If the rotating angle does not reach an integral multiple of 90 degrees, the icon rebounds to a closer previous angle or rotates to a closer next angle in the form of animation according to the nearby principle, which is beneficial to improve a sensitivity of the screen unlocking operation and user experience thereof. For example, if the user gesture rotates the key over 78 degrees, the key stops at the 90-degree position finally, and if the user gesture rotates the key over 178 degrees, the key stops at the 180-degree position finally. Wherein, the animation needs the acceleration effect from gravity sensor. The unlocking angle can be set to be an integral multiple of 90 degrees angles such as 90 degrees, 180 degrees, and 270 degrees according to requirements from users. If the unlocking angle is N degrees more than 360 degrees, users should make N/360 turns of the icon and then set the position of the N %360-degree angle is set as the unlocking position. In the embodiment of the present disclosure, the default unlocking angle is 90 degrees.
