Abstract
A projector 22 projects video onto a surface of an infrared light reflection member 26 following control by a PC 20. A detection unit 24 includes an infrared light emitter 28 and a depth camera 30. Since the infrared light which is reflected by the infrared light reflection member 26 does not return to the depth camera 30, the infrared light reflection member 26 is an area whose distance is unmeasurable. Further, a distance can be obtained outside the infrared light reflection member 26 since the infrared light is diffusely reflected. This allows obtainment of the relative relationship between the position of an outer periphery of the infrared light reflection member 26 and the position of an object 32. Accordingly, a touched position can be calculated, and a process on the basis of that is possible.
