1. A method implemented by a first electronic device, wherein the method comprises:
receiving, from a second electronic device, a radio signal comprising a first indication message indicating a first angle, wherein the first angle is a first included angle between a sliding direction of a finger of a user detected on a second screen of the second electronic device and a preset geographic direction;
calculating, based on the radio signal, a second angle that is a second included angle between the preset geographic direction and a first connection line, wherein the first connection line is between a first antenna location of the first electronic device and a second antenna location of the second electronic device according to a relationship of a distance between an antenna of the first device and an antenna of the second device, a phase difference between the antenna of the first device and the antenna of the second device, and a wavelength of the first indication message, wherein the second angle is an angle of arrival (AOA) calculated from the radio signal; and
displaying, on a first screen of the first electronic device, an animation in which to-be-transmitted information is transmitted according to the sliding direction when the first angle and the AOA meet a preset condition.
