1.0. INTRODUCTION

The Public Health Monitoring System for Filipino Children is a telemedicine system that aims to fulfill the need

for children to undergo routine wellness checks with a doctor in communities that may not have accessible,

affordable or quality healthcare. It serves as a go between patients and doctors that cannot find the time to

meet for a check up. Basically this system allows a software with an assistant, not necessarily medically

trained personnel, to perform the basic health monitoring activities for children and store these results for

doctors to view and diagnose at a later date.

The system consists of three mobile applications developed for Android tablets: GeeBee for monitoring and

consultation activities. GeeBeeCapture for calculation of height and weight via image processing. GeeBeeView

for displaying the collected data. The target users of GeeBee and GeeBeeCapture are children aged 6 to 14

years old and their assistants while GeeBeeView are for doctors and medical personnel or authorities planning

for children's healthcare.

1.2. INSTALLATION

There are no prerequisite requirements for the installation of the applications for this system however these

applications must be installed on Android tablets. To install the mobile applications under this system, simply

use the apk provided.

Note: When installing GeeBee



,GeeBeeCapture will also be installed because they have interrelational

functions. GeeBeeView

 can either be installed on the same tablet or separately from GeeBee



This software is originally intended be a module or an additional part to the existing “GeeBee” app.It comes

prepackaged already with the original application, “GeeBee” . Hence, installation of Geebee will have such

software to be installed as well. To install the required systems, simply tap install apk when prompted. The

android device will automatically install the software.

Then follow the dialog boxes that pops out after pressing. You have to select what region, next button. Then

select what province then press next button. Then select what municipality the school resides in, then press

next button. Finally, you input the name of the school in the text box dialog then press add. The school should

2.3 Syncing to Remote Database

To sync the collected data of the app, one just has to simply press the ‘Sync Data’ Button on the left most

corner of the Activity.

Once the user presses the ‘Sync Data’ Button, two things can happen the sync fails or it pushes through. Once

the sync is done, the user is notified via toast that it has completed its upload. If it does not the user will also be

notified by a no internet connection error or other errors.

3.0. GEEBEECAPTURE

This application is responsible for computing the height and weight of the person. Limitations of this module

are as follows: a reference object specifically a ruler must be used that is sticked to the wall beside the person

whose image will be captured. The person must not be blocking the said reference object and must be in

upright or perpendicular to the ground.
