Abstract: Embodiments of the present invention provide a collaborative visualization system, which integrates motion capture and virtual reality, along with kinematics and computer-aided design (CAD), for the purpose of, for example, virtual training on a task. A portable motion capture system tracks the movements of one or more trainers and records full-body motion capture data for one or more trainers performing one or more tasks. A virtual reality simulator receives the recorded motion capture data and animates scaled avatars within a three-dimensional virtual reality simulation responsive to recorded motion capture data. An immersive observation system displays the virtual reality simulation, including the animated avatars, as a three-dimensional image that appears to surround one or more trainees using one or more head mounted displays so that the one or more trainees can analyze the one or more tasks performed.

Abstract: A collaborative visualization system integrates motion capture and virtual reality, along with kinematics and computer-aided design (CAD), for the purpose, for example, of evaluating an engineering design. A virtual reality simulator creates a full-scale, three-dimensional virtual reality simulation responsive to computer-aided design (CAD) data. Motion capture data is obtained from users simultaneously interacting with the virtual reality simulation. The virtual reality simulator animates in real time avatars responsive to motion capture data from the users. The virtual reality simulation, including the interactions of the one or more avatars and also objects, is displayed as a three-dimensional image in a common immersive environment using one or more head mounted displays so that the users can evaluate the CAD design to thereby verify that tasks associated with a product built according to the CAD design can be performed by a predetermined range of user sizes.

Abstract: Embodiments of the present invention provide a collaborative visualization system, which integrates motion capture and virtual reality, along with kinematics and computer-aided design (CAD), for the purpose of, for example, validating a simulation with a real-world video. A spherical camera captures real-world video at a first location. At a second location, one or more head-mounted display devices display the captured real-world video and also display a simulation corresponding to the real-world video. A motion capture system captures head rotation information for one or more users to thereby to control a pan, tilt, and zoom of the real-world video so that when a position of a user's head changes, the portion of the real-world video displayed in the head-mounted display changes accordingly. Upon user input, a computer program product selects between displaying the real-world video and the simulation in the head-mounted display.

Abstract: Disclosed is a method for quantitatively evaluating the tightness of the stator wedges of an alternator, which can be reduced to practice without having to remove or dismantle the rotor of the alternator even when the air-gap of the alternator is as small as 10 mm, and which permits to obtain a quantitative evaluation of the compression percentage of the ripple spring holding the wedges in a simple, efficient and reliable manner. This method makes use of a thin flat sensor having one face provided with a recess in which a piston is mounted. This sensor is inserted into the air-gap of the alternator and positioned in front of the stator wedge to be evaluated so that the piston faces this wedge. Thus, a fluid is injected into the sensor to bring the piston to contact and then press against the wedge while the sensor is backed against the rotor.
