Abstract
A method includes acquiring first and second images that are captured by imaging a first real marker with a camera when the camera is respectively at a first and second positions with respect to the first real marker, deriving a motion of an inertial sensor based on output of the inertial sensor when the camera moves from the first position to the second position, displaying a marker image corresponding to a second real marker on a display, acquiring a third image that is obtained by capturing the second real marker with the camera when a user perceives the marker image and the second real marker being aligned with each other, and deriving a first spatial relationship between the camera and the inertial sensor and a second spatial relationship between the camera and the display based at least on the first and second images, the motion, and the third image.
