Adapting HMD Content via User Vital Parameter Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional VR systems using HMD devices often cause side effects such as seizures, eye strain, nausea, and motion sickness due to immersive content, which can be exacerbated by variations in user vital parameters like heart rate and blood pressure, without adequate adaptation to individual user behaviors and health conditions.
Innovation Solution
A method and system that automatically adapts VR content on HMD devices by monitoring user vital parameters and behavioral data to dynamically modify immersive views, switching to non-immersive modes when threshold criteria are met, using a processor unit, memory, and immersive experience managing unit to generate modified views based on user-specific data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If immersive VR content is displayed on HMD device, then user engagement and realism are improved, but user health safety deteriorates due to seizures, eye strain, nausea, and motion sickness
Solution Approach 1:
The system continuously monitors user vital parameters (heart rate, blood pressure, galvanic skin response) during VR content consumption and uses this feedback to dynamically adjust the displayed content. When parameters indicate discomfort or exceed thresholds, the system automatically modifies or pauses the immersive content, creating a closed-loop control system that balances engagement with health safety.
Solution Approach 2:
The VR content delivery is made dynamic rather than static. The system adapts the immersive experience in real-time based on user physiological responses, adjusting content intensity, depth effects, and duration according to the user's current health state, thereby maintaining safety while preserving engagement when conditions permit.
2Object-affected harmful factors
If vital parameters monitoring and content adaptation is implemented, then user health safety is improved, but device complexity increases
Solution Approach 1:
The HMD device integrates multiple functions into a single platform: it serves as both the VR content display device and the physiological monitoring system. Sensors for detecting heart rate, blood pressure, and galvanic skin response are built into the HMD, eliminating the need for separate monitoring equipment and reducing overall system complexity despite the added functionality.
Solution Approach 2:
The system combines content delivery and health monitoring functions into a unified system. The processor unit that manages VR content rendering also handles physiological data analysis and adaptation decisions, merging computational tasks to reduce the number of separate components needed.
3Object-affected harmful factors
If real-time content modification is performed based on behavioral parameters, then user comfort is improved, but processing time and productivity are reduced
Solution Approach 1:
The system pre-establishes threshold criteria for vital parameters and pre-defines adaptation strategies for different health states. When monitoring begins, these pre-set rules enable rapid automated decisions without requiring complex real-time analysis, thus maintaining user comfort while minimizing processing delays.
Solution Approach 2:
The system performs self-adjustment of VR content based on automated analysis of physiological data against pre-defined thresholds. The processor unit independently makes adaptation decisions without requiring external intervention or complex real-time computation, enabling quick response to changing user conditions while maintaining processing efficiency.
