Augmented Reality (AR) and Virtual Reality (VR) technologies are transforming digital interactions by redefining how users engage with virtual and physical environments. These technologies employ distinct approaches to create immersive experiences, with AR enhancing real-world environments through digital overlays while VR generates fully synthetic environments. The advancement in display technologies, tracking systems, and rendering capabilities has enabled practical applications across industries ranging from retail and manufacturing to healthcare and education. The integration of sophisticated hardware components with intuitive software frameworks has addressed key challenges in user comfort, environmental adaptation, and performance optimization. Development platforms like Unity and Unreal Engine provide robust foundations for creating and deploying these immersive experiences, while standardization efforts through APIs and platform-specific frameworks continue to streamline development processes.
