Interactively controlling a machine with feedback from a control parameter

Abstract

The invention relates to a human machine interface () for simultaneously and interactively controlling a control function of a machine (). The human machine interface () comprises a control input unit () by means of which a control parameter of a control function of the machine () can be simultaneously manually operated in accordance with a parameter input (), a parameter input unit () which can be controlled independently from the control input device () and which enables a control parameter of the control function to be manually controlled, and a parameter display unit () arranged together with the parameter input unit () and which enables feedback of the control parameter to be manually controlled. As a result, the intuitive ease of operation, the security and ergonomics are improved such that a control parameter of the control function dependent on the control function can be manually controlled simultaneously by means of the control input unit () and that the parameter display unit () enables information relating to the desired value or an actual value of the manually controlled parameter and which is present on the machine () can be fed back.
