AR Skydiving Helmet Visor Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Skydivers require additional information during skydiving activities that existing helmets with altimeters cannot effectively provide in a non-distracting manner, necessitating a system to display relevant data conveniently.
Innovation Solution
An augmented reality (AR) skydiving helmet with a visor display that overlays virtual objects with real-world environment views, using a detection unit with GPS, IMU, and altimeter to provide critical information like drop zones, waypoints, and altitude, without the need for additional equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If additional information is provided to the skydiver during skydiving activity, then the skydiver gains better navigation and safety data, but the skydiver may become distracted from the skydiving activity
Solution Approach 1:
The patent overlays virtual information objects onto the three-dimensional real-world view through the visor, allowing information to be presented in the same spatial dimension as the environment rather than adding a separate viewing dimension. This integrates information delivery with environmental perception, providing data without requiring the skydiver to shift attention to a different display plane
Solution Approach 2:
The transparent visor acts as an intermediary medium that simultaneously transmits the real-world visual environment and displays virtual information objects. This mediator allows both the environment and information to coexist in the same field of view, eliminating the need to choose between viewing the environment or receiving information
2Loss of information
If a transparent visor is used to display information, then the skydiver can view the real-world environment and information simultaneously, but the display screen may reduce the amount of light from the real-world environment reaching the skydiver's eyes
Solution Approach 1:
The patent employs a transparent visor that functions as a thin film display medium. This thin film structure minimizes light absorption and scattering, allowing maximum transmission of real-world environmental light while still enabling the display of virtual information objects on its surface
Solution Approach 2:
The transparent visor utilizes optical properties that allow it to display information with minimal impact on light transmission. The display technology employed on the visor surface is designed to be visually unobtrusive, allowing the real-world environment to remain clearly visible while adding informational overlays
3Ease of operation
If virtual information objects are overlaid on the real-world view, then the skydiver can easily understand the information in context, but the system complexity increases due to integration of multiple sensors and display components
Solution Approach 1:
The helmet integrates multiple functions into a single system: the visor serves as both a protective shield and an information display surface, the transparent display medium functions as both environment transmitter and information carrier, and the integrated sensors provide both navigation data and display control capabilities. This multi-functionality reduces the need for separate equipment while enabling contextual information overlay
Solution Approach 2:
The patent combines the display function with the existing protective visor structure of the helmet, merging information delivery with head protection. The detection units, processing system, and transparent display are integrated into a unified system that operates as a single coherent unit rather than separate components
Data Source
AI summary
An Augmented Reality (AR) wearable display device is described. The device may be a skydiving helmet. The device may include a transceiver configured to receive a real-world environment view and a point of interest (POI) geolocation and POI altitude information. The device may further include a detection unit configured to detect AR wearable display device trajectory information. The device may further include a processor configured to determine a POI location in the real-world environment view based on the POI geolocation and the POI altitude information and the AR wearable display device trajectory information. The processor may further generate an AR image by overlaying a virtual object associated with the POI on the real-world environment view based on the POI location. The processor may further render the AR image on a display screen associated with the AR wearable display device. The display screen may be a helmet visor.
