2. System Architecture
In SmartWatch, the background service measures
the x-axis data of accelerometer sensor
and the value of heart rate sensor in real time.
Through the smoking detection algorithm using the sensor value,
the corresponding time and place determined to be smoking is
transmitted to the mobile device via Bluetooth.
On the mobile device, the smart watch displays the smoking time
and place by date based on the smoker's information transmitted via Bluetooth,
and displays the amount that can be saved according to the user's smoking amount.
It also provides community and VS mode.
The database uses Google Firebase. Thus synchronizing with the mobile device in real time.
It manages individual user data through Google login,
and additionally manages and stores data for community and VS mode.
