List of Definitions

Alzheimer - A progressive form of presenile dementia that is similar to senile dementia except that it usually starts in the 40s or 50s; first symptoms are impaired memory which is followed by impaired thought and speech and finally complete helplessness

Application Programming Interface(API) - The interface that a computer system, library or application provides in order to allow requests for service to be made of it by other computer programs, and/or to allow data to be exchanged between them.

J2ME - Java Micro Edition (Java ME or as it used to be referred to J2ME), is a runtime and collection of Java APIs for the development of software for resource constrained devices such as PDAs, cell phones and other consumer appliances.

User Datagram Protocol (UDP) - is one of the core protocols of the Internet protocol suite. Using UDP, programs on networked computers can send short messages sometimes known as datagrams to one another.

Structured Query Language (SQL) - A popular computer language used to create, modify, retrieve and manipulate data from relational database management systems. .

Project Overview

Problem Statement

Alzheimer’s disease currently affect a large population

Patient cannot be immediately placed in a care facility

A close family member stays in close contact in order to take care of them

Situation can become extremely stressful for the caregiver

Solution

General Solution-Approach

The proposed solution includes an easy to use specialized communication system consisting of :

A wall mounted home display unit for the patient A caregiver’s mobile communication device

Helps the caregiver in carrying out normal routine work and take care of the patient at the same time

Operating Environment

Home display unit shall only be operated with in a room Patient’s room shall have internet connectivity Communication Device shall be within coverage area of

the cellular service provider Room Temperature for home display unit shall remain

between 35 to 75 º F Caregiver communication device shall be operated between

30 to 100 º F

Intended User and Uses

Intended User Moderate Alzheimer’s patients and Caregivers Doctors Elderly people Handicapped people Families Business people

Intended Uses Communication between Alzheimer’s patient and caregiver Communication device between doctor and his several patients Replacing existing home phones Providing message service Can be used in offices

Assumptions

Low or Moderate level Alzheimer’s Patient Caregiver has knowledge about basic cell phone usage Caregiver has knowledge about basic computer usage Caregiver communication device should be Java enabled

to run J2ME software Caregiver communication device should have data

enabled cell phone plan (GPRS or Internet plan) Home display unit should have touch screen capability

Limitations

Functionality vs. ease of use for Alzheimer’s patient Skype account & required balance to make &

receive calls System designed primarily for GSM based networks

End Product

A communication system consisting of

Home display unit Easy to Use GUI

Push to talk Capability

Caregiver Communication Device

Push to talk Capability Communicate with Home Display Unit Remotely

Project Definition

The Home Display Unit

Easy to use graphical user

interface developed in Visual

C ++ .NET Easy to read screen to display

messages from caregiver Uses Skype API functions for

VoIP Contains easy buttons with

pictures to call care givers or

family members Appointment Calendar Phone Dialer

Server

The server will route data between home unit and care giver communication device.

The server shall uses SQL for database.

The server shall keep database for all message history and appointment calendar

Communication Device

Allows care giver to talk with home

display unit. Send text messages remotely to

home display unit. Send appointments remotely to

home display unit Synchronizes with database and

ability to view appointments

Research Activities

Technological Research Researched various options for the system

Programming Languages & Environments J2ME J2ME Polish (.XML, CSS)

Process Team members created mini projects to learn

the language

The Home Display Unit GUI

CALL button

The purpose of the CALL buttons are for the patient to easily call caregiver

Runs the appropriate API function to make or receive call

Volume Control Button

The volume control is in the form of scroll bar on the GUI for ease of access

Has mute function

Options Button

Only for the care giver Gives the flexibility to

the caregiver to

update the cell number and other

contacts Allows to change

server used.

Server and Database

Home Unit Cell Phone

Server

Lay out

Database

Database will store the data between the home unit and cell phone

New user will put the information like username, password, name, phone number

Message – Sending and getting message will be saved in database

Log on, log off, get status

Implementation Activities

Home Unit Implementation

The GUI is just a windows forms application that uses event handlers to call members from the Skype.dll

Microsoft Provided Class for Skype API Created in Visual Studio .NET 2005

Home Display Unit

Changes GUI layout Message Display Format Capable of Video Messaging but removed Added other functionality

Communication Device

Used J2ME for software development Enhancements made with J2ME Polish Enhanced functionality

View/Add appointments

Server

Coded in Java Multi Threaded Added GUI for style

Testing Activities

Testing Activities

Testing Considerations Communications device testing using emulator on PC Home Unit testing by using its interface to communicate

with team members personal mobile phones Server testing by writing test code to act as home unit

and communications device Set up all applications on home unit, server, and

communications device and use device interfaces to

ensure functionality

Communications Device Testing

Wireless Toolkit Emulator Test Phone software without

installing software on the phone

Integration Testing Team member used cell phone

to communicate with Home Unit

Server Testing

Tested during testing of other units Central point of data communication.

Home Display Unit Testing

Team member sits at Home Unit and pushes

buttons Verify Data communication via server and

database lookups Test GUI layout on others outside project
