Claim 11:
12. The method according to claim 1, wherein the preset pattern comprises a first preset pattern, and judging whether the sliding track satisfies the recognition condition of the preset pattern based on the key points in the set of key points comprises:
connecting all of the key points in the set of key points in sequence according to a sequence number from the first key point to the fifth key point to determine a key line segment between two adjacent key points in the set of key points;
determining an angle between any two adjacent key line segments to obtain several key angles;
judging whether all of the key angles satisfy a preset angle threshold;
judging whether a distance between the first key point and the fifth key point is greater than a preset distance threshold under a condition that all of the key angles satisfy the preset angle threshold; and
determining that the sliding track satisfies the recognition condition of the first 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.
