Dial structure, remote controller employing the same, and controlling method

A controlling method for an unmanned aerial vehicle (UAV) comprising:

• in response to a dial of a dial structure of a remote controller being rotated around a rotation axis of the dial, transmitting, by the remote controller, a first control signal initiating a changing process to change UAV information or imaging device information of an imaging device of the UAV to updated UAV information or updated imaging device information via a signal transmitting device of the remote controller, wherein the imaging device information comprises at least one of an operating mode of the imaging device, a shutter speed of the imaging device, an aperture size of the imaging device, a light sensitivity of the imaging device, or a preview image of the imaging device;
• and
• after the dial is rotated around the rotation axis, in response to the dial being pressed along a direction perpendicular to the rotation axis of the dial, transmitting, by the remote controller, a second control signal confirming the updated UAV information or the updated imaging device information via the signal transmitting device.
