       BRIEF DESCRIPTION OF THE DRAWINGS 
       The components of the drawing are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of an electronic device with remote function. 
       The drawing is a block diagram of an electronic device with remote function in accordance with an exemplary embodiment. 
     
    
    
     DETAILED DESCRIPTION 
     Referring to the drawing, an embodiment of an electronic device  100  is illustrated. The electronic device  100  may be a wearable device or a handheld device, such as, a wristwatch, or a mobile phone. The electronic device  100  can remotely control peripheral devices (not shown), such as TVs, or RC cars. 
     The electronic device  100  includes a motion sensor  10 , a storage unit  20 , a processing unit  30 , a remote signal generating unit  40 , a transmitting unit  50 , and a display  60 . 
     The motion sensor  10  senses movement of the electronic device  100 . The motion sensor  10  can include an acceleration sensor. The acceleration sensor may be a two-axis or a three axis acceleration sensor. The motion sensor  10  can further include a gyroscope. 
     The storage unit  20  stores a control table (shown below). The control table records a number of remote controlled devices (hereinafter, RC devices), a number of movements of the electronic device  100 , and a number of control commands. Each RC device is associated with at least one of the movements, that is, each RC device can be controlled to execute at least one function by at least one of the movements of the electronic device  100 . Each movement corresponds to one control command. The same movements associated with different RC devices may correspond to different control commands. As shown below, the first movement associated with the RC device A corresponds to the first control command, and the first movement associated with the RC device B corresponds to the third control command different from the first control command. That is, if the electronic device  100  is employed to control the RC device A, the first movement of the electronic device  100  controls the RC device A to execute a function. If the electronic device  100  is employed to control the RC device B, the first movement of the electronic device  100  controls the RC device B to execute another function.

     The processing unit  30  is configured to display a user interface (not shown) on the display  60  for users to select a RC device. The processing unit  30  is configured to determine which RC device is selected, and search in the control table to determine the control command the sensed movement of the electronic device  100  corresponding to according to the sensed movement and the selected RC device, and further configured to control the remote signal generating unit  40  to generate a remote signal corresponding to the determined control command. The transmitting unit  50  is configured to transmit the remote signal to the selected RC device to control the selected RC device to execute a predetermined function. 
     With such configuration, if the electronic device  100  is moved according to predetermined movements, the electronic device  100  can conveniently control a selected RC device. 
     For better understanding the present disclosure, an example is given to illustrate the present disclosure. In this example, the electronic device  100  is a wristwatch on the wrist of a user, and the selected RC device is a TV. The movement of the wrist to the left, that is, the movement of the wristwatch to the left, is predetermined to turn on the TV, and the movement of the wrist to the right, that is, the movement of the wristwatch to the right, is predetermined to turn off the TV. If the wrist moves to the left, the motion sensor  10  senses the movement of the wristwatch. The processing unit  30  determines that the movement of the wristwatch is employed to turn on the TV according to the control table, and controls the remote signal generating unit  40  to generate the remote signal for turning on the TV. The transmitting unit  50  then transmits the remote signal to turn on the TV. If the wrist moves to the right, the motion sensor  10  senses the movement of the wristwatch. The processing unit  30  determines that the movement of the wristwatch is employed to turn off the TV according to the control table, and controls the remote signal generating unit  40  to generate the remote signal for turning off the TV. The transmitting unit  50  then transmits the remote signal to turn off the TV. 
     Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
