1. A projection processing device, comprising a processor that acquires, in response to acceptance of input information, projection position information associated with the input information, and instructs a projector to emit light or project an image enabling a user to identify a position based on the acquired projection position information,
wherein the projection processing device further comprising:
a detection unit that detects an obstacle in a direction in which the projector emits light or projects the image,
wherein the processor determines at least one of the projectors among a plurality of the projectors, based on detection of the obstacle by the detection unit.
