This document proposes a real-time tracking system using Android GPS and GPRS to locate patients suffering from Alzheimer's disease. The system consists of two modules - a caregiver module and a patient module. The patient module uses the device's GPS to continuously monitor and report the patient's location to the caregiver module. The caregiver module displays the patient's location on a map and allows caregivers to track the patient in real-time. The system is designed to provide a low-cost solution to locate Alzheimer's patients and help caregivers monitor them.

2. INTRODUCTION
• Alzheimer’s disease (AD) is a degenerative disease which is growing widely.
• There are various factors which contribute to this disease such as genetic ,
cholesterol, down syndrome etc.
• It is most common in the elderly patients and about 10 percent of population in
u.S above 60 years of age are affected by this disease.
• With this stated, the cost to cure ad is also very high, hence it has now become
important to come up with a cost effective solution .

3.  Symptoms:
Poor Judgment, Misplacing Things, impairment of movements, problem with verbal
communication, abnormal moods and loss of memory.
 The loss of memory makes the person forget from where they have come .
 Finding the where how of such a person becomes a difficult task.
 The tracking system would help the user to find effective and real time location of the
concerned person with the use of geographic
positions from the Global Positioning Satellites.

4. PURPOSE
 There are similar products available today which can be used to trace the
location.
 The purpose of this project is to integrate the Global Positioning System
and Global System for Mobile Communication technology for real time
people tracking using Maps.
 This methodology is cost effective as compared to the treatments and
solutions that exist.
 It is also time effective and secured too.

5. PROPOSED METHODOLOGY
• The proposed system consists of two modules: The caregiver module and the patient module.
• This system uses GPS and GSM technology. This is an embedded application, which will
continuously monitor a patient from its source and reports the location of patient as and when
required.
• The basic requirements are :
• A. Windows 7/8/10 with i5 and i7 processor
• Java JDK 1.5.0 +
• Android Studio IDE
• Android SDK
• Android Emulator
• Android Device with in-built GPS system and Android 4.3 gingerbread and later OS

6. DESIGN PROCESS
• The design process starts by creating a user interface form.
• The main form would display the current position.
• The form also contains a timer control which is used to automatically update the coordinate
information that is received from GPRS modem in every short interval of time.
• The block diagram for the Patient Module and care given module are as shown below:

Care Giver Module

8. DESIGN TESTING
• The embedded system is divided
into two parts, which are the
Caregiver Module part and the
Patient Module part. For tracking
part, the embedded system is
equipped with GPS.
• Both of the coding for Caregiver
Module part and the Patient Module
part is then tested to make sure that
they meet the specification.
• When both of the coding fulfills the
specification, the whole system is
being tested to ensure it works
properly.

9. LAYERED ARCHITECTURE
Client side:
 User Interface - This layer provides the graphical interface to
user within the application.
 Android API -Whole system is built on Android API along with
other API we are interested in Location Service and Google
Maps API.
Server side
 Logic Layer - This layer controls the whole logic behind the
location storing. The logic layer contains all the components
related to Caregiver and Patient Module
 Data Access Layer - Data access layer provides simplified
access to data stored in persistent storage such as an entity-
relational database.
 Database - Database will be implemented in SQL and will
reside in azure web server this would Implemented using
Microsoft azure Mobile services

10. ALGORITHM FOR PATIENT MODULE
 Check GPS: Firstly we will check that GPS is enabled if not enabled we will ask user to enable
GPS to start tracking Patient.
 Start tracking Patient Location: We can track Patient location using GPS system in android device
and Location Manager Class. This Class provide Longitude and Latitude in Real time.

11. PATIENT MODULE CONT…
 Location Manager: To access real time location of patient module location manager class provides
access to location service. These services allow applications to obtain periodic updates of the
device's geographical location.
 Location Listener: This class receives update from location manager class when location changes.
The following methods are called when location listener instance is registered with location
Manager.
 Database connection: We have created a SQL database in azure mobile cloud service to store our
longitude and latitude in database every 5 seconds.

12. PATIENT MODULE CONT…

13. ALGORITHM FOR CAREGIVER MODULE
 Google Map API: Use Google Map API to implement map activity in android application
 Update Map: Now as the basic maps are loaded we will update the marker in map to point to
real time patient location.
 Update location frequency : We can set how frequently we want location to be traced.
 Asynchronous update: Update Map marker and location in background thread asynchronously.

16. Caregiver Application

17. FUTURE SCOPE
 There is wide range of improvements that can be made to this application which are
namely as follows:
 An alarm clock beeping mechanism in care given module when patient goes out of
boundary.
 A reminder note in patient module about his/her address if he feels he gets lost.
 A warning beep in patient’s phone when he/she tries to go out of the range which is
decide by the care giver.

18. CONCLUSION
 Tracking module is used to track the user location while the displaying module is
used to plot the user location on Google Maps.
 This project will be an cost-effective and easy to use solution to tracking the patient
of Alzheimer’s, Patient tracking module needs GPS to determine the patient location
and tracking to which it is attached and using GSM modem, this due to its low cost,
it is very easy to integrate into other technology.
