In this paper a new idea for the design of man-machine systems is presented, whereby an operator can control a machine with little effort if the sensitivity vector of the state variation caused by a disturbance and the sensitivity vector of the state variation varied by the operator are linearly dependent. The paper shows how the condition whereby the two sensitivity vectors are linearly dependent is obtained, and also points out that in the event of the above condition not being satisfied man-machine systems can be designed such a way that the two sensitivity vectors approximately satisfy the condition.
