Apparatus and method for controlling electronic appliances based on hand gesture recognition

A device and a method for controlling an electronic appliance with hand gesture are provided to enable a user to operate the electronic appliance conveniently in a remote place by the hand gesture through a transmitter, which is worn on a finger or a hand, or held in the hand and transmits a command signal and a receiver which transfers the received signal to an internal circuit of the electronic appliance. A transmitter(11) transmits motion detection information wirelessly by detecting the hand gesture of the user in a state worn on the finger or held in the hand. The receiver recognizes the hand gesture of the user by receiving the motion detection information from the transmitter and controls the electronic appliance by transmitting a control signal corresponding to the hand gesture to an infrared receiver of the electronic appliance in an infrared signal form. The receiver includes a wireless receiver, a motion storing part, a motion analyzer analyzing/recognizing the hand gesture by comparing the received motion information with the motion information stored in the motion storing part, an input result output device, a signal converter, and an infrared signal transmitter.
