Selection of display devices used at man-machine interfaces based on human factors

The display devices used in intelligent machines are very important to exchange information between the operators and the machines online. New selection methods for the display devices used at the man-machine interfaces are proposed based on the results of both the electronic Landolt´s ring test and the electronic stress test. The electronic Landolt´s ring test checks the degradation of the visual accommodation during the contiguous visual data terminal (VDT) operation, and the electronic stress test checks the efficiency changes of the practical work during the VDT operation. The electronic Landolt´s ring and electronic stress tests were respectively confirmed to be useful for selecting the display devices used at man-machine interfaces. In addition, the combination of these two test methods is believed to be utilized for the proper selection of the display devices used at man-machine interfaces in the intelligent machines.
