Samsung is serious about making a breakthrough in the field of virtual and augmented reality — the company has invested in AR/XR glasses with vision correction and autofocus.
The tech giant has filed patents for XR smart glasses and metal lenses. Both technologies create lightweight glasses that are especially important for visually impaired people who face discomfort when using headsets.
But let’s talk about Samsung’s developments Smart glasses XR are equipped with automatic vision correction, which allows you to get a comfortable and clear picture. The mechanism is based on gears and drives that adjust the position of the lenses, change the focus and field of view of the headset display. The device automatically adjusts the image to the user’s vision. The built-in display is also dynamically adjusted to better align the natural field of view (i.e., when looking without moving the head or eyes).
Carl Zeiss AG, Sunny Optical Technology, and Goertek Inc. have already tried to implement similar technology. All three companies had the same problem — the glasses were not comfortable for the user, namely because of the lenses that required manual adjustment. At one time, Goertek’s lenses had problems adapting to the individual needs of users. So far, Samsung’s «on paper» approach seems to be more technologically advanced and comfortable.
The second advanced technology is called metalens. Ultralight lenses are expected to provide high image quality without color distortion due to their nanostructures. They are used to manipulate/control the direction of light at the nanoscale. But it’s not that simple. The very technology of metalens has been plagued with serious problems, such as chromatic aberration
this is an optical distortion that occurs because different wavelengths of light (colors) are focused at different points after passing through a lens. This results in an image with colored borders or blurring at the edges of objects. that caused color distortion.
In the scientific journal Nature Materials an article from Samsung and Pohang University of Science and Technology (POSTECH) appeared. In it, the authors explained the mechanics of the metalens and said that they were able to eliminate the color distortion disadvantage due to the interconnections between individual metastructures. This approach can not only achieve more precise light control and reduce the weight of XR devices, but also improve the quality of holographic displays.
It’s hard to say at this point whether Samsung will use metalens technology in it’s the first XR headset, known as Project Moohan. The device is in development, but not all of the patented technologies will make it into the final product. But it’s clear now: the company is making a serious bid for the future of virtual and augmented reality.
