Relative mouse movement	The relative mouse movement is a mouse behaviour encountered in touch screen mobile devices, in which the screen cursor moves relatively to the touch. Uncheck this option to have a mouse behaviour similar to the real desktop mouse in which the cursor will be always positioned under the touch.
Minimum Drag Distance (in Pixels)	Specify maximum distance in pixels that you can move the finger and have it be considered a touch instead of a drag movement.
Touch to hold delay (Miliseconds)	Specify time in miliseconds that you need to hold a touch until you can drag.
