Abstract
As the use of computers is ever increasing new and easier methods of interaction with the system are needed. Augmented reality
makes any application more interactive and full of life making it easier and attractive. The conventional mouse and keyboard can
be replaced by human hand to interact with the computer. Addition of augmented reality to do so will make it more attractive. The
same concept of using hand as interaction device and adding augmented reality can be used for retrieval of information from the
internet. This will make our daily tasks relating computer easier and fun increasing productivity.

1. INTRODUCTION
In today’s time computers have become inseparable
component to human beings. Even end users who have none
or little technical knowledge interact with computers many
times a day. Since the introduction of computers, the
keyboard has been the primary input device. The
introduction of mouse as a consumer peripheral in 1984
added another important input device to the computers.
Since then a little has been changed in the way we interact
with the computers. There is a need to replace the
conventional ways of interaction with device that a human is
more comfortable to use making it more attractive and
intuitive. Addition of augmented reality will make
interactions more realistic for a user.
2. LITERATURE SURVEY
Human Computer Interaction is the form of development of
human interaction with computers. The HCI will further be
developed to make the interactions more intuitive.
Augmented Reality enhances the user experience of Human
Computer Interaction. Augmented Reality is a combination
of images generated by computer with real images.
Augmented Reality deals with image processing. Various
Image Processing algorithms are required in order to make
Augmented Reality work. The use of human hand as a
virtual object to interact with a computer makes an
environment more user friendly. Natural hand movements
can be used as a medium of communication with a machine
making interactions practical and intuitive. Human centred
designs and innovations are the primary considerations for
designing of systems with larger life span and more
productivity. Hence the system is proposed.
Various systems involving the use of Augmented Reality to
make applications more real are used. The main objective of
AR applications is to make the interactions natural and
intuitive. AR enables the user to interact with the computer
objects in a similar manner like real world objects.
Siegl et al. has introduced a concept of 3D cursors for
interactions in the applications. The user just has to point
with a finger or hand in the space towards the desired
button. The camera will then capture the position and make
the further processing.
Rafael Radkowski has presented a system that uses aug-
mented reality for interactive assembly of 3d models. The
application tracks and monitors various movements and
gestures using Microsoft Kinect video camera to take inputs
from the user. It allows the user to interact and manipulate
with the system.
Ching-Hao Lai has proposed various algorithms in his
application for in vehicle computers that a driver uses in
particular like GPS. The application taks inputs from users
through various movements of hand and uses them to
provide input the in vehicle system. The application aims at
removing or reducing the risk of accidents that are caused
due to distractions that are caused due to manual interaction
of driver with in vehicle devices like GPS, music players
etc.

3. PROPOSED SYSTEM
We propose a system in which the user can interact with the
computer without the use of conventional keyboard and
mouse. The user makes use of his hands to give commands
to the system. In order to make the interaction more intuitive
and realistic the human hand is used. Humans are very
comfortable in making interactions using human hand. Even
a child can easily and effectively make use of his hands.
Hence the hand can be used as a perfect device for
interaction.
The system consists of two modules one for desktop control
and other for information retrieval from the internet. The
desktop control consists of various menus and buttons that a
user frequently needs to access for example Media Player.
User will see a Virtual menu on the desktop that will
comprise of buttons to select from. Virtual menu is
displayed on live captured feed for button selection.
The second module consists of daily information retrieval
from the internet. We rely on the internet heavily for many
of our activities. The application will allow users to access
the information from the internet in a more realistic and
intuitive manner making use of hand movements merged
with augmented reality. Accessing information like news,
stock updates. Weather forecast will become more real life
than just some information displayed by a machine. User
will feel like a part of the system as he himself will be
interacting with the information without the presence of any
device to mediate between the computer and the user.
4. SYSTEM ARCHITECTURE
The first action is performed with the help of a web cam.
The camera captures the movements of the hand in the form
of video feed. Frames derived from the video feed are used
for further processing by the system. Then the retrieved
frames are blurred using Gaussian Blur. It is used so that the
image structures retrieved from image frames are enhanced
at various scales. The blurred images are converted from
RGB to HSV format (Gray Scale Conversion). The HSV
format offers more accuracy than the RGB. It offers more
distinct relation between the colours. Then the gray scale
image i.e. the image in HSV format is converted into binary
format by means of Thresholding. Thresholding converts the
image in the form of only black and white i.e. only two
value’s 0 and 1. The next step is blob detection. The Blobs
from the black and white image are detected using blob
detection algorithm. It does this by identifying group of
white pixels. The position of the hand is recognized using
image subtraction that calculates the position of the hand
and processes the position to choose the selected menu. The
position of the hand states the menu and a command is sent
into the database to open the selected menu.
5. CONCLUSION
This paper proposes a system that will use the human hand
as an input device to interact with the computer to replace
the existing conventional input devices ie keyboard and
mouse. The system aims at making the user interactions
with the computer more realistic and intuitive. It shall allow
users to control desktop by using their hands. Also it shall
allow them to interact with the information on the internet
by themselves without any mediatory device. Augmented
reality makes the interactions more attractive and takes the
user experience to another level. Augmented reality is
already in the process of changing things as we know them.
The proposed system uses this concept of Augmented
Reality to entirely change the user experience and allow
them flexibility and comfort in doing their daily interactions
with the computer and the internet.
