Abstract: A key triggering method is provided. The key triggering method is sensitive to trigger and suitable for fast repeated pressing. The key triggering method includes: presetting a trigger threshold; detecting, by a combination of a main controller and a sensor, a displacement stroke and displacement direction of a key; determining whether a movement distance of the key in a current displacement direction is greater than the trigger threshold; and switching the key between an on state and an off state according to a determination result. The key triggering method can sensitively identify a user's action for fast repeated pressing.
