Claim 0:
1. A unlocking method by using a knob, applied to an electronic device which is provided with an operation knob,
comprising:
step (1): detecting an action of the operation knob in a screen locked state in real time; and
step 2: starting an unlocking program in response to rotation of the operation knob: calculating a rotational circumferential distance of the operation knob along a current rotational direction, determining whether the rotational circumferential distance of the operation knob reaches a preset circumferential distance, controlling the electronic device to unlock in response to the rotational circumferential distance of the operation knob reaching the preset circumferential distance, or unlocking failed and returning to step (1) in response to the rotational circumferential distance of the operation knob not reaching the preset circumferential distance; wherein step (1) comprises acquiring a rotational direction of the operation knob and a rotational angular velocity of the operation knob in the screen locked state in real time, and wherein step (2) comprises: starting the unlocking program in response to the rotational direction of the operation knob meeting a preset range and/or the rotational angular velocity of the operation knob meeting a preset range.
