Basic System Diagram

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

Approach Considered and Used (3/3)  Database  SQL used and only one considered  Known by team members  Well documented on the web  Works in Java

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

Design Activities

Communication device flow chart

J2ME Polish  Used to enhance the visual element in the GUI for the communication device GUI before J2ME polish GUI after J2ME polish

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 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 in stalling 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
