The document discusses augmented reality (AR) and virtual reality (VR). AR enhances real-world environments with computer-generated information like visual, auditory, and haptic overlays. Examples include Pokémon Go and Google Maps with AR overlays. While AR can limit content selection and raise privacy issues, VR uses simulation to create near-realistic experiences different from reality, such as interactive games. Development and maintenance of AR applications and devices can also be costly with extensive training required.

2. Augmented Reality
Augmented reality (AR) is an interactive
experience of a real-world environment
where the objects that reside in the real
world are enhanced by computer-
generated perceptual information,
sometimes across multiple sensory
modalities, including visual, auditory,
haptic, somatosensory and olfactory.

4. Advantages and disadvantages of AR
• Using AR tends to limit reading selection to its own
books
• Using AR tends to limit reading selection to a narrow
band of readability
• Using AR tends to discriminate against small publishing
companies and less popular authors.
• One major drawback of AR based application is the lack
of privacy
• AR based applications or devices cannot be leveraged
without appropriate training thus increase costs and time
involved
• It can get extremely costly to develop and maintain an AR
based device or an application.

5. Virtual reality
Virtual reality (VR) is a simulated experience
that can be similar to or completely different from
the real world. The definition of virtual
reality comes, naturally, from the definitions for
both ‘virtual’ and ‘reality’. The definition of
‘virtual’ is near and reality is what we experience
as human beings. So the term ‘virtual reality’
basically means ‘near-reality’. This could, of
course, mean anything but it usually refers to a
specific type of reality emulation.
