This means that wristwatches are also very sensitive to gestures such as strokes, captures and releases. You don't have to operate on the smart watch's display; you use your arm, and the smart watch will interpret the signal. Waving your hand in the air, you will let the smart watch release operating signals to other devices. 
The corresponding application can also better understand your daily activities. Let's say you drive a car, push a mixer button, or use an electric drill. Due to the different data, the watch interprets what it is doing and the application can tell you about the information.
The smart watch "knows" whether you are using an electric drill or driving a car. In this case, the researchers used an Android-based, LG G smartwatch and modified the watch's Linux kernel to capture accelerometer data at 4000 times per second.
