Spatial Odor Control for VR Immersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the field of virtual reality, there is a demand for odor presentation methods that enhance realistic sensations, as existing technologies fail to effectively simulate odors in a manner that immerses users in a virtual environment.
Innovation Solution
An information processing device connected to an odor presentation device, which includes a spatial odor information acquisition section and an odor control section. The spatial odor information acquisition section measures and acquires odor data from a reproduction target space, and the odor control section instructs the odor presentation device to release odors perceivable in that space, synchronizing with the user's attention direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional odor presentation methods are used, then the system structure remains simple, but the realistic sensation and immersion in virtual environment are insufficient
Solution Approach 1:
The odor presentation is segmented into multiple directional components. The system divides the spatial environment into different directions and presents odors specific to each direction, matching the user's head orientation and attention direction. This segmentation enables realistic spatial odor reproduction without requiring an overly complex monolithic system.
Solution Approach 2:
The system adds a spatial directional dimension to odor presentation. Instead of uniform omnidirectional odor release, the patent introduces directional odor presentation based on the user's head orientation and attention direction, creating a three-dimensional olfactory experience that enhances realism without proportionally increasing system complexity.
2Measurement precision
If spatial odor information is acquired and processed, then the odor presentation accuracy is improved, but the information processing load increases
Solution Approach 1:
The system performs preliminary acquisition and organization of spatial odor information in advance. Odor information is collected and structured according to spatial directions before the user interacts with the system, enabling rapid retrieval and presentation during actual use without excessive real-time processing overhead.
Solution Approach 2:
The system uses feedback from the user's head orientation detection and attention direction information to dynamically adjust odor presentation. This feedback mechanism enables precise spatial odor matching while optimizing processing by only calculating odor presentation for relevant directions based on user orientation, reducing unnecessary computational overhead.
3Adaptability or versatility
If multiple odor presentation directions are implemented, then the immersion experience is enhanced, but the device structure becomes more complex
Solution Approach 1:
The odor presentation device is designed with multi-functionality to handle multiple directional presentations. A single device structure is configured to present odors in different directions by adjusting presentation parameters based on user head orientation and attention direction, rather than requiring separate dedicated devices for each direction. This universal design achieves comprehensive directional coverage without proportionally increasing device complexity.

AI summary
Provided is an information processing device to be connected to an odor presentation device that presents an odor to a user. The information processing device acquires spatial odor information indicative of an odor in a reproduction target space, and instructs, by using the acquired spatial odor information, the odor presentation device to present to the user an odor assumably perceivable in the reproduction target space.
