Patent ID: 8446262

Claim:
A remote control system comprising: a receiver to be equipped in a device; and a remote controller comprising a first positioning unit to obtain current position information of the remote controller, a transmitting unit, and a processing unit to transmit a control signal and the current position information of the remote controller to the receiver through the transmitting unit; the receiver comprising: a second positioning unit to obtain current position information of the receiver; a receiving unit to receive the transmitted control signal and the current position information of the remote controller; a storage unit storing a preset distance S 1 between the remote controller and the receiver and a preset angle θ 1 between a connection line L connecting the remote controller and the receiver and a horizontal plane P where the receiver locates, the storage unit further storing a plurality of applications; and a processor to execute the plurality of applications, wherein the plurality of applications comprise instructions executable by the processor to: calculate a current distance S between the remote controller and the receiver and a current angle θ between the connection line L and the horizontal plane P, based on the current position information of the remote controller and the receiver; determine whether the calculated current angle θ is less than the preset angle θ 1 , and whether the calculated current distance S is less than the preset distance S 1 ; and control the device to execute an operation corresponding to the control signal if the current angle θ is less than the preset angle θ 1 and the current distance S is less than the preset distance S 1 .
