     DETAILED DESCRIPTION 
     Referring to  FIGS. 1-3 , an exemplary embodiment of a remote control system includes a transmitting apparatus  100 , a receiving apparatus  200 , and a computer  300 . 
     The transmitting apparatus  100  generates move instructions and key-press instructions. The receiving apparatus  200  receives the move instructions and key-press instructions and sends the move instructions and key-press instructions to the computer  300 . The computer  300  receives the move instructions and key-press instructions from the receiving apparatus  200  and converts the move instructions and key-press instructions into actions of a cursor of the computer  300  and performs corresponding functions. In one embodiment, the transmitting apparatus  100  may be ring-shaped, and can be worn on a finger of a user of the computer  300 . Two buttons  111  and  112  are set on the transmitting apparatus  100 , to generate the key-press instructions. Material of a surface of the transmitting apparatus  100  has a high infrared reflectivity character. The receiving apparatus  200  is connected to the computer  300 , and can be optionally located around the transmitting apparatus  100 , to receive the move instructions and key-press instructions from the transmitting apparatus  100 . 
     The transmitting apparatus  100  includes a power module  110 , a button module  120 , a first data processing module  130 , and a wireless transmitting module  140 . The power module  110  provides voltages to the button module  120 , the first data processing module  130 , and the wireless transmitting module  140 . The button module  120  outputs the key-press instructions via operating the buttons  111  and  112 . The first data processing module  130  receives the key-press instructions from the button module  120  and sends the key-press instructions to the receiving apparatus  200  via the wireless transmitting module  140 . The wireless transmitting module  140  sends the key-press instructions to the receiving apparatus  200 , then to the computer  300 , to control a cursor of the computer  300  to open or close menus of the computer  300 . 
     The receiving apparatus  200  includes a wireless receiving module  210 , an infrared camera module  220 , a second data processing module  230 , an infrared-house module  240 , and a universal serial bus (USB) interface module  250 . The receiving apparatus  200  is connected to the computer  300  via the USB interface  250 . The wireless receiving module  210  receives the key-press instructions from the transmitting apparatus  100  and sends the key-press instructions to the second data processing module  230 , to send the key-press instructions to the computer  300  via the USB interface  250 . The computer  300  receives the key-press instructions and converts the key-press instructions into key-press data, and then converts the key-press data into key-press actions of the cursor of the computer  300 . The infrared-house module  240  sends infrared to the transmitting apparatus  100 . The infrared camera module  220  receives feedback infrared from the transmitting apparatus  100  and captures a location and a movement state of the transmitting apparatus  100  according to the feedback infrared, and converts the location and the movement state into images and then sends the images to the second data processing module  230 . The second data processing module  230  receives the images and sends the images to the computer  300  via the USB interface  250 . The computer  300  receives the images and converts the images into movement data, and then converts the movement data into movement actions of the cursor of the computer  300 . 
     Referring to  FIGS. 4A and 4B , an exemplary embodiment of a remote control method for a computer includes the following steps. 
     In step S 1 , the infrared-house module  240  sends infrared to the transmitting apparatus  100 , the transmitting apparatus  100  reflects the infrared, when the infrared camera module  220  receives the reflected infrared by the transmitting apparatus  100 , the procedure goes to step S 2 , when the buttons  111  or  112  of the button module  120  are clicked, the procedure goes to step S 3 . 
     In step S 2 , the infrared camera module  220  captures the location and the movement state of the transmitting apparatus  100  according to the reflected infrared, and converts the location and movement state into images and then sends the images to the second date processing module  230 . 
     In step S 3 , the first data processing module  130  receives the key-press instructions from the button module  120  and sends the key-press instructions to the second data processing module  230  via the wireless transmitting module  140  and the wireless receiving module  210 . 
     In step S 4 , the second data processing module  230  receives the images from the infrared camera module  220  and receives the key-press instructions from the wireless receiving module  210 . 
     In step S 5 , the second data processing module  230  sends the images and the key-press instructions to the computer  300  via the USB interface  250 . 
     In step S 6 , the computer  300  receives the images and the key-press instructions via the USB interface  250 , if the computer  300  receives the images, the procedure goes to step S 7 , if the computer  300  receives the key-press instructions, the procedure goes to step S 9 . 
     In step S 7 , the computer  300  converts the images into movement data. 
     In step S 8 , the computer  300  converts the movement data into movement actions of the cursor of the computer  300 . 
     In step S 9 , the computer  300  converts the key-press instructions into key-press data. 
     In step S 10 , the computer  300  converts the key-press data into key-press actions of the cursor of the computer  300 . 
     In step S 11 , the movement actions and the key-press actions of the cursor are displayed on the computer  300  and applied to the computer  300 , to control the menu of the computer  300 . 
     The remote control system and method for computer generates corresponding operation actions in the computer  300  according to the free movement state of the transmitting apparatus  100 . Therefore, the user of the computer  300  can remote control the computer  300  conveniently.
