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

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).

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
