A method for virtual keyboard generation which is applied to an electronic device with a touch screen is provided in this disclosure.

Finally the method generates a palm virtual keyboard according to the palm shape and the finger touch points, and displays the palm virtual keyboard at a position horizontally aligned with the palm shape. A palm virtual keyboard generation system is also provided.
