Augmented reality is an interactive experience of a real-world environment in which real-world objects are augmented by computer-generated perceptual information. It can include visual, auditory, haptic, somatosensory, and olfactory perceptual modalities. It is a combination of real and virtual worlds, a dynamic interaction in real time.
Virtual reality is the use of computer technology to create simulated environments. Instead of seeing the screen in front of them, users are immersed in the virtual world and can interact with it. In the virtual reality world, the user’s senses are stimulated, such as sight, hearing, touch, and even smell.
Mixed reality is exactly what the word implies: a blend of physical and digital worlds that enables interaction between humans, computers and the environment. This new reality is based on advances in computer vision, graphics processing power, display technology and input systems. In mixed reality, the computer is quite aware of the space the user is in and there are active interactions between the virtual and real worlds.
