DISPLAY DEVICE, DISPLAY CONTROL METHOD, PROGRAM, AND COMPUTER-READABLE RECORDING MEDIUM

摘要

To provide a display device capable of displaying a trajectory of a specific portion of a program controlled control target device regardless of whether the control program is a simple sequential execution type or a situation adaptive type. A PC (10), which is a display device, includes a command value acquiring section (1131) for acquiring command values of a series of positions, which is an execution result of the control program; a position calculating section (1132) for obtaining a series of positions of the specific portion for every control period or in a plurality of specified control periods corresponding to the acquired command values of the series of positions; a trajectory data creating section (1133) for creating trajectory data showing a trajectory that passes each of the series of positions of the specific portion in order of elapse of time; an image data creating section (1134) for creating image data for displaying a spatial mode of the trajectory on the screen as an image using the trajectory data; and a display control section (1011) for displaying the image on the screen using the image data.
