A stabilizing ability, so-called stability, according to a change in body motion of a wearer is to be appropriately evaluated to achieve effective training, coaching, and fitting of athletic equipment.

Provided are a plurality of body motion sensors 40 that is attached to a wearer 1 or an arbitrary part of a barbell 1a to be used by the wearer 1 and is capable of detecting three-dimensional displacement or rotation of each part, a memory that records a detection result by the plurality of body motion sensors 40 as body motion data and stores index data holding a correlation between an amount of deviation from a stable reference value for evaluating reproducibility of body motion and an index for evaluating a stabilizing ability, an index calculation unit 117g that refers to the index data based on a reference value or a threshold acquired from the recorded body motion data and calculates the index for evaluating the stabilizing ability, and an output device that displays or outputs the index calculated by the index calculation unit 117g.

A head-mounted display device includes a motion capturing device and a display coupled to the motion capturing device. Based upon the motion capturing device ascertaining a sports-based motion carried out by a user, a computer processor in the head-mounted display identifies the sports-based motion and generates sports-based applications on the display that are specific to the sports-based motion identified using the motion capturing device. The computer processor identifies the sports-based motion by comparing the sports-based motion to a repository of sports-based motions of the user of the head-mounted display.
