Augmented reality (AR) combines real and virtual objects in real time. AR enhances natural environments with overlays of supplemental information. This document discusses AR definitions, technologies like head-mounted displays and handheld devices, software techniques like SLAM, and applications in various fields like education, gaming, tourism and more. Examples provided include using AR for architectural design, medical training, and GPS navigation. Both opportunities and challenges of AR are addressed.

Understand what geospatial technology is? Geospatial technology refers to all the techniques used to acquire, manipulate & store geographic information. Geospatial Technology is one of the forms of GIS. Various tools accomplish it like GIS, GNSS, RS, & other emerging technologies like Artificial Intelligence, IOT, Augmented Reality (AR), etc

Whereas virtual reality replaces what people see and experience, augmented reality actually adds to it. Using devices such as HTC Vive, Oculus Rift, and Google Cardboard, VR covers and replaces users' field of vision entirely, while AR projects images in front of them in a fixed area.
Virtual Reality and Augmented Reality are two types of modern technologies that are gradually and increasingly being used in our life. Hence, it is important that we understand what they are about and the difference between the two.
Augmented reality (AR) is a technology which provides real time integration of digital content with the
information available in real world. Augmented reality enables direct access to implicit information
attached with context in real time. Augmented reality enhances our perception of real world by enriching
what we see, feel, and hear in the real environment. This paper gives comparative study of various
augmented reality software development kits (SDK’s) available to create augmented reality apps. The
paper describes how augmented reality is different from virtual reality; working of augmented reality
system and different types of tracking used in AR.

Augmented reality The future of computingAbhishek Abhi
This is a PPT on Developing Augmented Reality this field is rapidly developing around the world. this ppt describes the entire meaning of the word augmented reality and what it is made up off and the working of this devices.
Augmented reality (AR) is a live direct or indirect view of a physical, real-world environment whose elements are "augmented" by computer-generated or extracted real-world sensory input such as sound, video, graphics, haptics or GPS data.[1] It is related to a more general concept called computer-mediated reality, in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. Augmented reality enhances one’s current perception of reality, whereas in contrast, virtual reality replaces the real world with a simulated one.
presentation for augmented reality. ,It consists of introduction, working, components of AR, applications, limitations, recent development and conclusion. all the best for your presentation

Visual computation in virtual reality
Augmented Reality
Application of VR
Augmented reality is a type of virtual reality that aims to duplicate the world’s environment in a computer. An augmented reality system generates a composite view for the user that is the combination of the real scene viewed by the user and a virtual scene generated by the computer.
6. AUGMENTATION
This is a kind of enhancing an object
Reality
The state of things as they actually exist.
Augmented reality = Real world + Virtual world
7. Thus augmented reality is
A live direct or indirect view of a
physical, real-world environment
whose elements are augmented by
computer-generated sensory input
such as sound, video, graphics or
GPS data.
8. WHY AUGMENTED REALITY?
Combines real and virtual object in a real environment.
Runs interactively and in real time.
It is to augment the real world with information handling capabilities.
It superimposes graphics over a real world environment in real time.
9. Overview of the technology
Components:
o Scene Generator
o Tracking System
o Display
o Control
o Data
10. Head Mounted Display
User can simultaneously
view both the real world
and virtual world.
Can be a bit bulky in its
current form
11. Handheld
Devices Most commonly used AR Devices
Uses a variety of Sensors
AR Toolkit is usually used to
map the real world
12. Software Based AR
Use multiple sensors and tracking devices like GPS, Compasses
etc…
Are leading the innovation in AR now.
Two Stages Detection of Interest Points, Mapping the two
worlds.
14. Software and Technique
AR systems realistically integrate augmentations with the
real world by a process called image registration.
First detection of interest points.
Second is restoration of a real world coordinate system
from the data obtained in the first stage [SLAM].
15. Simultaneous Localization And Mapping
SLAM is a technique to build up a map within a known or
an unknown environment while at the same time keeping
track of the current location.
Maps are used to determine a location in an environment
and to depict this environment for an overview.
16. How does SLAM work
Takes input
Builds map
using GPS
Locating and
mapping
process repeats
in a loop
20. MEDICAL
• AR can provide the surgeon with
information, which are otherwise
hidden, such as showing the
heartbeat rate, the blood
pressure, the state of the patient’s
organ, etc.
• Also, patients wearing Google
Glass can be reminded to take
medications.
21. Digital Compass
• A digital compass consists of
sensors to measure the earth’s
magnetic field, some conditioning
of those sensor signals, and a
microcontroller to interpret the
data.
22.
23. EDUCATION
AR can be used to have a deeper understanding
about science, biology, etc. E.g. chemical
bonding in molecules or functioning of heart
through AR could give students a much clearer
picture about the process.
26. ASTRONOMICAL REASEARCH
Star Walk is a star gazers
ultimate app for
finding celestial bodies in
real-time using
augmented reality.
27. Weather Forecast
This is implemented in
Augmented Reality by the
process known as
CHROMA-KEYING.
28. Other Applications of AR
• Military and defense system
• Sports and entertainment
• Sightseeing or Tourism
• Disaster Management
• And Supports many complex tasks….
29. Augmented Reality Today
• AR enhances a user’s perception of
interaction with the real world.
• The virtual objects displays information
that the user can’t directly detect with
his own senses.
• The information conveyed by the virtual
objects helps a user perform real world
tasks.
Motivation:
35. GLOBAL POSITIONING SYSTEM
A navigational system involving satellite and
computer that can determine the latitude and
the longitude of the receiver on earth by
computing the time difference of the signal
from different satellite to reach the receiver.
37. Blurs the line between what's real and what's computer-
generated.
Information about the surrounding real world becomes
interactive and digitally manipulable.
Reality with more information added to it that is
normally not available.
38. Expensive to develop and maintain
Lack of Privacy
In case of GPS, we can not view the vehicles who are
passing by as it is dynamic in nature.
