Mixed-Reality Visor Dynamic View Control for IFR Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional View-Limiting Devices (VLDs) used in Instrument Flight Rules (IFR) training fail to effectively replicate the dynamic and unpredictable weather conditions, leading to pilot disorientation and increased risk of accidents due to inadequate realism and control over simulated conditions.
Innovation Solution
A Mixed-Reality (MR) visor headset system that uses see-through camera technology, sensors, and computer-generated imagery to dynamically control and modify the pilot's view, providing a more realistic and controlled IFR training experience by simulating various weather conditions and external visibility scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional View-Limiting Devices (VLDs) are used for IFR training, then the training setup is simple and equipment is basic, but the training realism is insufficient and pilot disorientation occurs
Solution Approach 1:
The patent uses cameras to capture real-world views and displays them on screens within the visor, creating a copied representation of external environments. This allows realistic simulation of various weather conditions and visibility scenarios without requiring actual hazardous conditions, thereby improving training effectiveness while maintaining safety.
Solution Approach 2:
The mixed-reality visor acts as an intermediary between the pilot and the external environment. It selectively blocks certain views while allowing others, and can superimpose additional visual information. This mediator approach enables controlled exposure to realistic conditions while preventing actual disorientation and maintaining training safety.
2Reliability
If VLDs block all external views for IFR training, then instrument reliance is improved, but pilot spatial awareness deteriorates
Solution Approach 1:
The visor selectively blocks views in certain directions while maintaining visibility in others. Different regions of the visor have different optical properties - some areas block external views to force instrument reliance, while other areas allow selective viewing to maintain spatial awareness. This local differentiation resolves the contradiction between instrument proficiency and spatial orientation.
Solution Approach 2:
The visor's blocking properties are dynamic rather than static. The system can adjust which areas block views based on training phase, pilot performance, and specific training objectives. This dynamic control allows the system to adaptively balance instrument reliance and spatial awareness development throughout the training process.
3Adaptability or versatility
If VLDs are used to simulate IMC conditions, then training coverage is limited to static conditions, but weather dynamics and unpredictability are lost
Solution Approach 1:
The visor system dynamically adjusts which external views are blocked and which are visible, allowing simulation of varying weather conditions including dynamic changes in visibility, cloud cover, and precipitation. The system can transition between different weather scenarios and adjust conditions in real-time based on training requirements, providing both adaptability and control.
Solution Approach 2:
The system captures real external environments through cameras and displays them selectively through the visor, creating copied representations of various weather conditions. This allows realistic simulation of dynamic weather scenarios including cloud formations, precipitation, and visibility changes without requiring actual hazardous weather, thereby achieving both versatility and safety.
4Reliability
If see-through camera technology is implemented in the visor, then view control and realism are improved, but device weight and complexity increase
Solution Approach 1:
The system uses cameras to capture external views and displays them through transparent elements in the visor. This copying approach allows accurate view control and realistic simulation while keeping the visor structure relatively simple. The camera and display components are integrated into the visor housing, minimizing additional weight compared to fully opaque VR headsets.

AI summary
A Mixed-Reality Visor (MR-Visor) system and method utilizing regional signaling and environmental sensor feedback for replicating restricted external visibility during operation of manned vehicles, such as marine or aircraft. Electromagnetic energy transfer is used to accurately define cabin window regions and enable the user to reliably limit, modify and/or block associated exterior views from the vehicle while maintaining visibility of the cabin interior. In the case of aircraft pilot training, the MR-Visor can be worn by a pilot to replicate Instrument Meteorological Conditions (IMC) and other challenging scenarios.
