Abstract

A technology is provided where, in physical exercise performed using plate-shaped equipment, behavior of one's own body and corresponding behavior of equipment can be presented in an intuitively comprehensible manner on the basis of information acquired by a simple device configuration. Information indicating skill relating to a turn in a physical exercise performed by an exerciser performing the physical exercise using plate-shaped equipment is skill information. Included are an equipment behavior information acquiring unit that acquires equipment behavior information, a bodily behavior information acquiring unit that acquires bodily behavior information, and a skill information presenting unit that calculates, from the equipment behavior information and the bodily behavior information, a first skill indicator/second skill indicator that include information indicating behavior of the equipment/behavior of the body of the exerciser at a start-of-turn time, a middle-of-turn time, and an end-of-turn time, as the skill information, and presents the skill information. The equipment behavior information includes time sequence information of angular velocities relating to a travel direction/an edging direction of the equipment, and the bodily behavior information includes time sequence information of pressure at each region of the soles of the right foot/left foot of the exerciser.
