Abstract: An athletic activity performance estimation device estimates an athletic activity performance index relating to an athletic activity in which a subject performs a short-time action after a predetermined waiting time using information correlated with the state of tension of the subject as tension state information, an index indicating the subject's tension level as a tension state index, and an index indicating the quality of performance of an athletic activity of the subject as the athletic activity performance index. The athletic activity performance estimation device includes a tension state information acquirer that acquires the tension state information of the subject before starting the athletic activity, a tension state index calculator that calculates the tension state index of the subject from the tension state information, and an athletic activity performance index estimator.

Abstract: A kinetic motion learning device includes an information storage unit configured to associate and store in advance a pitching motion video and pitching trajectory information for a plurality of pitches actually delivered by a pitcher on a potential opponent team, and is configured to read a set of the pitching motion video and the pitching trajectory information stored in the information storage unit, output the pitching motion video being read to a projector, output the pitching trajectory information being read to a pitching machine, and control motion timings of the projector and the pitching machine so that a time of ball release of the pitcher in the pitching motion video displayed on a screen and a time of the pitching machine launching the ball with the pitching trajectory information match. The projector is configured to project the pitching motion video onto the screen so that the pitching motion video is displayed on the screen at a motion timing controlled by the kinetic motion learning device.

Abstract: A performance evaluation device 160 is a performance evaluation device that evaluates a batting performance of a batter in a sport in which balls pitched at various velocities are visually assessed and batted and that includes a performance evaluation unit 169 that evaluates the batting performance of the batter, based on information relevant to movements of the balls obtained as a result of batting of the batter when the balls of a plurality of types of pitch are thrown at random without the batter befog informed of the types of pitch.

Abstract: A living body guidance device includes: a measurement unit 1 that measures biometric information of a user; a stimulus unit 2 that is installed in contact with the user's body and presents a tactile stimulus to the user; a database unit 3 that has a relationship between the tactile stimulus presented by the stimulus unit and the biometric information according to the tactile stimulus recorded; an input unit 4 that sets target biometric information which is target biometric information that is desired of the user to realize; and a control unit 7 that, when there is a difference between current biometric information which is current biometric information of the user estimated based on the measurement result by the measurement unit and the target biometric information, controls the tactile stimulus presented by the stimulus unit so that the difference is reduced, so as to guide the user so that the current biometric information approaches the target biometric information, based on the relationship recorded in th

Abstract: The appropriateness of a motion of a motion actor who makes a motion in response to a motion of at least one moving body other than him/herself is visualized. To display motion information of a motion actor who makes a motion in response to a motion of at least one moving body other than him/herself, an image showing one sequence which is visible or a plurality of sequences which are visible is output. In this case, a relative time which is a position on a relative time axis corresponds to a position on a specific axis of the image. The one sequence or each of the plurality of sequences graphically shows at least a position on the axis which corresponds to a moving body time that is a relative time at which at least one predetermined motion of the moving body was made, and a position on the axis which corresponds to a motion actor time that is a relative time at which at least one predetermined motion of the motion actor was made.

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.

Abstract: The motion performance of an animal that makes a motion in response to the movement of at least one moving body other than the animal, which is a subject for evaluation, is properly evaluated. The motion data of the animal is acquired by manipulating the difficulty factor of the motion which is made by the animal in response to the movement of the moving body, and the motion performance of the animal is evaluated based on the motion data of the animal. It is to be noted that the motion data contains information indicating the timing of the motion of the animal.

Abstract: A chuck device includes a chuck main body, an exchange member, an axial direction regulating mechanism, and a circumferential direction regulating mechanism. The axial direction regulating mechanism has a circumferential groove section, which extends in the circumferential direction, that is recessed into one of the chuck main body and the exchange member and a radially protruding section, which is able to protrude in the radial direction, that is disposed in the other of the chuck main body and the exchange member. The circumferential direction regulating mechanism has an axially recessed section, which is recessed in the axial direction, that is disposed in one of the chuck main body and the exchange member and an axially protruding section, which is able to protrude in the axial direction, that is disposed in the other of the chuck main body and the exchange member.
