Abstract: The present disclosure provides a dynamic gesture identification method, a gesture interaction method and an interaction system. The interaction system includes: a dynamic vision sensor configured to trigger an event in accordance with movement of an object in a field of view relative to the dynamic vision sensor, and output an event data flow; a hand detection module configured to process the received event data flow to determine an initial position of a hand; a hand tracking module configured to determine a series of state vectors in accordance with the initial position of the hand; a gesture identification module configured to create an event cloud in accordance with event data corresponding to the obtained state vector, and process the event cloud to identify the gesture; and a command execution module configured to execute a corresponding operating command in accordance with the identified gesture.
