Claim 4:
5. The electronic device according to claim 4, wherein the preset pattern further comprises a second preset pattern, and after judging whether all of the key angles satisfy the preset angle threshold, the operations further comprise:
further judging whether lengths of all the key line segments are approximately equal within a preset error range under a condition that at least one of the key angles does not satisfy the preset angle threshold;
judging whether the distance between the first key point and the fifth key point is greater than the preset distance threshold under a condition that the lengths of all the key line segments are approximately equal within the preset error range; and
determining that the sliding track satisfies a recognition condition of the second preset pattern under a condition that the distance between the first key point and the fifth key point is not greater than the preset distance threshold.
