Claim 0:
1. A projection system, comprising:
a projection device that projects drawings individually onto a plurality of work spots in a work site based on design data showing a size and a shape of the work site; and
a data processor that specifies a placing position and an orientation of the projection device in the design data after the projection device is placed in the work site, wherein:
the projection device includes:
a driver that changes the orientation of the projection device; and
a controller that controls the driver,

when drawings are individually projected onto a first work spot and a second work spot in a stated sequence, and the second work spot is outside a projection angle that is projectable by the projection device, the controller determines a direction and an amount of movement of the orientation of the projection device to include the second work spot within the projection angle after work at the first work spot is finished, the first work spot and the second work spot being included in the plurality of work spots, and
the driver changes the orientation of the projection device based on the direction and the amount of movement determined by the controller.
