Abstract: A head-mounted display device has more convenient functions, which is usable in, e.g., surveying. An eyeglass display device includes a display unit and an operation content receiving unit. The display unit is configured to be placed on the head of a user and to be viewed by the user. The operation content receiving unit receives content of operation performed by the user. The display unit displays an image that shows a location relationship between positioning information of a target positioned by a location measuring device by using laser light and a predetermined placement planned location of the target. Multiple coordinate systems are prepared for a coordinate system of the displayed image. The operation content receiving unit receives designation of one coordinate system from among the multiple coordinate systems by the user.
