Wearable Vision Correction via Dynamic Display Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable technologies, such as smart glasses, fail to adequately address vision defects, particularly higher order and dynamic visual aberrations that change with eye accommodation and gaze direction, which are not correctable by traditional glasses or contact lenses.
Innovation Solution
A system and method that uses feedback from user responses to stimuli, such as eye movements and images, to determine defective visual field portions and adjust wearable device configurations, including dynamic display portions, to enhance or correct vision by generating enhanced images and adjusting display settings like transparency, brightness, and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional glasses or contact lenses are used, then simple refractive errors can be corrected, but higher order and dynamic visual aberrations cannot be addressed
Solution Approach 1:
The patent employs dynamic displays that can change transparency, brightness, and content in real-time based on the user's accommodation state and gaze direction. This allows the system to adapt to dynamic visual aberrations that change with eye movement and focus, rather than using static corrective lenses.
Solution Approach 2:
The system modifies display parameters (transparency, brightness, contrast, content) dynamically to compensate for visual aberrations. By changing these parameters based on real-time eye tracking and accommodation detection, the system can correct higher order aberrations that traditional lenses cannot address.
2Reliability
If wearable technologies are designed to assist visually impaired users, then vision enhancement is provided, but the devices do not adequately address dynamic aberrations that change with accommodation and gaze
Solution Approach 1:
The system incorporates real-time feedback loops that monitor the user's accommodation state, gaze direction, and visual responses. This feedback is used to dynamically adjust display characteristics, ensuring reliable vision correction that adapts to changing visual conditions rather than relying on fixed correction parameters.
Solution Approach 2:
The wearable device autonomously adjusts its display parameters based on real-time detection of the user's eye characteristics and accommodation state, without requiring manual intervention. The system self-regulates transparency, brightness, and content delivery to maintain optimal vision correction across varying conditions.
3Area of stationary object
If the visual field is enhanced to cover defective portions, then the field of view is expanded, but the common region may not provide sufficient coverage for all visual needs
Solution Approach 1:
The patent divides the visual field into multiple regions (common region, peripheral regions, defective portions) and processes each region differently. By segmenting the visual field and applying region-specific enhancement strategies, the system achieves both broad coverage and precise defect determination without relying solely on the limited common region.

AI summary
In certain embodiments, a user's field of view may be increased and/or modified. In some embodiments, views of a scene may be obtained via a wearable device. A first region of the scene may be determined, where the first region is common to the views and represented in the views at proximate a center of each of the views. For each view of the views, a second region of the scene may be determined, where the second region is represented in the view and related to peripheral vision of the user. A modified view may be generated based on (i) a portion of at least one of the views that corresponds to the common first region and (ii) portions of the views that correspond to the second regions such that the modified view comprises a representation of the common first region and representations of the second regions.
