A location on a projection surface where visual information is not projected in a suitable manner is detected, and a result of the detection is outputted. A projection suitability detection system (100), which is an aspect of the present disclosure, detects on the basis of a captured image of an operation target object (OB) whether or not the operation target object (OB) has a projection surface that causes projection distortion and then outputs a result of the detection to an instructor (CR) end.
