Virtual reality uses headsets with built-in displays and sensors to create stereoscopic 3D environments that respond to the user's head movements, allowing them to look around. Additional devices like controllers can provide haptic feedback and enable interaction. This transports users to new virtual places and opens educational possibilities in physical sciences by simulating sights, sounds, and touch. Popular game engines like Unity, Unreal Engine, and Godot support virtual reality development and provide tools for creating immersive VR experiences across multiple platforms.
