Abstract
The line-of-sight direction of an operator is estimated on the basis of the posture of a front work device detected by a posture sensor, and plural display regions are set on a screen of a transparent display on the basis of the estimated line-of-sight direction of the operator. Then, the display position of a display image is calculated in such a manner that the display position is located in the display region corresponding to the kind of the display image in the set plural display regions. When the positions of the display regions on the display device change due to change of the line-of-sight direction of the operator, the display position of the display image is held if the display image is located in the display region corresponding to the kind of the display image also after the change, and a new display position of the display image is calculated in such a manner that the new display position falls within the display region corresponding to the kind of the display image again if the display image gets out of the corresponding display region after the change.
