Abstract: Over the past few decades, augmented reality (AR) and virtual reality (VR) have experienced a significant surge in popularity and adoption. However, the precise distinctions and defining characteristics of these technologies are often not well understood or discussed. This paper seeks to delve deeper into the nature of AR and VR, shedding light on their fundamental principles and workings.

To begin with, augmented reality (AR) refers to a technology that overlays digital content onto the real world, enhancing the user's perception and interaction with their surroundings. By utilizing various sensors, such as cameras and motion trackers, AR systems gather real-time information from the environment and merge it with computer-generated elements. This seamless blending of virtual and real elements allows users to see and interact with digital objects in their physical environment. Examples of AR applications range from simple smartphone filters and games to more advanced industrial and medical training simulations.

On the other hand, virtual reality (VR) creates an entirely immersive digital environment that transports users to a simulated reality. By wearing a VR headset, users are visually cut off from the real world and are instead presented with a computer-generated 3D environment. VR systems typically employ headsets with built-in displays and motion-tracking capabilities to accurately replicate the user's movements within the virtual space. This immersive experience can be enhanced further with additional sensory feedback, such as haptic feedback gloves or spatial audio systems. VR finds applications in gaming, education, architecture, and even therapy, providing users with a compelling sense of presence and interaction within the virtual realm.
