ABSTRACT
A mobile application which can save time,
effort and money by giving technical video
explanation based on the recognised image
for learners. The collected video information
contains all the detailed explanation of the
scanned image done by the user. This
application groups Augmented reality , 3d
objects , sound , video , AI for image
recognition into an easy and compact
application for the benefit of the every
learner. This web application is built C#,
UNITY, VUFORIA with the help of
Vuforia server connected by asserts. This
mobile application serves as an easier way
to access details and documentaries related
to recognised object. It includes an
automatic AR Camera and image target
along with the video player which makes it
easier for recognising the image and to
learn. The database is done with Vuforia
cloud database. The UI provides an
excellent user friendly environment that
makes the communication more interactive.
Keywords Mobile application, Vuforia,
Unity, AR Camera, C#.
I. INTRODUCTION
The application generally refers to
the word tutor with hospitality. Learning is
the process of acquiring new, or modifying
existing, knowledge, behaviors, skills,
values, or preferences. The ability to learn is
possessed by humans, animals, and some
machines; there is also evidence for some
kind of learning in some plants. Interactive
learning is a globally accepted career field
and academic field of study as it promotes
the software application too as shown in
Table 1.

II. EXISTING SYSTEM
Although, mobile application on
learning is a blue eyed vision of people of
cities, it is important to handle and manage
this[1]. There are developed mobile apps
and web applications for this scenario, but
have equalized bane comments on them.
Already existing apps are, “eureka.com”,
“educomp.com”, “amazon kindle”,” khan
academy” and other apps are only given for
guide basis.
eureka.com
The application of eureka has been rated as
(3.6/5), has a certain disadvantages of bugs,
and lags in time and has no AR or AI. It is
only available on web.
educomp.com
The application next is “educomp”, it is the
currently used app in schools and is rated as
(4.0/5), it is not accessible offline and it just
act as showcase of concepts.
amazon kindle
The next app is,” kindle”, it is rated as
(4.2/5) it is the app which only consists of
books. It is rated bad because of it
complexity in understanding the terms of
cost.
khan academy
The next named application is,” khan
academy” it is an updated version of
educomp.com . It contains transactions and
has login & registration problems. This app
has a highly rated and has a disadvantage of
slow pace,bugs,complexity of understanding
and has difficulties in entering the datum.
These are the common set of disadvantages
faced by the people who are using this
applications. Hence, our application has
been programmed with the help of
UNITY,VUFORIA, UNITY CLOUD , C#
software to overcome this set of
disadvantages[4]. Hence, the proposed app
is said to be user friendly along to give a
helping hand for the learners and the
students[6].
III. PROPOSED SYSTEM
Unity is an integrated platform to work with
c# , vuforia and AI[2]. This application
programs helps to give a great user
interface[2] as shown in Figure 2. The
UNITY CLOUD platform provides the best
use of storage and vuforia license gives a
better connectivity with the AI image
recognition and UNITY CLOUD[5] as
shown in Figure 1.

IV. VIRTUAL TUTOR APPROACH
Figure 3.virtual tutor workflow
Virtual tutor
The proposed application provides an
excellent information on the recognised
image[8] as shown in Figure 3. This learner
friendly application consist of a AR camera
which is used to recognise the image
provided by the user[3].The vuforia package
which is intergrated is used to identify the
image provided by the user[5] .This AI
technology identifies the exact image and
relates it with the UNITY CLOUD for exact
explanation video.If there is a presence of 3d
motion objects, it will be enable
automatically[7]. This app is very
responsive to run the application in all
android , ios, web application. It also
provides an simple UI for the learners who
uses the app.

VI. ADVANTAGES
1. It provides a great student friendly
and as well as mobile friendly
interface.
2. It is used to identify the particular
image in a book.
3. It contains basic learning videos
stored in cloud.
4. It is memory as well as RAM freed
mobile application.
5. It contains a dynamic cloud storage
of learning points which can be
accessed by internet.
6. It recognize a particular image and
infer it with the AI technology which
is integrated with vuforia.
7. It also highlights the important
keyword present in the book.
8. It also include 3d moving objects for
better demonstration of a concept.
9. Better sound quality of the video
with faster retrival.

VII. CONCLUSION AND FUTURE
WORKS
The tremendous growth in mobile
application development is used worldwide
today. Mobile applications are evolving rich
and fast user experience. The ultimate goal
is to provide a successful user interface to
the users in an efficient manner at ease and
also to save the time. This application helps
the learner to clear their queries and to learn
more on the specified topic.The
applications, “virtual tutor” gives the facility
in recognizing the particular image given by
the user and teach more on the image to the
user. It also generates a video response after
recognizing the image. The application
provides an user interface that is very much
user friendly. The video also used the 3d
object motion for interactive learning which
is responsive. The mail is also sent to the
customer for the conformation process. By
this we conclude by saying, this short hand
application en-routes the people’s view in
clearing queries and understanding a
concept . It provides all time support to
people who uses the application.
