v1.1 - Bug fix.
We brush our teeth every morning, but only few of us can brush our teeth correctly.
To kill all the bacteria from the mouth cavity, we need to know how to brush our teeth the right way.
To brush our teeth in the proper manner, we need to make UP-DOWN movements, not left-right movements. This is due to the fact that the UP-DOWN movement can clean the bacteria between the teeth and from the gum too.
The app will detect if you wash your teeth UP-DOWN or left-right. To detect this, the app uses a complex algorithm using the OpenCV library and draws direction lines (movement vectors) to show in which direction the teeth are washed, UP-DOWN or left-right.
In order the app to work, it is required for the phone to have a frontal camera.
To make the teeth brushing recognition correctly, the phone has to stay still, this can be achieved by putting the phone in a mobile phone car holder, which was previously mounted on the mirror, or on the tiles.
If you don't have a place to mount your phone, try to keep your phone still.
Remember, wash your teeth at least twice a day, for two minutes (one minute upper jaw, one minute lower jaw).
The app has also a timer, to know, for how long you have washed your teeth.
To have a good tooth brushing result, make small UP-DOWN movements, not big left-right movements with you toothbrush.
The app does not collect any user data.
