A new type of display will help prevent eye fatigue when using virtual reality glasses
The success of many head-mounted display contributes more to the mass development of this technology. But despite any incomparable thrill of the new technology, there she and some disadvantages. For example, long "stay" in a virtual environment leads to fatigue and severe fatigue of eyes. Solution would be a new development of scientists from the University of Illinois, who presented a prototype three-dimensional display, the image is perceived in the same way as the image of the surrounding world.
The new display, or rather its working prototype, has a size of 2, 5 by 5 centimeters. He is able to reproduce a realistic image due to a number of interesting innovations. The fact is that usually a three-dimensional image in the head-mounted display is obtained by the technology of so-called optical imaging - Optical Mapping. Its essence lies in the fact that the optical display, the screen is split into several areas, each area formed by its two-dimensional image.
After that, each two-dimensional region "gets" the depth and special algorithms ensure transitions depth so that the result is one continuous three-dimensional image. The main element of the process of the new system is a spatial multiplexing device which "pushes" parts of the image area to a predetermined depth. The device consists of a spatial light modulators that alter the light passing through them by a certain algorithm, allowing the brain to "cheat." The most interesting is that the new technology can work with any type of existing displays.
"In the future we plan to replace the spatial light modulators other optical components, such as elements of volume holography. These components not only will reduce the size and weight of the device. They also consume much less energy. "
