Virtual & augmented reality (VR/AR) software provides the tools and platforms necessary to create immersive digital experiences that either supplement or replace our perception of the real world. VR software is used to build fully-enclosed, simulated environments, transporting users to entirely new digital realms, often experienced through a headset. This is used extensively in gaming, training simulations (like for surgeons or pilots), and virtual architectural walkthroughs. In contrast, augmented reality software is designed to overlay digital information—such as images, text, and 3D models—onto the user's real-world view, typically via a smartphone or smart glasses. Common examples include interactive social media filters, apps that let you see how furniture would look in your room before buying it, and heads-up displays for manufacturing or maintenance workers. This category of software is at the forefront of creating the next generation of human-computer interaction.
