Augmented reality (AR) and virtual reality (VR) differ primarily in user experience and immersion levels. AR overlays digital information onto the real world, allowing users to interact with both physical elements and digital enhancements via devices like smartphones or smart glasses. Conversely, VR provides an immersive experience by completely substituting the real world with a virtual environment, typically using headsets. While AR enhances reality, VR creates a fully simulated experience, making them suitable for different applications, such as gaming, education, and training, tailored to the specific needs of users and contexts.
