Questions 21-23 (Suggested completion time: 7 minutes) Directions: Read the text about virtual reality and augmented reality, and answer the questions according to the information in the text. Virtual Reality vs. Augmented Reality One of the biggest confusions in the world of augmented reality is the difference between augmented reality and virtual reality. Both are earning a lot of media attention and are promising tremendous growth. Virtual reality (VR) is an artificial, computer-generated simulation or recreation of a real-life environment or situation. It immerses the user by making them feel they are experiencing the simulated reality firsthand, primarily by stimulating their vision and hearing. Augmented reality (AR) is a technology that layers computer-generated enhancements atop an existing reality in order to make it more meaningful through the ability to interact with it. AR is developed into apps and used on mobile devices to blend digital components into the real world in such a way that they enhance one another, but can also be told apart easily. Augmented reality and virtual reality are similar in that both are inverse reflections of one in another with what each technology seeks to accomplish and deliver for the user. Virtual reality offers a digital recreation of a real-life setting, while augmented reality delivers virtual elements as an overlay to the real world. Both leverage some of the same types of technology, and they each exist to serve the user with an enhanced or enriched experience. However, the two also differ from each other in various ways. Augmented reality enhances experiences by adding virtual components such as digital images, graphics, or sensations as a new layer of interaction with the real world. It is being used more and more in mobile devices such as laptops, smart phones, and tablets to change how the real world and digital images, graphics intersect and interact. Contrastingly, virtual reality creates its own reality that is completely computer generated and driven. It is usually delivered to the user through a head-mounted or hand-held controller. This equipment connects people to the virtual reality, and allows them to control and navigate their actions in an environment meant to simulate the real world. 21-23.
