Abstract: A method for providing a User Interface (UI) based on a touch pressure and an electronic device using the same are provided. The UI providing method of the electronic device detects a touch pressure of a single touch input through a touch screen of the electronic device, and controls the electronic device based on the touch pressure. Since various UIs can be provided based on the touch pressure applied by the user in the touch screen, user convenience and entertainment can be improved.
