MOTION LAUNCH GESTURES
One of the main features of Sense 6 is Motion Launch Gestures, which allows you execute a series of swipe gestures on the display as a quick shortcut to various functions. For example, a left swipe brings you to the widget screen while a swipe up jumps straight to the last app you used. Do note that this feature is hardware-dependent; it is currently only available on the One (M8). You can enable or disable this feature via Settings > Display & Gestures > Motion Launch Gestures.
These are the six Motion Launch Gestures that you can execute on the display.
