Virtual reality and its social impact

Virtual reality helmet

Modern virtual reality helmets (HMD-displays) are glasses rather than a helmet, and contain one or more displays that display images for the left and right eyes, a lens system for correcting the geometry of the image, and a tracking system that tracks orientation devices in space. As a rule, tracking systems for virtual reality helmets are developed based on gyroscopes, accelerometers and magnetometers. For systems of this type, a wide viewing angle is important, the accuracy of the tracking system when tracking tilts and turns of the user's head, as well as a minimum delay between detecting a change in the position of the head in space and displaying the corresponding image on the displays.
