Abstract: A motion capture system includes a motion sensor having a flexible body and a fiber bragg gratings (FBG) sensor inserted into the body, a fixture configured to fix the motion sensor to a human body of a user, a light source configured to irradiate light to the motion sensor, and a measurer configured to analyze a reflected light output from the motion sensor, wherein the FBG sensor includes an optical fiber extending along a longitudinal direction of the body and a sensing unit formed in a partial region of the optical fiber and having a plurality of gratings, and wherein a change of a wavelength spectrum of the reflected light, caused by the change of an interval of the gratings due to a motion of the user, is detected to measure a motion state of the user.

Abstract: The present invention relates to an auxiliary registration apparatus for registering a display device and an image sensor. The apparatus includes a camera; a panel interoperated with the camera and on which a first pattern is displayed; and a control part which allows the first pattern to be shot with the image sensor and a second pattern displayed on a screen of the display device to be shot with the camera; wherein the control part allows information on a transformation relationship between a coordinate system of the display device and that of the image sensor to be acquired by referring to information on a transformation relationship between a coordinate system of the panel and that of the image sensor and information on a transformation relationship between a coordinate system of the camera and that of the display device.
