Abstract
A system is provided which can achieve reliability of a notification about a moving manner of a work machine for a worker regardless of the distance between the work machine and the worker. A sign image M is projected onto a peripheral region of the worker (for example, a ground surface which is present in the vicinity of the worker to the extent that the worker is capable of visually recognizing the sign image M) by an unmanned aircraft. The sign image M is an image which represents a moving manner of a work machine. Thus, regardless of the distance between the work machineand the worker, reliability of a notification about the moving manner of the work machinefor the worker is achieved compared to a case where the sign image M is projected onto an irrelevant place to the position of the worker.
