CHAPTER 1

INTRODUCTION

1.1 PROJECT BACKGROUND

Virtual reality is a technology that allows users to interact with the

environment that is simulated by the computer. By looking at the screen in front of them,

users can interact with the 3D world. Virtual reality are the combination of video and

audio ,it give experiences that make users feel the real world sensation. Virtual reality

usefulness in many fields and as a result of the attention given to it by the media. This

trend is expected to continue in the future with the advancement of technology in areas

like computer graphics, computer vision, controls, image processing, and other

technology-affiliated components. The project to be developed is an application to learn

about solar systems, named " Virtual Reality Solar System ". The concept of virtual

reality used is expected to help students in studying solar systems in 3 dimensions, as if

2

they were context of real space situation. These applications employ interaction as a

means of communicating information to the general public in new and exciting ways.

1.2 PROBLEM STATEMENT

2.2 VR PLATFORM

In virtual reality, the platform used in the production of an application depends

on the selection made before the builder. In this application I use VR Headset as the

main platform. VR Headset is a virtual reality (VR) platform developed for is a head-

mounted device that provides virtual reality for the wearer. Virtual reality (VR)

headsets are widely used with video games but they are also used in other applications,

including simulators and trainers. Users can either build their own viewer from simple,

low-cost components using specifications published by Google, or purchase a pre-

manufactured one. To use the platform, users run the VR Headset compatible

applications on their phone, place the phone into the back of the viewer, and view

content through the lenses.

Every phases of this methodology will be explained.

17

3.2 ADDIE

In this project, the most suitable methodology that can be used to develop

mobile VR application is ADDIE. The ADDIE model is the generic process

traditionally used by instructional designers and training developers. Addie is an

acronym for the five stages of a development process that stand from Analysis, Design,

Development, Implementation and Evaluation as illustrated in the Figure 3.1. The

ADDIE model relies on each stage being done in the given order but with a focus on

reflection and interation. The model gives a streamlined, focused approach that provides

feedback for continuous improvement.

Figure 3.1 : ADDIE MODEL

3.2.1 ANALYSIS PHASE

In the analysis phase, the designer identifies the learning problem, the goals

and objectives, the user’s needs, existing knowledge, and any other relevant

18

characteristics. Analysis also considers the learning environment, any constraints, the

delivery options, and the timeline for the project. The analysis is also carried out by

doing market survey on existing product. So, the weakness of the existing product can

be identified. The comparison of existing product as show in Table 3.1.

3.2.3 DEVELOPMENT PHASES

The development phase is where the developers create and assemble the

content assets that were created in the design phase. Multimedia applications should be

used based on the designs established through the design phase. The development of

this design refers to the process of software development using a variety of existing

applications such as programming applications, authoring, video, animation and so on.

At this phase, have three stages include pre-production, production and post production.

3.2.4 IMPLEMENTION

During the implementation phase, a procedure for training the facilitators and

the learners is developed. The facilitators’ training should cover the course curriculum,

learning outcomes, method of delivery, and testing procedures. Preparation of the

learners include training them on new tools (software or hardware), student registration.

This is also the phase where the project manager ensures that the books, hands on

23

equipment, tools, CD-ROMs and software are in place, and that the learning application

or Web site is functional.

3.2.4.1 Test run

This is when the developer test runs the project by herself. This is to

ensure that the project can be used and is running accordingly.

3.2.4.2 User Test Run

Before presenting the final product, a demo version is given to alpha

and beta testers to ensure that the project is meeting their criteria.

Criticisms and constructive feedback are taken into account to be

implemented later on.

3.2.5 EVALUATE PROCESS

The evaluation phase is which the project is being subjected to meticulous final

testing regarding the what, how, why, when of the things that were accomplished of the

entire project. This phase can be broken down into two parts: Formative and Summative.

The initial evaluation actually happens during the development stage. The Formative

phase happens while students are conducting the study, while the Summative portion

occurs at the end of the program. The main goal of the evaluation stage is to determine

if the goals have been met, and to establish what will be required moving forward in

order to further the efficiency and success rate of the project.

CHAPTER 5

5.1 INTRODUCTION

In this chapter, the contribution of ‘Virtual Reality Solar System’, problem

and limitation during project development as well as future work to improve Sistem

Solar will be discussed.

5.2 PROJECT CONTRIBUTION

Virtual Reality Solar System developed based on the ADDIE method

mainly aim to help users learning about the planet in a new interactive environment.

Meanwhile, the other aim is users also can learning about the VR technology in

their life. By using this application, users can be opportunities in learning about

the planet with more effective and efficient due to the interactive and new

technology way.

Furthermore, it is very convenience since it is an android application and

can be accessed by user everywhere because it did not use internet connection.

Moreover, the users can experiences play with the virtual reality and learn about

it more.

5.3 PROBLEM AND LIMITATION

The problem and limitation during the project development are the

colliders is not functioning well as expected. This has caused due to lacking of

knowledge in this field also make the project development quite harder and not

works well.

5.4 FUTURE WORK

Virtual Reality Solar System still needs to improvement a lot from time to

time. Since this application just focus to the planet, so developer can add more object

that exist in the space like Meteoroid, Comet, Asteroid, Moon and anything else that

exist in the space. So users can learn more about the space. In addition, this

application can build with more interactive such as game or quiz so that users can

know their skills level and knowledge. Lastly, this application can also built with new

platform such as Oculus Rift. So user will have more experiences in virtual reality

with more realistic environment.
