An electronic device that has a sensing function with no-hindrance touching is provided. The electronic device includes a casing, a touch display and a processor. The casing has an opening, and the touch display is disposed inside the opening for receiving an operation of an input tool. The touch display has a sensing surface which allows the input tool to slide smoothly over the sensing surface and the casing. The processor is electrically coupled to the touch display, and the user interface displayed by the touch display is determined by the processor. Determination can be based on contact area, pressure, detected area, temperature or detected image of the input tool. Thus, type of input tool has influence on the user interface. As a result, the convenience of operating the electronic device is increased.
