solution Approach 1:
The system uses biometric sensors to detect user physiological states (respiration, heart rate) and provides feedback to the controller, which then adjusts scent delivery timing accordingly. This feedback mechanism enables precise synchronization with VR events while managing complexity through adaptive control rather than rigid programming.
Solution Approach 2:
The device pre-loads multiple odorants into the reservoir and prepares heating elements before VR sessions begin. The controller is pre-programmed with synchronization algorithms that anticipate VR events, allowing precise scent delivery timing without requiring complex real-time decision-making during operation.
3Weight of moving object
If wearable scent delivery device is made lightweight, then user comfort is improved, but scent delivery capability is reduced
Solution Approach 1:
The device uses a small fan to generate airflow that carries scent molecules from the heating element to the user's nose. This pneumatic approach enables effective scent delivery with minimal odorant quantities, allowing lightweight construction without sacrificing delivery capability.
Solution Approach 2:
The scent delivery mechanism is positioned locally near the user's nose with a focused delivery path. The heating element and fan are configured to create a concentrated scent plume that reaches the olfactory region efficiently, maximizing delivery impact while minimizing the amount of odorant needed and reducing overall device weight.
4Measurement precision
If biometric sensors are integrated to control scent delivery, then synchronization accuracy is improved, but device complexity increases
Solution Approach 1:
Multiple biometric sensors (respiration detector, heart rate monitor) are merged into a single wearable unit with unified processing. The sensors work together to detect physiological states that indicate when scent delivery should occur, improving synchronization accuracy while managing complexity through integrated design.
