Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality display systems face challenges in providing a comfortable and natural presentation of virtual image elements within the user's vision field, especially in mixed reality scenarios where virtual objects need to interact with real-world objects.
Innovation Solution
A head-mounted display system that projects light into the user's eye to display augmented reality image content, featuring a frame with a transparent display portion that transmits environmental light, environmental sensors, and processing electronics that sense user focus and alter the perception of real or virtual objects within the user's vision field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual image elements are presented in augmented reality to enhance user engagement, then the AR experience becomes more immersive, but the presentation becomes less comfortable and natural
Solution Approach 1:
The system applies different image processing operations to different regions of the visual field. Virtual image elements in the central region receive enhanced rendering with increased brightness, saturation, and contrast, while peripheral regions maintain natural appearance. This localized differentiation allows immersive AR content delivery without compromising overall visual comfort.
Solution Approach 2:
The system dynamically adjusts the rendering of virtual elements based on user eye position and focus. When the user looks at a virtual object, that element receives enhanced processing; when the user shifts attention, the enhancement follows. This dynamic adaptation creates an immersive experience that responds naturally to user behavior, maintaining comfort while enhancing engagement.
2Adaptability or versatility
If virtual objects are integrated into the natural world in mixed reality scenarios, then the MR scenario becomes more realistic, but the integration complexity increases
Solution Approach 1:
The system processes different regions of the visual field with different operations. Virtual objects in the central vision region undergo enhanced rendering with adjusted brightness, saturation, and contrast, while peripheral regions and real-world backgrounds maintain their natural appearance. This selective processing achieves realistic integration without requiring complex system-wide modifications.
Solution Approach 2:
The system modifies specific parameters of virtual image elements (brightness, saturation, contrast, size) based on their location and the user's focus. By dynamically adjusting these parameters, the system creates realistic integration between virtual and real objects, making virtual elements appear naturally embedded in the environment without requiring complex physical integration.
3Manufacturing precision
If image content is enhanced in the central vision region to improve focus, then the focused object becomes more prominent, but the peripheral vision quality may be compromised
Solution Approach 1:
The system applies enhanced image processing operations specifically to the central region of the visual field where the user's focus is directed. Virtual elements in this region receive increased brightness, saturation, and contrast enhancement. Meanwhile, peripheral regions are processed with minimal or no enhancement, preserving their natural appearance and ensuring adequate peripheral vision coverage without compromising overall visual field quality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enhances the rendering of virtual objects and de-emphasizes surrounding real-world imagery, providing an improved augmented reality experience by altering image content, object movement, and background intensity based on user focus and intent.
Implementation Method 1
a head-mounted display disposed on the frame, the display configured to project light into the user's eye to present image content to the user's vision field
Implementation Method 2
at least a portion of the display being transparent and disposed at a location in front of the user's eye when the user wears the head-mounted display such that the transparent portion transmits light from a portion of the environment in front of the user to the user's eye
