Immersion in VR (Virtual Reality) refers to the degree to which a user feels completely absorbed in a simulated environment created by a computer program. In other words, the user feels like they are actually present in the virtual world, and the experience feels real.
There are several factors that contribute to the feeling of immersion in VR. These include the quality of the graphics, the responsiveness of the virtual environment to the user’s movements, and the accuracy of the user’s interactions with the virtual world. Additionally, sound, haptic feedback, and other sensory inputs can also enhance the sense of immersion.
