Air Flow Generator for AR VR Wind Scent Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented and virtual reality technologies primarily focus on visual and auditory aspects, neglecting other sensory experiences such as wind, smell, and tactile sensations, which are integral to immersive experiences.
Innovation Solution
Implementing air flow generators on head-mounted displays (HMDs) and controllers to simulate wind effects and scent, with sensors and markers determining the position and orientation of the air flow generators to direct airflow and scents in synchronization with AR/VR content, enhancing the sensory experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If air flow generators are added to HMDs to provide wind and scent simulations, then sensory experience is enhanced, but device complexity increases
Solution Approach 1:
The patent combines multiple sensory output functions (air flow generation, scent delivery) into a single integrated HMD device. The air flow generator and scent delivery mechanism are merged into the head-mounted display structure, allowing simultaneous provision of visual, tactile, and olfactory stimuli through one device rather than separate systems.
Solution Approach 2:
The HMD is transformed from a single-function visual display device into a multi-sensory platform. The same device that provides visual AR/VR content also generates wind effects and delivers scents, making it a universal sensory interface that handles multiple types of stimulus delivery through integrated components.
2Adaptability or versatility
If air flow generators are integrated into HMDs and controllers, then user engagement is enhanced, but device weight increases
Solution Approach 1:
The sensory stimulation system is divided into multiple independent units: air flow generators in the HMD, additional air flow generators in controllers, and scent delivery mechanisms. This segmentation distributes the weight across multiple components rather than concentrating all sensory functions in the head-mounted portion, reducing the immediate weight burden on the user's head.
Solution Approach 2:
The patent extends the sensory system beyond the traditional head-mounted dimension by incorporating controllers held in the user's hands. This adds a spatial dimension to weight distribution, moving some sensory components from the head axis to the hand-held controller axis, thereby balancing the overall weight distribution across the user's body.
3Measurement precision
If sensors and markers are used to determine position and orientation of air flow generators, then airflow direction precision is improved, but system complexity increases
Solution Approach 1:
The system continuously monitors the position and orientation of the HMD and controllers using sensors and markers, then uses this feedback information to dynamically adjust the direction of air flow generators. This closed-loop feedback mechanism ensures that airflow is always directed accurately toward the user's face regardless of device movement, maintaining precision through real-time correction.
Solution Approach 2:
The patent introduces sensors and markers as intermediary elements that mediate between the physical movement of the device and the control of air flow direction. These intermediaries translate complex spatial movements into simplified control signals for the air flow generators, reducing the computational complexity while maintaining measurement precision.

AI summary
An air flow generator may be implemented on an augmented reality (AR) or virtual reality (VR) controller or head-mounted display (HMD) through which an AR or VR experience is presented. Based on content upon which the AR or VR experience is based, air flow effects can be provided by the air flow generator. In particular, desired air flow effect parameters based on or obtained from the content, can be used to enhance the AR or VR experience through generating air flow directed at a user of the HMD. The air flow generated by the air flow generator can be further enhanced by the addition of liquid and/or scented additives.
