 ### Motion Detection
 
-The wristband uses an accelerometer to identify its slope. Since it is attached to the user's wrist, the degree of tilt on the 3 axes (X, Y and Z) can be used to indicate whether the user's hand is close to their face or not. If a sequence of angles detected by the bracelet matches a hand-to-face movement, it will vibrate. Therefore, the mere fact that it is close to the user's face does not trigger the vibrating motor.

 The figure above shows the recurrent neural network used to predict the user's hand movements. This network is fed with the data from x, y and z axes of the accelerometer and the output of the network at the previous time. After the training, the network is able to predict a hand-to-face movement with a hit rate of approximately 90% [6].
 
-It is important to emphasize that at certain times the device may present false positives, i.e., when the bracelet vibrates in non-touch movements, or false negatives, when it does not vibrate in touch movements. User can adjust sensitivity to decrease the amount of false positives or false negatives. To adjust this sensitivity, use the wristband app described in the next sections.

 ### Switching Function
 
-Currently the wristband has two functions: **Avoid hand-to-face contact**, **chew time control** and **sleep activity monitoring**. To switch between these three functions, rotate the wristband around your wrist repeatedly as illustrated in the image below. The wristband will vibrate 3 times to indicate that function 3 (sleep) has been activated, 2 times for function 2 (chew) or 1 time to indicate function 1 (touch) has been activated. These functions are disabled by default. Configure the wristband by connecting it to a computer through the USB port.
