Virtual, augmented, and mixed reality technologies provide immersive digital experiences by overlaying images on a user's view of the real world. Virtual reality uses headsets to completely replace visual perception of the real world, while augmented reality enhances the real world with digital content. Mixed reality fuses elements of real and virtual worlds together. These technologies have applications in healthcare like medical training, education like virtual classrooms, and the military for simulation training. As the technologies advance, they have the potential to revolutionize many industries by improving productivity, work processes, and learning.
