In a system and method for controlling a virtual keyboard of an electronic device, the virtual keyboard is generated and displayed on a touch screen of the electronic device. The method sets an angle threshold value, a movement amplitude and a movement direction of the virtual keyboard for each tilting angle of the electronic device. When the electronic device is in an edit mode and displays a middle keyboard area of the virtual keyboard, the method records an initial tilting angle and read the tilting angle of the electronic device. The method calibrates the read tilting angle to acquire actual tilting angle according to the initial tilting angle, and confirms the movement amplitude and movement direction of the virtual keyboard according to the actual tilting angle. The virtual keyboard is controlled to move according to the confirmed movement amplitude and towards the confirmed movement direction.
