Abstract:
1. A control method of a television set, comprising: obtaining motion locus points of a moving object and fitting the motion locus points to a motion curve; calculating angular information corresponding to the motion locus points on the motion curve; determining whether the angular information corresponding to a first locus point among the motion locus points is in the same preset range as the angular information corresponding to a second locus point among the motion locus points, wherein the first locus point is adjacent to the second locus point; and generating a control instruction to control the television set to act when the angular information corresponding to the first locus point is not in the same preset range as the angular information corresponding to the second locus point, wherein calculating the angular information corresponding to the motion locus points on the motion curve comprises: calculating a product of first sine and cosine and a product of second sine and cosine product, wherein the product of the first sine and cosine is the product of the sine and the cosine of the angle information corresponding to the first locus point, and the product of the second sine and cosine is the product of the sine and the cosine of the angle information corresponding to the second locus point, and wherein both the product of the first sine and cosine and the product of the second sine and cosine are calculated in the formula of: wherein θ represents a polar angle, N represents the product of the sine and the cosine of the polar angle, and Q corresponds to the number of times that a command is transmitted, and a plane where the polar angle is located is divided into quadrants varying with different Q.
