Definitions

  • the present invention relates generally to improvements in Augmented Reality (AR) glasses including using such glasses for medical purposes for the correction of vision defects, and more particularly to a system and methods for compensating for visual defects, for detecting the vision defects, capturing an image, modifying the image for correcting the visual defect, and displaying a modified image for that correction, and also for the correction of what prescription glasses would otherwise do.
  • AR Augmented Reality
  • This present invention also incorporates novel hardware and software applications related to the invention, including the application of smart contact lenses.
  • Macular degeneration AMD
  • macular hole and other FOV (Field of Vision) related blindness or vision defect conditions, such as central macular scar, histoplasmosis, end- stage glaucoma, Stargardt's disease, central serous retinopathy, myopic macular degeneration, diabetic macular edema, cystoid macular edema, macular holes, macular atrophy, central macular scar, histoplasmosis, macular hole, anterior ischemic optic neuropathy, and retinitas pigmentosa, are often irreversible.
  • peripheral receptors in the retina are usually still functioning, it is the purpose of this invention, in one embodiment for the medical application of AR glasses, then, to stretch, skew, and manipulate the image being projected on the eye to avoid the macula, and be directed to the retina's peripheral receptors. In this way, the entire image is projected on the functioning retinal receptors, and any involvement of the macula is avoided.
  • the method taught in this invention is how to create a matrix distortion of the entire image and project it onto the periphery of the eye, while avoiding the macula.
  • the patient by using "see through” glasses or lenses that provide a wide field of vision, upon which an augmented image can also be displayed, can have both real world and augmented visual information which corrects for the vision defect suffered delivered to the eyes.
  • This is an improvement to the existing art and a new "Mixed Reality" wearable invention.
  • the visually impaired patent can be introduced to both real world visual information and augmented information, at the same time, such that together the two separate inputs provide a "mixed reality" vision.
  • This can be accomplished, as taught herein, with virtually no latency, such that the augmented enhances the user/patient's remaining real-world experience eyesight.
  • the patient can still see some real world visual information with their peripheral eyesight so that the patient can move, walk, and navigate his or her immediate surroundings with as much surety and safety as the patent would otherwise have, and at the same time rely on the augmented reality of an augmented pixel/image moved video feed.
  • the present invention is aimed at one or more of the problems identified above.
  • the invention in general, in a first aspect, relates to a vision corrective wearable device which, in its preferred embodiment, uses Mixed Reality type of glasses/lenses together with new software and hardware to achieve the desired effect.
  • This patent teaches to manipulate an image or video to avoid unsighted areas, such as the damaged areas that result with macular degeneration or macular hole, and project the image on the glasses lenses where it can be viewed by the next nearest sighted areas of the eye. It also teaches to merge such augmented video back into real world images which can be viewed alongside the real-world images received without video by, typically, the periphery of the naked eye. It also teaches to correct for nearsightedness and farsightedness at the same time as the correction of the central vision.
  • the entire retina is the light and color sensitive tissue that lines the inside of the eye.
  • the retina functions in a manner similar to film in a camera, hence this invention supplements the retina's camera effect by providing an augmented, Mixed Reality duality of vision to the patient using both external camera(s) and display, as well as the eye's natural vision. Because it is important to make the augmented video or image hit as many cones as possible, the higher the rate of resolution, the better.
  • the preferred embodiment of the invention would cover at least 50 degrees of the Field of Vision (FOV) or greater. Although, the invention will work with a lesser FOV also.
  • FOV Field of Vision
  • the image to be displayed covers over the entire 120 degrees of normal eye vision, while in another aspect of the invention, the image is displayed on 90 degrees, 80 degrees, or 50 degrees FOV.
  • the image to be displayed is intended to be displayed on all or a portion of the lenses of Mixed Reality glasses, goggles, or other display techniques, where is extant both video and normal vision.
  • Part of the duality of the vision is the real-world vision that the patient sees where there is no augmented modified video, typically on the periphery of the lenses of the glasses and beyond that, simply the user's own unrestricted vision.
  • the other portion of the duality of vision is the augmented, modified video or picture which is typically, in the case of macular degeneration, focused on the portion of the eye closest to the central vision, concentrating manipulated pixels and images onto areas that are still sighted, and avoiding areas that are unsighted. Together, these make up a Mixed Reality augmented reality vision which helps correct for the defect of eye diseases like macular degeneration (all of which eye diseases are referred herein sometimes as "defects" or "deficits").
  • the optical elements in the eye focus an image onto the retina of the eye, using the lens, initiating a series of chemical and electrical events within the retina. Nerve fibers within the retina receive these signals and send electrical signals to the brain, which then interprets these signals as visual images.
  • all of us “see” an image upside down, since the eye bends the image through the lens, and the brain has the unique ability to "upright” the image in brain implemented natural simulation.
  • This invention uses this natural “simulation” created by the brain to "see” a whole picture or video, without any part missing, when in actuality there is a portion of the lens, which does not display an image.
  • this invention also employs the "brain-stitching" theory behind the natural blind spot, scotoma, or punctum caecum, which naturally exist in every human's eye.
  • This naturally occurring "hole” is the place in the visual field that corresponds to the lack of light- detecting photoreceptor cells on the optic disc of the retina where the optic nerve passes through the optic disc. Because there are no cells to detect light on the optic disc, this part of the eye's Field of Vision (FOV) is naturally occurring as unsighted and invisible to the human eye, as no visual information can be captured there.
  • FOV Field of Vision
  • This invention teaches that by removing and displacing pixels or images of pictures or video from a non-sighted portion of a defective macula to the area just surrounding the damaged portion of the macula, the brain will interpret the image as a whole, and dismiss the actual hole that is cut into the picture or video.
  • Computing software and chips create a modified cameral generated display image which corrects for the missing macular portion of the retina by not projecting any video or picture on the unsighted areas, and instead displaying the entire image or video on all remaining sighted areas.
  • This invention has discovered a new concept for the correction of defects like macular degeneration which supposes and enables the brain-stitching/natural brain simulation theory. It has been proven on one notable patient, Brig. Gen. Richard C. "Dick” Freeman (U.S.A.F. Ret.) who is one of the inventors here and one of the inventors who first invented streaming mobile video. General Freeman had macular degeneration, and upon wearing a device using the invention and its augmentations, could instantly "see” a nose on a face, which, due to the macular degeneration, has not been visible for years. The brain-stitching was, in his case, instant, and did not need to be "learned" by the brain.
  • the First Phase of the Image Manipulation Techniques is the "hole” of diverse shapes and sizes, resembling as closely as possible the user/patient's own defect which is virtually “cut” into the picture or video through software techniques, to be displayed to the lenses for the eyes to view.
  • this First Phase there is no video or image display, except what the user might see with the naked eye and with the existing defect.
  • the Second Phase FMT is the augmented reality video display which contains the Pixel Mapping, Interpolation, and Synthesis. This is the area where the pixels which have been "cut out” of the video or image are repositioned to the nearest adjacent area of the eye. These pixels and subpixels are repositioned on the area directly around the defective area of the eye, and the brain, like the case of the punctum caecum fills in the "hole" with the visual information added to the surrounding area.
  • the image is displayed directly onto the eyes through techniques like retinal projection.
  • the display is directly on the eye by virtue of Smart Contact Lenses, which can create a display on a contact lens covering the eye.
  • This pixel mapping and replacement occurs after the camera has acquired the image or video and the buffering begins.
  • This manipulation typically takes place in the Central Processing Unit (CPU) of a micro circuit; and more specifically in the Graphics Processing Unit (GPU) occasionally called the Visual Processing Unit (VPU).
  • CPU Central Processing Unit
  • GPU Graphics Processing Unit
  • VPU Visual Processing Unit
  • These GPU “chips” are specialized electronic circuits designed to rapidly manipulate and compress/decompress video and alter memory to accelerate the creation of images in a frame buffer intended for output to a display device. Speed is key here, as any latency will be evident in the display to the eye.
  • most of the modern GPU's can be configured to have only a 1 millisecond delay, between acquisition of the image or video, manipulation of the pixels and the display of the video, which the eye can easily accommodate and absorb in the display with little or no affect.
  • both the CPU and the GPU may need to be used and functions separated and an ASIC, which is an Application Specific Integrated Circuit, may be used to help combine the necessary CPU and GPU functions.
  • the CPU and the GPU work together, however, to accomplish the task and may need other parts on a circuit or circuit board to fully perform, such as capacitors, resistors, input/output connectors, circuitry, and the like.
  • two pixels or parts of an image which were originally exactly adjacent to one another on any axis up/down, sideways, or transverse may be moved together one way, or, if one pixel or part of an image is closer to one border than to the other, the pixels may be split with one pixel or image going to its closest border and the other pixel going to its closest border which is the essence of corrective subpixel mapping and modification.
  • the cutting of the "hole” and repositioning of the video or image may be accomplished primarily by stretching the pixels to a larger overall area than the original captured image (i.e. 100° stretches to 120° overall space, but the center 10° is cut out). In this method all the pixels are still there, in relatively the same size and shape, as originally captured and buffered by the camera(s), except either the far edge boundary has been extended or cropped. This method works well with Virtual Reality goggles, but not as well with Mixed Reality improvements in the technique. Thus, the preferred method in Mixed Reality Corrective Glasses (MRCG) is to use Pixel Mapping, Interpolation, and Synthesis (PMIS).
  • MMRG Mixed Reality Corrective Glasses
  • the pixels in the area of the display to be avoided are mapped, in real or near real time, within or without a buffer, and software algorithms keep the same shape of the image, but reduce the size of the pixels to subpixels, such an image which was, for instance, shown on four pixels, is now shown on three, two, or just one.
  • the resulting display has all the visual information, just displayed using a fewer number of pixels and subpixels.
  • pixels have been reduced to subpixels, which have been moved in the video according to the software implementation and the shape of the defect.
  • the pixels and the image that are moved do not necessarily have to have a specific "boundary" like an oval or a circle, but the pixels can be removed from any defect area, no matter how irregular and repositioned to a sighted area just adjacent.
  • the idea is not just one where boundaries are created, but where the image or video pixels are moved one by one out of the non-seeing, defect area to another location as close to that unsighted area as possible with the remaining image being likewise transposed to make room for the removed and replaced pixels and image.
  • the area to be avoided may be very irregular and complex, which makes no difference, as once it is mapped, pixels are removed from the space where no sight is and placed as closely adjacent to the place on the pixel map as possible, which is described herein as subpixel mapping and placement.
  • Pixels as used herein are perceived spaces where subpixel mapping is a recently developed technology involving algorithms to obtain and map the spatial distribution information of area covered within mixed pixels and then reposition them on a smaller or different scale. See, Figure 25. Algorithms can be applied to pixel mapped video or image content, and images moved from one location in the video to another wherein the shape may not be a homogenous shape like a circle or oval. In some instances, the pixels or subpixels must be "distorted” in order to have 100% of the image included into 100% of the display space. In this case the pixels or image take on a shape which is not a typical pixel square, but can be something besides a square, and often more like a tetrahedron or polyhedron, or shapes like triangles or parallelograms.
  • the classification on a per pixel basis is established and then reconstituted in a pixel/subpixel format to achieve subpixel mapping for modification.
  • an image or video can be displayed with augmented pixel/subpixel manipulation and stitching so that a whole image exists, just not in the original place as the camera input originally assigned.
  • the Third Phase where video is faded back into reality video through "stitching" or similar techniques which are used to merge combine the Second Phase with the Third Phase in steps where the Second Phase is "phased out” and the Third Phase of real world captured video dominates.
  • direct camera input is a phased-in re-engagement of the real world projected image.
  • the Second Phase Image Manipulation Technique merges with the Third Image Manipulation Technique to phase out the 100% pixel manipulation.
  • This Third Phase works the other way to reintroduce the image or video back to 100%) of what the camera actually acquires as an image.
  • the video may still be manipulated so as to correct for line-of-sight (to correct for the what the eye sees versus the camera captured images) and to correct for the epipolar geometry effect of the eyes moving inward and outward/straight.
  • This Third Phase software/hardware stitching is akin to the techniques commonly utilized in 3D video stitching software. It is in Phase Three where the augmented video is then returned to an un-modified video of what the user would actually "see” if the cameras were projecting and displaying raw, unmodified video or images.
  • This "raw” video is proj ected or displayed on the retina, contacts or lenses of glasses where only a portion of the Field of Vision is used for Phases One through Three and the rest of the display area is reserved for Phase Four video, where it can be merged by the eye and brain with the real-world vision which is external to Phase Four.
  • Phase Four is where the user sees with his or her peripheral vision the real world and upon which either the sight through the lenses or beyond the lenses, no video is displayed.
  • This Phase also includes any extra peripheral vision that is extant outside of the glasses, lenses, contacts, or retinal projection, and provides the user with additional real -world ques and images.
  • a user experiences four distinct image sets, all of which merge through the brain's natural simulations to create one Mixed Reality view of the world, which is corrected for the defect.
  • an augmented video which could be as large as 30-50 degrees Field of Vision or more. This could be greater or smaller depending on the type of defect and the amount of correction.
  • augmented video display on the lens is displayed a video of what the eyes would ordinarily see, but augmented in a phase-in/phase-out of the augmented video.
  • an implanted lens, or lenses, akin to an implanted intraocular lens performs some or all of the pixel manipulation by diverting pixels away from the damaged areas of the macula.
  • IOLVIP Intraocular Lens for Visually Impaired Patients
  • the IOLVIP procedure involves the surgical implantation of a pair of lenses that magnify and divert the image using the principals of the Galilean telescope. By arranging the lenses, it is possible to direct the image to a different part of the eye than the fovea.
  • the glasses, frame and headgear (GFH) and external display would be calculated to coordinate with the implanted lenses to cut out the image ordinarily displayed where the defect exists and project the full image on the display, which is then diverted by the implanted lenses and becomes a full image.
  • GSH headgear
  • this invention comprises a system having a database, a CPU, a model controller, a camera intake, a display controller, and a display unit.
  • the model controller which may be hardware, firmware, software, memory, microcontroller, state machine, or a combination of any of the forgoing, is coupled to the database and is configured to establish a reference to a visual model associated with a patient's visual defect; then the camera(s), one or more, take a picture or video of the actual image and the software makes corrections for the patient's visual defect and then the corrected/modified image is displayed which has been corrected for the patient's visual defect.
  • one or more cameras and lenses are enabled to assist the patient in identifying one or more of his or her visual impairment boundaries, and then transferring this information into the Visual Modification Program which augments the displayed video to displace video and picture images to displace the part of the image within the vision impaired boundaries and replace it to the nearest sighted area.
  • the Visual Modification Program also re-introduces real world images captured by a Camera Input System (CIS) so that an augmented video segment is displayed on the lenses, wherein the augmented video segment is phased back to a real -world, un-modified video, so that the "edges" of the displayed system are in sync or near sync with the real-world vision seen by the eyes.
  • CIS Camera Input System
  • the invention also includes a method to store the modified visual model in the database and to project it on a display.
  • the invention also includes a Diagnostic Impairment Mapping (DEVI) System and method to capture information about the area and location of the eye defect. An example of this would be mapping an area where macular degeneration has occurred and little or no sight or vision remains.
  • the corrected visual model includes data related to the quality of the patient's vision and the manipulation of images and/or pixels or other visual portions of a video or recorded image or images which correct for that patient's visual defect.
  • the corrected image is not a manipulation of pixels, but a mapping of pixels in software/firmware including a step of correction for the patient's visual defect through repositioning of the image onto other pixels or subset of pixels which are then projected onto the sighted areas of the eye, such that a whole picture or video is shown, but the portion of the eye that is defective is left with no image/video projection.
  • a mapping of pixels in software/firmware including a step of correction for the patient's visual defect through repositioning of the image onto other pixels or subset of pixels which are then projected onto the sighted areas of the eye, such that a whole picture or video is shown, but the portion of the eye that is defective is left with no image/video projection.

  • the Dynamic Opacity provides a "backdrop” or “background” display corresponding to the pixels where the virtual image is displayed making the contrast of the virtual display greater to the eye, so that brightness like natural sunlight can be minimized, which would otherwise compete with the reflected display and cause it to be hard to see.
  • the reflected display has a buffer between it and exterior light, which gives the reflected display greater brightness to the eye.

  • the whole foveal area including foveal pit, foveal slope, parafovea, and perifovea is considered the macula of the human eye. This is what is destroyed with macular degeneration.

This is a slightly larger area than the region that contains the yellow macular pigments, which is 4-6° in diameter ⁇ macula lutea) or the Macula.
  • the foveola approximately coincides with the area of peak cone density in the photoreceptor layer, and in general is centered within a small region devoid of retinal vessels - the ' foveal avascular zone' (FAZ).

  • an important aspect of this invention is to displace the pixels or image to as similar an area of the eye as possible, so that perception of the image by the eye is projected onto an area which is as close to the same as the damaged area, in terms of rods and cones, as possible.

  • the systems and methods create a distortion map of the entire image and project it onto the periphery of the eye, while avoiding the macula. This can be done by the use of computer aided 90-degree 3D or similar High Definition goggles or glasses, or by photon projection with a virtual retina display of the image directly onto the retina of the eye.
  • the method and manner of the skewed projection relies on external lenses, with up to 2 million pixels, a resolution seen only otherwise on ultra-high-definition TVs and tablet computers, which provide the resolution needed to put the entire image on the peripheral retina receptors in sufficient detail to be analyzed by the optical nerve and brain.
  • the goggles and/or glasses could be used to house a technology like virtual retina display, retina scan display projection, and/or a retinal projector technology which all use photon on retina projection, which in this case would be modulated by the IDM (Image Distortion Map) to the person's specific Retinal Map so that an intentionally distorted image would be projected onto the areas of the eye which have the best visual reception.

  • Another advantage is that these types of wide field-of-vision goggles or glasses can be used in conjunction with one or more cameras, which are typically head mounted.
  • Another advantage of these types of glasses is that they can be combined with proximity sensors, motion sensors, head and eye tracking, a feature which is advantageous for understanding a user's specific field of vision for adjustments, and to measure distance through tri angulation.
