ABSTRACT
In this study, the application, Into the Campus, was used as a visual tool in advocating the virtual and 3D technology
to allow its user to experience the environment of La Verdad Christian College Apalit chapter anywhere they
want. The researchers used Google Sketchup, to create the 3D objects and buildings of the school. Unity 3D was
used to merge the 3D objects and create the Virtual Tour and 3D Map feature of the application which shows the
different parts of the school including its facilities and rooms, and also some information about the different objects
inside the campus. The respondents of the survey conducted were from La Verdad students and non-students to
measure the whole usability, functionality and accuracy of the mobile application. In the final results, it was shown
that in the overall responses, the application would greatly help students, applicants and their parents to be
familiarized with the appearance of the school and know the different basic application process of the school even
before they visit the school personally which would help them make their application process faster, and convenient.
This would also help the applicants with their decision making on applying to the school.
KEYWORDS Virtual Tour, 3D Map, Android, Mobile Application, Unity 3D
INTRODUCTION
Choosing where to attend college is a complex decision-making process for students [1]. The introduction
of Virtual Tours and Interactive 3D map technology have greatly helped in creating solutions to problems that
includes students having slow admission process of the school due to the unfamiliarity of the place and insufficient
information about the whole process of the admission itself.
The project aimed to serve as a guide to familiarize the people including the students and their parents or guardians
on what does the school looks like without spending too much time and money. It would let others experience the
environment and the atmosphere of the school by showing them a detailed virtual representation of the school
chapter itself. “Almost all schools have realized that they have to have a virtual presence online”. Students who visit
schools, even virtually, “are better informed students, so if they decide to apply, they will actually be a much b etter
fit,” [2]. The purpose of the project is to create an application that will be able to properly int egrate the use of the
advancement of technology to help the incoming students including their parents to be properly guided on the things
that they must know before and after they enter La Verdad Christian College.
In the most recent statistics by Commission on Higher Education (CHED) last December 2018, only seven (7) out of
199 registered colleges and universities offer a campus map on their school website. Five (5) out of 199 of them
offers Image-Stitching panoramic images of the campus, 37 out of 199 colleges have video-based Virtual Tour and
Seven (7) out of 199 colleges have photo slideshow on their website.

Objectives
The general objective of the project is to make an interactive virtual tour of the campus to showcase the whole
architecture of the school. Second is to minimize the inconvenience of new student applicants and parents in the
application process.
For the specific objectives of the research:
To create a 3D Representation of the different buildings and structures of LVCC Apalit using unity 3D and
Google Sketchup Applications.
To deploy the project as an android application and install it to compatible android devices.
To Prove if the application will be able to help minimize the inconvenience of students and parents in the
application process
Conceptual Framework
For the researchers to create the application, they have gathered first some information and data about the
different process and policies of the school through interviews. Different photos of the schools infrastructures and
facilities were also taken for the reference during the creation of the 3D objects. Navigational Map of the campus
grounds were also borrowed from the schools engineer to serve as a guide for the 3D Map feature of the
application.
Figure 1. Conceptual Framework of the Project
Translating the photos taken into 3D object was one of the process that the developers has done to create the
application. After the creation of the 3D objects, it will be imported to other application for the creation of the
virtual environment. Then once the application is ready to be used, it will be rendered as an Android Package Kit to
be deployed in Android devices.

LITERATURE REVIEW
Usage and Importance of Interactive Maps and Virtual Tours for Schools and Universities.
The study entitled as Web Interactive Campus Map is a Web Based application created for Mindanao
University of Science and Technology (MUST). The developers of the project have used the availability of Google
Map API to develop the plan and the authors made use of custom overlay functions to achieve th e possibility in
adding additional functionalities of the campus map [3]. Abi Mandelbaum, whose company, YouVisit, creates a
virtual walking tours for universities, said that about 80% of different ap plican ts wo u ld visit no more than f o ur
college campuses around their area physically. These students have indicated that having a campus visit was a
significant factor that affects their decision-making [4]. Having a virtual tour of the campus makes it stand out
among other universities that don’t have virtual campus tour and students may promote or share their experien ce in
using your virtual campus tour to their friends, parents, and relatives to help in deciding if they want to enroll to that
university [5].
METHODOLOGY
Development Requirements
Hardware: Unity 3D, which is the leading platform in the developments of the application requires a laptop or a
desktop that has a minimum specification of two (2) Gigabytes of Random-Access Memory (RAM) and a Hard Disk
Drive (HDD) with at least 500 Gigabyte of memory [7]. Listed below are the major software and its versions that
have been used during the development process of the application. These software requirements include the 3D
engine and the programming language used is the coding process.

During the benchmarking process, smartphones that has an operating system of android 4.0 and below does allow
the application to be installed. However, when the user starts the application, it only shows black screen and the
whole application wont load. Also, even if the smartphone has high-end specs, and can run the application
smoothly if it has low available memory, the application will crash during the loading of the virtual tour. But freeing
up more space will fix the issue. The most recent render of the application will take up to 408 Megabytes of memory
upon installation and will need at least 100 MB more memory for it to extract the resources during its loading phase
in different scenes of the App.
RESULTS
The proponents of the project surveyed to evaluate the usability, accuracy, and functionality of the mobile
application and used ISO/IEC 9126 to measure and evaluate to the overall software quality. Purposive Sampling was
used to obtain good quality sample and information from random people.
The respondents are composed of 30 students from La Verdad, 16 students from other schools, nine non-student, 4
LVCC Alumni and one parent. The results of the survey responses are illustrated below.

CONCLUSIONS/RECOMMENDATIONS
During the deployment of Into the Campus application to other devices, the users have encountered some problems,
but with the efforts of the proponents to minimize the errors and lapses, these issues were handled successfully.
With the help of the participants in the survey and advisers of the program, the proponents got the results and
concluded the following
The application would greatly help ease the inconvenience of the applicant during the application process.
The application will be helpful in the decision-making of the incoming students.
The visitors will become more informed and oriented about what should they know before entering the
campus.
The users will gain bits of wisdom of some things about La Verdad Christian College.
The application will be able to advertise the school in the future for it to be known in greater parts of the
country.
Some of the recommendations from the panels includes the addition of the mini map in the Virtual Tour part of the
application, improvement of the collision detection, make the main character wear a uniform in the Virtual Tour,
panning in the 3D Map and flexibility of the App to be deployed in iOS for Apple devices. These recommendations
are for the future development of the project that will greatly improve the performance and the potenti al of the
mobile application.
