Virtual Reality (VR)

Virtual Reality places you inside a computer-generated environment. A VR headset replaces your view of the physical world and tracks your movements, so the simulated world responds as if you were really there. These systems support immersive games, training, design and social spaces.

Augmented Reality (AR)

Augmented Reality layers digital information and imagery onto the real world. AR Glasses can present digital content alongside the physical world. The broader smart-glasses category also includes camera and audio devices without a display. Mixed reality systems can connect virtual content with the surrounding space.
