Abstract: In an information processing apparatus, a posture data acquiring section acquires output values from a motion sensor of a head-mounted display. Effective rates of acceleration are then obtained by correcting the output values based on correction formulas. A posture is calculated in reference to the axes of the motion sensor based on the acquired rates of acceleration. Thereafter, the posture of the head-mounted display is calculated by performing rotation correction based on previously acquired angle errors, the calculated posture being output to an information processing section. A correction data updating section acquires posture information based on markers of the head-mounted display imaged in a captured image, and updates correction data for use in acquiring the posture from the sensor output values through comparison with the marker-based posture information.
