VR stands for Virtual Reality, a technology that immerses users in a completely digital environment, often using headset devices. In contrast, AR, or Augmented Reality, overlays digital information onto the real world, enhancing the user's actual surroundings with digital content. VR requires complete immersion, which can require a significant amount of hardware, whereas AR can be experienced through smartphones and tablets, allowing for interaction with both real and virtual elements. Both technologies have distinct applications such as gaming, education, and training, offering unique experiences based on their differing methodologies.
