Today, we spend much of our time using screens, like computers, smartphones, and televisions, which play a central role in how we get news, use social media, and watch movies. Virtual Reality (VR) and Augmented Reality (AR) are two technologies revolutionizing screen use by creating interactive experiences. VR uses a headset with a built-in screen to transport users to virtual environments, with head tracking allowing them to look around by moving their head. AR, on the other hand, overlays digital images onto the real world through devices like smartphones or clear visors. While VR immerses users in a virtual world, AR enhances the real world with digital elements.
