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.
Innovation Solution
A head-mounted display system that projects light into the user's eye, featuring a transparent portion to view the environment, environmental sensors, and processing electronics to alter user perception of objects based on focus and intent, enhancing or de-emphasizing image content through techniques like altering contrast, brightness, and opacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If virtual image elements are presented with high visibility and richness, then the augmented reality experience is enhanced, but the naturalness and comfort of the presentation deteriorates
Solution Approach 1:
The system applies different image processing techniques to different regions of the visual field. Virtual image elements receive enhancement processing (increased brightness, contrast, saturation) while real-world background elements receive natural or reduced processing. This local differentiation allows virtual elements to stand out clearly without overwhelming the entire visual scene, maintaining both visibility and naturalness.
Solution Approach 2:
The system dynamically adjusts the presentation of virtual image elements based on user interaction state. When the user is not interacting, virtual elements are presented with subtle enhancements. When the user activates interaction (e.g., through gaze detection or hand gestures), the system temporarily increases the visibility and richness of virtual elements. This dynamic adjustment ensures that enhanced visibility is provided only when needed, maintaining comfort during normal viewing.
2Adaptability or versatility
If image processing techniques are applied to enhance virtual objects, then the interaction with virtual objects is improved, but the visibility of real-world features deteriorates
Solution Approach 1:
The system employs periodic or temporary enhancement of virtual objects rather than continuous enhancement. Image processing parameters such as brightness, contrast, and saturation are adjusted dynamically based on interaction detection. When interaction is detected, enhancement is applied; when interaction ceases, enhancement is reduced or removed. This periodic action allows real-world features to remain visible during non-interaction periods while enabling enhanced virtual object interaction when needed.
3Loss of information
If the presentation of virtual image elements is enriched, then the augmented reality experience is more immersive, but the comfort and naturalness of the experience deteriorates
Solution Approach 1:
The system modifies multiple image parameters (brightness, contrast, saturation, sharpness) to enhance virtual image elements. By adjusting these parameters selectively applied to virtual objects rather than the entire scene, the system achieves rich and immersive presentation of virtual elements while maintaining the natural appearance of the real-world environment. This selective parameter modification prevents the discomfort that would result from overwhelming visual enhancement.

AI summary
A display system can include a head-mounted display configured to project light to an eye of a user to display augmented reality image content to the user. The display system can include one or more user sensors configured to sense the user and can include one or more environmental sensors configured to sense surroundings of the user. The display system can also include processing electronics in communication with the display, the one or more user sensors, and the one or more environmental sensors. The processing electronics can be configured to sense a situation involving user focus, determine user intent for the situation, and alter user perception of a real or virtual object within the vision field of the user based at least in part on the user intent and/or sensed situation involving user focus. The processing electronics can be configured to at least one of enhance or de-emphasize the user perception of the real or virtual object within the vision field of the user.
