PURPOSE: To recognize a touch input locus without being conscious of a touch area and to execute a command by changing the contents of display information corresponding to instruction information corresponding to a prescribed input locus in an input means.
CONSTITUTION: When the system diagram of a gas turbine indicating the simulated system of a plant is displayed on a CRT display device screen, it is assumed that the HRSG system diagram of a next page is desired to be viewed since waste gas is sent to an HRSG and affects the temperature of water supply. A processing was performed by touching a next page request allocated to a part of a screen before, however, since other request functions are concentrated closely, a lot of erroneous operations by a touch position occur. Then, by plotting a touch locus as shown by mark in the figure at any position of the screen for instance, the locus is recognized as the mark and the command which is a page advancing function is issued. Thus, without being conscious of a touch position, just by plotting the mark on the screen, an operator can advance the page and the erroneous operations are prevented.
