(a) Explain the difference between augmented reality (AR) and virtual reality (VR). [2]
(b) Give one example of how AR could be used in education. [1]
(c) Give one example of how VR could be used in healthcare. [1]
(d) State one advantage and one disadvantage of using VR for training purposes. [2]
(e) State one piece of hardware needed for VR. [1]
Answer Details
(a) Augmented reality (AR) overlays digital content such as images, text and graphics onto the user's view of the real world, enhancing what they can already see. [1] Virtual reality (VR), by contrast, creates a completely immersive, computer-generated environment that entirely replaces the real world around the user. [1]
(b) An example of AR in education: a student could use a tablet to point at a textbook page and see a 3D model of a human heart appear on screen, allowing them to explore its structure interactively. [1]
(c) An example of VR in healthcare: surgeons could practise complex operations in a simulated virtual environment before performing them on real patients, reducing the risk of errors. [1]
(d)
- Advantage: VR allows people to practise dangerous or expensive procedures (such as flight simulation or surgery) in a safe, risk-free environment that can be repeated as many times as needed. [1]
- Disadvantage: VR equipment can be expensive to purchase and maintain, and some users may experience motion sickness or discomfort during prolonged use. [1]
(e) One piece of hardware needed for VR is a VR headset (also called VR goggles), which displays the virtual environment and tracks the user's head movements. [1]
