This presentation about the Augmented Reality : Augmented reality (AR) is a real-time experience that combines the real world with computer-generated content. This content can include visual, auditory, haptic, somatosensory, and olfactory elements. Augmented reality is an interactive experience that enhances the real world with computer-generated perceptual information. Using software, apps, and hardware such as AR glasses, augmented reality overlays digital content onto real-life environments and objects. Types of Augmented Reality:- 1. Marker-based AR 2. Markerless AR 3. Projection-based AR 4. Superimposition-based AR 5. Location-based AR

What is Augmented
Reality (AR)?
"Augmented reality (AR) is a real-time
experience that combines the real
world with computer-generated
content. This content can include visual,
auditory, haptic, somatosensory, and
olfactory elements. "

3. Augmented Reality
(AR) Example

What is Augmented
Reality (AR)?
"Examples of AR in everyday life include
Snapchat filters, Pokémon Go, and
Ikea's AR app "

Types of Augmented
Reality (AR)?
There are five types of Augmented Reality
2. Markerless
AR
4. Superimposition-
based AR
1. Marker-
based AR
3. Projection-
based AR
5. Location-based
AR

5. 1. Marker-based AR
"Maker-based AR works by scanning a
marker which triggers an augmented
experience (whether an object, text,
video or animation) to appear on the
device. It usually requires software in the
form of an app, which enables users to
scan markers from their device using its
camera feed."

6. 1. Marker-based AR
Example
"A series of QR codes that participants
scan to learn more information about the
location they are touring"

Reality (AR)?

7. 2. Markerless AR
"Markerless Augmented Reality is used to
denote an AR application that doesn’t
need prior knowledge of a user’s
environment to overlay 3D content into a
scene and hold it to a fixed point in
space."

Reality (AR)?

8. 2. Markerless AR
Example
"Pokemon Go: Put a Pokemon in your
device's live camera view."

9. 3. Projection-based
AR
"Projection-based AR (PBAR) is a type of
augmented reality (AR) that uses a fixed
projector to overlay 3D objects onto the
real world. It's also known as Spatial
Augmented Reality (SAR) or Projection
Mapping. "

Reality (AR)?

10. 3. Projection-based AR
Example
"Projectors can create the illusion of
moving textures, animations, and 3D
effects on the intricate architectural
details of a building."

Types of Augmented
Reality (AR)?

11. 4. Superimposition-
based AR
" Superimposition-based augmented
reality (AR) is a technique that uses object
recognition to replace an original image
with an augmented view. The augmented
image can replace the original image
partially or fully."

Types of Augmented
Reality (AR)?

12. 4. Superimposition-
based AR Example
“Image filters on social media that replace
your face or background with an
enhanced image run on superimposition-
based AR."

Reality (AR)?

13. 5. Location-based AR
"Location-based Augmented Reality
refers to the integration of digital
information, such as 3D models, text, and
other interactive elements, into the
physical world using a device such as a
smartphone, tablet, or a head-worn
device."

Reality (AR)?

14. 5. Locagtion based AR
"Examples of Augmented Reality Apps
Available on the Market
1. Google Maps Live View.
2. Wikitude World Browser - another
example of location-based AR.
3. Sky Guide."
