System, method, and non-transitory computer-readable storage media related to correction of vision defects using a visual display
Techniques related to vision correction are disclosed. The techniques involve establishing a visual model associated with a patient. The visual model includes data related to a quality of the patient's vision. A boundary is established as a function of the data associated with the visual model. The boundary is indicative of an area to be corrected within the patient's vision. A retinal map is established as a function of the boundary. An image from a camera associated with the patient is captured and corrections are applied to the image based on the retinal map to generate a corrected image. The corrected image is presented to the eye of the patient.
1. A system comprising:
goggles or glasses housing technology capable of photon-on-retina projection;
a display controller configured:
to receive and to store a retinal map associated with a user identifying the user's usable field of vision, the retinal map including at least one boundary indicating an area to be modified within the patient's vision;
to receive an image from a camera associated with the user;
to generate an image distortion map including shifting image data located within the boundary outwardly along a plurality of rays starting at an estimated center point of the area to be modified within the patient's vision to outside the boundary such that the image data from the center point to an edge of the image is compressed from the boundary to the edge of the image; and
to modulate the image based on the image distortion map to produce an intentionally distorted image, where the technology capable of photon-on-retina projection is capable of projecting the intentionally distorted image onto the user's retina in the user's usable field of vision.
2. The system of claim 1 where the technology capable of photon-on-retina projection is a virtual retinal display, a retinal scan display, or a retinal projector.
3. The system of claim 1 where the camera is head mounted.
4. The system of claim 1 , the system further comprising:
proximity sensors;
motion sensors; and
head and eye tracking, such that the system is capable of tracking head movement and eye gaze to correspondingly change the angle of projection to the retina to gain visual acuity.
5. The system of claim 4 , the system further comprising two cameras to simulate stereoscopic vision, wherein the image distortion map includes factor correction for epipolar curves, guided by epipolar geometry so that stereo vision is employed, displayed, and seen.
