1.Introduction

Augmented reality is a live, direct or indirect, view of a physical, real-world environment

whose elements areaugmented by computer-generated sensory input such as sound, video,

graphics or GPS data . Augmented Reality is a type of virtual reality that aims to duplicate

the world's environment in a computer. Virtual reality (VR) is a virtual space in which

players immerse themselves into that space and exceed the bounds of physical reality. It

adds information and meaning to a real object or place. Augmented reality is characterized

by the incorporation of artificial or virtual elements into the physical world as shown by the

live feed of the camera, in real-time. Common types of augmented reality include

projection, recognition, location and outline.

Projection: It is the most common type of augmented reality, projection uses virtual

imagery to augment what you see live. Some mobile devices can track movements and

sounds with a camera and then respond. Virtual or projection keyboards, which one can

project onto to almost any flat surface and use, are examples of augmented reality devices

that use interactive projection.

Recognition: Recognition is a type of augmented reality that uses the recognition of shapes,

faces or other real world items to provide supplementary virtual information to the user in

real-time. A handheld device such as a smart phone with the proper software could use

recognition to read product bar codes and provide relevant information such as reviews

and prices or to read faces and then provide links to a person's social networking profiles.

Location: Uses GPS technology to instantaneously provide you with relevant directional

information. For example, one can use a smart phone with GPS to determine his location,

and then have onscreen arrows superimposed over a live image of what's in front of the

user and point him in the direction of where you need to go. This technology can also be

used to locate nearby public transportation stations.

Outline: Outline is a type of augmented reality that merges the outline of the human body

or a part of the body with virtual materials, allowing the user to pick up and otherwise

manipulate objects that do not exist in reality. One example of this can be found at some

museums and science centers in the form of virtual volleyball. Although the player can stand

and move on an actual court, the ball is projected on a wall behind him, and he can control

it with an outline of himself, which is also projected on the wall Using the concept of

augmented reality our project focuses on creating a very useful android mobile based

application. The idea is to allow the user to view the virtual object in the real world. The user

could provide images of the object which would be the front, back, top, bottom, and left

and right side pictures of the object. They will be placed onto a 3D cube which will make

up the complete virtual object. Thus an extended environment will be created through the

amalgamation of real world and generated object and it will appear as th ough the real-world

object and virtual object coexist within the environment. In order to use this application, the

user will first need to acquire a marker. A marker is a piece of paper with black and white

markings. This is used to display the augmented object on your mobile phone‘s screen.

Marker-based augmented reality uses a camera and a visual marker which determines the

centre, orientation, and range of its spherical coordinate system. Once the marker is

present one can view augmented objects. Virtual object interaction is another added

feature wherein the user can rotate or change the orientation of the object according to his

requirements.

VIRTUAL REALITY

The term "artificial reality", coined by Myron Krueger, has been in use since the 1970s;

however, the origin of the term "virtual reality" can be traced back to the French

playwright, poet, actor, and director Antonin Artaud. Virtual Reality is a computerized

simulation of natural or imaginary reality. Often the user of VR is fully or partially

immersed in the environment. Full immersion refers to someone using a machine to shield

herself from the real world. VE is the term used to describe the scene created by any

computer program in which the user plays an interactive role within the context of the

computer generated three dimensional world. The user represents an actor within the system

and has an essential presence within the virtual world. Virtual reality (VR) is a term

that applies to computer-simulated environments that can simulate physical presence in

places in the real world, as well as in imaginary worlds.

Advantages:

Many different fields can use VR as a way to train students without actually putting

anyone in harm's wa y. This includes the fields of medicine, law enforcement, architecture

and aviation. VR also helps those that can't get out of the house experience a much fuller life.

Doctors are using VR to help reteach muscle movement such as walking and grabbing as

well as smaller physical movements such as pointing. The doctors use the malleable

computerized environments to increase or decrease the motion needed to grab or move an

object. This also helps record exactly how quickly a patient is learning and recovering.

Total immersion within environment.

Increased user presence perception within system.

Facilitated production of an entirely designed environment.

Existing technologies for advanced interaction.

Real-time graphical environment generation possible.

Disadvantages:

The hardware needed to create a fully immersed VR experience is still cost prohibitive. The

technology for such an experience is still new and experimental. VR is becoming much more

commonplace but programmers are still grappling with how to interact with virtual

environments. The idea of escapism is common place among those that use VR

environments and people often live in the virtual world instead of dealing with the real one.

One worry is that as VR environments become much higher quality and immersive, they

will become attractive to those wishing to escape real life. Another concern is VR

training. Training with a VR environment does not have the same consequences as training

and working in the real world. This means that even if someone does well with simulated

tasks in a VR environment, that person might not do well in the real world.

Not suited to real-world interaction.

Despite advances in technology equipment is still expensive.

Auxiliary senses not stimulated.

Possible lag in motion-display system.

III. AUGMENTED REALITY

Augmented Reality (AR), also known as Mixed Reality, aims to combine virtual and real

scene together to achieve that virtual ones are belong to the real world. Being characteristic

of integration of virtual and real scene, many applications of Augmented Reality are

emerging, such as in field of education, medical treatment and entertainment.

Fig 1: Real desk with virtual lamp and two virtual

chairs [5].

Figure 1 shows an example of what this might look like. It shows a real desk with a real phone. Inside this

room there are also a virtual lamp and two virtual chairs. Note that the objects are combined in 3-D, so that

the virtual lamp covers the real table, and the real table covers parts of the two virtual chairs. AR can be

thought of as the "middle ground" between VE (completely synthetic) and telepresence (completely real).

Goals of Augmented Reality:

To challenge the impossible.

To create virtual environment for a more rich user experience.

To integrate it into daily lives to help the masses.

To achieve feats which are limited in real world.

To enhance imagination of youths.

Types of Augmented reality:

There are two types of simple augmented reality: marker-based which uses cameras and

visual cues, and marker less which use positional data such as a mobile's GPS and

compass. (Johnson et al, 2010)

Marker based

Different types of Augmented Reality (AR) markers are images that can be detected by a

camera and used with software

as the location for virtual assets placed in a scene. Most are black and white, though

colours can be used as long as the contrast between them can be properly recognized by a

camera. Simple augmented reality markers can consist of one or more basic shapes made

up of black squares against a white background. More elaborate markers can be created

using simple images that are still read properly by a camera, and these codes can even take

the form of tattoos.

Fig 2: A Simple Marker

A camera is used with AR software to detect augmented reality markers as the location for

virtual objects. The result is that an image can be viewed, even live, on a screen and

digital assets are placed into the scene at the location of the markers. Limitations on the

types of augmented reality markers that can be used ar e based on the software that

recognizes them. While they need to remain fairly simple for error correction, they can

include a wide range of different images. The simplest types of augmented reality markers

are black and white images that consist of two-dimensional (2D) barcodes.

Marker less

In marker-less augmented reality the image is gathered through internet and displayed on

any specific location (can be gathered using GPS). The application doesn‘t require a marker

to display the content. It is more interactive than marker based augmentation.

Fig 3:Marker Less AR

The only real difference from a consumer‘s perspective is that the surface the object is

sculpted on doesn‘t have to have that.

IV. MARKER DESIGN , DETECTION AND RECOGNITION

METHOD

Markers are square and constituting of black thick border and black graphics within its

white internal region. The advantage of using black and white colour is to separate

marker from background in grabbed frame easily. Internal region of a marker marks

identifier of it. In term of projective geometry, square markers in real world could not be

square after projecting onto image plane, in other words, internal graphics in markers

often display in distortion. When recognizing them, image unwrapping is necessary.[4]

The procedure of unwrapping image is shown in Fig.4.

Fig 4:Procedure of unwrapping marker image to find ID

The calculation of marker unwrapping could be described as follows: as

four corners of a marker are acquired after detecting grabbed frame. Positions of four

corners are known in the real world as . Homography matrix H could be

calculated in (1). By H points in internal region of marker could be unwrapped to formal

one.[4]

After that, unwrapping image are used to match templates in matching method or decode in

code-decoding method respectively.

V. PROBLEM

STATEMENT

The proposed system aims to provide an environment that will help the users to place

artificial 2D as well as 3D objects into real world through the use of AR Markers. The

proposed system also allows the user to decide, where to place the object in real world.

Once the object has been placed in the scene, it will be displayed accurately according to

the perspective in the original scene, which is especially challenging in the case of 3D

virtual objects. The proposed system solves the problem of viewpoint tracking and

virtual object interaction. The main advantage of the proposed system is that, it is

customer oriented and not product or service oriented thus allowing the users to augment

a product of their wish. There would be option to move the Virtual object in the virtual

space with a marker.

VI. WHY ANDROID OS

Since the advent of 2010 more and more stress has been given on the usage of Free and

Open Source Software (FOSS).

Android is leading the current O.S market as shown in figure 5, because it is open source

and developed by a consortium of more than 86 leading M.N.C‘s called Open Handset

Allowance (O.H.A). Android also is stated as one the most rapidly growing technologies.

More and more applications have been developed and modified by third party user.

Fig 5: Smartphone OS

market shares

Moreover, the Android O.S is user friendly. It has a great performance and processing power. Thus, the

proposed system is being developed for the most rapidly emerging and flexible O.S- ―ANDROID‖

VII. PROPOSED

SYSTEM ARCHITECTURE

Fig 6: Architecture Block

diagram

An AR application is composed of the following core components:

Camera

The camera component ensures that every preview frame is captured and passed efficiently to the

tracker. The developer only has to initialize the camera to start and stop capturing. The camera frame is

automatically delivered in a device-dependent image format and size.

Image Converter

The pixel format converter converts from the camera format (e.g., YUV12) to a format suitable for

OpenGL ES rendering (e.g., RGB565) and for tracking (e.g., luminance) internally. This conversion also

includes downsampling to have the camera image in different resolutions available in the converted frame

stack.

Tracker

The tracker component contains the computer vision algorithms that detect and track real-world objects in

camera video frames. Based on the camera image, different algorithms take care of detecting new targets

or markers and evaluating virtual buttons. The results are stored in a state object that is used by the video

background renderer and can be accessed from application code. The tracker can load multiple datasets

at the same time and activate them.

Video Background Renderer

The video background renderer module renders the camera image stored in the state object. The

performance of the background video rendering is optimized for specific devices.

Application Code

Application developers must initialize all the above components and perform three key steps in the

application code. For each processed frame, the state object is updated and the applications render

method is called. The application developer must:

1. Query the state object for newly detected targets, markers or updated states of these elements

2. Update the application logic with the new input data

3. Render the augmented graphics overlay

Device Databases

Device databases are created using the online Target Manager. The downloaded device target database

assets contain an XML configuration file that allows the developer to configure certain trackable features

and a binary file that contains the trackable database. These assets are compiled by the application

developer into the app installer package and used at runtime by the Vuforia SDK.

Cloud Databases

Cloud databases can be created using the Target Manager or using the Vuforia Web Services API.

Targets are queried at runtime of the application using the cloud recognition feature that performs a visual

search in the cloud using sent camera images. In addition to the target data, the provisioned targets can

contain metadata which is returned upon query.

User-Defined Targets

A fundamentally different supported approach is the user-defined targets feature. Rather than preparing

targets outside of the developer, this feature allows for creating targets on-the-fly from the current camera

image. A builder component is called to trigger the creation of a new user-target. The returned target is

cached, but retained only for a given AR session.

PROJECT CONSTRAINTS

Augmented reality still has some challenges to overcome. Augmented Reality systems are expected to run in real-

time so that a user will be able to move freely within the scene and see a properly rendered augmented image.

The application

will be built for mobile phones which usually have low screen dimensions and resolution. It also adds additional

stress on the O.S because it requires high processing power to augment. Developers of the application are

supposed to have a thorough knowledge of Android O.S (Applications developed for) and Windows O.S

(Application developed in). Developers are also supposed to be familiar with ADK (Android Development Kit)

and Eclipse.

2. Title of paper: A Study on Tangible AR for interior design

Authors: Viet ToanPhan and Prof. SeungYeonChoo

Year of Publication: 2010

Summary: This research examined virtual furniture and adjustment work to create a new

design method using Augmented Reality technology for Interior Design education.

In particular, AR technology opens up many new research fields in engineering and

architecture. In an AR environment, design work can become more lively, convenient,

and intelligent. Plus, design work and manufacturing can be conducted at the same time

and I

close relationship with each other. With AR, the virtual products of graphic technology

are not only for simulation but also obtain real higher values.

Furthermore, ARtechnology can become a new animated simulation tool for interior

design, allowing the user to see a mixed AR scene through HMD, video display, or PDA.

It is also anticipated that the interactive potential can be increased according to the user‘s

needs.

4. Title of paper:Marker Based Augmented Reality Using Android OS

Authors: Mr. Raviraj S. Patkar, Mr. S. PratapSingh,Ms. Swati V. Birje

Year of Publication:2013

Summary:Augmented Reality or AR is an emerging technology in which one‘s

perception of the real-time environment is enhanced by superimposing computer-

generated information such as graphical, textual, or audio content, as well as objects onto

a display screen. The proposed application is an android mobile based application which

will be compatible with all the existing and upcoming versions of the operating system.

The idea is to allow the user to view the virtual object in the real world using a marker

based AR system. The user could provide images of the object which would be the front,

back, top, bottom, left and right side pictures of the object. They will be placed onto a

3D cube which will make up the complete virtual object. Thus an extended environment

will be created through the amalgamation of real world and generated object and it will

appear as though the real-world object and virtual object coexist within the environment.

The advantages of this application as compared to the already existing 2D application are

that it would display object in 3D and enable the user to rotate it virtually. It is

inexpensive as the user nee d not actually purchase the object to see how it fits in the

environment, instead he can try before the purchase itself.

2.3 Summary of field survey

The Interior Design Domain

The world of virtual objects in an AR application incorporates the information that makes

sense at the application level and is relevant to the users. Conceptually, this is a shared data

base of logical objects, the ―model‖. Because of the replicated architecture, the model is

available as a copy in each instance of the application. The structure and type of the model is

dependent on the application. In the interior design example we deal with a model that stores

geometric data for a set of furniture. Each model object represents a piece of furniture, and

maintains geometric transformations and visual attributes relevant to the object. The model

objects are organized hierarchically, so that it is possible to select and interact with groups of

furniture.

An interactive representation of the model in the user interface is called a ―view‖. Views are

created based on a specific interpretation of the model information. The interpretation is

determined by the type of view, the type of model data, and the context of the interface. As an

example, consider the furniture model of the interior design application and two views, a

graphics rendering of the furniture and a browser for the items in the model. The rendering

creates geometric primitives appropriate for the type of furniture, and geometric

transformation and attributes are used directly to customize the presentation. On the other

hand the browser creates a list of labels taken from the model objects and ignores all

geometric information. Both views have presentation parameters that are not bound by the

model interpretation and can be used for local customization of the interface.

The interpretation is not so straightforward for non-geometric model information.

Highlighting a view object, for example, can be used to indicate a current selection in the

model, but different views are likely to use different methods to show the highlight. This type

of feedback becomes more complicated in multi-user applications with local selections at each

site. In a distributed application, information about the state and actions of remote users

becomes part of the model. It is important to give each user an awareness of who is

participating and what other participants are doing. The interior design application makes use

of an object browser that is capable of showing remote selections. In general, it can be a

challenging task for the interface builder to find a concrete visualization for some abstract

structure or behavior in the model.

The model-view mechanism is well known in the area of user interface construction, and used

to implement a separation between interface and application functionality. The importance of

separability for modularity and independent development of interface components has been

recognized even in non-distributed environments, where it is considered good software

design. Yet separability becomes an indispensable architectural feature for distributed

interfaces, at least for those with a need for object-level sharing. By using the model-view

paradigm, we achieve the necessary independence between the conceptual objects of the

global model and the objects and manipulations of a particular interactive view.

New tools:

AR Tools:

1. Qualcomm Vuforia SDK: A very sophisticated SDK for handelling AR based apps with

support for various objects.

2. Unity3d Pro :Used instead of OpenGL renderer,to render graphics and scenes to the

device.

3. ARCamera Prefab: Replacing the main camera can ensure that we can use the device

camera as an input device.

4. Node.js: For networking and connections management to our cloud database.

5. Open Source Cloud Service like Hadoop, CloudFoundry: for storing image targets

database.

List some relevant current/open problems.

Environment: How can we deal with dynamic aspects (color, illumination) of environments?

While (indirectly) some work has been performed on visual patterns, in general the structure,

colors, and illumination conditions in an environment are ignored or adapted for manually. For

example, dynamically adaptable color schemes that adjust to the environment conditions could

be of great benefit to solve some of the object segmentation and depth problems that are caused

by the environment.

Capturing: How do high-definition and HDR cameras coupled with improved display resolution

change perception on small devices? These camera types are currently attracting interest: they

are suitable for solving perceptual problems associated with reso- lution mismatches, and the

improvement of the color gamut and contrast. However, the perceptual consequences of using

HDR cameras with non-HDR displays should be carefully studied, since skewed colors can be

counterproductive.

Capturing: How can we design systems with dynamic FOV, and what effects do they have? The

FOV mismatch introduced by using wide-angle lenses with small FOV displays causes scene

distortion. This could be addressed through dynamic FOV (e.g., by using liquid lens technology).

Similarly, (software) methods that adapt to the actual position of the eye relative to the display

could prove useful. It is unknown, though, if such methods are achievable and if they will cause

perceptual disturbances.

Augmentation: How can we further improve AR methods to minimize depth-ordering

problems? X-ray vision is useful to look through objects in the real scene. However, depth

ordering and scene understanding in such systems still requires improvement: one direction that

may yield benefits is multi-view perception. Similarly, label placement in highly cluttered

environments still suffers from depth ordering problems. Layout and design can also be

improved—apt associations need to be implemented that uni- quely bind a label to an object.

Cues that specify potentially dis-ambiguating information related to the real world (e.g., a street

address) might be one possibility in cluttered city environments.

Display: Can we parameterize video and rendering quality to pixel density, to support

―perceptually correct‖ AR? In particular, improvements in camera capturing quality and pixel

density will make it possible to use very high resolution imagery on very small screens, but, to

what extent do we need to change the image‘s visual representation to maximize its

understandability? Additionally, what is the maximum disparity between video and rendering

resolution before noticeable perceptual problems arise? And, is it possible to parameterize the

offset effects between video and rendering, for example with respect to mismatches or abstrac-

tions? Finally, how much rendering fidelity is truly needed? For example, depth does not seem to

be affected much by fidelity (see Section 4.3, rendering and resolution mismatch).

Display: What is the weighting of perceptual issues among dif- ferent display devices? One of

the most pressing questions is the actual effect each problem has on the various display types:

com- parative evaluations are required to generate a per-device weight- ing of perceptual

problems, which would be particularly useful for determining those problems that should be

tackled first. In the next section, we provide an initial overview of the differences between the

various platforms.

User: What are the effects of the dual-view situation on percep- tion and cognition in AR

systems? In particular, handheld and see- through devices introduce a dual view situation, which

may help to verify ambiguous cues obtained from display content. Howev- er, its true effects are

unknown; for example, disparity plane switching is expected to be counterproductive, but are the

advan- tages of dual-view more important, and, how could we possibly minimize the effects of

disparity plane switching?

User: What are the effects of combinations of these problems on the perceptual pipeline? A

single problem can have effects on different stages, as evidenced by our repeated mentions of

some issues in multiple sections; for example, sunlight can make captur- ing, display, and user

perception difficult. What may be even more important is the actual combination of problems

that accumulate through the pipeline: for instance, low-resolution capturing may affect multiple

subsequent stages in the perceptual pipeline, and problems may become worse at each stage. The

question is how much the accumulation affects perceptual problems on dif- ferent platforms.

4. Analysis, Design and Modeling

4.1 Overall description of the project

In the case of interior design, the designer essentially applies the three basic principles of interior

design: color, scale, and proportion within a predetermined space. Thus, the proposed AR system

is focused on giving the user the flexibility to design using these three basic principles.

Therefore, in the proposed AR environment, the user is able to adjust the properties of virtual

furniture and create different arrangements in a real environment.

The era of mobile web application has just started, and

there is a long way for it to march. Development of mobile web application will be emphasized

on following aspects:

1) More and more sensors will be added to mobile phones, so new APIs to use those capabilities

will bring brand new applications to users.

2) Multimedia capabilities will be enhanced and engine will support more types of multimedia

such as flash and svg .

3) The dedicated Integrated Development Environment (IDE) will be improved to accelerate the

applications‘ development. Visualization programming and JavaScript debugging will be the

most important functions of the IDE.
