The instructions in the brain are translated into nerve signals to drive the hand muscles, and the hand muscle movements are again translated into electrical signals for input into the machine. The movement of the machine again generates signals through our eyes and transmits them to the brain, and the brain makes adjustments and the cycle repeats.
Fast or slow, this series of translations constitutes the communication between man and machine. The stronger this communication, the more the machine tends to become part of the human body.
