There virtual reality it is a technological frontier increasingly present in our world, but for its greater diffusion a fundamental role is played by eyeglassesnecessary interface and often main obstacle to the enjoyment of a truly immersive experience – just look at the Meta Cambria renderings to realize it. In fact, up to now, virtual reality viewers still have evident limitations due to excessive bulk and heaviness. Nvidia seems to have found a way to overcome this inconvenience. She did so by carrying out extensive research conducted together with Stanford University.
THE SECRET IN THE HOLOGRAPHIC IMAGE
The excessive size of current VR systems is due to the need to adequately space the lens that magnifies the holographic image from the display. This is to present a sufficiently wide vision to the eye. The solution developed by Nvidia and Stanford University foresees a holographic display near each eye capable of presenting a 2- or 3-dimensional image, all with a depth of just 2.5mm. The result is achieved with a technology called “spatial light modulator”, capable of create the holographic image right in front of the eye.
The image quality is guaranteed by the intervention of artificial intelligence and also the design and shape of the displays are defined by a particular algorithm, capable of identifying the best solutions.
NEW FRONTIERS ON THE HORIZON
The research was also accompanied by a short video of a prototype and you immediately notice how significant the step forward is. All the device has overall dimensions and dimensions similar to a normal pair of glasses.
The potential is evident: being able to insert a virtual reality device into an object the size of a pair of glasses will open the door to a widespread use of this technology, with almost infinite practical – and certainly interesting – implications in everyday life.
