You can now just hover over your phone to get your job done. Simply move your hand over the screen in order to scroll or attend a call and voila....it's done !!!
You may seem quite inquisitive about how this really works and I am going to unravel things for you.
How it works:
If you are new to this let me explain how the touch screen works. The screen is divided into many equal sections where there is a constant flow of current. If you touch the screen, the electric field at that point varies. As a result your touch is detected.
Still the hover technology works on the basis of the capacitive screen. The notable difference being the type of capacitve technology implemented in the screen circuitry. There are two types of capacitive screens:
- -Mutual capacitance
- -Self capacitance
