Agenda

• Introduction and Problem Statement – Shariq• Functional Requirements and Phone Details - Andrew• Technical Considerations - Kim• Home Display Unit GUI Details - Ahad• Home Unit Coding Details - Shariq

Problem Statement• Alzheimer’s disease and dementia currently affect a large and

growing segment of the population.

• Most people who are initially diagnosed with these conditions cannot be immediately placed in a care facility.

• They cannot live on their own; a close family member typically stays in close contact in order to take care of them.

• This situation can become extremely stressful for both the caregiver and the cared-for due to the constant presence required to ensure the safety of the cared-for person.

• The proposed solution includes an easy to use communication system that will help both the patient and caregiver to communicate with each other.

• They can communicate via voice, video and text.

Intended Users & Uses

Intended Users• Alzheimer’s patients

and Caregivers • Elderly people• Handicapped people• Families

Intended Uses• Communication

between Alzheimer’s patient and caregiver

• Replacing existing home phones

• Providing message service

• Can be used in offices

Home Display Unit• Home Display Unit is a wall mounted device which has

the following functionalities:• The home display unit shall have one button push to talk

capability and the button will be on the lower corner of the screen.

• The home display unit shall have easy to use graphical user interface (GUI) for the patient.

• The home display unit shall have data transfer capability with the caregiver’s communication device.

• The home display unit shall have built-in mic. and speaker capabilities with volume control.

Functional Requirements

Communication Device• Communication device is for the caregiver which

has the following functionalities:• Communication device used is a cell phone.• The communication device shall have existing

enabled cellular service.• The communication device shall have a

programmable GUI.• The communication device shall have data

transfer capability for voice and data communication (up to several messages).

Technical ConsiderationsDonghoo Kim

Touch screen home device

• Convertible Laptop XP based (Gateway® CX200S)• The least expensive.• Allows for a wide array of software applications to be run

on this system. • There is a keyboard and mouse on the unit .• A wide variety of extras such as DVD players and

expandable hard drives. • Offers more options than this project requires .

Phones Selected: A1000reasons for selection

• Runs the Symbian operating system. • It seems like future phones will start to use this OS as

well.

• Was selected as a test phone because of its similar look

and layout of the phone.

The Home Display Unit GUIAhad Mir

The Home Display Unit GUI

• Easy to use - Touch Screen • Main GUI made by Visual C ++ • Contains different buttons to control the communication

process• Buttons connected at backend to SKYPE API functions• Contains a single button to make or receive calls

CALL button

• The purpose of the CALL button is to make and receive calls for the patient

• Runs the appropriate API function to make or receive call

Volume Control Button

• The volume control is in the form of scroll bar for the ease of use for normal people

• Has mute function

Voice Mail Button

• The system allows the caregiver/any caller to record voice mails

• Recorded messages are retrievable through this button

Customize Button

• Only for the care giver• Gives the flexibility to

the caregiver to

update the cell number

• Allows to update IP Address

Add Ons

• Different functions – can be added using API functions• Call Scheduling• Caller ID• Address Book• Things to Remember• Morning Alarm

Coding Details for Display UnitShariq Tehsin

Display Device Software

• The display device software uses the Skype API• The Skype API passes commands in simple text

messages between Skype and client applications and devices

• The Skype API has two main components; the Skype phone API and the Skype access API.

• The display device software uses the Skype access API.

Skype Access API

• The Skype access API enables external applications to control certain Skype functions,

• For example to place a call

Characteristics of Skype API

• All actions performed using the API are mirrored on the Skype client

• All times and dates in the API are in UTC (Coordinated Universal Time)

• Multiple applications can use the Skype access API at the same time.

• Transmission over the API is in UTF-8 encoding.

Initialization

• Use the RegisterWindowMessage method to register• To initiate communication, a client application broadcasts

the SkypeControlAPIDiscover message• Skype responds with a SkypeControlAPIAttach message

Communication between Skype and Client program

• The client application issues a command to control Skype

• In reply to some commands, Skype returns a synchronous response

• Skype objects are application, call, chat, chat message, profile, user, and voicemail.

Commands

• CALL command (Use the CALL command to make a call)

• Set CALL INPROGRESS command (Use the SET CALL INPROGRESS command to take an incoming call)

• SET CALL FINISHED command (Use the SET CALL FINISHED command to end a call)

• SET CALL ONHOLD command (Use the SET CALL ONHOLD command to place a call on hold)

Message Receive Code

The display device software uses the sockets to receive the text message
