Interaction method and interaction equipment

The invention provides an interaction method and equipment used for interaction between a user and a machine. The interaction method comprises the steps of: obtaining the parameter information of multiple sampling points on the body part of a user; converting the parameter information into the state information of the body part; and identifying the operation which the user wants to conduct to the machine by a template for specific operation based on the state information. Through the interaction method and equipment, the actions of the user and the change of characteristic quantity of the body part of the user can be converted into a system event which can be understood by the machine, therefore, when the user acts or changes the characteristic quantity, corresponding operations are executed in the machine, thus interaction between the user and the machine can be realized on the basis of rich user information.
