Data Model and Functionality

Sensors and Prediction:

• Input Data:
  • Onboard temperature and humidity sensor
  • 3-axis accelerometer
• Processing:
  • Baseline data created by the user when the device is not in the mouth.
  • Data is refreshed every 300ms.
  • An algorithm analyzes trends in humidity and temperature changes, applying a derivative function for faster detection.
  • The movement of the data is also considered
