These are answers for intro to ar/vr/mr/xr technologies week 1

1. What is a key characteristic of virtual reality (VR)?

• VR superimposes virtual content onto the real-world view

• VR replaces the real-world view with computer-generated content

• VR enhances the real-world view with virtual overlays

2. What are the three (3) key characteristics of augmented reality (AR)?

• AR shows you a completely different world around you

• AR makes virtual objects interactive in real-time

• AR replaces the physical world with a fully virtual environment

• AR makes virtual objects appear as if they were part of the real world

• AR combines real and virtual objects to produce a composite view

3. What are key differences between virtual reality (VR) and augmented reality (AR)?

• AR enhances reality whereas VR replaces reality

• VR is essentially a computer-generated, synthetic world whereas AR merges the virtual world with the physical world

• The R in AR is not the same as the R in VR

• VR is more realistic than AR

4. What is mixed reality (MR)?

• MR is the spectrum of augmented reality and augmented virtuality combined

• MR is exactly the same as augmented reality

• MR is just another word for virtual reality

5. What is extended reality (XR)?

• XR is a superior version of mixed reality

• XR is an umbrella term to refer to the whole space of augmented, mixed, and virtual reality

• XR is the latest set of technologies superseding augmented, mixed, and virtual reality
