강혁규, Alexandre Dubois, Martin Bois

2. SUMMARY General Architecture Device Design Mobile Application Design
Cloud Design
Project Status

3. General Architecture ES Connects using Bluetooth to the smartphone
Get the number of glasses set on the smartphone
Configure number of glasses
Enter user’s characteristics and compute a number of glasses
- Set a timer
Stores the data on two tables :
User Table
Consumption Table

4. 6 DOF Sensor – MPU6050 Calculate degree of angle with:
3-axis of gyroscope
3-axis of accelerometer
MPU6050-raspberrypi :
Python module for accessing the MPU-6050 sensor data on a Raspberry pi

5. 6 DOF Sensor – MPU6050

6. Raspberry Design Raspberry pi:
Get maximum shots from the app (via Bluetooth)
Read data from sensor.
Determine if person is drinking.
Change the color of LED.
The glass vibrates if the amount exceeds.

7. AWS Mobile SDK for Android
Application Design
AWS Mobile SDK for Android

8. Application Design 4 Activities/Layouts :
Tab Activity >> Manages the differents tabs
Set Up Activity >> Computes and suggests the amount of glasses you can drink
Checking Activity >> Set a timer and an amount of glasses
Overall Data Activity >> Compares your today consumption with your previous consumption

9. Application Design
This is the first activity, where you can simulate the amount of drinks you can get.

10. Application Design 𝑊𝐸𝐼𝐺𝐻𝑇 𝐻𝐸𝐼𝐺𝐻𝑇² =𝐵𝑀𝐼
The algorithm is based on the calculation of the Body Mass Index, which is the Weight divided by the squared Height. It gives a pretty good estimation because depending on your BMI, you will be allowed to drink more or less.
For example, a underweighted person should drink less than a Normal Weight.

11. Application Design 𝑊𝐸𝐼𝐺𝐻𝑇 𝐻𝐸𝐼𝐺𝐻𝑇² =𝐵𝑀𝐼 Other parameters
In addition there are other parameters like the gender or the type of drink. Indeed, the female BMI scale is slightly different. Furthermore, the type of drink is really important, because a glass of vodka doesn’t have the same alcohol rate than a glass of beer.
Other parameters

12. Application Design The next tab is the one where you can :
Set a timer – Set an amount of glasses – Check your number of glasses

13. Application Design
You can see the previous consumption and locate your current one.
Once you set an amount, the today data will appear on a graph of your previous consumption. You can compare it and see if you are on the average, or below of your usual consumption.

14. Application Design Notifications
Our application can also send notifications : when the time is over, it allows the user to reset his glass.
In addition, toasts messages were added to deal with exceptions like when the user doesn’t fill the form properly.

15. Cloud Design Data to store in the Cloud : Why using AWS Users data
Consumption Data
Why using AWS
Simple and very fast Databases
Powerful Android SDK
Possibility to manage users
All those data are sent to the cloud…

16. Cloud Design IAM Cognito Our two databases : -ConsoTable -UserTable
Give Cognito Unauthentified users
Access to DynamoDB
databases
Give the possibility to Create users

17. Cloud Design Code Integration DynamoDB Two mapper classes
Indicate names of Table, HashKey and Attributes

18. Cloud Design Code Integration Cognito One Manager Class
Give all the cloud required info to the DynamoDB Mapper

19. Cloud Design
Online Table : UserTable

20. Cloud Design
Online Table : ConsoTable

21. Now, time for a demo 
