The technology that allows users to experience a virtual representation of a physical space is known as Virtual Reality (VR) or Augmented Reality (AR). VR immerses users in a computer-generated environment, while AR overlays digital information onto the real world. Both technologies utilize advanced hardware, such as headsets and sensors, to create engaging experiences. These applications can range from gaming and entertainment to training simulations and architectural visualization, enabling users to interact with 3D models and environments in innovative ways.
