Abstract
Adaptive Control Driven System/ACDS 99, supports visual enhancement, mitigation of challenges and with basic image modification algorithms and any known hardware from contact lenses to IOLs to AR hardware glasses, and enables users to enhance vision with user interface based on a series of adjustments that are applied to move, modify, or reshape image sets and components with full advantage of the remaining useful retinal area, thus addressing aspects of visual challenges heretofore inaccessible by devices which learn needed adjustments.
Core Innovation
The invention presents images to a user with a visual field defect using a visual aid device. An initial working boundary of a visual defect model overlaps at least a portion of the user's visual field defect and is displayed on the device, and user input modifies at least one parameter of the initial working boundary to generate a modified working boundary.
The device captures real-time video images with a camera and continuously processes the real-time video images to produce warped real-time video images. The warped real-time video images are continuously displayed on the display within the modified working boundary of the visual defect model, creating a presentation of video content constrained by the user-modified boundary.
The user selects a point on the initial working boundary, and a line extending from the visual defect model through the selected point is presented on the display. The receiving step includes user input that modifies the initial working boundary radially inwards or radially outwards along the line to more accurately capture the user's visual field defect.
Claims Coverage
The independent claim covers an interactive visual defect model boundary, real-time camera capture with continuous warping, and boundary refinement via a point-and-line radial inward/outward adjustment.
Interactive working boundary of a visual defect model
Presenting an initial working boundary of a visual defect model that overlaps at least a portion of the user's visual field defect; receiving at least one input from the user that modifies at least one parameter of the initial working boundary to generate a modified working boundary.
Real-time warped video display within the modified boundary
Capturing real-time video images with a camera; continuously processing the real-time video images to produce warped real-time video images; continuously displaying the warped real-time video images on the display within the modified working boundary of the visual defect model.
Point selection with radial inward/outward boundary adjustment
Receiving an input from the user selecting a point on the initial working boundary; presenting, on the display, a line extending from the visual defect model through the point; receiving at least one input that modifies the initial working boundary radially inwards or radially outwards along the line to more accurately capture the user's visual field defect.
Boundary geometry and appearance refinements
Refining the method with additional constraints or visual characteristics of the initial working boundary and its overlap, including circular initial working boundary and a visual defect model appearance when it overlaps the user's visual field defect as distorted.
Overall claim coverage centers on interactively modifying a visual defect model boundary, using continuous processing to warp real-time video images and display them within that modified boundary, and refining the boundary by selecting a point and adjusting the boundary radially inward or outward along a line.
Stated Advantages
More accurately captures the user's visual field defect.
Reduces the appearance and amount of distortion in the visual field defect shown to the user.
Documented Applications
Presenting images to a user with a visual field defect using a visual aid device.
