Claim Text:
1. A method for recognizing a movement trajectory of an operator, wherein the method is applied to an electronic device provided with an antenna and a sensor, the antenna is connected to the sensor and is in a first operation mode, and the method comprises: obtaining a capacitance signal which is generated by the antenna in the first operation mode during a first time period and is collected by the sensor; generating data of a distance between the operator and the antenna during the first time period according to the capacitance signal; and analyzing the data of the distance, and obtaining the movement trajectory of the operator formed during the first time period; and triggering the electronic device to make the electronic device execute a target instruction corresponding to the movement trajectory according to a preset correspondence between a trajectory and an instruction after obtaining the movement trajectory of the operator formed during the first time period, wherein the method further comprises: after generating the data of the distance between the operator and the antenna during the first time period according to the capacitance signal, controlling the antenna to switch from the first operation mode to a second operation mode in a case that the data of the distance comprises data of a distance smaller than or equal to a first threshold, wherein transmission power of the antenna in the second operation mode is smaller than transmission power of the antenna in the first operation mode.
