Virtual Reality can create an impact that lasts even after the experience has ended. The viewer is instantaneously transported to new real or imagined places. Putting on a head-mounted display (HMD) removes all distractions and therefore directs full attention to the subject matter. Total focus and a feeling of being there (“presence”) elicits a strong emotional response from the viewer and stimulates memory formation. For that reason VR experiences are often used to evoke empathy or as a highly effective training tool.
