The present invention relates to a device for recognizing user representation behaviors based on unit behaviors recognition through data measured with a sensor. The inventive device can comprise a unit data extraction part extracting at least one unit data at sensor data, a characteristic information extraction part extracting at least one characteristic data at each unit data, a unit behavior recognition part recognizing the unit behavior by unit data through using the extracted characteristic information, and a representation behavior recognition part recognizing at least one representative behavior based on the unit behavior recognized by unit data.
