An interactive interface system includes: a display device configured to display a picture on a display screen; and a sensor device configured to detect a position of a detection target. The interactive interface system further includes a calibration mode. The calibration mode is a mode of performing calibration between a display position on the display screen and a detection position by the sensor device, based on a detection result which is given by the sensor device and indicates a detected position of a marker present within the display screen.
