Coinciding the starting and end points of the curve P' and the curve Q, uniformly extract the coordinate point sequence B and the coordinate point sequence A from the curve P' and the curve Q, and then use the longest common subsequence for the coordinate point sequence B and the coordinate point sequence A. The LCSS algorithm calculates LCSS(B, A), and sets the similarity C=

LCSS(B,A).

In some more specific embodiments, the action information further includes an action time T1; the action time T2 is determined by the start time of the user's eye action captured by the above-mentioned vehicle-mounted camera system;
