CHAPTER 1

INTRODUCTION

1.1 Project Background

Virtual Reality (VR) is the use of computer technology to create a

simulated environment. VR puts the user inside an object, unlike traditional

user interfaces. Users are immersed and able to communicate with 3D

environments instead of seeing a screen in front of them. The computer is

transformed into a gatekeeper for this artificial world by simulating as many

senses as possible, such as sight, hearing, touch, and smell. The only limits to

near-real VR experiences are the availability of content and cheap computing

power.

The project Virtual Cars Showroom that will developed is to allow

targeted user walk through the exhibition and see the exotic cars being

displayed. This project is a rare treat for car enthusiasts in Malaysian. The

project entitled “Virtual Cars Showroom” focusing on exotic cars. The cars

will be assigned by their brand. User can also see the details about the cars,

the cars sound and the interior with this application. The videos will also be

display. The main purpose of the project is to help Malaysian people learn

more about exotic cars even at home or anywhere using the latest technology.

2

1.2 Problem Statement

It seems like a few of problems that we can see a long time to develop

this project is that not everyone can see exotic cars in Malaysia. There’s

nothing quite like spotting a highly limited and desirable road machine

zipping by during a commute. Though that doesn’t happen very often

because it is very rare in Malaysia. Exotic cars exhibition requires money

and time to access. Lack of exposure about exotic cars details in virtual

reality mobile based is also the problem.

1.3 Objective

There are three aims that need to be achieved in this project. The objectives

are as follows:

i. To study mobile application that give convenience to

the people emerging world of virtual reality with

supported by Google Cardboard.

ii. To develop a virtual reality application that can help

Malaysian in familiarizing with the exotic cars.

iii. To test the virtual reality application is functional.

3

1.4 Scope

User Scope:

The target user for this project is suitable for people aged 17 and above.

o Suitable for driving age

Project Scope:

3D Cars Model.

Cars sound.

Assign car by brands.

Videos.

There is 5 brands and 3 cars each brand.

User can see the interior in 1 of the cars in each brand.

Use Google Cardboard or VR Box as the main input device.

Interesting background music.

1.5 Limitation of Work

A limitation of work is any restriction that defines a project’s limitations or

the limit of what the project is expected to accomplish. The limitations in

conducting this application are:

i. Available for Android version only

ii. Mobile based application

iii. Need VR headgear to use the virtual reality

iv. Gaze interaction

4

1.6 Expected Result

It is expected this application is to help and give a great experience to

user. To see an exotic car, the user gets to know more about the cars and the

user can also see the interior of the cars. Other than that, this application also

expected to create awareness about cars that are rarely or never be seen in

Malaysia. User also can knowledge the project as an interactive application

to use.

i. As an interactive tool for user in learning process.

ii. User able to explore the emerging world of virtual reality 3D

2.2 Virtual Reality

Virtual Reality (VR) is the use of computer technology to create a

simulated environment. Unlike traditional user interfaces, VR places the

user inside an experience. Instead of viewing a screen in front of them,

users are immersed and able to interact with 3D worlds. By simulating as

many senses as possible, such as vision, hearing, touch, even smell, the

computer is transformed into a gatekeeper to this artificial world. The only

limits to near-real VR experiences are the availability of content and cheap

computing power.

VR platform is where user can test to use VR experience. These

SDKs are the building blocks to create VR experiences such as mobile

apps, marketing experiences, and more. VR SDKs offer the tools to

perform functions such as cloning, moving 3D objects and adding. Google

Cardboard is a virtual reality (VR) platform developed by Google for use

with a head mount for a smartphone. To use the platform, users run

Cardboard-compatible applications on their phone, place the phone into

the back of the viewer, and view content through the lenses.

2.3 VR Types and Technique

There are many VR types and method as described below depends

on usages and suitability for VR application.

9

2.3.1 Simulation-based Virtual Reality

Simulation-based virtual reality considered both a type of VR

system and a method to realize virtual reality. A virtual reality system

based on simulation involves a computer-generated simulation or

approximate imitation of real- world environment or situations and

phenomenon.

Training is one of simulation-based VR's most common

applications. Driving simulator and flight simulator are notable

examples of pulling drivers and pilots into a simulated environment

that gives them a real impression of driving or flying an aircraft.

Figure 2.1 shows an example of Simulation-based Virtual Reality.

Figure 2.1 Simulation-based Virtual Reality

10

2.3.2 Computer based Virtual Reality

A virtual reality system based on a desktop simply involves

viewing a three-dimensional virtual world on a display device such as

a laptop or handheld display, both as a form of VR system and as

another tool of realizing virtual reality. This VR system-

differentiating feature is that it focuses on providing computer-

generated visual perception and does not use other sensory input

components such as a specialized positional tracking equipment.

Video games for the first person are example in Figure 2.2.

Figure 2.2 Computer-Based Virtual Reality

11

2.3.3 Head mounted display (HMD)

A specific method to realize virtual reality includes using a head-

mounted display or HMD to bring users to a virtual world that appears

to be enclosed in three dimensions. An HMD may include positional

tracking, audio and output elements, and haptic feedback. HMDs also

can be used to implement virtual reality system specific types. For

example, a driving simulator or a projected simulated real world

environment can include the use of an HMD as its main input-output

equipment. Figure 2.3 shows an example of Head-Mounted Display.

Figure 2.3 Head-Mounted Display

The method that used in this project is Head-Mounted Display

as it is the most immediately recognizable aspect of Virtual Reality.

Head-Mounted used in this project because it is affordable and

commonly used in VR project.

12

2.4 VR Platform

There are two platforms in order to complete the process of developing

virtual reality concept. Below are the comparison and details about the

platform in virtual reality.

2.4.1 Mobile base

Advantages Disadvantages

• Safe and secure — Mobile Apps

must first be approved by the App

Store.

• Easier to build due to the

availability of developer tools,

interface elements and SDKs

(Software Development Kits).

• Expensive to maintain and

update.

• It may prove difficult to get a

Mobile App approved by the App

Store

Table 2.1: Mobile based advantages and disadvantages

13

2.4.2 Desktop base

Advantages Disadvantages

• Standalone in nature and hence do

not face any hindrances resulting

from Internet connectivity.

• Less dependent on bandwidth

usage than Mobile Apps.

• Needs to be installed separately

on each computer. Also updating

the applications is cumbersome as

it needs to be done on every single

computer.

• Confined to a physical location

and hence have usability

constraint.

Table 2.2: Desktop base advantages and disadvantages

2.5 VR Software and Hardware

Human beings are visual creatures, and display technology is

often the biggest difference between interactive environments of Virtual

Reality and conventional user interfaces. With a variety of new hardware and

software solutions, wearable future is evolving but uncertain. Examples of

software and hardware that used in developing VR application are as

following.

14

2.5.1 VR software

Virtual reality is an artificial environment that is created with

software and presented to the user in such a way that the user suspends

belief and accepts it as a real environment. On a computer, virtual reality

is primarily experienced through two of the five senses: sight and sound.

There are two software that commonly used by the developer to develop

virtual reality application which is Unreal Engine and Unity 3D.

2.5.1.1 Unreal engine software

In the gaming industry, Unreal Engine is quite successful. The

software offers a lot of interesting features with flexibility to create

different games. Unreal Engine allows games to be developed from

basic 2D hand-drawn environments to immersive video gaming

experiences.

The tools has a custom built-in marketplace where users can

discover and buy assets and tools to enhance projects. Also, Unreal

Engine has a large follower base with a large community sharing

information, tutorials and the latest trends. Figure 2.4 shows an example

of Unreal Engine software.

15

Figure 2.4 Unreal Engine Software

2.5.1.2 Unity 3D software

Unity 3D is one of the front runners of computer engineering

for Virtual Reality, with the company rising from a little start-up to one

of the best solutions on the market.

Furthermore, Unity 3D has a scalable, super-good game engine

that fits well for solo developers and small development teams. Similar

to other competitors with cool advanced features, the software is

considered user-friendly. Figure 2.5 shows an example of Unity 3D

Software.

.

16

Figure 2.5 Unity 3D Software

The software used for this project is Unity 3D. Unity is the best

software for VR application development. It is very effective while

rendering 2D scenes. In this era of visual treats, Unity can very well be

used for rendering 3D images also. The quality offered is also relatively

good compared to other apps.

2.5.2 VR hardware

Virtual Reality hardware produces stimuli that override the senses of

the user based on human motions. The VR hardware accomplishes this by

using sensors for tracking motions of user such as button presses, controller

movements, eye and other body part movements. Below is the example of VR

hardware.

2.5.2.1 HTC Vive

The HTC Vive is a virtual reality headset developed by HTC

and Valve Corporation. The headset uses "room scale" tracking

17

technology to allow the user to travel in 3D space and use movement-

tracked handheld controls to interact with the environment. The HTC

Vive was unveiled during the March 2015 HTC Mobile World

Congress keynote. Design kits were launched in August and September

2015 and the first Consumer version of the system was released on June

7, 2016. Figure 2.6 shows HTC Vive Hardware

Figure 2.6 HTC Vive

2.5.2.2 Google Cardboard / Google VR SDK

Google Cardboard is a tool for virtual reality (VR) created by

Google to use a smartphone head brace. Named for its fold-out

cardboard viewer, the platform is intended as a low-cost device to

promote interest and innovation in VR applications. Users can either

create their own viewers from basic, low-cost components using

Google's published specifications, or buy a pre-produced one. Users run

cardboard- compatible apps on their mobile to use the network,

18

place the phone in the viewer's back, and display content through the

lenses. The Cardboard Software Development Kit (SDK) is available

for Android and iOS operating systems. The VR View of the SDK

allows developers to integrate VR content both on the internet and in

their mobile apps. Figure 2.7 shows Google Cardboard hardware.

Figure 2.7 Google Cardboard

VR Hardware that used in this project is Google Cardboard. The

low cost of Google Cardboard is one of the major reasons why Google

Cardboard used in this project. Hence, Google Cardboard is one of the

simplest virtual reality headsets to set up and use.

2.9 Chapter of Summary

This chapter discusses literature review that had been

reviewed during feasibility studies. The literature review helps developer

to discover the problem of previous research for application which needs

to be improves and overcome in this application development. Moreover,

there are some advantages and disadvantages in every technique that has

been considered in the research.

23

CHAPTER 3

METHODOLOGY

3.1 Introduction

This chapter discusses a methodology used for this project. The flow

of the project will discuss briefly to give more understanding of the design

and development of this application. There are many methods that can be used

for developing this project. The methodology used in this project is ADDIE

Model. Every phases of this methodology will be explained in the next sub

topic.

3.2 ADDIE model

The ADDIE model is the generic process which instructional

designers and training developers traditionally used. The five phases in the

ADDIE model are analysis, design, development, implementation, and

evaluation. The ADDIE model is a dynamic flexible guideline for developing

effective training and performance support tools.

24

In the design of educational materials, instructional theories also play

an important role. Theories like behaviorism, constructivism, social learning,

and cognitivist help shape and define the results of instructional materials.

Figure 3.1 show ADDIE Model process.

Figure 3.1 ADDIE Model

25

3.2.1 Analysis process

In the analysis phase, the problem of instruction is explained, the

learning goals and objectives are set, and the current knowledge and skills of

the learner and learner are established. The analysis phase involves are

requirement analysis, task analysis and instructional analysis. The activities

involve are identifying the problem statement, the goals and objectives of the

mobile VR application, existing knowledge and any other relevant

characteristics and the content of mobile VR application. The analysis is

carried out by doing market survey on existing articles and existing

application. So, the weakness of the existing application can be identified and

Virtual Cars Showroom will fulfill all of the weakness. The content of Mobile

VR application can have referred to Figure 3.2. The mobile VR is developed

focusing on artifacts learning content.

Figure 3.2: Content of Mobile VR

26

3.2.2 Design Process

Design phase is the second phase in making Virtual Cars Showroom

in ADDIE model. The design phase should be systematic and specific.

Systematic means a logical, orderly method of identifying, developing and

evaluating a set of planned strategies targeted for attaining the project’s goals.

Specific means each element of the instructional design plan needs to be

executed with attention to details. In these phases, storyboard and prototype

making. Storyboarding is also a part of multimedia design process. The

storyboard can show the look and feel of the application that will be

developed. The phase is implemented after phase 1 is completed and become

“blueprint” or backbone of planning in the process of designing. In design

phase, navigation chart and storyboard were developed.

3.2.2.1 Storyboard

Storyboard is also part of the design process of multimedia.

The storyboard shows the application's feel and look that will be

developed. Figures 3.3, 3.4, 3.5, 3.6, 3.7 below display some of the

storyboard.

29

3.2.3 Development Process

The phase of development is where developers create and organize the

product assets created during the design phase. Programmers are focused on

technology development and/or integration. Testers execute procedures for

debugging. Depending on any feedback given, the project is reviewed and

revised. In this phase, Unity 3D software used to develop Virtual Cars

Showroom application and animated 3D character. Maya 2020 software also

used in this phase to create 3D model in Virtual Cars Showroom.

30

3.2.4 Implementation Process

The phase of implementation is a test phase. The supervisor and friend

test completed application and give response. The aim of testing is to identify

the weakness and detect any unrecognized errors during the authoring

process. The supervisor openly commented and criticized during the test for

making improvements, and any mistakes can be corrected. This is to ensure

the project is easy to use and to run accordingly. User test run is sent a demo

version for alpha and testers to ensure that the project meets their requirements

before presenting the final product. Criticisms and constructive feedback are

taken into account to be implemented later on.

31

3.2.5 Evaluate Process

The final phase, which is the evaluation phase. If the design is found

to be incomplete or unsatisfactory, improvements or addition will be made

based on the user's feedback, response in presentation, and commented from

supervisor. For the first time in this iteration, only the prototype with the base

function is generated most of the time and decisions on further iteration.

Further iteration of the verification phases and changes will take place to add

features such as the different viewpoint, the advanced way of Google

Cardboard, and so on. The iteration will not stop until the application is

perfect or the application will satisfy the user.

3.3 Framework

The project conducted on the framework of the structure and system

flow to achieve the project objective that can be successfully accomplished

by analyze Virtual Cars Showroom using Google Cardboard. The

requirement analysis should be conducted in order to run the project and a

project framework can be created to see and understand the process flow. The

methodology framework is described in Figure 3.9, which is divided to user,

Google Cardboard and Virtual Cars Showroom application. To play this

application, user should use google cardboard or VR box to connect to the

32

application. Then, the application will provide a virtual reality view in Google

Cardboard and the user will feel immersed in the environment.

background and create scripts or documents

related to application. Also used for on the

go coding and 3D modelling.

External Hard Disk

To backup all project data.

Headphones

Used for development and test runs of the

projects as well as used for the finished

project to amplify immersion.

35

Google Cardboard

Used for test runs and overall final product.

Mobile Phone

To run and test the application.

Mouse

Mouse is used during coding and 3D

modelling process.

3.5 Technique/Method

The technique that use in this project is point of gaze. The point of gaze

in the user-computer interaction is recorded and used in real time as an input.

In this field researchers are developing more efficient and novel human-

computer interfaces to help users with and without disabilities. Person's point

of gaze can be used in a variety of ways to control user interfaces, alone or in

combination with other types of input such as a mouse, keyboard, sensor, or

other devices. A major field of gaze interaction research is discovering more

36

efficient and innovative ways to facilitate interaction between

humans and computers for users with disabilities who can only use their

eyes for feedback. Certain gaze interaction research focuses on the

general use of real- time interactions. Figure 3.10 is the example of the

point of gaze method.
