Abstract: Provided in the present application is a method for human-computer interaction. When a user interacts with an object device, the user uses the hand holding a mobile terminal to make a gesture motion, at this moment, on the one hand, gesture motion information of the user is detected on the basis of an optical sensor that the object device is provided with, and on the other hand, motion track information, that is terminal motion track information, of the mobile terminal moving with the hand of the user is detected on the basis of a motion sensor that the mobile terminal is provided with. Then, a determination is made on whether the gesture motion information matches the terminal motion track information; and if yes, a corresponding first control is executed. Because the mobile terminal moves with the hand of the user, the motion track information of the mobile terminal uniquely corresponds to the gesture motion information of the hand of the user, and, by determining whether the gesture motion information matches the terminal track information, a reliable determination can be made on whether the gesture motion is valid, interferences from gesture motions of an irrelevant person can be avoided, and effective human-machine interaction can be implemented.
