3 3 The System Device To create a system that is lightweight and intuitive enough to use without the hinderance of the user s ability to operate and carry other tools and equipment, and to use at a moment s notice, we will implement the use of a modern smart watch. fig1. concept GUI on the Moto 360 on its charging deck A bright LCD display will be visible in rooms with low to no levels of light. A Smart Watch, along with a paired Android phone will provide the sensors needed for the relevant information for tracking and logging the vitals signs and precise locations of firefighters. The wide array of APIs provided by a smart watch and Android phone will provide multiple ways of tracking the position of a firefighter that may or may not have a network connection. Such as GPS, Wifi, Heart Rate sensor, and pedometers. Using Android will make the entire system modular. Android is a strong standard so that the software can be paired among many current and future devices that are also cheap.

4 4 GUI The GUI was designed to be simplistic with minimal colors and clutter. Big texts display only the most relevant and important information that can easily be glanced at, and a distress button ia big enough to be used by a disoriented firefighter in stressful situations. Calm State Distress State fig2. Concept GUI. GUI on the right is in calm state and distress state on the right, changing from green to red A clear color change from a calm green to a vibrant red will display when the firefighter is experiencing a heart attack, or when they hit the distress button. This clear indication will let the user, and other firefighters know that immediate help and the evacuation of the user is imperative. The longitude and latitude of the firefighter will be tracked by GPS in the paired phone. Firefighters can then relay their location to other firefighter s where they can use their own location as a reference.

7 7 The Hardware Part Description: Description Manufacturer Part # Price Moto 360 Motorola, Inc 00418NARTL $ Nexus 5 LG Corporation D820 $ Dell Inspiron 14 Dell Inc. i blk $249 table1. parts list for Life Monitor Because of the advantages of using the Android platform, as long as the hardware and software meets the requirements these parts are interchangeable. However, the Moto 360 is the only part that must be used because of its unique heart rate sensor API. Life Monitor can be easily implemented for future smart watches. Any android phone with software greater than 4.3 (Jellybean) can be used. This requirement must be used in order to download the Android Wearable app to pair the devices. We chose the Nexus 5, however cheaper alternatives can be used. The laptop is our main development unit and will not be required for the deployment of Life Monitor. Once the software is packaged, it will be able to run on the phone and Moto 360 independently. To develop the software however, a laptop must be able to run Windows 8 sufficiently to run the Android Studio and Life Monitor software. The Android phone will be the vital part of Life Monitor as it is the central hub of the system. The phone is responsible for saving the logs of the heart rate from the smartwatch, as well as gathering GPS and Wifi information. The moto 360 provides the front end of the system to be worn by the user. It displays all of the relevant information, as well as a manual distress button. The watch also provides the heart rate sensor to be transmitted to the screen.

9 9 fig7. Moto360 hardware flowchart How to build: Android phone: 1. Go to android phone system setting and open developer option. if developer option is not there, go to about phone and tap build 7 times. 2. Check the USB debugging option and click Ok. 3. Connect the android phone to computer through USB 4. Choose to connect as camera if asked 5. Go to notification and click connect as camera and select the PTP option. 6. Open the Bluetooth on the phone 7. Go to play store and search for android wear. 8. Download and install android wear. 9. Open android wear and looking for the moto 360 in the list appear and click connect/pair. 10. After connected, click the moto 360 and search for the application received from laptop. 11. Install the application to moto Receive update from moto 360 and receive a warning if watch detect heart attack.

10 10 Computer: 1. Go to 2. Download and install the client you download. 3. In Android Studio, click SDK Manager in the tools->android. 4. Open the Tools directory and select: Android SDK Tools, Android SDK Platform-tools, Android SDK Build-tools (highest version) 5. Open the Android 5.1 folder (the latest version) and select: SDK Platform, ARM EABI v7a System Image 6. Open the Extras directory and select: Android Support Repository, Android Support Library, Google Repository, Google Play services, Google USB Driver 7. Click Install packages. 8. In the next window, double-click on the left to accept the license agreement for all packages. 9. Click Install. 10. Go to device manager and find your android phone in other devices tab 11. Right click the choose update driver software and choose browse my computer for driver and choose the driver location you install in step 6 and select include sub-folder. If your device doesn t support android phone, go to and download the android phone driver you have and install the driver. 12. Open the completed application(source code) in the file tab 13. Press the run and select your android phone/watch in the window appear. 14. Your android phone/watch should have the application launch on the screen. Moto 360: 1. Pair/connect with the android phone 2. Received the application download from the android phone 3. Launch the application 4. Record and update the heart rate 5. If heart attack detected or help button is pressed, send warning to the phone.

11 11 The Software login fig8. software diagram for the Life Monitor System. Blue marks moto 360 and green for the Android phone LifeMonitor starts at the login screen on the Android phone. The user inputs their name, rank (i.e sergeant), and the other firefighter s cell phone number that can be used for panic SMS messages. These variables are sent and set in the phone and Moto 360. The Android phone uses this input to identify who it s logging, and the name will be displayed on the Moto 360 so other firefighter s can identify the user. activeactivity The active activity is the main screen (the concept shown before) that displays all of the up to date information on the firefighter s vital signs, as well as the distress button. This class will run on the Moto 360, and will call the Heart Rate Sensor API, and receive the GPS signals from the phone. The text will constantly be updated

12 12 msensormanager The motorola API responsible for gathering the Heart Rate on the moto 360. This API is manufacturer dependent. phone The main class for the paired Android phone. It first recieves the user s input and sets their name and rank, then begins logging their heart rate signs from the moto 360. It also constantly sends up to date GPS information to the moto 360 LocationManager The GPS API for the Android phone. It provides the longitude and latitude values, and also the strongest provider. This API is standard among Android phones and can be implemented across many platforms. Most of the system relies on the software which mainly gathers information, and displays that to the user. In the backend, the software is mainly calling the APIs for updated information, and it logs the heart rate data gathered from the moto 360. Life Monitor continues running until the user stops the program.

13 13 Running the System Smart Guide 1. Touch the Handi icon to launch the phone app 2. The user will be prompted to enter their name, rank, and the phone numbers of the firefighter in their team.

14 14 3. Once logged in, the Wear companion app will start automatically 3. The watch will now continuously track the heart rate of the user and broadcast it to the phone via bluetooth. 4. If the phone app detects an anomaly in the user s BPM, it will trigger the Alert State on the watch and send a warning and the user s GPS location to the firefighters

15 5. The user can manually engage the Alert State on the watch by pressing the HELP button on the UI 15
