1. Study of the app.


With the help of the teachers, understand the algorithm and complete the values in the report.


2. Launch the program: Build - App (Provide QR code for .apk)


3. Calibration


       a. Acceleration


What is the interest to calibrate your acceleration sensor ?


The acceleration sensor needs to detect the motion of the arm during the eating but it mustn't detect short vibrations usually done during a meal like conversation...


How to do ?


Shake the smartphone to check if the motion is detected. If "Yes" is displayed on the screen, a motion has been detected.


Adjust the slide to have a good threshold



b. Define the time between two mouthfuls.


By eating a piece of cake (it's a hard work today !), define a reasonable time that someone must take to eat a mouthful.Realize several measures to estimate it ( Really hard !)

Use the second slide to regulate this value.


3. Experimentation : Eat a new piece of cake.


      • Weight the mass of the piece and write it on your smartphone.
      • Begin to eat.
      • Verify that the app works.


4. Report and conclusion


Fill in the report and conclude on the interest of technology to help personal health.
