Disclosed herein are methods for a multiple degree-of-freedom (DOF) motor system with reduced number of electromagnet control phases. The motor system includes a first body that is able to move relative to a second body along multiple DOFs. The first body has at least one magnetic positioner attached. The second body has a plurality of controlled electromagnets. Control signals, the total number of phases of which is less than half the total number of electromagnets, energize at least one of the controlled electromagnets to create magnetic interaction with at least one magnetic positioner on the first body, and to control the movement of the first body relative to the second body along designated dimension(s).

A method and device for controlling an unmanned aerial vehicle with a gesture are provided. A camera is arranged in the unmanned aerial vehicle, and the method includes: detecting a gesture in an image by using a gesture detection framework; judging whether the gesture is a predetermined gesture for controlling the unmanned aerial vehicle; acquiring a motion trajectory of the gesture in a case that it is determined that the gesture is the predetermined gesture for controlling the unmanned aerial vehicle; and controlling, based on the motion trajectory of the gesture, the unmanned aerial vehicle to perform a control operation corresponding to the motion trajectory of the gesture, where a correspondence between a motion trajectory of a gesture and a control operation is predetermined.
