In an optical motion capture system, it is possible to measure spatially high-dense data by increasing the number of measuring points. In the motion capture system using a mesh marker, intersections of lines for the mesh marker are called nodes and the lines connecting the nodes are called edges. The system includes a plurality of cameras for capturing a two-dimensional image of the mesh marker by imaging a subject having the mesh marker, a node/edge detecting section for detecting node/edge information on the mesh marker from the two-dimensional image captured by the respective cameras, and a three-dimensional reconstructing section for acquiring three-dimensional position information of the nodes by using the node/edge information detected from the plurality of two-dimensional images captured by different cameras.

The present invention provides a method capable of acquiring a physically and physiologically valid muscular strength from motion data based on a musculoskeletal model. The present invention relates to a method for obtaining muscular tension by performing inverse dynamics calculation of a musculoskeletal model. The method comprises a step for optimizing a contact force τC received from an environment using acquired floor reaction force data and a step for optimizing the muscle tension ƒ using acquired motion data, acquired myogenic potential data, and optimized contact force. The motion data, reaction force data and myogenic potential data can be measured at the same time by a behavior capture system.

A headrest device includes a headrest provided over a seatback of a seat, a sliding means for slidably adjusting the seat in back and forth directions, a position-adjusting means for adjusting position of the headrest, and a connecting mechanism connecting the sliding means and the position-adjusting means. The connecting mechanism operates the position-adjusting means in conjunction with operation of the sliding means. The connecting mechanism moves in a first direction when the sliding means moves forward, and the connecting mechanism moves in a second direction when the sliding means moves backward.

Endoscopic surgical operation such as evisceration has been so far hardly achieved by a medical robot, since it requires high power. The present invention provides a downsized high-flexibility active forceps to enable such an operation, without needing a large space for manipulation to target a limited operative area. An active forceps of the present invention comprises: a tip forceps part 4 having, a tip supporting member 2 to support a forceps tip 1 at a center section 2a with a plurality of arms 2b laterally projected therefrom, and a plurality of tip side advancing and retreating members 3 connected at a front end with the plurality of arms respectively oscillatable while connected to one another relatively movable in directions toward front and rear ends; and a forceps bottom part 9 having, a plurality of bottom side advancing and retreating members 6 each integrally coupled to the plurality of tip side advancing and retreating members 3, while connected to one another relatively movable indirections toward front and rear ends to constitute a link mechanism together with the tip side advancing and retreating members 3 and the tip supporting member 2, and a bottom frame 8 provided with forward and backward actuating means 7 for moving relatively to one another the bottom side advancing and retreating members 6 in directions toward front and rear ends.
