Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Challenges exist in producing augmented reality technologies that facilitate a comfortable, natural-feeling, rich presentation of virtual image elements amidst real-world imagery, as human visual perception systems are complex and difficult to integrate effectively.
Innovation Solution
A head-mounted display system that projects light to a user's eye, featuring a transparent portion to view the environment, environmental sensors, and processing electronics to alter user perception of real or virtual objects based on focus and intent, enhancing or de-emphasizing image content through techniques like altering contrast, brightness, and object movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual image elements are presented to enhance richness and integration with real-world imagery, then the augmented reality experience becomes more immersive and engaging, but the complexity of the visual presentation system increases and may cause user discomfort
Solution Approach 1:
The system applies different processing and presentation qualities to different regions of the visual field. Virtual image elements are selectively enhanced in specific locations while maintaining natural appearance in other areas, creating localized quality variations that improve integration without overwhelming the entire visual system
Solution Approach 2:
The visual presentation system dynamically adjusts parameters such as brightness, contrast, and opacity of virtual elements based on real-time environmental conditions and user behavior. This dynamic adaptation allows the system to maintain optimal integration quality without requiring complex static configurations
2Loss of information
If multiple virtual image elements are overlaid on real-world imagery to create rich AR experiences, then the informational content increases, but the naturalness and comfort of visual perception deteriorates
Solution Approach 1:
The system selectively enhances only certain aspects of virtual image elements rather than uniformly processing all elements. By applying enhancement partially to specific regions or properties, the system maintains informational richness while avoiding excessive processing that would create visual discomfort
Solution Approach 2:
The system introduces intermediary processing layers that mediate between raw virtual image data and final presentation. These intermediaries include transparency masks, blending modes, and adaptive opacity controls that smooth the integration between virtual and real-world elements, reducing visual harshness while preserving information
3Adaptability or versatility
If the head-mounted display projects light to display augmented reality content while maintaining transparency to view the environment, then the user can access both virtual and real-world imagery, but the optical system complexity increases
Solution Approach 1:
The optical system is divided into separate functional segments: a display component for projecting AR content and a transparent window portion for environmental viewing. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining dual functionality
Solution Approach 2:
The head-mounted display device integrates multiple functions into a single platform: it serves as both a display device for virtual content and a transparent window for real-world viewing. This multi-functionality eliminates the need for separate devices, reducing overall system complexity despite the sophisticated optics required
