Virtual Reality Glasses Height Adjustment for Vehicle Interior Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality systems face challenges in providing a realistic representation of virtual motor vehicles, particularly in interior views, due to inconsistent height positioning of the observer within the vehicle, which affects the perceived realism and comfort of the virtual experience.
Innovation Solution
The method involves using virtual reality glasses with a detection device to adjust the height of the virtual observation position based on the actual height of the glasses and the vehicle model, switching between interior and exterior views seamlessly, and utilizing a seat occupancy sensor to control the display, ensuring that the observer's perspective is vehicle-specific and realistic, preventing virtual collisions with the vehicle's interior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed virtual observation position is used for all vehicle models, then the system complexity is reduced, but the realism and comfort of the virtual experience deteriorates
Solution Approach 1:
The virtual observation position is made dynamic rather than fixed. The system automatically adjusts the virtual observation position based on the detected actual position of the user and the specific vehicle model being viewed, allowing the observation position to adapt in real-time to different conditions while maintaining a relatively simple system architecture
Solution Approach 2:
The system changes the parameters of the virtual observation position (coordinates, height, angle) based on input parameters such as the user's actual position, the vehicle model type, and the viewing context. This allows the same system to provide optimized viewing experiences for different vehicle models without requiring multiple separate systems
2Manufacturing precision
If the virtual observation position is adjusted for each vehicle model, then the realism of interior views is improved, but the device complexity increases
Solution Approach 1:
The system stores predefined parameter sets for different vehicle models (coordinates, observation angles, height adjustments) and automatically selects and applies the appropriate parameters based on the detected vehicle model. This allows realistic interior views for each specific vehicle type while keeping the system relatively simple through parameter-based adaptation rather than complex structural changes
Solution Approach 2:
The system applies different observation position parameters locally for each vehicle model and interior view context, rather than using a single global configuration. Each vehicle model receives optimized local parameters tailored to its specific geometry and interior layout, improving realism without requiring complete system redesign
3Ease of operation
If the system switches between interior and exterior views based on seat occupancy, then the user comfort is improved, but the transition smoothness may be affected by abrupt changes
Solution Approach 1:
The system dynamically transitions between interior and exterior views based on real-time detection of seat occupancy status. When the user stands up or sits down, the system automatically switches the view mode, making the virtual experience adapt to the user's physical state and improving comfort through context-aware operation
Solution Approach 2:
The system uses feedback from seat occupancy sensors to automatically trigger view transitions. The sensor detects whether the user is seated or standing and feeds this information back to the control system, which then adjusts the virtual view accordingly, creating a closed-loop system that responds to user state changes
4Device complexity
If the virtual observation position does not account for actual glass height, then the system simplicity is maintained, but the immersion and realism of the virtual experience deteriorates
Solution Approach 1:
The system automatically detects the user's actual position and uses this information to self-adjust the virtual observation position, eliminating the need for manual configuration or complex calibration procedures. The system serves itself by using sensor data to optimize the viewing experience automatically
Solution Approach 2:
The system integrates multiple functions into a single unified approach: position detection, parameter calculation, and view rendering all work together in one system. The same detection mechanism serves both to locate the user and to determine the appropriate virtual observation position, reducing overall system complexity while improving immersion

AI summary
The invention relates to a method for operating a virtual reality system (10) in which a virtual motor vehicle (24, 32) is displayed from a virtual observation position (28) by virtual reality glasses (12) worn by a person (20). If said virtual motor vehicle (24, 32) is displayed in an interior view, a height (h) of the virtual observation position (28) is set depending on a height position of the virtual reality glasses (12) detected by a detection device (16), and depending on the vehicle model of the virtual motor vehicle (24, 32) on display; if said virtual motor vehicle (24, 32) is displayed in an exterior view, the height (h) of the virtual observation position (28) is set depending on the detected height position of the virtual reality glasses (12) but independently of the vehicle model. The invention also relates to a virtual reality system (10) having virtual reality glasses (12).
