Multisensory VR System for Comprehensive User Performance Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for human-computer interaction in virtual reality are limited by their focus on the central visual field, failing to comprehensively assess human performance and cognitive/multisensory reactions, which are essential for understanding overall user interaction with interactive systems.
Innovation Solution
A virtual reality system that incorporates a signal control unit and sensory stimulation unit to process and communicate sensory information, including visual, auditory, tactile, olfactory, and thermal signals, to create immersive interactions by stimulating the user's actual body based on virtual environment experiences, using a brain-computer interface for device control and sensory feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the system focuses only on the central visual field for interaction, then the system complexity is reduced, but the comprehensiveness of human performance evaluation deteriorates
Solution Approach 1:
The patent transitions from evaluating only the central visual field (2D limitation) to incorporating the peripheral visual field and multiple sensory modalities (expanding dimensions). This allows comprehensive assessment of human performance by adding spatial and sensory dimensions beyond the traditional central visual focus.
Solution Approach 2:
The system integrates multiple sensory evaluation capabilities (visual, auditory, tactile, olfactory, thermal) into a single interactive platform. This multi-functional approach enables comprehensive human performance assessment across different sensory modalities simultaneously, resolving the contradiction between system simplicity and evaluation comprehensiveness.
2Loss of information
If multiple sensory modalities are integrated into the interactive system, then the comprehensiveness of sensory information communication is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple sensory stimulation devices (visual displays, auditory speakers, tactile actuators, olfactory generators, thermal elements) into an integrated interactive system. By merging these components under unified control, the system achieves comprehensive sensory information communication while managing complexity through centralized coordination rather than separate independent systems.
Solution Approach 2:
The system employs an intermediary processing layer that receives input signals, coordinates appropriate sensory responses across multiple modalities, and delivers integrated output to the user. This intermediary structure manages the complexity of multi-sensory integration by providing a centralized control mechanism that orchestrates various sensory channels.
3Ease of operation
If the system uses only central visual field interaction, then the ease of operation is maintained, but the realism of virtual reality experience deteriorates
Solution Approach 1:
The system segments the visual field evaluation into central and peripheral components, allowing independent optimization of each. The central visual field maintains ease of operation for primary interactions, while the peripheral visual field and additional sensory modalities enhance realism without requiring complex user control, thus resolving the contradiction between operational simplicity and experiential realism.
