Systems for augmented reality visual aids and tools
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.
1. A method of providing autonomous enhancements to a video output of a visual aid device, comprising:
obtaining real-time images of a scene with the visual aid device;
evaluating a motion component of the visual aid device;
determining a motion state of the visual aid device based on the motion component;
if the motion state indicates that a user of the visual aid device is engaged in head motions that exceed a motion threshold:
presenting first video images on a display of the visual aid device in a neutral setting with limited enhancements or adjustments applied to the real-time images;
if the motion state indicates that the user of the visual aid device is engaged in head motions that do not exceed the motion threshold:
locating text-like features in a high-acuity portion of the real-time images;
applying visual enhancements to at least the text-like features; and
presenting second video images including the visually enhanced text-like features on the display of the visual aid device.
2. The method of claim 1 , wherein when the motion state indicates that the user is engaged in head motions that do not exceed the motion threshold, applying visual enhancements to the text-like features that are optimized for reading.
3. The method of claim 2 , wherein the visual enhancements applied to the text-like images comprise color mapping to give high-contrast two-level images.
4. The method of claim 2 , wherein the visual enhancements applied to the text-like images comprise binarization to give high-contrast two-level images.
5. The method of claim 2 , wherein the visual enhancements applied to the text-like images comprise a tiered-radial warp.
6. The method of claim 5 , wherein the visual enhancements applied to the text-like images comprise a tiered-radial warp with moderate magnification.
7. The method of claim 1 , wherein when the motion state indicates that the user is engaged in head motions that do not exceed the motion threshold, applying visual enhancements to the text-like features that increase a size of the text-like features to a preferred text size.
8. The method of claim 1 , further comprising:
receiving an input from the user that a spotting configuration is desired; and
reducing a magnification of the second video images and restoring a more natural and less-distorted field-of-view.
