Characteristics of displays, which transmit information from machines to machine operators, have a great influence on psychological and physiological load imposed on the operators, controlability of machine and performance of the manual control systems.
Improvement of the performance of manual control systems and the reduction of the physical work intensity of operators are possible by designing the display suitable for human characteristics.
Making a geometrical condition of a display arrangement fit for physical properties of human operator and replacement of a data processing work requested for a stable control of the system from the human operator to a electronic device provided in the displays are effective method available for the improvements.
