## 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.

## Claims

### Claim at position 1

-10. (canceled)

### Claim 11

A method of assisting a user to maintain fixation at a target point when the user has a visual field defect, comprising the steps of:
capturing real-time video images with a camera of a visual aid device;
continuously processing the real-time video images to produce warped real-time video images;
continuously displaying the warped real-time video images on a display of the visual aid device; and
displaying a fiducial pattern over the warped real-time video images on the display, the fiducial pattern comprising at least two intersecting lines that pass through the visual field defect.

### Claim 12 (depends on 11)

The method of claim 11, wherein the fiducial pattern comprises two lines that each connect at opposite corners of the display.

### Claim 13 (depends on 12)

The method of claim 12, wherein the fiducial pattern further comprises an additional two lines that each connect at midpoints of opposite sides of the display.

### Claim 14 (depends on 11)

The method of claim 11, wherein the fiducial pattern comprises a plurality of asymmetric lines that meet at a central fixation point.

### Claim 15 (depends on 11)

The method of claim 11, wherein the fiducial pattern is independent from the warped real-time video images and appear undistorted.

### Claim 16 (depends on 11)

The method of claim 11, further comprising causing the fiducial pattern to disappear in response to a user input.

### Claim 17 (depends on 11)

The method of claim 11, wherein the visual aid device is configured to be worn on a head of the user.

### Claim 18 (depends on 17)

The method of claim 17, wherein the visual aid device comprises an AR/VR device.

### Claim 19 (depends on 11)

The method of claim 11, further comprising animating the fiducial pattern.

### Claim 20 (depends on 19)

The method of claim 19, wherein animating the fiducial pattern comprises animating a “crawling dots” characteristic in the fiducial pattern.

### Claim 21 (depends on 11)

The method of claim 11, further comprising, in response to a user input, independently adjusting the fiducial pattern to compensate for the user's visual field defect.

### Claim 22 (depends on 11)

The method of claim 11, wherein the visual field defect of the user comprises a central field defect.
