1. A remote control method using ultra-wideband (UWB) in a display device of a remote control system, the remote control method comprising:
identifying, by a display device, a first distance between a remote control and a first UWB anchor and a second distance between the remote control and a second UWB anchor;
identifying, by the display device, a first angle between a first direction based on the remote control pointing at the first UWB anchor and a second direction based on the remote control pointing at the second UWB anchor or a third distance between the first UWB anchor and the second UWB anchor;
identifying, by the display device, relative coordinates of the remote control based on the display device, using the first distance, the second distance and the first angle, or using the first distance, the second distance and the third distance; and
determining, by the display device, an orientation direction of the remote control at the time of receiving a 9-axis sensor value of the remote control from the remote control.
