Virtual reality and its social impact

Virtual retinal monitor

This sort of device projects a picture onto the retina of the eye. As a result, the picture seems to be "hanging" in mid-air in front of the user. Because pictures of virtual items that the user sees are superimposed on photos of real-world objects, these devices are closer to augmented reality systems. Devices of this sort can, however, be used to immerse the user in virtual reality under particular conditions (dark room, sufficiently wide retinal image coverage, as well as in combination with a tracking system).

There are also a variety of hybrid possibilities, such as the CastAR system, which achieves a proper projection of an image on a plane by mounting the projectors directly on the glasses, as well as stereoscopic separation by utilizing a reflective coating on the projection surface. However, such gadgets are now only available as prototypes and are not widely used.
The most advanced virtual reality systems at the present are projection systems set up in a virtual reality room configuration (CAVE). A room with a 3D stereo picture projected on all walls is an example of such a system. Tracking systems detect the user's location and head rotations, allowing you to obtain the greatest immersion effect. These systems are utilized for a variety of objectives, including marketing, military, scientific, and others.

Sound

The multichannel speaker system allows the user to localize the sound source, allowing them to traverse the virtual environment with their ears.
