Abstract: An electronic device and a method of opening a user interface on a screen are disclosed, wherein the screen is capable of displaying a working window and an executing window. When a pointer is positioned on the executing window, a user interface module can generate a first sensing signal for displaying at least one item on the screen. When the pointer selects the item, the user interface module can generate a second sensing signal. When the pointer drags the item to the working window, the user interface module can generate a third sensing signal. The processing module can continuously receive the first, second and third sensing signals to open a user interface corresponding to the item in the working window, where the user interface is adjacent to the pointer.

Abstract: An electronic device and a touch control method thereof are provided. The electronic device has a touch unit, a press unit and a processing module. The press unit is disposed under the touch unit, and is used for generating a pressing signal. The processing module is electrically connected with the touch unit and press unit. When the processing module receives the pressing signal, an area of the touch unit is transformed into a pressing area.
