The utility model provides a recognition device for multi-point rotating movement for a touch control device, which comprises a detection module, a touch object number confirming module, an object rotating movement confirming module and a signal generating module. The detection module detects induction wave forms generated by touch of objects on the touch control device along at least one direction. The touch object number confirming module confirms the number of the objects touching the touch control device according to the detected induction wave forms. The object rotating movement confirming module is used for judging whether the plurality of objects implement rotating movement or not when the touch object number confirming module recognizes that the number of the objects is more than one. The signal generating module generates control signals when the object rotating movement confirming module confirms that the plurality of objects implement rotating movement and implements control operation on the touch control device according to the control signals. The recognition method and device based on the multi-point rotating movement can accurately recognize the plurality of objects and rotation actions generated by object touch.
