Abstract: A surface of the terminal device is provided with three touch regions that correspond respectively to three system navigation functions, and the three system navigation functions include back, home, and recent app. The method includes, when the terminal device detects a pressure that is exerted on one of the three touch regions and whose magnitude exceeds a preset value, implementing a system navigation function corresponding to the touch region on which the pressure is exerted. In addition to common tap and touch and hold operations, the operation method can provide a force touch operation manner for a user to quickly and conveniently operate a system navigation function.
