Helmet Display System Documentation Navigation via Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aeronautical helmet display systems fail to efficiently manage and display documentation during flight, requiring pilots to divert attention from external vision and lose information provided by the display system when consulting paper or digital documentation.
Innovation Solution
A helmet display system that conditionally displays aeronautical documentation based on helmet orientation, allowing data to be fixed in a reference frame and navigated through by adjusting the helmet posture, with documentation appearing centered and uppermost in the visual field, enabling seamless consultation without significantly modifying the existing system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the pilot consults paper or digital documentation during flight, then the pilot can access aeronautical information, but the pilot must divert attention from external vision and lose information provided by the display system
Solution Approach 1:
The patent merges the documentation display with the helmet display system by projecting documentation images onto the combiner surface, allowing both external vision and documentation to be viewed simultaneously through the same optical path, eliminating the need to switch between separate documentation sources and the helmet display
Solution Approach 2:
The combiner acts as an intermediary surface that reflects or transmits documentation images from the display device into the pilot's field of view through the helmet, enabling documentation access without blocking the external landscape view
2Adaptability or versatility
If the helmet display system projects collimated images superimposed on the external landscape, then the display information is visible, but the system cannot efficiently manage and display documentation during flight
Solution Approach 1:
The helmet display system is extended to perform multiple functions: it displays both traditional flight instrumentation/symbology and aeronautical documentation through the same optoelectronic display assembly and combiner, eliminating the need for separate documentation systems
Solution Approach 2:
The system dynamically adjusts documentation display based on detected helmet orientation, automatically controlling when and how documentation appears in the pilot's field of view based on head position and orientation parameters
3Ease of operation
If the documentation is displayed in the helmet display system, then the pilot can access information without diverting attention, but the documentation must be navigated through by adjusting helmet posture
Solution Approach 1:
The system uses the pilot's natural head movements and orientation changes as the input mechanism for navigating documentation, eliminating the need for separate controls or interfaces - the helmet's own motion serves as the navigation interface

AI summary
The invention concerns a system comprising a headset equipped with a display device and a system for detecting the position of the headset in relation to a known frame of reference. The display system comprises a document database and means for displaying and managing the document data depending on the position of the headset. The invention is characterized in that, once they have appeared, the data being structured in the form of pages (P1, P2), and a whole page being presented in the display device, the page-change towards the right or the left is brought about by modification of the headset position to the left or the right by at least a plurality of degrees.
