Vision

Vision

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Background:

Conventional retinal prostheses have limitations in mimicking natural human vision due to electrode spacing.
Developing advanced visual prosthetics is crucial for restoring sight to individuals with retinal degenerative diseases.

Purpose of the Study:

To introduce an implantable metaverse system incorporating novel retinal prostheses and bionic vision processing.
To enhance visual perception by optimizing electrode placement and developing advanced image processing algorithms.

Main Methods:

Developed retinal prostheses with rearranged electrodes to match ganglion cell distribution, unlike equidistant spacing.
Created a bionic vision processing scheme integrated with a three-dimensional eye model.
Implemented visualization of monocular images, binocular image fusion, and parallax-induced depth mapping.

Main Results:

The novel electrode arrangement offers a more biologically relevant interface for visual prostheses.
The bionic vision processing successfully generated realistic visual outputs, including depth perception.
Demonstrated the potential for a more immersive and functional visual experience through the implantable metaverse.

Conclusions:

The proposed implantable metaverse with optimized retinal prostheses and bionic vision processing represents a significant advancement in visual restoration technology.
This approach offers a pathway to more natural and intuitive artificial vision.
Further research can explore clinical applications and refine the system for widespread use.
