A set of interaction handed-gestures were defined for Human-Machine Interaction (HMI) in command post according to the requirement of command tasks. Based on the statistical analysis of coordination relationship between touch points in the course of accomplishing the touch gestures, the current research designed a recognition method which is independent of hardware for these interaction handed-gestures. Finally, aimed at the definition and identification of interaction handed-gestures, some experiments had been tested on infrared multi-point touch table to verify the stability, validity and expansibility of this method.
