Solution Overview
Problem
Conventional augmented reality systems for firefighters are not compatible with existing helmets and self-contained breathing apparatus (SCBA), limiting their effectiveness in low-light, smoke-filled environments where visibility is poor, and fail to aid in identifying and locating people.
Innovation Solution
An augmented reality display system that integrates thermal imaging with edge detection image processing, compatible with various protective headgear, including SCBA, to highlight human temperature objects, enhancing visibility and location of individuals in challenging environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional augmented reality goggles are designed to provide visual overlay, then the user can see augmented reality information, but the device becomes bulky and incompatible with existing headwear or facial items
Solution Approach 1:
The system separates the augmented reality display into two independent components: a compact AR display unit that attaches to headwear, and a separate processing unit that can be worn on the body or mounted elsewhere. This segmentation allows the AR components to be small and compatible with helmets while the processing burden is distributed elsewhere.
Solution Approach 2:
The AR display unit is designed with universal mounting capabilities that can attach to various types of headwear including helmets, caps, and other protective gear without requiring modification to the headwear itself. This multi-functional attachment system enables compatibility across different headwear types while keeping the display unit compact.
2Measurement precision
If thermal imaging is integrated into augmented reality systems, then the ability to identify people in poor visibility improves, but the device complexity increases
Solution Approach 1:
The system merges thermal imaging technology with augmented reality display in a single integrated unit that attaches to headwear. By combining these functions in one compact module rather than separate systems, the overall device complexity is managed while maintaining enhanced detection capabilities for identifying people in poor visibility conditions.
Solution Approach 2:
The system uses an image processing algorithm as an intermediary that automatically processes thermal imaging data to detect and highlight human figures. This intermediary processing layer simplifies the complexity by automating the analysis rather than requiring manual interpretation of raw thermal data, making the system more user-friendly despite the advanced technology involved.
3Illumination intensity
If the display screen is made transparent for augmented reality overlay, then the user can see through it, but the visibility of displayed information decreases
Solution Approach 1:
The display screen utilizes electrochromic or liquid crystal technology that can dynamically change its optical properties between transparent and opaque states. By adjusting the transparency parameter based on environmental conditions and user needs, the system maintains both the ability to see through the display when needed and the visibility of displayed information when required.
