In cinemas we can still watch movies in 3D (and in this release it makes some sense, although some users still complain of headaches and discomfort caused by heavy glasses), but a similar trend in the case of home TVs disappeared sooner than it appeared. For a while, TV producers actually explored its possibilities, but customers ultimately did not show much interest, especially since the effects were not as good as in the cinema, so the subject died a natural death. It seems, however, that not for everyone, because Sony has just presented its 15.6-inch Spatial Reality Display panel with a 4K resolution, which offers eye tracking and the ability to watch 3D materials without the need to use VR glasses or goggles.
All this for only ... 5,000 dollars - the price seems to be an exorbitant price, but it is worth adding that Sony directs its device to professionals in the field of design, 3D art or other similar industries, who still spend much more on work tools than the average consumer. The target is probably that also because the display allows only one person to view 3D images, which practically excludes purely entertainment use. The whole thing resembles a classic computer monitor, but the panel is inclined at an angle of 45 °, and it is equipped with a camera for tracking movement and a layer of micro-optical lenses.
How does it all work? The camera tracks the eye movement and the position of the user's head to match the displayed content to the natural viewing of objects around us. The aforementioned lenses divide the displayed image into the right and left eye, enabling stereoscopic vision, i.e. representing world top technology only the shape and color of objects, but also their mutual spatial relations, distance from the observer and the depth of the scene. Sony assures that a special algorithm provides real-time processing, so that "3D images look as smooth as the real thing, even if we move." Is it really so? Sean Hollister from The Verge, who has already had a chance to see this product, has some doubts about it. In his opinion, although everything looks impressive at first, the 3D illusion is very easy to destroy: - You are looking at a virtual diorama, at my eye measuring 13 by 6-5 inches, and any virtual object deeper or taller than this will be cut off by the edges of the display. If you lean too far or too close, the camera will not be able to track you and the 3D effect may break or disappear, he explains. Nevertheless, if you are interested in buying it, Sony will open sales to everyone in November.
