1 Introduction
This chapter consists of general introduction, current scenario and history of augmented reality. It also
identifies the major keywords used in the report.
1.1 General Introduction
AugmentedRealityisa termusedforinteractivecomputergraphicswhichoverlaysaviewof the physical
world. The trick isdone by capturingthe currentview witha camera, andinsertingcomputergenerated
contentinto the scene,so the user seesboththe real worldand the extracontent: an augmentedview
of reality. (McGrath, 2014)
AR allowsthe userto see the real world,withvirtual objectssuperimposeduponorcompositedwiththe
real world. Therefore,ARsupplementsreality,ratherthantotallyreplacingit. Ideally,itwouldappearto
the user that the virtual and real objects coexisted in the same space. (Azuma, 1997)
1.2 Current Scenario
Augmented Reality started to boom and came under lime light soon after the introduction to smart
phones. Marxent’s Visual Commerce is cross-platform SaaS (Software as a Service) designed to manage
infinite 3D products on multiple platforms. (Marxent Labs LLC, 2014)
Google’s projecttangoandmagic leap,Microsoft’s HoloLens
indicate the involvement in the AR sector. Recently, Apple
has also acquired augmented reality company: Metaio.
(Constine & Miller, 2015)
Wikitude,layarare the AR basedbrowser,providinglocation
based experiences and assisting to find various items based
upon AR technology. (CUTLER, 2009)
Automobile giant Volkswagen uses AR app called MARTA
(Mobile Augmented Reality Technical Assistance) aimed at repair technician and car dealers (Zibreg,
2013).
The Umpire Decision Review System (UDRS) is an AR based system used in cricket for reviewing the
controversial decisions made by the on-field umpires. (espncricinfo.com, 2015)

2 Background
Augmented Reality (AR) is a variation of Virtual Environments (VE), or Virtual Reality as it is more
commonlycalled. VirtualReality completelyimmerseauserinasyntheticenvironment.While immersed,
the user cannot see the real world around him. (Azuma, 1997)
The furthersectionunderbackgroundconsistsof working mechanismof AR, its types, key components
used and the application areas.
2.1 Working Mechanism of Augmented Reality
The figure belowprovidesinformationonhow ARtechnologyworksinoneof the ARintegratedHardware
i.e. HMD (Head mounted display).

2.2 Types of Augmented Reality
There are twoprimarytypesof AR implementations: MarkerBasedandMarkerless.Markerless mayalso
be referred to as Location-based or Position-based AR. (Dartmouth College Library, 2015)
The brief working mechanism of these two types of Augmented Reality has been described below.
i. Marker-based
Markersworkbyhavingsoftwarerecognizeaparticularpattern,suchasabarcode or QR/2Dcode,

ii. Markerless
Markerless/Location-basedapplicationsuse the abilityof aparticulardevicetorecorditsposition
in the world and then offer data that’s relevant to that location: finding your way around a city,
naming the mountains, monuments around you or the stars in the sky. (Ooi, 2014)

3 Analysis
This chapter analyzes Augmented Reality technology from different perspective. This includes its
advantages, disadvantages and also the analysis based on various graphs, charts and stats.
3.1 Advantages of Augmented Reality
Under this topic advantages of Augmented reality has been identified and briefly elaborated.
i. Better Navigation
Wikitude Navigation helps drivers and pedestrian in navigation with turn-by-turn GPS based guidance
usinga unique augmentedrealitydisplay.Itaddsconvenienceandsafetybenefitsof neverhavingtotake
their eyes off where they’re going. (Wikitude, 2015)
ii. Improves Education and Educational Sector
The 3D objectviewersfrom AugmentedRealityDevelopmentLab (ARDL)increasesstudent’sinvolvement
makingteachingand learningprocessmore interactive.Teachercan usedAR alongwithVR to showthe
bully, how harmful his activities are from the perspective of victim. (Kluwe, 2014)
iii. Aid those with disabilities
AR assists people with disabilities. LookTel Recognizer is an iOS apps that aid visually impaired or blind
people to recognize everyday objects. (LookTel, 2015)
iv. Being multi-modal increase Productivity
Technology like Google Glass responds to voice commands, taps, gestures or head movements. This
means that anyone from any field could use the glass for increased productivity. (Galer, 2014)
v. Helps in sports for better decision making and achievement tracking
Coaches from the German Bundesliga football club TSG 1899 Hoffenheim have tested Google Glass to
gain insights on player performance during practice helping to make better decisions. (Galer, 2014)

vi. Provides advantage with diminished reality
Technical UniversityofIlmenau in Germanyhave developedsoftware thatcanremove objectsfromlive
videos. Forexample:Architectscanimagine whatasite will looklikeafter abuildinghasbeendemolished.
(Khanna & Khanna, 2011)
3.2 Disadvantages of Augmented Reality
This topic discusses the disadvantages of augmented reality.
i. Privacy
Maintaining privacy wouldbe much harder. Using AR facial recognition,a digital profile of an individual
can be pulled up on anyone that can be seen.
ii. Augmented Bullying and Harassment
Bully may paste a marker on the back of the victim which on viewing throughAR tech shows “Kick Me”
sign. Similarly, someone can find the nude pictures of the others who are walking by simply looking at
them through AR tech. (Gordon, 2010)
iii. Augmented Terrorism
High-profile targets could be tagged and then tracked through a crowd of any size; densely populated
areas could be monitored and shown exactly when they have reached a peak density for maximum
devastation. (Gordon, 2010)
iv. Disadvantage with diminished reality
It couldbe destructive tool forspreadingapathyinsociety. If youdon’twanttosee anyhomelesspeople
on the street,you can program the AR glass to do so,and the software will keepdeletingthe poorlying
on the sidewalks and you will never feel guilty of not helping those. (Khanna & Khanna, 2011)

4 Conclusion
This chapter concludes the report with critical evaluation and future escalation of the topic.
4.1 Critical evaluation
Based on the graphs and charts presented in the analysis chapter, it is expected AR, VR market would
heavilygrowby2020. ARbeingone of the mostpromisingtechnologiesisgainingitsimportance invarious
fieldsof application withitsmulti modal support.Whereas,VRcurrentlyseemstobe constrainedwithin
Gaming and entertainment.
From the perspective of current giants, there are pluses and minuses. Facebook placed an early bet on
Oculus, which might win VR but not address the larger AR market. Google learned from Glass, and had
the foresighttoinvestin MagicLeap.HoloLenscouldallow Microsofttoregainthe gloryitlostto Applein
the lastdecade (DIGI-CAPITAL,2015). Apple acquiringMetaioowning171 patentsworldwide (Eadicicco,
2015) and hiring of an audio engineer form Microsoft’s HoloLens gives the clear insight that Apple’s
starting to build out its AR initiative (Sullivan, 2015).
Since the development of first head mounted display in 1968 to the failure of google glass, AR have
continuously making the headlines.Different companies stepping up in AR, VR tech are competing each
othertomake the betterproduct.Inthe contextof Nepal,particularlyyouthsare keenlyinterestedtoget
handson experience withOculusRiftandHoloLens. Hence, thistechnologyhasable to grab attentionof
people from all over the world.
Even though AR may assist in differentareasbut it couldalso become handyfor notoriousactivitieslike
privacy breaching, harassment etc. This could be the major challenge which needs to be address
sensitively.
4.2 Future escalation
It is very obvious that AR is a big business and growing every year. The future for AR is immense.
It is expected that by 2016 the revenue for AR technology will be more than 600 billion dollar and 2.5
billionARappswill be downloadedontosmartphonesandtabletsby2017. ( the digital marketingbureau
, 2015)
Similarly by 2020, 103 million automobiles will contain AR technology. ( the digital marketing bureau ,
2015)
Microsofton collaborationwithNASA have developsoftware called OnSight, enablingscientiststowork
virtually on Mars using HoloLens. (NASA/JPL-Caltech, 2015)
Facebook’s CEO Zuckerberg has also confirmed that the instead of working only in VR, they will also
engage themselves with AR technology. (Amber, 2015)
Niantic is preparing to launch location based AR game: Pokémon Go which has secured $20M funding
from Google, Nintendo and The Pokémon Company.
