Which of the statements given above is/are correct?
(a) 1 and 2 only
(b) 3 and 4 only
(c) 1, 2 and 3 only
(d) 4 only

Answer: B

• Statements 1 and 2 are not correct: Augmented reality (AR) is the superimposition of computer-generated images on existing environments to make them more interactive. It is utilized in the form of applications for mobile devices.
• Virtual reality (VR) is a computer-generated simulation of real-life environments that is primarily achieved with the use of headsets. When worn, the user’s vision and hearing are stimulated to provide realistic experiences.
• Statements 3 and 4 are correct: VR completely puts the user in a simulated reality, AR blends the virtual and real. Like VR, an AR experience involves some sort of goggles through which we can view a physical reality whose elements are augmented (or supplemented) by computer-generated sensory input such as sound, video, graphics, or GPS data.
