To design a device prototype which will monitor the build-up of fatigue in drivers and accordingly take steps so that there is no loss of control over the vehicle due to the driver falling asleep at the wheels. This project’s purpose is to review published journals regarding: a) the scale of the sleep related road accident problem b) to come up with solutions that minimise accidents due to the driver sleeping off at the wheel and design a suitable prototype which acts as a detection and alert system in real time.
To Extract health-data from a wearable device, specifically the sleep data (pre-made by the “Fitbit API”).
- To process this data using a microcontroller and use the processed data to control the speed of a stepper motor, which is, analogous to the speed of an actual engine rotor.
- To invoke an alarm system.
- To activate direct speed control of the vehicle whenever alarm fails to alter the sleep state of the driver.
- The synced data of an individual from a Fitbit device has been successfully extracted in CSV format as shown in Fig 1.4
- The data synchronises with Fitbit servers every minute and returns three Integer values: 1,2,3.
- State 1: The subject is in the highest state of consciousness. “Very Awake”
- State 2: Noticeable Fatigue which will/might be followed by loss of consciousness. “Awake”
- State 3: Complete Loss of consciousness. “Asleep”
- Installation of haptic feedback using vibration motors.
- Forced Stop of Motor using special parameters from the extracted data.
