3. Glossary

• Virtual reality (VR) is an interactive computer-generated experience
taking place within a simulated environment.
• Augmented reality (AR) is an interactive experience of a real-world
environment where the objects that reside in the real-world are
"augmented" by computer-generated perceptual information.
• Universal Windows Platform (UWP) is an open source API created by
Microsoft and first introduced in Windows 10. The purpose of this
platform is to help develop universal apps that run on Windows 10,
Windows 10 Mobile, Xbox One and HoloLens without the need to be
re-written for each.
• The field of view (FoV) is the extent of the observable world that is
seen at any given moment.

• In 1994 Paul Milgram and Fumio Kishino defined a mixed reality as
"...anywhere between the extrema of the virtuality continuum" (VC)[1]
• It was applied to displays. Since then, the application of mixed reality goes
beyond displays but also includes environmental input, spatial sound, and
location.

7. Technology in Brief

• In a nutshell, MR allows the viewer to see virtual objects that appear
real, accurately mapped into the real world.
• This particular subset of the “reality” technologies has the potential
to truly blur the boundaries between what we are, what everything
else is, and what we need to know about it all[2].

13. Holograms

https://docs.microsoft.com/en-us/windows/mixed-reality/hologram
Holograms
HoloLens lets you create holograms, objects made of light and sound
that appear in the world around you, just as if they were real objects.
