INFORMATION PROCESSING SYSTEM, CONTROL METHOD, AND PROGRAM RECORDING MEDIUM

摘要

The present invention projects an image that is easy for a user to manipulate. This information processing system (2000) comprises a real target object detection unit (2020), a projection unit (2060), and a state determination unit (2080). The real target object detection unit (2020) detects a real target object. The projection unit (2060) projects a first image on a projection surface. The state determination unit (2080) determines at least one of the orientation of a first image and the position of the first image within the projection surface on the basis of at least one of the orientation and the position of the detected real target object. The projection unit (2060) projects the first image using the position or the orientation that is determined by the state determination unit (2080).
