1. A system for recognizing motion by analyzing a radio signal comprising:
- a radio signal transmitter configured to transmit a radio signal;
a radio signal receiver configured to receive the transmitted radio signal reflected or attenuated by the body of at least one or more passengers; and
a motion recognition processing device configured to;
i) analyze a variation amount and a signal attenuation amount of the received radio signal, ii) extract and classify a gesture according to the variation amount of the frequency of the analyzed radio signal, iii) recognize the extracted and classified gesture, and iv) perform vehicle device control based on the recognized gesture,wherein the radio signal transmitter and the radio signal receiver are mounted such that a passenger in a vehicle is positioned between the radio signal transmitter and the radio signal receiver.

6. A method for recognizing motion by analyzing a radio signal comprising the steps of:
-
transmitting, by a radio signal transmitter, a radio signal in a vehicle; receiving, by a radio signal receiver, the transmitted radio signal reflected or attenuated by the body of at least one or more passengers; analyzing, by a motion recognition processing device, distortion and variation of the received radio signal reflected or attenuated by the body of at least one or more passengers; extracting, by the motion recognition processing device, and classifying a gesture of a passenger in the vehicle based on the analyzed distortion and variation amount of the frequency of the analyzed radio signal; and recognizing, by the motion recognition processing device, a vehicle control command based on the extracted and classified gesture, wherein the radio signal transmitter and the radio signal receiver are mounted such that a passenger in a vehicle is positioned between the radio signal transmitter and the radio signal receiver. - View Dependent Claims (7)
