Patent ID: 8718608

Claim:
A mobile phone comprising a first sensing component, a second sensing component, a sensing component module, a judgement module and an unlocking performing module, wherein the sensing component module is configured to record the time at which a user touches the first sensing component and the second sensing component, and send recorded time to the judgement module; and the judgement module is configured to judge whether an unlocking condition is satisfied according to the time at which the user touches the first sensing component and the second sensing component; if yes, notify the unlocking performing module to perform unlocking, if not, maintain locking, wherein the unlocking condition in the judgement module is as follows: the time at which the user touches the first sensing component and the second sensing component is recorded as t 1 and t 2 ; if T min<|t 1 -t 2 |<T max, the unlocking condition is satisfied; otherwise, the unlocking condition is unsatisfied; wherein the judgement module further comprises a correction unit, configured to record time interval t i of each successful unlocking time, and calculate an expected time t e and a standard difference t d of the time differences of former N-time after the N th unlocking is finished, wherein t e = ∑ N i = 0 ⁢ t i ; t d = ∑ N i = 0 ⁢ ( t i - t e ) 2 ; and, reassign a value to the T min and T max by adding t.sub.e and t.sub.d with one pre-set error constant t c , wherein T min=t e −t d−t c ; and T max=t e +t d +t c .
