Spatial Orientation Perception Measurement via Multisensory Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods are inadequate for measuring spatial orientation perception in complex situations, such as virtual reality sickness, transport sickness, and rehabilitation, as they fail to effectively quantify sensitivity across multiple sensory frames of reference.
Innovation Solution
A method that combines measurements from both visual and non-visual frames of reference, such as proprioceptive, vestibular, and prior knowledge, to calculate a sensitivity score using a multisensory integration model, and modifies these frames by adjusting exocentered spatial mass distribution, providing vibratory stimulation, or altering visual scenes to assess spatial orientation perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current measurement methods are used, then simplicity of measurement is maintained, but measurement precision in complex situations deteriorates
Solution Approach 1:
The measurement system is segmented into multiple independent frames of reference (visual, proprioceptive, vestibular, auditory) that can be measured separately and then integrated. Each frame of reference corresponds to a specific sensory modality, allowing precise measurement of spatial orientation perception across different sensory channels without requiring a single complex measurement device.
Solution Approach 2:
Multiple measurement results from different frames of reference are merged into a unified sensitivity score through a combination process. The patent combines measured values from visual, proprioceptive, vestibular, and auditory frames of reference to produce an integrated sensitivity score that represents overall spatial orientation perception capability in complex situations.
2Adaptability or versatility
If single-frame measurement is used, then measurement simplicity is maintained, but adaptability to complex situations deteriorates
Solution Approach 1:
The measurement system is designed with multi-functionality to assess spatial orientation perception across multiple sensory modalities simultaneously. The same measurement framework can evaluate visual, proprioceptive, vestibular, and auditory contributions to spatial orientation, making it universally applicable to various complex situations such as virtual reality sickness, transport sickness, and rehabilitation assessment.
Solution Approach 2:
The patent introduces an additional dimension of measurement by incorporating multiple frames of reference beyond the traditional single visual frame. This dimensional expansion from one sensory modality to multiple sensory modalities enables the system to capture the complexity of spatial orientation perception in diverse and challenging environments.
3Measurement precision
If visual frame of reference is used alone, then measurement simplicity is maintained, but measurement precision in multisensory situations deteriorates
Solution Approach 1:
The measurement procedure is segmented into separate assessment of visual, proprioceptive, vestibular, and auditory frames of reference. Each frame can be measured independently using standardized procedures, and the results are then combined to provide a comprehensive precision assessment of spatial orientation perception that accounts for multisensory integration.

AI summary
A method for measuring the perception of spatial orientation of a person comprising the steps of: modifying a first non visual frame of reference and providing a second non visual frame of reference and measuring the value of the parameter representative of the perception of spatial orientation; modifying a first visual frame of reference so as to provide a second visual frame of reference and measuring the value of the parameter representative of the perception of spatial orientation; combining the measured values of the parameters representative of the perception of spatial orientation of preceding steps so as to obtain a value representing the sensitivity of the person referred to a scale of sensitivity to perception of spatial orientation.
